So im a bit green, excuse the pun but im hearing that LED lights produce no heat??? Is this right? If so this is a major break though considering most busts in the UK come from thermal imaging cameras on helicopters. Why does this not get talked about more???? This is huge!!!! also whats the difference between led and smd? Also, im clueless about lumens, how many is needed for a decent grow?
Cheers for the reply man.....I got some answers here: http://forum.grasscity.com/lighting/1105304-led-thermal-footprint-no-one-talks-about.html
Bergquist offers a family of standard thermally conductive insulated metal substrate (IMS) circuit boards specifically for LED applications which replace conventional FR-4 PCBs. Better thermal management allows more forward current to be applied to the LED, while still maintaining desired die temperatures, LEDs required to achieve the desired light output. With proper thermal management, Power LED lifetimes can be extended considerably. Led downlights
SMD = Surface Mount Design No leads to solder. Don't think an LED panel doesn't have a thermal footprint. They do, but it won't be as "localized" as a bulb. Will look like a "hot plate".
Essentially it puts out much less heat for the amount of light than HPS. Anyway thermal footprint is irrelevant really, it's hot exhaust they normally pick up on IR.
