Replace Home Office Fluorescent System with LEDs

What a great & economical solution for replacing a fluorescent lighting system. I have a home office with 4 large fluorescent light fixtures mounted on the ceiling, containing a total of 16 CFL tubes and 8 ballasts. I dreaded the thought of having to remove these large fixtures from the ceiling and buy & install all new replacement fixtures.
After doing some Internet searching, I came across these magnetic LED retrofits. They seemed like an ingenious and simple solution that would allow my old CFL fixture housings to stay in-place. So, I ordered 4 of these 36 watt retrofit kits. Upon arrival, I turned off the circuit breakers, removed all the old CFL wiring and ballasts, as well as the CFL "tombstone" connectors, then snapped the LED magnetic strips to the metal enclosure and reconnected the black & white electrical wires. Flipped on the circuit breaker and wall switch and everything worked! Saved me a ton of money and took about 50 lbs of weight (ballasts & bulbs) off my ceiling.

Flourescent retrofit kit.

I'm very happy with this kit. The magnetic connectors made it especially easy to assemble. I was a little puzzled by the dimmer wires. I don't have a need for a dimmer so I just left the wires as is. I was curious if I should connect them to each other, but I did not and it worked. I really should have bought one that was not dim-able, but I didn't see it.
