Whats the point of LED is they still put out crazy heat?
Well for starters, a crappy LED will put out more heat than a quality one. So I only speak of higher quality LED in this post.
A good LED will put out some heat yeah, but not nearly as much as a HPS that lights the same canopy area. A quality LED will only put out about 60% of the heat that a HPS would (not including IR). HPS puts out like 60% of the energy emitted in the form of infrared (heats up surfaces it hits) where a quality LED puts out zero infrared. This means you need to run the room warmer to get the leaf surface temps for optimal growth rates. So yeah, they make less heat and you need to run warmer. It's a big savings in AC. Plus LED gets better canopy coverage and penetration as it's not a single point source. Light hitting the plant from multiple angles means we get far better penetration and more even light distribution.
The sun puts out about 55% of the light in IR. A HPS puts out about 60% IR. A quality LED puts out about 0% IR.
When we do the math on the cooling costs for a grow using LED we find that setting the thermostat about 5 degrees F warmer combined with the fact the lights are only drawing around 60% of the wattage and combined with the fact IR isn't heating up the room we are saving a lot more on energy for cooling than we saved on just running the light. Add up the savings and it's significant.
There is a place in growing for quality LED lights and HID. You have to do what works best in your situation.
