I found a 1200 lumen Cree unit that is wired for 12v external power....for £16.99 on ebay!!!! Needless to say, 2 are on there way to me now
Here is the link
The 3800 units look great but have not seen them with external power yet, though I'm sure that could be solved with a little ingenuity
3100lmn cree xml u2 on 24x7diy.com wired for 12v.
I have 2 fitted to the GS1150 and they are awesome
