VERY bright. Bought to put in the back of my parkjets to simulate the afterburner. Simple to power direct from a spare rx channel.Great LED lights i use for eyes on my bumblebee quad :)montati nei riflettori dei buggy scala 1:5 ne aumenta la realisticita e la visibilita nelle ore notturneI purchased eight of these in different colors - red, green white and orange - for lighting a hexacopter. They were certainly bright and the price was great. However, HK has not published any specs for power draw and I didn't think to ask. Running five of these on a single 900mAh. 2S battery took the battery down from 7.4V to 3.18V in 25 minutes (ruining the battery, of course). According to my rough calculations, that means that each of these draws over 200mA per hour. Much more than I might have expected.
I can only fault HK for not publishing the power draw since the product did what it was supposed to and worked well - just not for my application.I use these in my pusher tomcat projects. Best part is they take power straight from your rx. Just plug it in to a spair channel, I usually take the batt channel. These lights are very, very bright. I can still see the burner from about 100 meters away. Awesome product and a very nice price!conso 195ma sous 6v point negatif : s'echauffe vite temp 45c et isolation electrique legere cot ci aurait merit une couche de vernis supplementaire ou une isolation par silicone ?connect to rx for easy source of powerVerry bright!
