Changing the PowerBrite Bulb
The 4-watt fluorescent bulb in your PowerBrite PB9 and Pro7 is rated to deliver approximately 3,000 hours of operation. That’s a long time, to be sure, but there will probably come a time when you’ll need to replace it. The good news is that the bulb itself is readily available at most hardware stores and electrical supply houses—the type number is “F4T5CW”—and you can replace it yourself in less than a minute with just a small flat-head screwdriver (a jeweler’s screwdriver is ideal).
Begin by unplugging your PB9 or Pro7 and then unplug all devices connected to the rear and/or front panel outlets. Then remove the PowerBrite from your rack and use both fingers to press gently on the two “Push” squares on the slide-out drawer so that it extends out towards you. With the drawer extended, turn the PowerBrite upside down. The illustration below shows how to remove the clear plastic diamond lens at the bottom of the drawer: Gently pull back on one of the retaining tabs with your finger and insert the flat-head screwdriver under the clear plastic diamond lens to pry it up and out. Then pull back on the other retaining tab with your finger and remove the lens.
The bulb is now easily removed by giving it a half-turn so that its end terminals line up with the holder slots.
Follow the same procedure to insert a new bulb, then replace the clear plastic diamond lens by pulling gently back on both retaining tabs.
