I am growing under a 215 watt LED light I made my self. 
If you are curious about it I show some of the build at the end of my 25 watt grow as well as some pictures of the closet. My grow area is 24" x 35" with about 6 feet of grow height if needed. The walls are covered with shiny Mylar. I also have a removable side that sits in front of the sliding door on the inside it is just a big piece of card board with Mylar taped to it. It is removed for the picture. A 4" cooling fan blows in for air exchange and a can fan with a carbon filter is used for exhaust through a hole in the top of the closet.
I have my new grow up and going. I put 16 good bag seeds in to germinate Sunday night and by Monday at bed time about a dozen had cracked and sent out a small taproot. I planted 10 into 4" flower pots. Yesterday night 5 had poked through the soil. Today all 10 are up and growing, so I am going to call today Day 1 of the grow. I am planing on culling 4 of them when I transplant in a week or so to 8" flower pots. Where the plants will live out there life.:hubba:
Now I am going to answer the question you've been wondering.
'Why LEDs?'
The new high power LEDs are only slightly less efficient in producing light than HPS, but you can control the color of light being produced. I have designed my setup to produce light close to the PAR light spectrum. I am hoping by doing this to actually give the plant more usuable light than a comparable illumination by HPS. My setup is using about 35 watts per square foot of growing area or about the same watts per square foot as a 400 watt hps used on a 3.5' x 3.5' area.
