T-8 vs. T-12 (Here we go again!)
For a while now, I've been thinking about designing a new hood. I've
currently got two twin-bulb strips, and it's a hassle. So, I dug
into the Grainger catalog to pick out bulbs and ballasts. At first,
everything seemed easy:
CRI Initial Lumens Price
Phillips 5000K Ultralume T-12 85 2925 $10.96
Phillips 5000K TL850 T-8 84 2950 $ 4.64
Gee, that was easy. I *love* T-8s! Ballasts are cheap, too!
Magnetek has a 4 T-8 ballast (B423I120RH) for $41.20. Then I looked
back at the bulb section, and saw...
Phillips 5000K Advantage T-10 80 3700 $10.67
Hmm. CRI isn't quite as good, they're a little more expensive, but a
25% increase in lumens sure sounds good!
Does anyone have experience with the Advantage bulbs? Advice?
