I'd like to know if anyone uses the Ultrafire TH-T60 (5 mode) for a Bike light (from DX). I have an MTE SSC P7 (also from DX) with the exact same body but it will dim quite suddenly and I'm not sure how to fix it. I really like the floodyness of the beam for bike riding. So now there is the same body but with an XM-L emmiter and I wanted to know if it had the same problems that my MTE has. If not, I'll get it but if it has the same dimming problem then I'll pass. Or, does anyone have a better suggestion for a Bike light? I really like the single 18650 set up and I don't mind multi modes; and my price range is right around the $40 mark.
