GE74472 - GE-240-RS-MV-N T12 Fluorescent Ballast

Works as advertised and is an easy, drop-in replacement for older style magnetic ballasts. I was looking for a ballast rated with FCC Part 18 Class A (Consumer) RF noise specification and this is one of few electronic ballasts that meet that specification, at least at 120 Volts. The fact that this ballast will keep one lamp in a 2-lamp fixture lit if the other fails is a plus - no more changing lamps in the dark. I did test that feature and it did indeed work. This was worth paying a bit more for than the cheaper versions.

Mounting holes for the existing GE ballast I was replacing in a 45 year old fixture were the same as for this new GE ballast. Note, did not come w/ wire nuts. Works fine.

Don't overlook the ballast as being the problem if your fluorescent light fixture is not working. Simple to replace. This is a standard ballast for a 2 light, 4 foot long T12 bulbs. The process is basically the same for all fluorescent light fixtures . Don't be intimidated by all the wires. There are a lot of wires but all are color coded Blue, Yellow, Red, White (common), and black (power). The wire gauge is easy to work with. With the power off to the fixture, remove the bulbs first. Then remove the metal wire cover by freeing it from the slots on the frame. Blue, Red, and Yellow have 2 sets of wires. Remove the wire nuts to free up the wires that comes from the ballast. it is not important which set of the color wires you run the new wires to as long as you keep red to red, blue to blue, yellow to yellow. You will have 8 wires 2 of each color and one common wire (white) and the power (load) black wire.Once all the wires are free, remove the screw that holds the ballast in place and take it down. Take note of the numbers on it and look for a similar replacement. The ballast are much lighter and thinner now . Reverse the process with the new ballast. Push the wires up into fixture and replace the metal cover. If any wires are sticking out from underneath push them gently back in to hide them. For under 20 dollars you have restored your fixture. If you are not comfortable with doing this you should call an electrician or have a friend who is handy do it for you.

Not sure if these are rejects from from production items or what. Installed and it worked for about 2 weeks and quit. I am out of the return window so I loose. They sell this one and Phillips @ local HD cheaper. HD provides returns for their products longer as well.

Excellent product. Easily installs in the old factory position w/o any modification needed. Just carefully, one pair at a time, remove the old wires and replace w/ the new of same color, and voila, your fixture will work like new again. I used a small screwdriver to gently pry out the old wiring from the bulb contacts and then the new wires just push right into place, no splicing or wire nuts needed. This unit replaced one of the old (30yrs) magnetic ballasts.

Not much to complain about with this product. It was reasonably easy to have installed and it works. I'll flip the switch over this product.

The ballast in the 20 year old florescent light fixture in our laundry room went out. Bought this to replace it. The unit itself is smaller than the original, but it fits in the same footprint and has the same attach points. It was very easy to replace and I was happy when the light turned right on after replacement.

1. Simple installation: black to black, white to white, yellow to yellow, red to red, blue to blue. Physically, this ballast is a bit smaller than my existing magnetic ballast, but it still was a bolt-in installation. Converting my first lamp took about 30 minutes -- mostly just to sort things out. I expect that the next installations will go even quicker.2. Very quiet! I absolutely can't hear this ballast at all, and that's a *very* welcome change from the magnetic ballasts.Bottom line, I'm ordering six more to convert all of the lighting in my basement rec room.
