I wander if anyone can assist me, I have been contracted to replace 10 fittings with T5 fittings with LED tubes. The client requires that all the fittings in the underground parking be kept the same. The original installation consists of 4ft single open channel T5 fittings but I have searched far and wide to find 10 to no avail. They have just converted about 30% of their 200 fittings to LED and want these random 10 which were add-ons to be the same.
