Velleman MK147 Dual White Led Stroboscope

I put these strobe lights and controller on a 450 size 'Air Wolfe' RC Helicopter and what a cool add-on.They are bright enough to be seen clearly in full sunlight and greatly improves twilight visibility.Very clear instructions and if you have any soldering skills at all it is an easy kit to build.

It works like a charm Thank you!

Schöner Bastespaß, auch für Lötanfänger. Die LEDs sind wirklich sehr hell. Preis ist o.k.

simplement expérimenté la chose , fun a construire,simple ,mais attendez vous pas a avoir un effet de ralenti efficace mème en ajoutant des del.

Don't let it's size fool you. (Its about the same height/width as the 9v battery that powers it.) I put this together in about 20 minutes, but my goodness, this strobe light works!! You can adjust it to flash from 1 to 60x a second, although you really won't be able to to see it "flash" much higher than 2/3rd setting. After that, the human eye only sees a solid white light....You'd need a high speed camera to slow down the flashing to be able to see it switch between bulbs at max setting.Assembly is really easy on this one....even for the fairly Spartan directions that all Velleman project kits are known for. I like the fact it has an On/Off switch, so you don't have to remove the battery to turn it off like so many Velleman and other DIY kits make you do. The battery in effect acts as the stand for this.But just as a warning....These LED lights are EXTREMELY bright, and the strobe effect is intense, so if you or someone around you has epilepsy, bad idea to use this. Otherwise, it's a ton of fun!
