Weird line or break in a Q5

kilgor · May 14, 2008

I've had my Nitecore Defender for 6 months now and it is an outstanding light. Looking at the led, I noticed what appears to be a crack in the led. Performance is still fine. I don't recall seeing this when it was new, but I saw this same line in ernsenada's review of new Romisen. Here's a pic of my light. Do some Cree's come this way? What is it?

BTW, Nitecore through Tadgear.com has agreed to replace the light if I want. :twothumbs

Resize your pic please, or it will be removed.

I don't see any.

Nothing to worry about. Thats just how the led is and does not affect performance! I will admit upon getting my first cree I had this same question.

Those xr-e just look so different

I'm talking about the black, horizontal line near the top of the led.

Ok, I guess it's normal. Thanks!

That line is where the + and - are separated. The small area at the top is positive and the larger area where the die is, is negative. All Cree emitters look this way.

Oh that, I thought you meant a crack on glass dome or something. Well as you already found out, it's normal.

Thanks for the explanation. I love this light and recommend it to anyone wanting a BRIGHT 1AA w/ forward clicky. I'm glad that I don't have to send it in.

It's perfectly normal.

All Cree XR-E LEDs that I've seen have that line.
