if this was DD did you get it from DX because i had some P7 info says 3.5 to 3.75 volts J bins, turned out to3.25 to 3.5 volts I bins,
Nail, head, hit ! :twothumbs Sorry no prize (unless you want a half dead P7 ?)
I'm glad I'm not the only one to do this then!
I really wanted to post this so others could learn from my mess up.
In my tightness I purchased said P7 from DX and took their info for the bin as perfect for direct drive on three C cells.
Wow it was bright for a while, well a few minutes and the tint started to go blue..........aarrrrgghhhhhh.
So I powered it up at work on a nice power supply and found the Vf to be around 3.1V, oh, and it's buggered.
Oddly I cranked it up to 3.5 Amps on the power supply and it was fine, whats left of the die workd great. The guys at work were surprised a little LED could put out so much light :naughty:
