I've got the Nite Ize in my 2D cell as well. I agree it's not as bright, so one day I said "to heck with it", and switched back to the regular bulb. Whenever that one burns out, I'll give in a switch to the LED.

ALSO, I was wondering if anyone else knew the answer, but I bought my 2D Maglite at Target, and it was on clearance at the time for a ridiculous $4-5. Anyone know why this would be. It's a good flashlight but a real ugly "gold/dirt" color. Could this have been the reason for the clearance?
