Can't work out how to link prevous thread but in nano tank forum under "any suggestions" I have a couple of shots of the costco light . It's a four bar 27 watt and looks nice !!

Managed to link photo's . Cost about $19.00................Dave.

A reminder to those who only want to criticise

, I am reporting what I found, and am happy with. As to "proper spectrum". Please tell people that is your OPINION, not necessarily FACT

You are happy with it? How long has it been setup?

You still haven't answered what color spectrum those are, it would be helpfull for those reading this post and considering those lights to know what the spectrum of the bulbs is.

looks pretty low, around 6k

The LOA quad is 6500k. I'm considering adding it to my nano but I'm wondering if it will look too yellow.Since I would be adding to one 10000k PC I'm thinking the combo would be ok. BTW I've read that coral growth is best at this spectrum,that is 6500k.So are the LOA lights yellow from anyone using them?

I was under the impression that the proper spectrum was around the 6k region, the colour temp closest to the sun? And that we only use higher K bulbs because they are more visuallly appealing, but dont offer the same amount of growth as 6k bulbs?

Different wavelenths of light penetrate the water more/better. So as you go deeper, only certain wavelengths are present, or in high concentrations. So corals are not exposed to 6K sunlight, they get "filtered" light, with higher concentrations of blue light because it penetrates the water better.

So higher K lamps are used for coral growth, and visual appeal. Different corals, depending on where in the reef they are, will "want" different spectrums of light. They can also adapt though, and change out the symbiotic *cant remember name* and get food from different spectrums of light.

That is a pretty good impression. Sunlight at noon at the equator is 6400K, so I believe daylight bulbs are around 6500K.
