Rated 4 out of 5 by Excellent decision to buy from Home Depot I made an excellent choice when I bought the 4Ft T12 40-Watt Daylight Deluxe (6500K) Linear Fluorescent Light Bulbs (10-Pack) from Home Depot. The service I received by the employees was outstanding. July 29, 2014
Rated 5 out of 5 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
