Installing the Diffuser
Position the ladder under the the fluorescent light that will be changed out.
Use a screwdriver to remove the old diffuser from the fixture. Most fluorescent fixtures come with factory installed acrylic diffusers that are not very attractive.
Snap in the new diffuser or use the screwdriver to secure it to the fluorescent fixture. Depending on the fixture, there may be screws to secure the diffuser and a screwdriver may be needed.
Enjoy your new decorative fluorescent fixture complete with a new diffuser.
