Best light meter of 2018
Customers need to be careful on how they spend their money on these products. Check them out and decide which one suits you the best to splurge upon. After carefully examining the reviews and ratings of the people who have used them earlier this listicle has been made. The “Total” indicates the overall value of the product.
Test Results and Ratings
Why did this light meter win the first place?
I was completely satisfied with the price. Its counterparts in this price range are way worse. I really enjoy the design. It is compact, comfortable and reliable. And it looks amazing! The product is very strong. Its material is stable and doesn’t crack. I don’t know anything about other models from this brand, but I am fully satisfied with this product.
Why did this light meter come in second place?
This is a pretty decent product that perfectly fitted the interior of our office. I like this product. For such a low price, I didn’t even hope it to be any better. It’s decently made. Seems that the material is good. It has a very beautiful color but I don’t really like the texture. Managers explained me all the details about the product range, price, and delivery.
Why did this light meter take third place?
This price is appropriate since the product is very well built. It doesn’t squeaks nor bents. Looks great in my apartment. I hope that the good reputation of the manufacturer will guarantee a long-term work. I liked the design. We’ve been using it for 2 months and it still looks like brand new.
light meter Buyer’s Guide
Digital cameras work out the exposure by measuring the light reflected from your subject towards the camera. This works well enough most of the time, but it falls down when you’ve got a especially reflective subject, like a white wedding dress, or a non-reflective one like a black cat. That’s one reason why all cameras have EV (exposure value) compensation controls, so that you can correct the exposure when it’s not quite right.
But old-school photographers and cinematographers know there’s another way – you measure the light falling on your subject instead, using a specially-designed translucent dome attachment with a hand-held meter. Taking these ‘incident light’ readings is more fiddly but measures the thing you really want to know – how much light is falling on your subject, not how much it’s bouncing back.
Cons: No Bluetooth
The most significant of several recent developments by Quarq is the switch to accelerometers in place of a magnet for cadence. It makes installation much easier because you’re simply fitting another crankset. Pairing is easy anyway, and helped further by the thoughtful inclusion of an LED status light and the ANT+ ID on the outside.
Quarq meters measure power at the spider, like an SRM. It’s a good method as it means the expensive and fragile bits are tucked neatly away where they’re hard to damage. It does mean that left and right power can’t be measured independently but Quarq has beaten SRM to a trick by using crank position to calculate the effort from each leg. It’s just as good and always gave the same split as whichever power meter pedals we were running.
Another crucial feature is Quarq’s ‘10K’ temperature compensation algorithm. Older models were more vulnerable to temperature variation but this one has it covered. You should still do a pre-ride manual zero offset but after that the Elsa RS does it all.
Over hundreds of miles the Elsa RS never put a foot wrong. It responded quickly, tracked well with other meters, caught sprints well and never gave us any grief. In short, it’s brilliant.
Con: Limitations of left-only
When it launched, Stages was unique for being a left-side-only crank based meter. This design makes it more affordable, less complex and easier to fit. Power is measured with strain gauges factory-bonded to a left crank, doubled and then sent to a head unit via ANT+ to a computer or Bluetooth to a smartphone app. It’s also super-light: this one was just 20g more than a regular Dura-Ace crank, making it the lightest on test.
The limitation of a left-only system is that it can’t account for a difference in your left-right power balance and very few people are truly 50-50. What’s more, your balance isn’t consistent. A bit of muscle tightness in one side will skew your balance slightly, easily creating errors of as much as 6%. To non-power meter users that may not sound like much but to long-time users a 6% error in a time trial or interval session is a big deal. Add in a real injury and your data will be way out. That said, Team Sky uses Stages and have just renewed their deal.
We got good data that tracked very closely with other meters in simultaneous testing. It caught sprints well, too, which we didn’t expect from a lefty.
For the first two years or so of production the battery cover was a weak spot, leading to problems and earning Stages a reputation for being fragile. But this has now been beefed up, and having used both we can say it’s much more robust. While this Dura-Ace version faces stiffer competition, the 10and Ultegra versions are still untouchable as affordable introductions to training with power.
Cons: Obvious limitations of wheel choice
Lighting is everything. And the way each photographer articulates his or her light determines their success both as a photographer and as an artist. Whether you’re a photojournalist using the drama of available light, or a portrait photographer who feels naked without strobes, lighting is the one constant that underlies all photographic work. Digital, true to form, has altered the ways in which you use light and the various technologies associated with its production. “Adding a handheld meter to the equation means the photographer is looking to use the information the meter provides to ‘craft’ the shot,” says PHIL BRADON, product marketing manager, Sekonic (distributed by MAC Group).
