Have any of you guys tried these yet? I have a couple 400w halide but i'm thinking of trying the 300w led.

LEDs are no match for halides especially the ones you have, one day they may be equal but that day is not close IMO. I have seen them in operation and can tell you, unless you have a very shallow tank LEDs will not allow you to successfully keep a lot of coral. Your going to hear a lot of hype about how great they are from people who get them, but IMO they are only trying to justify paying for an unproven and very new technology and in time the results will begin to speak for themselves. Use the halides until these new systems start really proving themselves long term that's my advice.

If you could get your hands on the LED's they are putting in street lights you might have something powerful enough to light a portion of the tank(led lights are very narrow) but hard to tell the price and longevity of them.

I agree with the fad thing. The price is crazy , but they say they last. I bought a little 8w submersible thing just to get an idea. What a waste of $20. It doe'nt make a good moonlight in a 10g.

Cree is making some that a lot of people are using in nano reefs. I have an old 12 gallon cube that had compact florescent and have been watching a few threads on that board to see how people are doing long term. Because my main problem with the small enclosed tank was heat and leds put out a lot less. As far as a large tank I don't think so yet.

The heat issue is another factor. In the winter my lights are a blessing. Come summer look out! I've done quite a lot of homework to no avail. It's another one of those things I'd just have to see in person.

Cool. I hace a 2' square fan with a "thermostat" on it that I use when the AC can't keep up. The T5vho's I got recently made a big differance in the heat but I had to adjust timing on it to lessen algae growth.

While i agree there are few prebuilt led fixtures out there that can keep alot of corals at depth. If you diy with the new cree leds it can be done. There are now par tests and people keeping sps and clams under there diy fixtures. The problem with it now is just the cost to build a fixture, if you screw something up and smoke 7 dollar a piece led's those add up very quickly. I researched doing one myself and for my tank was looking at around 1k to do it right with 40 degree optics which is equal to a 250w metal halide at 24 inches depth. So the plan now is to do a small one to experiment with and go ahead with the halides for now because of the cost and potential loss if i would mess something up on it.
