the average MCD of your typical LED is about 2-5k
anticipated response:
"thats bs LEDs dont get hot to the touch"
OHRLY? Then explain why they use massive (2-3x bigger then the led) heatsinks to keep them from cooking themselves?
You cant simply plug them into the wall and expect them to work.
Correct me if I'm wrong but isnt the whole purpose of leds to reduce overall cost? Having to buy a shitload of wire, fabricate some sort of custom housing, a power supply that can deliver the proper voltage and amperage, and hundreds (if not thousands) of leds is not what I'd call cheap.

You don't have a clue what you're talking about. Its ok, I hear it on every forum. You're not the first person who has no idea or rather the wrong idea about LEDs.
You say the avg LED is 2-5k MCD... Mine are 140k MCD, each.
You think they're hot? They produce a tiny amount of heat, but barely. My leaves grow right up to and around them, and there's no damage; however, leaves that grow smooshed up against LEDs will develop oddly... some parts grow real fast and distort the leaf. But they all end up normal...
Can't just plug LEDs into the wall. No shit? Really? That has got to be the weakest thing I've heard in a while... God forbid you might actually have to do something or learn something... Don't worry, because stupid and lazy people can still use HIDs after all the rest of us are using LEDs...
ThatGuyOverThere- Are you a republican? Because you say "Correct me if I'm wrong but isnt the whole purpose of leds to reduce overall cost?" But then just look at the initial cost. If you consider how long LEDs last, compare to MH/HPS bulbs... plus the operating costs... over time, LEDs blow HIDs out of the water.
The LEDs I'm using initially cost me $.70/watt ($.90/watt if you include the power supply) and running my 25watt tote cost me $2/month in electricity running 24/7.... Flowering is only $1/month.... If I spend the time and fully train the plant, I'll get 2oz out of it. I'll spend 4 months and $5 growing my tiny little 2oz/tote... For you mega growers, that may be peanuts, but for me, a 2oz harvest every month is perfect.
You are right about the 5watt star LEDs being hot, they are. And they also aren't what I'd use to grow with....
This is how I grow...
