Looking For Cheeeep DC to DC Bucker
Low dropout (12-volts to 9.6-10.0 volts). Senseless to pay $8.00 for a twenty watt fixture. No, I do not wish to keep a master power supply on 24/7 Thanks!

Works GREAT until you see the variance in chip specs. Dark day lamp gets turned on. Sun comes out. System voltage goes from perhaps 12.0 volts to 14.6 volts. Tried resistors they render pathetic light when batteries get low. M.a. & heat voltage tuning is the answer. Yotta see what a big battery charger does to LED lifespan. I wish resistors WOULD work.
