This is how I solved the problem - replace the fan with a quality one. https://youtu.be/W57TGcwMUBY

Use the remote that came with your YN 900 or the smartphone app for the 900 or 600

Yes, it's slight but it is something to be aware of. The fan kicks on when it wants so place microphones away from the light and the little bit of noise should not register.

The variable temperature YN900LED has a lower light output because the diodes are in two banks. One at the same color temp as the single color temp light and a second bank at 3200k. At a color temp of around 4300K the light outputs are similar as both lights have their leds at full strength.

One at the same color temp as the single color temp light and a second bank at 3200k. At a color temp of around 4300K the light outputs are similar as both lights have their leds at full strength. The dual bank light achieves various color temps by adjusting the intensity of the two varying banks of diodes. If you are shooting video you might like extra brightness of the single color temp, but if you are trying to match the color temp of existing light for a more balanced and natural look the variable temp light is very handy. I like the spectrum of the variable temp light better for still photography and I can always shoot at 4300K when I need max light output. I currently own 600s, 900s, and 600 Air variable temp Yongnuo lights. I may soon pick up a couple of 1200 variable temp lights. I my experience they perform well for events and location work where power and weight are sometimes very important. see less

I've not used the YN1600 but theYN900 has always been enough for my needs,

Hi Friend, our YN900 don't include the batteries, and you need to buy the batteries seperately.

Half the bulbs are daylight temp Half are Tungsten temperature. You have dimmer controls for each. With both turned up to 100% this light is very bright. Brighter than the pro standard bi color 12x12 Lite panel and much more afordable.

Hi Dalibor Zaviska, thanks for your asking. Our YN900's CRI number is > or = 95. If you have any other questions, pls feel free to contact us.

Have been using two of these for a few weeks now -- have used them for formals for a couple wedding, extra lighting in a very dim reception hall. main lighting for glamour stills and video, and fill for environmental portraiture. In every case performance has been superb. These lights have far better performance, features, and quality than they have a right to for the price. Lots of unexpected and pleasant surprises. For example, they come with an rf remote control that lets you power them up, adjust overall output or color temperature remotely. Because you can set the channel for each light, you can either control all the lights at the same time, or assign separate channels and address each light individually. What I really love is that the lights talk to each other, even without using the remote control. So, for example, if more than one light is on the same channel, if you turn on one light, they all come on. Dim one light, and they all dim simultaneously. Amazing. I don't have the means to measure CRI, but the quality seems very high compared to smaller, cheaper LED lights I've used in the past. I have shot video at 24, 30, and 60fps and haven't detected any flicker. The lights are a little beamy with somewhat uneven coverage and some hot spots -- you will never confuse one of these lights with a 48 inch softbox. But when I say a "little" beamy I mean just that -- in practice it's not noticeable in the final images. As others have noted, the barn doors are very thin cheap metal, and they ding and bend easily. It won't take long for them to look like they've been years in a busy NYC rental house inventory. But they work, and also protect the LED array when traveling, so who is going to complain. They use Sony LI ION video batteries, and battery life is really good. One thing I have noticed though -- if you leave the battery attached but the light "off," there is still significant drain, and after a few days of just sitting unused on a light stand, they will completely drain the battery. So keep the batteries off the lights when not in use. The nightstand adapter furnished by the manufacturer is a bit quirky -- it make a great handle for hand-held use, but put it on a light stand, and there is no tilt ability, which is annoying. I solved the problem by equipping each of my lights with a Manfrotto 026 Swivel adapter, which adapts to a variety of light stands and is built like a tank. In the studio, I mount the lights on any convenient stand -- for location use, I have found the Manfrotto 5001B 74-inch Nano Stand to be the perfect match -- the stand collapses to an amazingly small size, allowing several stands and lights to be brought on location in a very small Pelican case or soft bag. I have not had an opportunity to compare these to the $1K+ 1x1 pro lights. But my gut feel is that these are closer to the performance of the bigger lights than you might think. Turned nearly all the way down, these things are brighter than my old camera-mount LED lights -- turned all the way up, and you can use them for daylight fill. REALLY bright! My only real quibble is the UI is a bit clunky -- you can't set a color temperature and then ramp brightness up or down. Instead, you separately adjust the output of the daylight and tungsten LEDs. Which is a pain in the you know what. It works, and with care you can match the color temp to just about anything while achieving the brightness level you want, but it's an annoying process. I'd much rather be able to dial in the color temp I want, and then ramp the overall output up and down simultaneously. Who knows -- maybe in Rev 2 or 3. All in all, a great light for both still and video photography that lets you bring powerful, flexible, wireless lighting with you wherever you go. Reliable and high quality, these are a game changer for photographers and videographers looking to have professional-level lighting gear without spending thousands of dollars. The perfect entry point into LED lighting!

This is an exceptional light in almost every way. It is wonderful to sit behind the camera and with your phone, make adjustments to the brightness and color temperature. I have been using these for about a year and a half and just love them. But, they have a few issues which require a work around. First, they are not very soft. The barn doors are worthless for actually blocking light, but they are WONDERFUL for holding diffuser to make a much softer light. I picked up a couple of these and just hang them around the barn doors: For interviews, the fan noise is just unacceptable. I was living with it and trying to keep the lights dimmer and closer, so the lights would not get warm and the fan never kick in. But sometimes, you want more brightness and when they kick in, the noise will clearly be heard. Finally, I replaced the fan in the back with a good one. WHAT A DIFFERENCE! Yes, it's another $15 and 30 minutes of your time, but well worth it. To learn how, head over to YouTube and search for "Yongnuo YN900 HACK - Loud Fan Fix"

Awesome light but needed to replace the cheap fan, which is noisy and comes on automatically (can't control when). Used a Noctua a-series cooling fan from Amazon and a video I found on YouTube that walks you through it. Works just great now - love being able to control it and my other YN300 lights on my phone or iPad with the app (app takes a while to "pick up" the lights so be patient but works great one it can reach them).
