there are some cheap deals on ebay. i'll put a link to the guys i just got my led light for my planted tank. cheap comparatively.
edit: here is a link to something. they have a few other things as well http://www.ebay.com/itm/LED-Aquarium-Light-Nano-Pico-Marine-Reef-Cichlid-11-Clamp-9x-1-Watt-/290652859108?pt=LH_DefaultDomain_0&hash=item43ac42aae4
i just got mine and it is nice well worth the price.
Does it have a remote by chance?
I just found this one: LEDwholesalers Dimmable High Power PAR38 w/ remote. I found the PAR values to be pretty good on that one (>2000 @ 3", 750 @ 1', 242 @ 2', 111 @ 3', and 64 @ 4'), and the ability to adjust the lights separately is a nice touch.
