I ordered a pair of these with a mounting kit for my P3P--I'm quite pleased with how bright they are, and how you can program them for many functions including frequency of their strobing. However, when using them at full intensity as a continuous light (not flashing, strobing etc); one of them would cut out (momentarily) after three minutes--even when cooled in water, or experiencing "wind-chill" from the prop wash from the flying P3P. It would turn itself back on for a couple seconds after turning itself off for about a minute each cycle. The other would also shut off temporarily after about 10 minutes--but that seemed to be it's own self protection for overheating. I emailed technical support, and they were very helpful (and apologetic); and told me I should get 25 minutes at full intensity continuous before they overheat. They quickly sent me two replacements; which I received yesterday, but both of these also shut off temporarily after about 10 minutes--and they're definitely hot--too hot to touch. (This is testing on a table in an air conditioned room). Although this is a big improvement from the 3 minutes I got from one of the previous ones; I'm wondering if others who've used these Lume Cubes have gotten more than 10 minutes of continuous use at full intensity, before they start shutting down for about a minute at a time due to overheating?
