May I also repeat my annual call for the L4 with the selector ring collar
I know it is a tall order, but then again Surefire isn't called the BEST in the industry for nothing. 3 years on and the U2 is still as magical as the day I got it. I'd buy a U2 again immediately without thinking if I didn't already have one. An L4 with ring would be an equal no brainer. It doesn't even need the newfangled LEDs, just a LuxV and that would be enough.
A simpler request that could be taken care of with just a production run would be a HABK E1L and KX1. Or just a simple black KX1, I'll find my own E1e-BK to put it on. The E1e-BK and KL1-BK (4th-gen with Lux3 and TIR optic) are regularly stocked at SupremeCo (AsiaPac distro for Surefire).
A couple of other ideas that I'm just throwing around: smaller sized Kroma, maybe like the A2. I like the A2's size. HABK would be sweet, too. I want a clickie on it. Sorry, I'm just not one of those guys who breaks down doors (I bang on tables though

)
While I'm dreaming, could I have an electroless-nickel KX2 to go with my ultra-rare E2e-Nickel
I'd like to see 18650 support on the U2/Kroma again. I'll understand if there are some business or other concerns that prevent this from becoming a reality, but I'm a flashaholic and I'm speaking from that perspective. I'm not just a collector because all of these lights get used, and many of them look like they've been put through hell (they have). I'm not a 'tactical' user and hope never to have to be, but I'm a day to day user. And I understand that we may not be SF's biggest target market or the drivers behind their innovation, but I like to think that they keep the flashaholics in mind. I BELIEVE 18650 support on the first generation U2's was no accident.. I still believe there are some flashaholics in SF and that they are still watching over us
I'll understand if it's difficult or not possible to fulfill these wishlists. But I like to hope for the best
Oh yeah. Someone once commented that SF lights were not made rechargeable because there was already a series of SF rechargeables. That's OK with me, but I'm wondering if we can kick it up a notch. What would REALLY catch my attention is a Surefire U2 RECHARGEABLE. Dedicated rechargeable if it has to be. Think Surefire L7 with battery pack. Think A123 Systems' new Li-Nanophosphate. Think 15 minutes to full charge - the fastest charging duty light available because someone ALWAYS forgets to recharge a pack. Think safety too, with the intrinsically safe Li chemistry that won't cause a "My flashlight/mp3 player/laptop blew up" on YouTube scandal.
Even more amazing: retrofit to existing U2's. Glue a 18650 into a U2 body and that way it will retrofit onto existing U2's and Kromas. The thing is, it doesn't NEED to be exactly the same size as the U2. Many combinations are possible: a 'standard' sized pack which is U2 sized, or an 'extended run' pack that's longer and make the light L7 sized. If possible, I'd really like charge-in-place capability. The ability to drop the U2 into a dock charger is helpful. Why do I care about charging.. again because I actually use the lights and find myself unloading and charging often and necessarily.
And if you guys really want to up the technological ante and show the market that you mean business and innovation when nobody else has anything comparable: inductive charging. Contactless, hermetically sealed, no seam for potential water/dust ingress. Show the world SF still is the very, VERY best!
