    I had to replace a shoplight fixture in the basement. Got a T8 version instead of the old T12 standard. I never paid any attention to T8s before but they seem to have definite advantages. 20% less energy use, slightly more (though mostly unnoticeable) light output, slower light output decrease, smaller size. Didn't really pay attention to the pricing but I don't know why they would (if they do) cost more.

    I'll be replacing all my T12 fixtures with T8s when they die. That will probably only take another 10-20 years!

    I'm switching my shop over to T8's. The old lighting was 100w incandescents, so it is a huge step up in light output. The main shop is two bays, 30'x30' overall, with two big roll up doors. I'm hanging the lights 10' off the floor and I'm putting in three across each ten foot segment. All the lights are cold start with wire cages to protect the tubes. I'm able to use all the old wiring so that is making the project really easy and fast.

    BTW:
    The 'T' # is just the diameter of the bult expressed in 1/8"

    So a T8 bulb is just 8/8th of an inch (yes, that's 1 inch) in diameter.
    A T12 is 12/8th".
    T5 is 5/8" etc.

    I put a couple of 4-bulb fixtures (T5's, not T8's, 6000K color temperature) in my garage. They are awesome. Now I can actually see myself cutting things 1/4" too short. :supergrin:

    It would be a stretch to claim that T5's are to T8's what T8's were to T12's.

    Depending on application, T8's can outperform T-5's. My research indicated this would be the case in my shop with the lower average temps over a year. Factor in faster starting and warm-up and T8's are higher performance in my shop.


    Here is a good link with some in-depth information comparing T-12, T8 and T5 lighting. http://www.lrc.rpi.edu/programs/nlpip/lightingAnswers/lat5/abstract.asp

    I recently had to replace the ballasts in my parents' 40 year old (4) T12 kitchen fixture. It was way simpler than trying to switch the whole fixture to something newer. We did go with electronic ballasts and they're completely happy now. The tubes fire up instantly compared to the old, magnetic ballasts.

    T5HO or Power Compacts are the way to go now, though LEDs are the future. Then again, most of my lights are for my aquariums....
