Re: need help with my surefire e2d led
Hard to say for sure without any beamshots or seeing the light in person. However, apparently there seems to be similar issues mentioned here with other surefire lights using the TIR optic. There are several reports here of what your describing. I believe what you're experiencing may have to do with the TIR optic not being perfectly alligned, thus creating an inperfect hotspot. If your not happy I suggest returning the light or explaining the situation to surefire and having them fix it.

Wow, 2 different ones with the same issue, from the same store, that's odd. I can only suggest trying another or turn the light over to surefire for them to fix, the latter will take a few weeks though:thumbsdow

Is the led or reflector off kilter? Try taking the head off and put it back on?

The e2dl doesn't use a reflector, and it's a sealed unit so taking the head off won't have any effect.

I think I will use it the way it is I took it outside tonight and it is much less noticeble at longer rage. and it still makes a very good light. thanks very much for the help
Re: need help with my surefire e2d led
It's just out of focus slightly. Sometimes with TIR lights it can be off center.
My LX2 was so off it had a shadow in the hotspot. With a TIR there is basically just a hotspot.
I wrapped the bezel in a rag and put it in a vice and took a channel lock to it to break the loctite. I re focused it to perfection and plan to re loctite it so it wont move. Haven't gotten around to that.

Re: need help with my surefire e2d led
I just bought a KX2 head and took it apart to put a XR-E R2 LED in it. From your description, it sounds like the LED isn't perfectly centered. The way the TIR optic is mounted, it's unlikely the optic is out of alignment.
I reflowed soldered the new LED on the stock board and when I put it back together, the beam was as you describe. The LED board is held to the head with two hex screws and adhesive, so it really seems unlikely that it would move on its own – that is, it sounds like the LED wasn't centered perfectly in manufacturing. I centered the LED and now the hotspot is perfect. With the glue removed from the front part of the head that holds the optic, I was also able to get the best focus. Of course I know I was voiding the warranty as soon as I pointed the heat gun at the head.
I agree with ebow86 – call Surefire and talk to them about it if it bothers you.

Surefire E2D led beam problem
I just bought a Surefire E2D Led Defender. When I turned it on I noticed the beam wasn't a perfectly round circle. I check out some review on youtube and every Surefire E2D Led Defender review had a perfectly round spotlight beam. Should I return my flashlight to Surefire or is this normal?

I'm having the same problem with my defender. The beam isnt a perfect circle. Is this normal?

I don't think that's normal. Sounds like the LED isn't correctly aligned. I'd send it back. :thumbsdow

Should my flashlight have a perfectly round beam?
