Yeah full LED lighting units from aquarium retailers, for the moment, have come to a hault really. Even though the patent that they say is being infringed on is invaled since the patent only talks about a LED light unit that stimulates marine growth. When LED moonlights came out before they made their patent making the same claims, and if something is already marketed without a patent there can be no patent made for that product but thats another subject all together. However, if you are looking for LED lights for your aquarium you could try the new LED bulbs that have been comming out that fit standard sockets. They make ones that screw into mogul socket Metal hallide fixtures and put out a whole lot more light than a standard 250W metal hallide. The only modifications you have to do is hook a plug straight to the socket and bypass any kind of ballist. You can also get these made in any Kelven rating you want. They retail for about $350 each but most LED's will last over 50,000 hours. Just thought I would throw that idea out there.
