LED Gx24q 4-Pin Base Light Bulb, 12W Gx24 PL Retrofit LED Recessed Light Natural White 4000K 26W Compact Fluorescent Lamp Replacement for Ceiling Fixtures, 4-Pack (Remove/Bypass The Ballast)

Excellent fit and function. Exactly what I wanted

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.

I have tried all the four elements in my existing fixture, which had older version of GE LED bulbs. Since the older version of the bulbs were hard to replace, I tried to replace them with these new. All four just "blinked" ONCE and they dont do anything when switched on. I tried in different fixtures, all the same resultWould not recommend unless you know EXACTLY what you are getting into.Unfortunately I could not fix it before the RETURN date as I was traveling out of country due to an emergency.

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.

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.

Even after bypassing the ballast, it wasn’t bright enough AND was flickering. However, the flickering was due to the dimmer switch. I replaced the switch with a standard switch and no more flickering and is much brighter as well.You need to bypassing the ballast and must be in a non dimmer switch. It works great!

Product solves the short lifespan and overpriced fluorescent bulbs in my panasonic ceiling fans- bypassing the ballast is very simple but in my case I left the old ballast in the fixture as it formed one of the walls of the enclosure and dust would otherwise accumulate in the light fixture (its a ceiling fan/light fixture). Bypass is simple: red wires from the sockets to the black (hot) and blue wires to the neutral (white). Also the q-1,2,3 problem is solved as these fit into all types of fixtures. No more trips to home depot buying the wrong socket style.

I bought about 40 of these. Most of them went out within a year. Wouldn’t recommend.
