Original Post: Wiring to Convert to LED Shop Lights

rusigx Member

Hello, I have read and read and watched Youtube videos and I can't seem to grasp what to do to convert my shop lights to LED lights and bypass my bad ballast. The shop light has a hot and neutral wire going into the tombstones on one side and a hot and neutral wire coming from them to the ballast. The ballast has a red and blue wire going to the tombstones on the other end of the light. I'd like to rewire the fixture to bypass the ballast and replace the bulbs with LEDs. I also need to make sure I buy the correct LED lights if anyone has any suggestions on those as well. Thanks for your help!

From what you describe it sounds like you have 8' single pin T12 lamps/fixture. You can retrofit these fixtures to use 4' T8 LEDs using a kit like this: and then using four 4' T8 4 pin LEDs like this: Or you can just buy 8' single pin LED lamps like this:

*** Note: the above links are for example only. ***

The big things you want to look for is that they say "ballast bypass" (or similar) and that they are the color you want. 5,000K will be more blue/whiteish while 3,000/3,500K will be more yellowish. Incandescent is about 2,700K.

With the 4 pin lamps, you have to check how they are designed. In some, you feed the hot and neutral on the same side, while in others you feed the hot on one side and neutral on the other. Same side ones will need non-shunted sockets while each end ones use shunted sockets.

Can I change this ceiling light to LED?

This is my basement light, which is not bright enough for the kid. Since I moved this house, I only replaced the brighter light bulb, but have now decided to get a wider and brighter LED light.

I need advise on how to do so.

I attached the pictures of what I have and an Amazon link that I want to replace it with.

This is 4" larger than what I have. Mine is 8" round and it is a 12" round with 1580lm. Currently, I use two light bulbs which are 60 watts each, which is the max watts I can have on that socket — a total of 120 watts bright, 840lm in each bulb.

But the Amazon light says 17W(120W Equivalent) which is about the same as I have, but since it is a LED light, would that be a lot brighter than now?

I mean, I don't expect significant improvement, but at least better than now.

Or how about 2x2 foot square type fixture? Since it is a larger size even with the same LED size inside, I am assuming it covers more area.

My basement is 400 square feet and has three light fixtures on the ceiling.

And installation. I saw my ceiling light has two wires, white and black. But some of the new models at Amazon have three wires, including yellow.

Does it matter that I have to buy two wire light?

Just about any surface mounted ceiling fixture you choose can be used on your existing junction box (or boxes if they are all the same as the one in the photo).

Just a note: The one you have linked is a 4,000K color which is a whiter light. This may look different in color than an incandescent light which is closer to 2,700K.

Original Post: LED and Dimmer

BOB1934 Member

I have a chandelier that holds 12 LED bulbs. There are six at 4 watts plus six at 6 or 7 watts. The total max watts is 66 watts. I have purchased three different LED dimmers. The dimmer portion of the switch burns out. Twice the dimmer part burnt out in about an hour. The other burnt out in 4 or 5 days. The on and off button on the dimmers still work so I am able to turn the lights on and off, but not the dimmer part of the switch. The LED dimmers state they will handle 150 watts. With the dimmers part burnt out, the amp probe only reads less than ½ amp. Now I have no more than 66 watts.

LEDs are strange beasts. I've never had that many individual bulbs on a dimmer but I have a feeling it's due to the actual quantity of them, not the load wattage. When an LED bulb first powers up, it appears as a short to the dimmer for a split second. With that many on a single dimmer, it could be a major startup.

One thing I would try is a Lutron Maestro dimmer. MA/CL is the model number. It ramps the power up slowly at turn on. It may take that excessive start up load.

my light fixture says "fire hazard do not use greater than 60 Watt bulbs," or something like that. Now if I replace a medium base 60-watt incandescent with a 75 watt LED light is that safe or asking for trouble?

I seriously doubt your LED is 75 watts. Look closely at the label. It's probably the equivalent of a 75-watt incandescent but actually uses about 10 watts.
