Rated 4.4 out of 5 by 35 reviewers.
Rated 5.0 out of 5.0 by better than other instore price didn't take real long to arrive came in good condition so far all bulbs function too early to tell how long they last March 24, 2015
Rated 4.0 out of 5.0 by Nice bright white Other than having 2 dead out of the box the purchase was worthwhile. We needed 6 to replace all of the tubes in our house. We have 2 spare after the issue of two of them being DOA, really expected 4 extra thus the 1 star knock on the quality. Overall worth it, the 6 pack price was comparable to the 10-pack so the extra bulbs helped keep this from being a 3-star. March 3, 2015
Rated 5.0 out of 5.0 by Wow, that is bright. The local glass studio closed and my daughter was left without a place to do stained glass. I have a room in the basement with a workshop in on one side really nothing but junk in a dark corner on the other side. After a lot of cleaning we had a really nice size art studio, but no lights. I picked up 2 of the cheap t8 fixtures and after installing them I relized that I use t12 at the house. Back to Home Depot! I was about to pick up the cheapest 10 pack when I noticed the little chart about color temp right below all the boxes. These were going to be for a glass/air brush studio after all, so I got the Daylight Deluxe. What a difference. On my bench under standard lights I can't tell dark blue from black. Under these I can see everything. Every color and streak in every pane of glass. Fluorescent paint seems really bright. I really like these and plan on borrowing the area from time to time for my own projects. August 29, 2013

Rated 5.0 out of 5.0 by No buzz The light has no buzz. That assumes your light fixture is not more than fine years old. February 5, 2015
