SureFire KL1 head adapter.

I don't know what max Vin is for the KL1 but I ran it on 3 123's with no apparent damage. I assume there is a voltage drop with the load but how much, I didn't check. Perhaps Toilet Pig can provide these specs or one of these days, PK should be back from his world travels and perhaps he will enlighten us.....
Because of the Vin range of the KL1, it will likely be hosted by all kinds of power paks and the true range of supply voltage will be very useful information.

I'm eagerly awaiting delivery of my KL3 so I can see if it will run adequately in a 9P + A19 body with 2 @ 4/5 A NiMH's + 1 @ A NiMH at 3.6 V. These 3 batteries are equal in length and circumference to 4 CR123's (136mm total). I've seen no comment as to whether the KL3 performs well below the 4.8 V input of the B65.
I expect to run the KL3 with 3@ CR123's for the reported 25% increase in luminoscity. My KL1 will probably sit on top of one of my 3 Scorpions most of the time.

Don:
Al has reported that the KL3 works well with the 4.8 V B65. Do you think the B65 drives the KL3 out of regulation?
By out of regulation, do you envision the possibility that 4.5 V, for example, could drive the KL3 to a dangerously high current level?
Alternatively, are you suggesting that the KL3's absence of step-up circuity is likely to make the unit dim at any voltage below the forward voltage of the Luxeon which could be anywhere between 2.9 V and 3.9 volts?

Lemlux,
I haven't seen or played with the KL3 so my statement was based solely on the specs as I have heard them. I defer to Al's statement as he has had some hands on experience. It would be very helpful to know just what the realistic Vin ranges are on the KLx series. I have the advantage of having a pretty good regulated power supply where I can vary the Vin and observe the resultant current drawn. I have no idea how or when the KLx drop out of constant current mode. I have tried to stay within the specs that have been provided by the mfgs as I assume there is good reason for these specs. I have not had call to push the limits to accomodate a particular battery combo that I want to use. I haven't stepped over to the use of rechargeables yet as I don't run any of the lights that often to feel the need. Additionally, since I don't run the lights that often, I don't like the discharge rate of the NiMH. I prefer having 123's in there so I know if I grab a light, it will work. I am looking forward to the day of Li-Ion

Don:
I understand. My questions reflect my insatiable curiosity, not an intent to badger. Your comments about a 2 * Cr123 minimum for the KL3 are consistent with what I've read until Al's post made me wonder what the real minimum is.
I'm not likely to carry a SF 12P sized rechargeable LED package very often, even if it works. I just like to know what I can and can't do.