Ending up with a meter Bradon describes as “surprisingly simple to operate,” the C-500 incorporates an additional photocell filtered to read the red that digital cameras record. Thus engineers created a new processing program to adjust the way the green and blue filtered photocells process data.
Added accuracy means shooting what your eye can see. And if you trust your artistic vision, then adding a light meter to your gear box might not be such a bad idea. In fact, it may be one of the brightest ideas you’ve had this year.
Take a look at this chart
Notice the sun emits light in many wavelengths that most don’t consider “Light”, they are not things we usually think of as light. That’s right, radio waves, x-rays and infrared are all “light” and come from the sun.
It’s important to use a light with a wavelength that actually has a biological impact on the issue you are trying to solve. We want the right type of photons hitting our body. Some lights actually use a white or blue wavelength of light and add a red filter. In other words, the LED driver is based on blue light and it only looks red because there is a red filter over the light. We want pure wavelengths of light, not just a red filter that might not give off enough red light in the wavelength we want. Other lights do use a true red wavelength but use one that has not yet been shown to be biologically helpful.
This chart pulled from the Joovv site shows that one of the receptors of light energy in our body, Cytochrome C Oxidase, absorbs many more photons at certain wavelengths.
I was able to spend an hour talking with Dr. Michael Hamblin from Harvard, one of the foremost researchers on photobiomodulation and we discussed wavelengths of light.
The most beneficial of these peaks are in the range of 660-670 nm and 830-850 nm. These wavelengths have been proven to produce substantial improvements in cellular function with a wide range of resulting benefits including improved skin health, enhanced muscle recovery, reduced joint pain, increased testosterone, and even weight loss! Alternatively, other wavelengths such as 700 nm or 720 nm have almost no biological effects. So, it’s critical to choose a device that delivers optimal wavelengths of light.
So, it’s critical to choose a device that delivers optimal wavelengths of light.
It has also been shown that Red light can penetrate 15mm into the body at 694nm wavelength.
I asked Dr. Hamblin if it was possible that synergies between multiple wavelengths would increase the benefit of a healing light device over one without such synergies.
Synergies between multiple wavelengths have not been well studied. However, Dr. Hamblin agreed that a combination of NIR and Red light worked well together and it’s possible there could be synergies between wavelengths but this isn’t something he has studied.
Dose matters. A lot.
Dr Hamblin recommends everyone, especially practitioners, but also those using photobiomodulation devices purchase a light intensity meter. Without this tool, you would have no way of knowing the total energy and intensity of the device, nor how far away to keep it from your body.
Mercola and Dr. Wunsch indicate that an intensity of 10-20 mW/cmis ideal, while Joovv and some research studies argue 50-100 mW/cmare better. I believe both ranges work. Remember that more is not better.
Dr. Hamblin talks about the biphasic dose-response curve. Too much light has a negative consequence and too little may do nothing.
A Biphasic Dose Response means that if you use too little you won’t get an effect and if you use too much you will get a negative effect. You need just the right amount. Using too much, too high an intensity, too long of a time under the light can be worse than no light at all.
It is not understood why the negative effect from PBM happens, but it could be due to too much ROS (reactive oxygen species) being created in the cell.
According to Dr Alexander Wunsch and Dr Jack Kruse, LED lights can flicker and this can cause biological stress. Most of us do not notice the flicker of LED screens on our devices or LED lights in our homes and offices. But our brains may pick up on this flicker and cause stress.
LED lights flicker because with alternating current the LEDs (light diodes) are turning on an shutting off many times a second as the current changes directions.
I took a slow-motion video of my Christmas tree lights vs the Joovv and Redjuvenator to find out. Often using slow motion on a camera, we are able to show the flicker effect.
Dr. Hamblin mentioned that pulsing of LED lights studied in the lab showed more benefit than constant photon flow and also said that flicker should not be an issue in PBM. Admittedly, he did not know much about flicker. But his belief is that pulsing light is more effective and therefore flicker in a light panel may possibly be a good thing. Remeber, it’s not good for working or general lighting to have flicker, but for short time use as light therapy, it might be worthwhile. None of the lights I tested appeared to have flicker.
If you have to supplement, you want to supplement with some of the important the missing components of indoor lighting. Red, infrared, UVA and UVB are missing in indoor light and can be supplemented.
Before using or buying a device, ask yourself what benefit you are looking for.
Chronic health concerns vs vanity concerns like wrinkles, age spots and collagen may require different criteria in a device.
Do you want to reduce aging, wrinkles, increase collagen? Light in the 630-660nm wavelength stimulates cytochrome C oxidase and has effects on improving mitochondrial function and visual signs of aging.
