    T12 florescents are being phased out

    You may already know this, but I just found out recently (I'm always the last to get the word).

    T12 florescents are being phased out. Bulb production is supposed to cease in July 2012. So if you're adding florescents to your shop, use T8s (or, at least not T12s).

    It's news to me, too. I've got four cheap 2-tube T12 fixtures hanging in my shop. As they die, I guess I'll replace the ballasts and tubes with T8s.

    I've got a mixture of t-12's and t-8's. The t-12's seem to last substantially longer than the t-8's. I wish folks would leave me and my light bulbs alone.

    I was thinking the other day. I have 2 garage door openers that use 60 watt light bulbs. They stay on for 1 minute after the door is opened or closed. I've never changed one I've been in the house for 19 years and they were put in 7 years before I bought the house. Figuring that the doors are opened and closed an average of 6 times a day that means the bulbs are lit for 2190 hours per year. 26 years =56940 hours of illumination That's gotta be some kind of record.

    I think this is the record bulb Bob. 100 years and still going.

    Vaughn, from what I am seeing around here, it would be cheaper to change out the whole fixture vs swapping the guts.
    If you don't take pride in your work, life get's pretty boring.

    Rule of thumb is if you donít know what tool to buy next, then you probably donít need it yet.

    Uh, Bob......that works out to 6 hours per day, not 6 minutes. But my guess is that the light is on for 4-5 minutes per open and close, allowing time to get into and out of the car, unload car, then close door. So pick the 5 minutes per episode. 5 time 6 episodes per day = 30 min. per day. times 365 days = 1050 minutes per year. divide by 60 = 182.5 hours per year. times 26 years = 4745 hours. I'll let you figure up how much it cost you to run that bulb for that many hours. Sorry. That said, I've got a single 100 watt CFL in my garage door opener. Jim.

    Lets see....I'm not great with math. I went to school to be a mechanical engineer and lasted 3 months before i figured out that good math skills were necessary then went into sales.

    The lights stay on 1 minute. each door is opened and closed 6 times per day, so that's 6 minutes per door or 12 minutes a day that the light is on. 12 x 365 = 4380 minutes per year x 26 years = more minutes that I can do in my head. Did I screw up my math again

    I have had several T8 electronic ballasts fail in the first year.
    And on these they weren't replaceable.. I do really like the little 2 bulb T8 fixtures I bough in general but haven't found them again to replace with like looking units..

    I did find some cold weather rated T8 fixtures last year. I put some 'daylight' bulbs in them and couldn't be happier. Takes a little time for them to come up to full power, but when they are running they work great. The old t12 I had would buzz and flicker like crazy, but these are quiet and just seem to work.

    If they use less 'lectrics' that's great, but the fact that they work better is what I really like.

    Thanks for the heads up Mike
    and like Brent mentioned, the 'daylight' bulbs make a world of difference! I still have one fixture using the 'cool white' bulbs and next to the others, it casts an 'almost yellow' hue.
