the 8' bulbs are all T-12 (12/8's of an inch or 1 1/4" diameter) All T-12s are targeted for phase out, under the original program they should already be gone but the phase out has been extended. Didn't use many 8' bulbs when I was with the county, I have some at Church in the garage and on our sign but they are the single pin on each end, Menard's still carries them. We lost a ballast in one of the garage fixtures and I was able to buy a new 4' fixture for less than the ballast. The new bulbs are T-8 or T-5 (1 inch in diameter or 5/8 of an inch) they have better efficiency or produce more lumens for each watt of energy used. Unfortunately the folks that designed the new bulbs and the bureaucrats that mandated these bad boys don't know squat about people, the new bulbs are more efficient but they also put out less light per tube, so if you do a one for one retrofit the office occupant brands you as the no good %$#*& that's stealing her light AND all these energy programs do is reduce the level of service provided, then you get a Union grievance, seems if you're a member of AFSCME or an elected official the law doesn't apply to you, or in short the facilities guy takes it in the shorts again. Be careful of the LED especially retrofit kits, their efficiency is not as good as the high efficiency T-8's and not much better than the standard T-8. The LEDs are being pushed on us because they're cool and high tech, but if you need a light source of any size the efficiency drops off as you stack 100 LEDs in a fixture. I've used a few LED bulbs for some of the accent and security lights at the church and they seem to be doing well, no complaints and I'm not replacing them twice a year so they might of been worth the $20/bulb they cost. Oh the LEDs last like forever so we'll be laying off the people that change light bulbs and further increasing our unemployment.
