Well it was directly out of my hydro guys mouth who's building them. I asked why they cost so much and his answer was the leds. I tried to find some places that sell the LED's 2w or 3w but cant so i only have to go on what he said.

Now that i'm looking more into it, im finding LEDs that cost a buckets load that have high lumen output. NOT YOUR STANDARD LED that cost 2 bucks.