Do you want help with improving mitochondrial function? You want red light in this wavelength 630-670nm and 830-870nm.
Be sure to know the intensity of the light so you know how long to use it.
It’s been proven that red light therapy can
Second, the intensity of the light matters. Lower intensity light will have less effect and take a much longer time to benefit. Higher intensity light will penetrate the body deeper and take less time to be effective.
While there are many devices out there, we only list those for which we’ve had experience and talked with the founders and scientists in the companies.
Joovv was developed by two couples who include medical device professionals. After paying high fees for using a red light device at the spa, the Joovv was put into development as a lower cost light device for use at home. The name actually comes from a combination of rejuvenation and domain names that weren’t yet purchased.
Joovv based their light design on scientific studies of LLLT. Joovv is transparent about the wavelengths and intensity they use and have made a rugged and effective device.
In addition, Dr. Michael Hamblin is on their scientific advisory board and supports that the Joovv is an effective light for PBM.
The Redjuvenator was developed by Leanne Venier, an engineer, artist, and student of energy medicine and eastern medicine.
The Redjuvenator has many hundreds of testimonials claiming great benefits from use including healing sun sensitivity (people who always need to wear sunglasses) to healing rashes, muscle pain, and speeding recovery. Some users claim that it works well to induce sleep and cure jetlag. Leanne Venier, the inventor of the Redjuvenator, has a private Facebook page where people post their results using her devices. There are certainly lots and lots of positive testimonials.
This panel contains two undisclosed wavelengths of RED light and one undisclosed wavelength of infrared light. Leanne will not disclose the wavelengths of light that she uses. She claims that they are effective but not well studied in the literature.
Because we do not know what the wavelengths are, Leanne keeps them secret, we cannot make claims pointing back to the scientific literature. However, Leanne is very well read in the literature, the physics, and in energy healing and Eastern medicine. We believe her when she says that the wavelengths she uses are effective and the testimonials on her Facebook page and website support this.
Redjuvenator Woo Factor
Here’s where The Redjuvenator differs from all other lights. Leanne adds “quantum healing codes” and her knowledge of eastern medicine, energy medicine, and color into her light design. She claims this makes it far more effective than traditional lights that are based only on what’s been studied in the literature. Often the literature studies focus only on what NIH (National Institute of Health) funds and may exclude testing effective therapies for many reasons.
Leanne claims her panels are low EMF but did not provide any indication of how she engineered that into the panel. In my testing, the electric field was very high, while the magnetic field was lower than Joovv and the single Suana Space light and about the same as the Sauna Space EMF Sanctuary Sauna.
RedLightMan is a company based out of UK, founded in 201after the owner thought red light devices on the market were underpowered and too expensive. They have decent information delving into the PBM science on their website and appear to make a good product.
I have not personally used one of their lights. A friend of mine has one of their lights and it’s the one with wavelengths in it.
Are wavelengths better than 2? It’s hard to say. Dr. Hamblin says the wavelengths they use are so similar that likely the added wavelengths do not do anything beyond what wavelengths would do.
Developed by Dr. Jack Kruse and Ruben Salina, the Quantlet is an evolutionary design in wearable technology that is designed to use PBM on your wrist. We wrote an entire article on The Quantlet. We think it’s the right direction and sorely needed in our modern world. At this time, warranty and quality issues are keeping us from wholeheartedly backing the device. If Quantum Dynamics, the company selling the device, steps up quality and customer service, we will review it again.
That being said, there are many users, device quality issues or not, that swear by the life changing and healing benefits they have received from using it. The Quantlet uses frequencies of light that are critically important in ALL life, ultra-violet (UV) and infrared (IR). These two light frequencies can be captured by water and drive numerous processes in the body that maintain health. Without these two frequencies, we do not thrive, we are left open to disease and increased aging.
The Quantlet also claims to help keep the body at its preferred temperature so that it can operate more efficiently. When the body overheats due to training or disease, physical performance, and cognitive function decline.
The exposure looks nice and healthy for the contents of the scene. But what does the camera say I should do? (By the way, the difference between 1/50 and 1/4shutters is negligible when it comes to exposure readings).
Exposure set according to the full auto mode in the camera.
Hmm, interesting. According to the brains of the camera, the previous exposure was underexposed by about 1/of a stop. Fortunately, nothing in the scene is clipped, and since I was shooting in stills mode, I can use the RAW file to process the image correctly.
My Thoughts On The Results
Although bigger screens are in vogue, you’ll still find a wide variety of display sizes. And size is only part of the story, as narrower aspect ratios are making big-screen phones easier to use with one hand.
