OLight T15 Problem

I bought a T15 (non-Q5) a few weeks ago. The first two levels were identical in output. Now I know many lights have levels that are hard to tell apart with the naked eye, but this one was identical on the lux meter. Current draw at the battery measured 1.49A on high, and actually 1.50A on the second highest level. So, I sent it back for a replacement, which came in the mail today. This one does the same thing! No difference in the first two levels. High on this one measures 1.12A, and the next level measures exactly the same. I've tried several different NiMH AA batteries.

Here's the readings:
Level 1: (High) 1.12A
Level 2: 1.12A
Level 3: 0.56A
Level 4: 0.30A
Level 5: 0.15A

Has anyone else experienced this? If anyone can post their readings, I'd appreciate it. Thanks.

Yep. :sick2: Apparently using a lithium ion 14500 battery makes the top two levels a little different, but on NiMHs they are the same in output and runtime.

Is the Q5 version of this light the same way? Also if it is will you have this problem if you use Alk or Energizer Litiums?

Thanks

Mine was the Q5 version.

I had the problem with Energizer alkalines, 2000 maH Sanyo Eneloops, 2500 maH Energizer NiMH, and 2650 maH Duracell NiMH.

Fortunately, Matt at BatteryJunction replaced it. Unfortunately the replacement never lit up out of the box. Matt refunded my money.

:thumbsup: to BatteryJunction.

I just tried an Energizer Lithium E2 and a Duracell Alkaline... same thing, no change in brightness between the first two levels.

I also bought mine from Battery Junction. Matt did a great job in getting a replacement to me. Too bad it does the same thing as the first one... I really hate to bug him again.

Does anyone have one that does display a noticeable difference between the two first levels? (On an alkaline or NiMH that is)
