Customer Reviews

2 ft. T12 20-Watt Natural Light (5000K) Linear Fluorescent Light Bulb is rated 4.8 out of 5 by 6.
Rated 4 out of 5 by from questionable specifications The website claims 9000 lumins. You could almost cut steel with that. The information on the manufacturers package says 1350 lumins.

Rated 5 out of 5 by from Great Bulb for an off-the-shelf buy Needed full spectrum lighting for a fluorescent set up I was customizing. At 92 CRI and 5000k this fit the bill. Although its T12, this 20 Watt bulb should not be too much of an energy hog vs a comparable 17 Watt T8. Good buy, was sitting on the shelf at my local home depot so I could get lighting immediately. My only gripe was no shop light fixtures in 24" T12 (only 48"). Though, I have now learned to look at the ballast of the fixture your interested in as most can drive T12's and T8's.
