Lighting

Postby KittyKat » 2006-01-05 20:11

so far i have figured out that most corals need special blue lighting for growth (well... Kev told me)

will ANY blue tube/bulb do? or does it have to be the "proper" type that's sold at the LFS?

would it make any difference? :poke:

As long as it has the right spectrum then it should be fine *runs off to get packaging*

The Actinic lighting wavelengths are about 450mm so look for lighting that has a visible wavelength (spectrum) of 450mm (and is obviously blue)

No don't! Ones from homebase will only "expell" light within the visible spectrum. Corals also need light which is not visible to the human eye, which is what proper aquarium tubes provide.

also a bit of visible spectrum at 550mm.... proper Actinic lighting could be hard to acheive with domestic lighting, I think there are some LFS that sell Coralvue (I think) 9w Actinic lighting which I don't think would be that expensive

Fish stores or online vendors have special blue actnic bulbs pretty cheap, I'm about to order a 20,000 K (x2) for my upcoming project it has color from yellow to blue and a little more I think. I will post updates if it works. Oh yeah they only cost fifteen dollars (US dollars) from my online dealer, don't really know what they cost in pounds or whatnot.

Meh, here in UK things are more expensive... As this post was started well over a year ago, I thing I should update it to say that I have now chosen the lighting I will be using, although I am yet to add water to the reef to be :( But everything should work out well in the long run :)
