Question 1

Has anyone else had the problem where the batteries drain even when it's off? I've had these for about three years now and this just started happening

Accepted Answer

Yup, I have that problem with similar lights I bought at Costco. I just put the battery holder in backwards when I'm not using them. No more battery drain. A bit of an inconvenience, but it's worth it not to find the batteries dead all the time.

Question 2

do you know diameter? need mount for my bike and it goes up to 22 mm diameter

Accepted Answer

Hello Mike, I measured the light and it is 29.2 mm diameter in the handgrip area and flares out at the front around the reflector to 34.3 mm.  I hope this helps.  Richard

Question 3

at 100% output how long does the batteries last??

Accepted Answer

Hard to say exactly.  I use mine very intermittently. That is, I use use for between 30 seconds to 5 minutes at a time.  I have been exceptionally pleased with the battery life given what I paid for the 3 flashlights and the level of illumination.  If I had to guess - I would say you get about 2 hours on hi.  Once again, that is a guess because I use mine for very brief spurts.  I do get a lot of spurts though.

Question 4

Is this the same model that costco sold marked techlite lumen master?  great light and would like to buy more.

Accepted Answer

It is. I also had the one from Costco. This is the same exact brand and model. Only difference is this is brighter. The old Costco one was 200 lumens. This is 250. But everything else is the same even the way the tail cap switch works.
