Why no long running lamps for SF M6?

357 · Nov 22, 2004

Currently, we have a choice of 500 lumens @ 20 minutes or 250 lumens at 60 minutes IIRC.

Why no lower power lamps that run much longer? Like a 125 lumens lamp running 2.5+ hours? Or a 65 lumen lamp running 4+ hours? I think these would be very useful, and allow folks to use a Surefire in non-tactical operations (where runtime is more of a concern).

Its a tactical light. Thats like asking Ferrari to make a 2 Liter replacement engine for times when you want better gas mileage. /ubbthreads/images/graemlins/wink.gif

You could use a KL6. I think a KL2 would work too.

I wonder if any 9V bulb would work... like the N2. Granted the springs may not be the perfect length, that should be okay for "casual" use. The only catch might be that the beam would not be in perfect focus.

Are you sure KL6 works? I can find nothing on the Surefire website about it being compatible.

Assuming it does work, what is the runtime of the KL6 on an M6? That would be an impressive combination....

The KL6 does work on the M6 - I've done it myself. Never tested the runtime though.

It looks like the KL6 will run for about three hours on a M6.

No they will blow they are not designed to work with two sets of batteries in parallel.

Yes, the KL6 can be hosted by an M3, M4, and M6. It will have the same brightness with different runtime. If 357 or any of you are interested in a new KL6 bezel, I have one for sale here:

jbev,

I also thought of running the N2 Lamp Assembly on an M6, but I was told by our fellow forumites that it would not work. Please see the following link:

Yeah, I was thinking about that on the drive home and realized that the equivalent internal resistance of the battery "array" would be half... too much current. /ubbthreads/images/graemlins/banghead.gif

I should know better than that. But I bet it would make a neat flash bulb, granted a very expensive one.
