LED Refugium Light

[maestro]

Is this bulb acceptable to use for lighting a small refugium?

It's par20 narrow flood light, 200 lumens output, 7 watts, 20k hours life, and it outputs virtually no heat.

It emits a fairly bright, focused, narrow beam over the right area without a reflector hood, and without lighting up my whole sump.

I'm just not sure if its frequency is adequate for macroalgae growth...

see if you can spot the kelvin rating or at least if it says cool or warm light, you want cool

Edit: googled it and this is what comes up:
Color: WARM WHITECC Temp / Kelvin: 3000K

thank you! I should be in the 5k-10k range, right?

correct. I think you can find cheaper compact fluorescents that are 6000K and they don't put out that much heat

yeah, but this one looked cooler than the rest :up: I'll look around a bit more

it's for a sump, right? just checking

Where did you purchase this? I'm looking to do the same thing with my fuge.

I purchased it at Walmart. I'm reading

I think you are fine with it. I lit a macro fuge with one Current Powerbrite white led strip (4 x 1 watt LEDs), and it grew macros just great. I used to also think that you needed Kelvin close to natural sunlight (which is 5500K), but all the guys running successful algae turf filters are running bulbs in the 3000K range.

I light my cheato fuge with a 2700K CF bulb.

I wouldn't second guess it right now. Give it a few weeks and see how it works for you. Sounds pretty ideal to me.

Sounds good to me

Yeah, looks good, and the no heat is always nice. I find that even my 26w CFL flood light over my fuge makes a noticeable difference in cabinet temps when it's on vs. when it's off.
