Darn that Congress, baning mercury-vapor ballasts & bulbs 2005! Why do I have the hassle of replacing a high-up MV fixture when running out of bulbs? Dangerous! Phoning this biz, talking to the specalist, we got an order together that appeared on all counts to successfully work w/o tweaking the fixture ... plugNplay. Arrived well packed pretty fast ... sorry, Charlie - NOT working ..... Began to email my problem Ashley took over 1. we don't have anything that will work anymore - it's been a long time since 2005 2. here's many links to others that have something that works - I know b/c I detailed a match to their bulbs via the specificaitons you gave me (WOW) 3. connecting you to RMA, who is giving you a shipping-FREE label to return in same sleeves, box, packing et al. OLD SCHOOL customer service that INSURES REPEAT, loyal biz
