Gx24 4-Pin Base LED Bulb, 12W G24q PL-C Horizontal Recessed Light 26W CFL Lamp Equivalent for Kitchen Light Pendant Lamp Dining Room, Warm White 3000K, 4-Pack (Remove/Bypass The Ballast)

Good LED replacement. Very easy installation if you have some basic electrical understanding since you have to bypass the ballast. Very good and bright light output. No flicker or fllashing.

These bulbs fit the standard socket but you NEED to bypass the ballast. That just cuts the electrical bill further and makes it simpler to replace in the future. Just be sure to mark them in some way. It would be nice if they sent stickers to put on that says that the ballast is no longer needed.

These are great. By passing the ballast of the CFL bulbs was a breeze. once I was able to to get it on the bathroon fan and light fixture.

These fizzle out so fast. Within like 3-4 months, about 4/8 of them burned out. Waste of money.

These are great, BUT, if you are replacing CFL bulbs in a light that has a ballast you MUST know how to do it. Most negative reviews on here, from what I can tell, are because people just plugged them into a CFL socket with a ballast. You MUST bypass/remove ballast if you are using these, otherwise you will get the flickering, only comes on for a second, burns out or melts problems. A socket with a ballast initially gives a high voltage charge (i.e. 600v) to start the CFL bulb. These work off a straight voltage from your line (i.e. 110v). These ARE NOT "plug and play" if you are replacing CFLs that have a ballast. The advantage to getting rid of the ballast is this: ballast may be hard to find and/or fit in your fixture, LEDs consumes less energy, cost for 4 of these bulbs is appx. $30 vs. $80 to replace 4 ballasts, longer life expectancy. If you don't know what any of this means or do not have the knowledge to convert your fixtures, don't buy these unless you are going to have an electrician do the work (cost of that may outweigh savings). These are worth it if you know what you are getting into and can perform the transition. The picture with 3 sconces have been converted to these LED bulbs and ballast bypassed. The picture with 2 sconces above TV are still CFL w/ballast. Will convert them when bulbs or ballasts go bad.

These lights so far have worked great Every bulb I ordered and installed has worked the light spectrum is good they fit a 4 pin can light fixture but you have to get rid of the ballast. exactly what we intended to do. If they work for 5 years they should get 5 stars.

This review is for the Gx24 4-Pin Base LED 3000K replacement compact fluorescent bulb.Reading other reviews, a lot of people that install this product don't know what they are doing- period! This product works great if you do it right. A lot don't. We have installed about 30 at this time and have about 120 to go with no issues.First, remove the old compact fluorescent bulb. Becareful not to crack the bulb socket when removing the old bulb. There is a tool made to remove these bulbs. Amazon does not sell it. It makes it much easier and no chance of cutting your hand. You must remove the old ballast and wire this LED upgrade directly. In other words, cut out the old ballast and throw it away. This works like a champ!Note: I bought the 4000K version and it was too bright so went with the 3000K.

Excellent fit and function. Exactly what I wanted
