Refugium Lighting

haha, i just kinda wanna see what a cfl led style light looks like

also if you are buying the home depot leds that are 20watts or less. Make sure you look at how many lumens they put out since most will put out less then a 42watt cfl bulb (which is the best option if you wanna grow a bit of stuff and have it be cheap).

Hi Jason

I made 3 of these for the upright frag tank I use to have. The 3 tanks were 24 x 24 x 24 stacked one on top of the other and they worked very well.

If you thing one of these might work for you I have 2 of them sitting here and 1 in use.

I got the 11 inch Coralife T5s at JL at the boxing day sale... if I was to do it again, may go with LEDs as they run a bit cooler...

only had it on since Saturday and i swear i am noticing huge changes already(might all be in my head). Switched out from a 42watt cfl @ 6500k which was not allowing macros to grow and giving my slow cheato/mangrove growth.

it will need some time before i can say anything for sure but the red macro went from little pieces laying on the sand to standing up looking better between saturday and mon.

What size footprint would you say this could comfortably cover at what height above the tank?

It easily covers my 17"x14" and i have about 7" above. would be confident to say at 9-10 off the top you would get in the range of 22-24"x16".

yup, cheato doubled from hardball size to bigger then softball and red macro has gone from little pieces laying on sand looking blackish and flat to standing up red and full looking and visible growth.

only been 5 1/2 days so we will see if this keeps up. Should make it a lot easier to get rid of my few green spots in tank while still being able to feed like a maniac

Works like a charm, attaches on the outside glass of the sump, and works on 4 watts.
