What have I done to my P7 ?

Only 2 and a bit dies working now............

Was this a DD configuration?

A little more information about your setup would help. How many cells, what type, ect.

That's a bummer!

Did you bump/squash the silicone dome of the P7? You could have broken some bond wires to the dies (dice?).

looks like either it was DOA or to much forward voltage burn up the wire's to the die's, i toasted a P7 myself but you live and learn 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:

Wow! 3.1v is close to H fv territory, nice to know.

Too bad it got busted.

I got 2 P7s in one order from DX. One was 3.1Vf and the other 3.7Vf

The 3.1 drew over 3.4 amps on a single 18650 cell!

Got a spare I bin or got some P7 d bin but they could be J or I bins who know when you buy from DX away for a week from saturday cheers DocD

I burnt out 2 DX P7 running direct drive on 3 C cells. Just like you said, was bright, then after a few seconds, turned purple, then poof! I have a 2 die and 3 die P7, still runs on my 3 C cells, but of course not as bright. These are now my beater lights. This is why I purchase from PhotonFanatic from now on.
