I’ve a DX light, it was £28 delivered, 900 lumens, 3 modes, 3hrs run time and has lasted 2 years (10-20 uses only though)
Its been fine but gets red hot during use, and the stories about overheating batteries etc scare me enough to not mount it on my helmet. Also this year at SITS the lamp came loose twice from the mounting bracket forcving a mid lap repair or two.
I too want something more trustworthy with a prereq of 2 x SITS laps or 3-4 hours burn time same lumens, without carrying a spare battery – and after my Hope R4 thread last night my conclusion is either:
a) A Hope R4 standard, nearly 4 hours £200
b) Asking Smudge to supply a battery which will get his X2 to 4hrs, and pay the £89 plus whatever to do so which I think will come in less than the R4.
Depends how much light you want – I notice that eighteenbikes have a couple of 300 / 500 lumen lamps on sale for instance.
