Cree 60 Watt LED Driven By Joule Thief Circuit.
This is a 60 watt equiv. LED bulb that uses 9.5 watts when driven by the mains. It is rated at 800 lumens and is the best LED bulb I have tested to date. Skywatcher over on Overunity.com in the Joule Thief topic showed where these could be taken apart in order to remove the driver circuit, and that it could be illuminated from a JT circuit. I am driving it here with my handy box surplus flash circuit JT. Excellent light and I will be making more of these. It is gutted and put back together, not hard to do once you see how it is built. Thanks for watching.
