Looking for 18650 light with long runtime

Hello BLF,

I bought a Lumapower MRV SE partly because it has a long usable runtime on low.  The details are spelled out in Don's excellent review, here.  What I am looking for is an 18650 light with a longer runtime than the Lumapower clone.  Does such a beast exist for less than, let's say, $30?

Thanks,

raccoon city

I don't think any of my 18650 lights even come close to that. I would question the usefulness of a 16 lumen thrower though, you'd want to diffuse it for a far more useful beam. The RQ thrower from KD has a similar output on low but an even narrower beam. I've not done many tests on it yet.

 

Going by the output figures, a P60 light with the DX 5 mode XP-G R5 dropin in it might do the same on low and would give a much more useful beam to boot. I'll try to remember and test this configuration soon.

 

The numbers from my light tests are always to be found here.

As Don said, any 5 mode 1x18650 would do the trick probably. Pick one you like that have minimum issues from reading the user experiences. Maybe chaning the driver would help also. P60 drop-in's arent that bad to mod afterall.

This is adjustable down to .1A on 1 cell. This might not be lower than mrv's low, though. Mine hasn't arrived yet. My skyray r5's low is only 0.04a.

What's a good way to diffuse the MRV's beam?  It would be nice if there were a snap-on diffuser that would fit on the end of the MRV.  The little research that I did suggests that an empty water jug, scissors/knife, and some duct tape might get the job done.

Someone mentioned a smear of vaseline would do the trick. Well if you dont mind the cheesy factor try a plastic fake ice cube. Smile
