Home Depot LED Spots
 

I was at home depot today and noticed they have 150w LED spot lights, 5850k and 150w (think 15000 lumens).... What do you think for a reef?

I had a lovely 60 gallon cube but the salt started to seep into the walls at my home and it was making the gyprock bubble. The g/f said it's got to to and it did. Now I'm moving into a new place and I'm going to try to go back to a reef tank, I have a small tank already, 24x18x14t but I also have a 3 foot 60 gallon. I have a 250w HQI but was wondering if it would be worth selling the light and going LED and using the smaller tank. The light fixture is available in a double unit as well.... thoughts?

I couldn't find a lighting forum to ask so thought I'd drop it in here,

Thanks for any input.

The spots sound ok, I guess the best way to find out if they work is to try them out.
Not sure how you got salt in your walls as evaporation is usually just water and the salt stays in the tank.

I think it will have too much yellow (low K), will need some blue runners to compensate IMHO.

Do you have an online link to this bulb by any chance? That could be a great Refugium bulb.

How did the salt seep into your walls? Did you frequently spill water on them? Anything below 10000Kelvin is pretty yellow looking. It will grow stuff in a reef but probably won't look very attractive.

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.

I've been trying out some LED's I got from IKea....so far so good:biggrin:

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

you are correct 5000K will look slightly cooler with LED then with 5000K MH.
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?

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

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.
