This is the complete review of the Yongnuo YN-900 Bi-color LED light panel.
Before reading and watching the review, it is important to first understand the goals of the review. Here are the important questions I wanted answered:
- Does the Yongnuo YN-900 bi-color LED panel sacrifice quality due to its low price?
- Is the CRI rating of 95+ accurate?
- Is the light output of the fixture really that high? The theoretical specification is unrealistic!
- Can you record audio with the fan noise?
- Are the bi-color color temperatures accurate and usable?
- Can it be used for high frame rate (HFR) video?
Let’s get started.
Important: Prices, specifications and my observations and analysis can be totally wrong or incorrect. Please refer to the manufacturer’s website for correct information.

Yongnuo YN-900 Bi-color LED Light Panel Review
Watch my entire review:
- There are some differences in the color charts under different color temperatures. I think my eyes were tired after weeks of work. However, these differences can be attributed to normal variances, and only show their true colors (pun intended) when my face was lit. By the way, I’m squinting like Inokichi in Yojimbo because two lights are at full power a foot away from either side!
- The light is really beautiful with a shower curtain, and has enough punch for most interviewing situations as a key light. The green tint might be removable with a color filter, though I haven’t tested it.
Notes and specifications from the review
Here’s a quick look at how the unit performed against an Arri-clone 650W fresnel:
|Setting||Actual Color Temperature||Output^|
|Full Power (both)||4000K||6000 lux|
|650 W fresnel spot||3200K||6000 lux|
|650 W fresnel flood||3200K||3000 lux|
|Diffusion||Reduction||Change in color|
^At f/2.8, 1/50th shutter, 1oo ISO, 25 fps @ a distance of 6 feet. White balance measured using the A7s.The unit ships with two diffusion panels. Here’s how they stack up:*When combined with the 5500K setting. For the other two settings the white balance fell beyond the camera’s ability.Some other important specifications and features you should be aware of:
- Weight: 1.48 kg
- Dimensions: 260 x 188 x 48 mm
- Wireless control – Remote and app (both Android and iOS), up to 8 groups
- Wireless control up to 65 feet (tested up to 40 feet with a wall in between, so does not require full line of sight, but it might under different conditions)
- Batteries – Sony NP-Fseries, minimum 4000mAH each. Needs two batteries to work.
- DC adapter can be generic, 19 V 5A
- Power draw: 54 Watts
- Lumens: 7,200 lumens – this is phenomenal!
- High frame rate: Possible, tested to 120p
A quick comparison of the Yongnuo YN-900 against the Litepanels Astra and ‘normal’ 1×1 bicolor:
|Feature||Litepanels Astra 1×1||Litepanels 1×1||YN900|
|Light output 5500K (lux)||3180||490||3000|
|Light output 3200K (lux)||2610||490||3000|
|Light output both (lux)||n/a||n/a||6000|
My intention is not to belittle the Litepanels LEDs, because they are staples of the industry for good reason. Still, this is an eye opener (all are bi-color units):Like I said in the review, the YN900 is too cheap for what it offers. You could easily buy seven of them for the price of one Litepanels fixture. At half the power draw. And double the light output. At half the weight. And Yongnuo has been around for along time.
Just imagine, you can use 10 YN900s to get the same light output as 10 650 W fresnels, but at only 540 W! The fresnels will need 6,500W!! And a lot of air-conditioning…and tissue paper…and bulbs…and first aid.
The YN900 is cheaper, and is rated to run for 50,000 hours. If you’re shooting 4 hours a day for 150 days a year, that’s 83 years. Even if it’s only 10,000 hours, that’s 16 years.
The Yongnuo YN-900 bi-color LED panel is brilliantly made, and for its price and features, unbeatable. Unfortunately, it also digs its own grave by having a fan that does three cardinal sins:
- Raises the decibel level by 2-3 dB.
- Is most loud at 1200 Hz, and also has other frequencies that interfere entirely with speech, so is difficult to remove.
- Worst of all, it starts and stops at will, and is unpredictable. Due to this, there’s no constant ‘hum’ (it’s more like a whine) that can be easily removed in post.
For productions that involve recording audio, I cannot recommend this unit. For everything else, there are few others that are better at this price point.Make no mistake. This unit offers tremendous value for money, so many are likely to ignore the audio issue hoping for the best. Don’t say I didn’t warn you!
Personal take: I don’t prefer LEDs, mainly due to the color cast even after white balancing them; and also the fact that they’re hard to control. The newer fresnel LED units are way too heavy and large with their massive heat sinks. But things are changing fast!
Well, that’s the end of my review. I hope you have found it beneficial for the kind of productions you’re doing.If you need any clarifications, let me know in the comments section below.
