Mine had the factory batteries fitted when I got it. Switched it on: nothing. Put in some high capacity hybrid rechargeables: very bright light. Left it in drawer. Went to use it 2 weeks later: nothing. Recharged batteries and switched them to Mars 3.0. Left it in drawer. Went to use it 2 weeks later: bright light.
Repeated the experiment with another set of batteries - the 4.0 was definitely a dud, but surplus to requirements.
Obviously I've done the silicone grease thing on the Smart light. Damo showed me the low-power setting on the new 1W version which cuts the big light, but leaves the 2 lesser LEDs working: an excellent solution for group riding. I'll buy one if the Mars 3.0 dies - it's my 'group riding' light, but with a strip of red electrical tape diffusing the LEDs. I use the Smart 1/2W for solo daytime training rides these days. Feel free to accuse me of cycling-based paranoia.
