1W vs 3W LED bulbs

I ordered the 120W LED lights from ebay for $250ea. They have 120 little LED lights each 1W. Sadly I was told that the 1W lights are only good for freshwater or ascetic appeal and not for growing corals. I was told the 3W LEDs work well for growing corals. Does anyone have experience with 1W LEDs?
 
It depends all on the power chips (LED) themselves. You could very well be able to maintain corals under the light, given that the 120w of light translates into useable PAR value. There are several local sources that are able to provide you a PAR reading of the fixture. I see no reason you couldn't at the least keep soft corals and zoa/paly corals under that fixture. I had mushrooms and several varieties of palys in a 20l with a single bulb flourescent fixture (the really crappy ones they give you in those walmart starter kit deals...) and the corals seemed to be getting along just fine. Now if you plan to grow light demanding corals like SPS corals, I doubt you will maintain growth and coloration under that fixture, but I could be wrong. Its all in the numbers, and you need to find out what the fixture really is capable of.
