12.00 Volts to 10.00 Volts LED Bucker
Never a dull moment. Genuine 10 watt LED chips (they need a heatsink) are not 12.00 volts capable. Driven much higher than 10.00 volts, light output stays the same but heat increases as dramaticall...

I really don't think these chip manufacturers have their act together as far as knowing what their chips consume. They are after the "12 volt market" with a design that demands 10 volts. At 10 volts, I personally cannot discern much if any lessening of brightness, but amperage (watts) above 10 volts skyrockets.
I tried a competitor, Bridgelux, at six dollars a pop and at 600% of the cost of the run of the mill chip I was sorely disappointed to see very little if any perceptible lumen difference at the same I. Increasing I resulted in heat not more lumens just like with the cheap spread.
As compared to a 5050smd plate the single 10 watt chip just blows the plate away as far as brightness and whiteness is concerned. Very much like comparing the difference between a 7 watt incandescent night light, versus a 10 watt compact spiral. I'm talking about differentials, perspective not actual light output.
What is needed in the RV industry is an authentic LED lamp. Not a conversion. Base made of black anodized aluminum, finned, special diffuser plastic lens to minimize loss of lumens and spread the area of lighting.
Rural families use their car battery and 50 watt 12-volt light bulb. They go to bed with the chickens. If heat is tolerable they may fire off a Flameneta gas lantern to cook by. Expensive to operate, a humidity producer and shoveling more coal onto sweltering temperatures. A ten watt fixture will buy them some extra hours. One sixth the amp hour consumption of an incandescent bulb never mind savings in AWG reduction needed.
Pilas, small batteries down here can cost two dollars each. Ouch! The bread winner uses the car the battery will recharge. It's an absolutely imperfect, carnival of compromises but I've yet to come up with a more cost effective solution. A neighbor just purchased an LTH ciclo profundo bateria for his lancha and it cost eqvt 148 dollars. Please don't ask about solar voltaic. A panel that costs 100 dollars in the states costs 300+ dollars down here. Oh yeah, forgot about the 70 dollar shipping charge.
