Got them today :twothumbs, new Cree L1 is just a little bit longer than E1L, the new TIR optics is very cool, produces round hot spot and useful sidespill. New E2L is great too, brighter than the old version and with wow, 14 hr runtime, I am so happy I bought both.

Size comparisons with new and old version

Does the new E2L head fit on the older E2L? Will the new E2L light up on the old body?

Nice comparison overview. Love the old vs. new images.

Yes, they are interchangeable and work well, their E2L bodies look same.

Thanks!

I think I may pick up one head.

Chop has had my KL1 head for over a year now. He has been MIA.

What is the exact name given to the new head on the E2L? Is it called a KL1 Cree?

My E2L head is KX2, I think the E1L head should be named KX1, I don't know if they are same?
 
Re: Surefire Cree L1, E2L beamshots and lux readings

I think they are called KX1 now.
 
Re: Surefire Cree L1, E2L beamshots and lux readings

Many thanks for being the first to produce these lux @ 1 meter readings! Any chance you know the drive current of the L1 on high? Or how much it pulls from the battery on high?

I don't have meter to test the current consumption :ohgeez: maybe others get this light later will test it:D .
 
Re: Surefire Cree L1, E2L beamshots and lux readings

Thanks, Chao. Great photos and new/old beamshot comparisons. I am particularly impressed with the amount of spill the L1 Cree seems to have.

The big question for me is still whether the L1 Cree will accept an RCR123A, both as to size for its tube and as to suitability for its circuit. Any chance you know or have tried one?

Thanks again.

Hi, I just tried my new AW R123A, but it can't fits this L1 body :thinking:.

Can the E2L fit any kind of Lithium Rechargeable?

14650-yes:D, and got same lux reading as 2xCR123A
2xAW R123A-yes, but I don't know if this is safe for this new E2L head
AW 17670-no, very tight

I don't think I would try 2 RCR123's. May fry the Cree.
 
Re: Surefire Cree L1, E2L beamshots and lux readings

Is there any chance of an approximate runtime plot for the E2L? I'm really interested to see how long it spends in regulation.

edit: especially on a 14650 or 14670.

Would a slimmer unprotected RCR123A fit (in the L1 Cree)?

I think it should be ok, my unprotected R123As all died and just throw them away last month, sorry, I don't have correct answer.
 
Re: Surefire Cree L1, E2L beamshots and lux readings

Wow!

I really like the more compact size of the L1.
