I just picked up this EB2 and found the tint to just be ugly, so I decided to open it up for an emitter swap. Measured about 500lm at 6000K at 70CRI way above the blackbody so it looks green.
Yep, great light, too bad about the emitter... :green:
I did a teardown on an early EB1, I was amazed at the high parts count on the circuit boards for a two mode light:
I've looked inside the head of my EB1 and the electronics are indeed more complex than other small lights from the aspect of parts count and circuit board area. There is a Microchip Technology F24K22 microcontroller with 16K of flash memory as I noted on another thread here. We've literally landed on the moon with less computing power.
The SF 2012 catalog released about a year ago shows the 'programmable' icon by the EB1 but the product box doesn't. If the EB1 is indeed programmable through light shining on the emitter as some of the SF ad copy implies on page 29 of the 2012 catalog, does this mean that the light has some click sequence to put it in program mode? Or, does the light from the dongle generate enough voltage on the emitter to power the programming sequence with the EB1 switch turned off?
Or, did this dongle gadget just not work out and will it quietly disappear from the 2013 catalog?
The EB1 circuit boards have 'test points' that look like they could be used for a firmware update, but this would require disassembly of the light.

I'll have to find my EB1 and see if it has similar circuit boards to the EB2 in your great (and in focus, unlike so many posted on CPF) pictures. My EB1 has an even worse green tint than a recently purchased EB2. I tried to give the EB1 to a neighbor last year during a power outage, unfortunately he gave it back.
I can live with the green EB2 tint I suppose. With some help from the folks here at CPF I've modded a couple of SF U2's and an E1B with newer emitters. But, I think I'll keep the EB2 as it is for now.
The EB2 is a great little pocket rocket for a walk in the country after midnight. Runs fine on a 17670 and puts out a tight spot for seeing wildlife in a field couple of hundred yards away. A little slick in the hand like the other non-knurled SureFire's but a nice size for pocket concealed carry.
