DX ligths all day (night) long. I got a 1200 Lumens one last year now everyone I ride with has one. About £20 posted and couple of 18650 batteries and charger. They sell mounts as well.
I have a joystick and its a great bit of kit, but next to a DX its underpowered and over price. Still love it though.
I notice they now have a 4300 Lumen one. Its about £50, takes 2 batteries so longer and would probably be to much (top setting on mine is to much if there is a bit of mist in the air), but I soooo want it.
If you do go DX, there are loads that are very similiar, I recommend the one with the dimpled reflector. We got these (probably over 20 of them now)
