Review by Bud Herod

I meant to write to you sooner, but being retired I seem to be too busy all the time. Anyway, here in Northern Illinois and Southern Wisconsin your LED tube lights are a definite hit ! ! I just received my order of eight T818W tubes for my garage so I have to get busy and start modifying my fixtures. My first order of four that got bought right out of my hands by the guys up in Wisconsin have them hooked so well that they set up their own account with you for their first order of 12 T8 18W for the aircraft paint room in their hangar and they have me busy modifying all their fixtures as well. Great product, fantastic amount of light, and the CW 5000K light really makes the sprayed parts pop. The old fluorescent tubes made everything look slightly yellow. Thanks again, and I am

Review by Robert J Walt

Just received the bulbs today and had just about all the ballasts removed from fixture. I want to thank you for the great shipping and they all arrived without any damage! SUPER

I also am very impressed with the lights my goodness, I had no idea the brightness and white light, glad I went with the frosted, very nice product at a reasonable cost.

Thanks for sending the diagram for the ballast removal. WENT VERY WELL!

Just wanted to let you know how much I enjoy the LED lights already.
