I've been using these bulbs for a few months now and only use daylight/tungsten for videos. Most of the time, they're great: light, soft, and wide with a lid and don't get hot. But I have three problems: - The biggest problem is that when the lights are on 100%, they randomly dim and brighten. intervals. I'm sure it's not that big of a problem with photography, but it's still my biggest problem with light. Turning your headlights down to 80-90% doesn't change the brightness (at least not for me yet). - The stands tend to tilt, especially at full height due to the weak legs, but they still get the job done. .- And finally, the back of the lights makes a faint whistle (like a dog whistle) but luckily you won't hear it unless you're within 30cm of the lights. All in all, these are great/flexible first lights to get. I am leaving 4 stars instead of 5 because while they are great they are not perfect. Again, I haven't used the RGB mode extensively, so this review isn't for it.
