T8 lamps can be used in place of T12's if the wattage of the lamp and ballast agree, and the lamps start reliably. The T8's being smaller in diameter may be too far away from the metal (ground) for starting well.

I have flo light fixtures in my garage/shop - some older than others. Are T8 and T12 bulbs interchangable in all fixtures, assuming length is correct?

Good idea Joe, does anyone have any theories on extending the life of a fluorescent bulb or ballast by leaving it on for extended periods versus cycling it on/off for intermittent use? I had installed a fluorescent light in my pantry with a door jamb mounted switch so the light turned on/off respective to the door opening/closing. The only problem was that the light bulb would burn out every 4-6 months. I've since replaced the fixture with incandescent lights and the bulbs have lasted over a year without the need for replacement! Of course I can't wait for the price of LED's to drop and will soon go that route thus leaving fluorescent lights "in the dark", ha!

One thing i always do when changing florescent bulbs in an effort to monitor the life of bulbs and ballasts is to write the date on the bulb in marker. Then screw it in so the written side is on top out of sight. Joe Corunna, Canada
