I liked the fast shipping from Revain. Replacing the ballast was very easy. Trim 8 color coded wires, replace the faulty ballast with new ballast, strip the insulation to expose the wires and then connect the wires to Revain's cable connectors - it was as easy as it gets. The installation of T8 bulbs completed the work. repair before powering on and testing. There is now enough light to push the plastic "bulb cover" back into place. Cleaning and installing some hand tools completes another successful DIY project!
