im a DYI type, I built an LED Light to put on my LD/ commute bike, Schmidt hub with 4 cree leds (3 watt Each) and wired in a votage doubler for slow speed and all stuck in a suger shaker housing. very very bright I can light up half a football field .

I glued in narrow optics as my final choice for road riding vs trail . lots of online resources for such a project

the commercial LED lights have gotten much better!! though a Tad pricey, My home made search light cost 40.00 in parts. .

On my single speed I have an Inoled 10 with a B&M tire gen , for around town it works just fine.
