Refugium Light

Anyone have any tips for a cheap refugium light (DIY or not) for a 18x6x14 HOB refugium that won;t bleed light into the display tank?
 
I use a regular 23 watt CFL bulb in a metal clamp-on shop light fixture from Home Depot or Lowe's. The whole thing costs around $10 and I have the fastest growing macroalgae around, hahahaha. I think that would bleed into the display though...
 
Check Melev's site for the sump light he recommends. That works great for me. Also, Sun Lighting on Broadway--near me, incidentally--carries Par 38 LEDs rated 5500K. I'm gonna try one of those next.
 
Let us know how that goes. It seems like 5500K would be too hot for plants - I thought around 3500 was best.
 
PS my jbj nano glos, which are designed for fuges and produce tons of chaeto, are 6500k. I cant speak for plants in general, but I don't believe that chaeto requires low color temps.
 
That's actually really good to know. Maybe chaeto will grow but not nuisance algae. Of course we want nuisance algae on the turf scrubber (and 3500K will do it including grow a ton of chaeto). I also have some chaeto in the display section of my nano for the beasties to live in and I have algae there that I don't want. How's the 5500K with corals? Thanks for the info.
 
Can't say. I don't keep corals under 5500k. Some softies and lps might be fine in the 6000 range but I wouldn't make a practice of it. Also I do see some nuisance algae, mostly film algae, and cyano in my sump if I don't cull it.
 
Coralife makes crew in florecent (spelling?) buld for like $15...they have 50/50 and all daylight...thats what I use with a Lowes or Home Depot light clamp thing

I have cheap/ugly palys and zoas growing just find under it in my fuge (a 23 watt CFL bulb). I thought for sure they'd die, but they've been there for about 4 months, growing and spreading.
