what does the word "linear" refer to that makes this different and more expensive than the regular bulb of the same name and description..

Asked by: judy
Linear refers to the shape of the light bulb.

Customer Reviews

4 ft. T8 32-Watt Cool White (4100K) Linear Fluorescent Light Bulb (10-Pack) is rated 3.7 out of 5 by 12.
Rated 5 out of 5 by from Great color and CRI Just installed light fixture SKU 260-349 (UPC 046335942493). This fixture's literature recommends F32T8 4100K lamps with 10,000 hours of life and Color Rendering Index (CRI) of 80 or higher. These bulbs meet or exceed all these recommendations. When we installed these bulbs, we were impressed at the improved light versus the previous bulbs used. Light is whiter and colors appear truer. Highly recommended!

Rated 5 out of 5 by from Nice color and brightness I installed twelve 2-bulb 4-foot T8 fluorescent fixtures in my garage. I love the electronic ballast and T8 bulbs - they light up instantly, even at 25 degrees F, and they never flicker. They take a few minutes to warm up to full brightness in this cold weather, but after that they throw plenty of high-quality light.

Rated 5 out of 5 by from They are brighter than my older bulbs. Of course the old ones were not the same rating, My building is 8+ years old and now that the time came, I changed some, after seen the difference I changed them all to this 4100K.

Rated 5 out of 5 by from Nice upgrade... We just upgraded to these over the other 4' T8 Philips bulb Home Depot carries(Model # 383513, F32T8 TL741 ALTO) -- 150 more lumens from the same amount of watts and significantly higher CRI; 85 vs 78 of the old bulbs. These costs more, but considering how infrequently we change fluorescent tubes, it's definitely worth the money for brighter, better quality light.

Rated 4 out of 5 by from Best value Bulbs last long and easy to install. Best value for the items.

Rated 4 out of 5 by from White light for garage and workspaces Bought these bulbs specifically for using in the garage. They provide a bright white light (4100 Kelvin). I would not use these for indoor living spaces.
