I run an electrical crew at a data center with 25 buildings on site. Were in the process of changing lamps out to led when the originals go bad. But we have a lot of issues with anything thats retrofitted failing early. Normally the led fixtures don't have a lot of problems, or at least the indoor ones. It's not uncommon for t5 and t8 retrofit LEDs to have a shorter life that the lamps they replaced and it doesn't seem to matter if they're ballast bypassed or not. LED's use less electricity but so far I haven't seen many that are getting near the life that's advertised.

I would be very interested in isolating the lighting circuits and doing and actual cost per life span test not these things. But were just contracted electrical maintenance so therye not going to turn me loose with ct doughnuts and the equipment to record it.