Small Screen (Inches or Smaller) are compact and powerful.
Google Pixel XL
If possible, test the phone you plan to buy to make sure it captures images quickly enough; some midrange and lower-end phones suffer from lag. And if you plan to shoot a ton of photos and video, look for a handset with a microSD card slot.
A good processor inside a phone should translate to faster open times for apps, smoother gameplay and quicker photo editing, but you don’t have to pay attention to cores or clock speed. It’s better to look at the performance results in our reviews, such as Geekbench, which measures overall performance, as well as real-world tests we run.
The Apple iPhone X features the powerful A1Bionic processor.
Right now the fastest mobile chip (by far) is Apple’s A1Bionic processor, which is inside the iPhone X, iPhone and iPhone Plus. For example, the A1took only 4seconds to edit a 4K video, compared with nearly minutes for the Pixel and more than minutes for the Galaxy S8+.
Given that some games can easily take up more than 1GB of storage — not to mention how many high-res photos and videos smartphone owners are capturing — we highly recommend opting for as much internal storage as possible.
A microSD card can help expand your storage. It’s available on many Android phones, but Apple’s phones don’t offer this option.
We consider any phone that lasts longer than hours of straight 4G LTE surfing to be very good.
If you want to be able to juice your phone up in a hurry, check to see whether your phone offers fast wireless charging. For instance, Google says the Pixel will give you hours of power in just 1minutes. If you’re shopping for an Android phone, you might check that it supports Qualcomm Quick Charge 4.0 (or an earlier version of the standard).
Removable batteries have fallen out of favor with most smartphone-makers, especially with more users demanding water resistance. But there are some benefits to this kind of design. Once your existing battery stops holding a charge for as long as it did when it was fresh, you can just swap in a new one without having to pay for a replacement service or a new phone.
ZTE Blade V8
The disadvantages of going with a smaller prepaid carrier include a more limited selection of smartphones (in most cases) and paying full price for the handset. While MetroPCS, Boost and Virgin matched the performance of their parent networks in our testing — Boost and Virgin are Sprint subsidiaries — Cricket’s 4G speeds are notably slower than parent company AT&T’s. And carriers reserve the right to deprioritize prepaid traffic if there’s a lot of congestion on their network.
When I first started in this business, I mentor of mine suggested that one of the first tools I needed was a decent multimeter.
Though I owned a multimeter, I clearly didn’t see the “multi” in it! It was like when I first got my Leatherman and only used the knife and pliers! All of the other symbols and letters on the dials was just greek to me, but boy would I learn! continuity and amperage and exactly how to test and/or troubleshoot all of these in various scenarios and situations.
And that they’re different.
Though I’m not going to go super in depth here on how electricity works, AC voltage is what we in America use for “wall power” and DC voltage is what most electronics convert power to to use, and all car/boat/rv/truck power runs on DC current.
We can measure voltage using out multimeter very easily. First, setup your probes where indicated on the meter for the type of current you are measuring. Some meters will be “auto-ranging” and will move the “scale” of voltage that you’re measuring automatically. Others will display “overload” or a very small number when you get out of range in either direction, and you can adjust your range on the dial.
These are the basic functions that I use on my meter on a weekly basis in stage lighting, and hopefully this guide has taught you something new that you didn’t know about your meter, or perhaps has influenced you to buy a meter yourself.
If you don’t buy an auto-ranging meter, you’ll have to move your dial around and watch the meter re-read the signal every time you go and meter something.
Backlight and Screen
It’s a good idea, but I’m not gonna go out and say it’s essential.
But, it is nice when you’re metering power in a dark corner or closet and you can just click the button and have a great view of the screen.
It’s benefits include auto-ranging, protective rubber corners, a nice big digital display and a great price! Naturally, this meter feels cheap to the touch, and you should take care of it.
But, for the price it’s a great value and perfect for someone who’s just starting out.
The Tenma 722is a great meter.
It is the meter I own, and it comes with a case(no stand), has that clamp for ampacity metering, and is tough! It’s got true RMS metering, and does everything I need it to do.
It’s a little pricier, but if you make your living taking care of expensive electrical equipment, it’s totally worth every penny! The only thing that really bugs me occasionally is the lack of the backlight.
The High End
I know many people don’t care about comparing features or understanding technical details; they just want a simple answer to their questions. If you don’t already have a camera, here are my recommendations. If you do already have a camera that’s a different make than I recommend, feel free to buy the lenses I recommend for your camera body.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
Most important, have fun and choose your light meter wisely! Good luck!
