I just tried out a few of these myself, and I was somewhat
dissapointed with their dark, gloomy appearance. Lots of Blue and and
Red, but not enough green for my tastes. Reminds me of a VHO Gro-Lux,
(If such a lamp exists) perhaps with a little more green than the
Gro-Lux. With a name like 'Aquasun', you would expect a high color
rendering. I'm not sure what the CRI is, but I would be surprised if
it's even in the 80s. I decided to go ahead use them, but only in
combination with some Colortone 50s. (the Philips equivalent of a GE
Chroma 50) I am thinking of trying the Penn Plax Ultra Tri-Lux, but only
if the CRI is more pleasing than the Aquasun. Can anyone give me some
feedback on this lamp?
>What kind of lumen output or luminous flux? Lumen maintenance?
George Booth has made lumen measurements of several different lamps;
you should be able to find them at thekrib.com.
