    Default Dim Fluorescents

    I have a 24" dual-bulb fluorescent light in the kitchen. Recently, both bulbs became extremely dim. Because they were relatively new (less than 1 year), I thought the ballast had failed. I matched the T numbers, wattages and other specs to a replacement unit at Home Depot and installed the new ballast, but retaining the original end caps. I also replaced the bulbs, on the "in for a penny, in for a pound" theory. When I repowered the unit, it is just as dim as before. Thinking I had purchased the wrong lumens bulbs, I recently bought the highest lumens I could find (1075) "daylight" 20W bulbs. No change. What have I missed?

    Thank you.

    Irish, did you replace the metal shields and check the ground connection, both are required for full brilliance.

    Was the old ballast electronic or magnetic? The end caps are wired differently for each.

    Also, it's not unusual to find a few bad bulbs in a case, especially the low mercury types.

    Good Luck from Columbiana, Alabama
