I purchased and just received a TLE-6EXB from MattK at www.BatteryJunction.com which was my first purchase there and a great experience from the order and follow-up communication to the shipping. Frankly, I can't believe I received it so quickly.
I installed the unit in a 2D maglite hit the switch and it flashed once. I thought, oh no, there was a problem with the regulator, the LED was over driven and blew. Turned it off then on again and reproduced the flash. Checked the cells – 1.36v on each cell. Even though that's just standing voltage, that should be good enough. Nonetheless, I put a fresh set of cells in and presto, the whitest, brightest light I could imagine from this old flashlight. Unfortunately I have little experience to compare the performance to, so take that accolade with a grain of salt.
I know how standing voltage can be insignificant in testing a battery without a load, but I would expect that to play a larger roll in an older lead acid battery, not an alkaline. So, I am now wondering if I received a TLE-6EXA Rather than the B. If not, and it takes over 2.72V to drive this unit, I don't think it can be appropriate for the claimed 2 cell application.
BTW, this is my first performance LED light and my first post here after lurking for a bit and I have enjoyed the passion and technical expertise on this forum. However, I need another technical interest like a whole in the head.
