I believe the salt came from splash, I had built an overflow into the back of my aquarium and I'm thinking that's where it came from, I had the same aquarium in my apartment for over a year though with no ill effects. The drywall/gyprock was all puckered etc, it took a couple months of letting it dry out and washing it with fresh water to clean the mess up.
I know the colour would be yellow, oddly enough it looks like 10000k in the store, very blue that's what go my attention. I will try to find a link to it, they looked like they'd be good for aquarium use as they are an out door light, the two light set up was under $100.

 It is only a 5G tank though... But I only paid $30-$40 I think...

I have DIY LED fixture and 10K LED looks loike 14K MH. Nevertheless imo you will still need blue LED or actinics. Corals do much better with 450nm (blue) spectrum. Is this the one you talking about? http://www.homedepot.ca/product/all-...odlight/813283 They say it is"light output equivalent to a 150 watt incandescent bulb and only consumes 30.1 watts of power and lasts up to 22 years." •1900 Lumens •Precision optics and reflector designed to maximize light output. •Maintenance-free LEDs with 35,000 hours of life •5,000 degree color temperature •Eave or wall mount •Attractive bronze die cast metal housing Last edited by RuGlu6; 03-31-2013 at 02:09 AM.

If it's the outdoor type spotlight I think you're referring to, I suspect the LED inside is simply a 30 watt multi-chip array similar to the 10 watt multi-chips I used for my DIY LED build, but a little larger. Here's a photo of the 10 watters.
 The 30 watt multi-chips are available (without the housing of course) for less than $10 on eBay. All you would need is a driver & a housing after that for a DIY solution that wouldn't even cost half of the one linked to at the Home Depot and you could order the colour(s) more suited to a marine tank. If you're not into DIY, then I reckon the ready made spotlight is not a bad option for the price. The housing will be a bit heavy & clunky though.
