I love the diffuser we recently purchased directly from Surefire. We go on long walks at night, and with the diffuser attached, the UB3T will light up the path in front of you simular to the Surefire saint on the lower settings. We also have found another great use for the UB3T. Now with the shorter days, we have to take our Whippet and IG to the soccer field for their run. The field is very dark with an artificial turf. Without the diffuser we can find our hounds at ease. We also discovered another great feature. It will charge on the high setting, a glow at night chuck-it ball in a matter of seconds verses minutes with an ordinary light. One thing we have noticed that does not happen with our other surefire lights is when the batteries run low the light flickers which is quite obnoxious even if you twist the UB3T to its lowest setting. On our other surefire's they usually operate with usable light output until the light can't be activated al all. After over a month of use we are on our second set of batteries. We both feel that the ring settings should be Off, then the lowest setting up to the highest oupiut setting. Then Strobe and SOS after that. It would be nice for to be able to activate the Strobe on any setting with multiple quick pushes on the tail switch. If you wanted to disorient an attacker in the dark it makes no sense to fumble with the selector ring for the strobe activation.
I sure hope Surefire will still make available the diffuser (in black) in the future. It makes for tremendous flexibililty using the UB3T in practical night illumination situations.
