Ridge Ryder 12" LED Driving Light Bar 60W are on clearance and you get the extra 30% off for the club members taking the price down to $20.30. Works out really cheap these have been sitting at $70 for ages. Stock these should perform great compared to the smaller 3 and 5w LED light bars.
This light bar uses 6 Cree XML2s @ 10 watts each, you can easily enough reflow most 5050 size led onto the PCB. You can find the XML2 in NW or even WW should only cost a around $4-5 each.If you wanted extra power you could reflow the 3v XHP50.2 the electronics might need some modding. If you want to change the tint and keep the same LEDs you can dedome the XML2 and it will give it a more NW tint.
(I am modding one using the XHP50.2 and slicing the domes for a better tint)
