I bought four 1w mini star LEDs that I was planning on using under each motor of my disco. Upon testing, the little metal (heat sinks?) piece gets HOT! I think it would melt the arm.
Makes me wonder because I've seen dji quads arms hold this type of led in other posts. I don't know how they prevented it from getting so hot.
Hey fredor - Jaycar Electronics sell LED drivers that will run 4 x 1watt LED off 4/5s flight batteries - damn bright too!!
I bought 1 watt LEDs off e-bay for $4 per pack of 10!!! I used Jaycar mini heatsinks to mount them on as they do get hot.
Happy to provide links to suppliers (and part numbers) if you like
