How would you rate the value of the product?
“We have installed them on a couple projects now and have had no problems. I would say that the one sided wiring makes it a little longer installation, do to taking apart the tombstone. As a contractor getting paid to upgrade lighting fixture this style of lamp should be the only style you should go with. ( leaving the old ballast wired in the system is just leaving a problem to come later )”
