science is meters, seconds, grams not feet, yards or pounds The metric system is an internationally agreed decimalsystem of measurement. "The metric system has been officially sanctioned for use in the United States since 1866, but the US remains the only industrialised country that has not...

Its the material or wavelength here Gan or 450nm.

a change of 10°C results in 2% flux variation Vero 29 25°C(100%) to 35°C(98%) - this change is near linear up to 90°C

there is only one company in the world shipping anything to anyone...CIA

it´s not dumb, i now some machines that work this way. A relais for the main power, all secondary components will be controled by SSR

if we talking about temperature differences then Kelvin is equal to Celsius....no need for transformation it will be higher see here... http://www.aavid.com/thermal-tools/temperature-correct

i have no idea what that means(marked yellow)... >:((:

with a SSR 40A you will run into this problem... Solid State Relay Leakage a solution for the Inrush Current... Special Thermistors Limit Inrush Current

Typically, a vacuum pump is used to remove the air from the empty heat pipe. The heat pipe is partially filled with a working fluid and then sealed. The working fluid mass is chosen so that the heat pipe contains both vapor and liquid over the operating temperature range...

if i looked at the spd of this Prototyp and a professional Light I would say it´s more for pro´s Prototyp 4000K/660nm (all leds running at 1050mA)
