C.F.L with Spectrum AND Intensity?

[MitchMc]

Dear Mr. Riddle’

First thanks for the article it was a very interesting read. The topic of light has captivated me for some time, not only is it interesting from a “scientific” basis but is a major expense, in terms of bulbs, ballasts and electricity.

I have two questions

First the following is a link to a page dealing with a compact fluorescent light put out by envirolight. A buddy of mine, who is big into hydroponics, first referred me to it.


Envirolight CFL

I want to verify some of the claims made, but it is much cheaper than other options and seems to have both the spectrum and intensity we are all after.

Second,even though there are differences in spectrum between what it appears corals use, and PAR, would it be fair to say that in terms of a lightmeter a PAR meter is the best option for us semi advanced aquarists

Your thoughts

Mitch

Mitch,

These lamps have created a 'buzz' lately. I've never tried them, but would think their spectral quality is nothing extraordinary and light intensity per watt is about the same as other 'white' fluorescent lamps. General rule of thumb: If a lamp will grow houseplants, it'll probably grow corals as well (with due regard to lamp intensity).

And, yes, a PAR meter is the way to go. Unless you've just won the lottery... then I'd get LiCor's submersible spectroradiometer for a bargain price of $16,000. I'll gladly trade a week in my house's ohana for a few day's use ;-).

Dana:

What is an Ohana?

James,

Ohana - obviously an Hawaiian word and means several things. Ohana could mean "family" and it is sometimes heard in that sense, although it generally means a small, separate house for a family member to live close to relatives. Haolies (like me) most often use "ohana" to mean a place or room for guests. And if they get out of line, we kick 'em in the okole.
