F96 T8 retrofit lighting kit is a complete set of components that allow you to convert two lamp 8-foot fixtures to a four lamp T8 configuration. It's an easy retrofit that eliminates the need for long, cumbersome 8-foot lamp to more convenient 4 foot. The electronic ballast is so reliable that they have a 5-year warranty and can operate lamps for much longer. It saves 30 watts simply by converting 8 foot T12 slimline lamps to T8's. Imagine having only one type of fluorescent lamp in use whether it be in an office or warehouse. The brackets on the F96 T8 retrofit kit include the sockets already wired and placed for a quick retrofit and can be adjusted to any channel with a fluorescent lighting fixture. Any licensed electrician should know how to put this together, but someone in the maintenance department could do it as well. The ballast has a five-year warranty, but you should see somewhere around 20 years of product life. You can also choose any color fluorescent you like, so that gives you more flexibility for future changes. All the parts in this kit are industry-standard, and there's nothing that's going to be obsolete. Many utility companies are giving rebates back to commercial customers for retrofitting to 4 foot T8's. Call us if you have any questions about that or anything else regarding this product.
