There is plenty of talk about the GE Fresh & Salt bulbs. NO T8 at 48" :cry: Actually they supposedly have one but even their web site denies it! It is (or will be) F32T8/AR/FS #92882.
That said is there any opinion about the Phillips Advantage F32/T8/ADV850. Is affordable, highly efficient and reproduces red and blues well.

Hmmm, when I look at the Phillips Advantage bulb specs, they are actually VERY similar in red/blue spectral output...
Phillips Advantage 850 Watts: 32 Max. lumens: 9700 Rated lumens: 3100 Effic.: 0.32 PAR uE/s: 46.2 PUR Total uE/s: 22.8 PUR Blue uE/s: 11.5 PUR Red uE/s: 7.2 R/B: 0.63 GE Fresh & Salt (AquaRay) Watts: 40 Max. lumens: 10000 Rated lumens: 2350 Effic.: 0.24 PAR uE/s: 42.6 PAReff uE/s/Watt: 1.06 PUR Total uE/s: 23.2 PUR Blue uE/s: 12.4 PUR Red uE/s: 7.6 R/B: 0.62 The GE bulbs seem slightly more intense in favor of Photosynthetic intensity (23.2 vs 22.8) and the Phillips somewhat brighter in terms of human perception (3100 lumens vs 2350). But they're very close, overall, and considering the Phillips bulbs are high efficiency T8's, I'm definitely curious about trying them. Have you found these at Home Depot or Lowe's?

Do they have a lot in stock, or is it scarce like the GE bulbs?

Using Goggle in search of lighting articles I came across this:
http://article.dphnet.com/cat-04/lightcompare.shtml I think it may be posted elsewhere on this site. Nonetheless, the Phillips rated high. The bulb is not a specialty bulb like the fresh/salt but it is designed for office buildings for long tem light output. Tehy came at about the same price about 11.00 a bulb. Phillips lists these sites for the bulbs (w/o special ordering them) Name Phone URL Email Ace Hardware Bulbman-Seattle 206-343-0979 www.bulbman.com Bulbmansea@aol.com Bulbs.com (888) 455-2800 www.bulbs.com Colotex Electric Supply Company (303) 893-0023 doughample@aol.com Crum Electric Supply (307) 266-1278 www.crum.com jbox@crum.com iQVC (800) 367-9444 www.qvc.com webmaster@qvc.com Merchants Paper Co.
