I walked over the Dollar General across the street from work this morning and saw that they had a couple guys up on ladders changing the T8 florescent bulbs in the ceiling light fixtures to T8 LED's. I just looked up the cost of direct replacement of all the T8's with LED's in my business and I'm looking at a 13 month pay back in energy savings. Direct replacements are $7-$8 per bulb vs $2.50 for a new T8 Florescent bulb. Yep no brainer next time I need bulbs I'm going to order a number of the LED's to start re-bulbing my fixtures. When I looked at LED's back in 2011 they were running $35 a bulb not even a consideration over standard T8's.
