LED hood for planted FW tank
 
I've built 1 before using 420 5mm LED's, mainly white but some red & blue as well. I came to the conclusion that discretes don't cut the mustard, good but not great. It fits a 30" tank, you can see 1/2 of it in my avatar. It ammounts to about 20W in total.

I've just recieved these beauties today

60W of Luxeon, white, 5600K LED's :)

Now let's see if we can grow plants with these ...... just gotta mount them somehow 1st.

I knew I had some somewhere :wink: here's a couple of bits of likely looking ali to mount them on. Leaning up against the tank they'll eventually end up helping to illuminate. (sorry about the mess :oops: )

Excellent thread DTT - can't wait to see it coming along. :D

Please keep posting pics! Do you have any pics of the set you have already completed?

wow cool led

Daz 01-08-2007 04:59 PM

They look very technical Daveyboy, more pics and info required. Tidy 8)

Thats sweet, where did you get em and how much were they? How do you wire them?

There are several places on EBay selling single LEDS and the ballasts to run them. Dave I'm interested in following this thread myself. Soalris is a commercial unit but costs thousands. I've known several people that bought the kits but failed to assemble them beacuse of how time consuming it was. Youa re right that the luxeon bulbs are currently the best. Look for some of the dioptic magnifiers, they will seriously intensify your LED.

Thanks all. I'll try to take all questions individually.

Kate, good idea, see below.

Cheers joe.

Dazzy, when have you known me to get technical ........ more pics when I've done something to photograph ...... :roll:

Brandon, I got them from a German company called Dotlight, a quick google should find them. They are not cheap. About 9 or 10 dollars each + shipping. Not entirely sure how I'll wire them yet, more than likely 2 sets of 7 in series as I have a top notch 24V power supply to hand.

mike, I don't like to give it a downer for performance as I've not tried 1 but I think the Solaris is ugly !! looks like some1 left an 80's video player on top of a tank !!! for the money it should look better. Having said that I'd love to have a play with 1. I also think their control system is far superior to anything I'm likely to come up with though I'm sure this adds greatly to the cost & isn't something most people would use much.

Anyway as I darn't go against the youpster's wishes here's some shots of the mkI

I started off with 160 white & 80 blue, 5mm, 15,000 mfd, 40 degree, discrete LED's. They are mounted in 2 lengths of inverted white plastic gutter.

Not so bright with the lights on

From the back, covers off

http://i117.photobucket.com/albums/o...06tanks010.jpg

On the tank covers off. Incidentally the covers are 2 black, inverted, similar section, lengths of gutter that sit on top of the white 1's. I would point out that this is not a show tank ..... more an experimental 1. mrst would not allow gutter in the front room :squint:

I wasn't happy with the intensity or the colour so added 60 more whites and 20 reds to bring the total to 420. It works and the plants grow pretty vigorously but it doesn't challenge the 72W of T5's that were on the tank previously. Hence the Luxeons.

Dave, thanks for sharing this, you've made a really professional looking job of it.

Aye, that is some serious lighting you have there. :thumbsup:

davethetester 01-09-2007 04:58 PM

Kate, you are too kind, it looks better in the pics.

Here's a recent 1 of Nugget my female golden ancistrus basking in the LED's.
