Dirty Harry
I've been an electrician for 40 years. Retired now
Installed all kinds of lights thru the years.
In 2015 I saw a new light in the VW plant in Chattanooga, Tenn. and asked about them. They are called T-5 fluorescent. They were hanging them 21' 6" off the floor. A few months later I saw them turned on. Could not believe some much light out of a two tube fixture at that height.
The next year I installed 12 of them in Coach Mike's new shop. Then I install 20 in a new body shop for a friend.
Next my brother had me to install ten in a new building at his business. A few months later I swap out all 8' fluorescent in one of his shops with the six tube T-5. Lit the place up like daylight! The guys in the other building complains so much that he had me to replace all of 8' T-12 and high bay sodium light with six tube T-5 in their building.
In the last couple of months I've replaced my High Output 8' T-12 with four tube T-5's in my shop.
Twice the light and they use less power!
I'm sold on the T-5.
I'm paying $80 for the four tube and $127 for the six tube with the lamps.
