2-Pack 6W LED GX23 PL Lamp GX23d 2-Pin Base 13W CFL/Compact Fluorescent Lamp Replacement 120V Single Tube LED PL Horizontal Recessed Bulbs (Remove/Bypass The Ballast) (Daylight)

I had a trouble light where the bulb kept flickering and finally would not light up at all. It never worked well in the garage in cold weather and I was considering just trashing it rather than re-lamping it. I started looking for replacement bulbs and saw that there are now many LED alternatives for the GX23 bulb it uses. I chose this one based on pricing, brightness, color temperature and user reviews. Installation was easy -- I removed the screws holding the lamp's handle together and immediately spotted the ballast (looks like a transformer), which was the only component other than a switch and an accessory outlet. Since the ballast only had two wires, I simply cut them, removed the ballast and then stripped and twisted the two wires that had been attached to it and added a small wire nut to hold and insulate them. The entire process, including disassembly and reassembly took about 15 minutes. The ballast was quite heavy, so with it gone, the lamp is now quite a bit lighter, which I like. The bulb is at least as bright as the fluorescent bulb that it replaced and the built-in reflective lens means that I can also toss the foil reflector and rubber band that held it behind the bulb but also blocked part of the bulb's output. On top of all that, I now have a spare bulb that I will probably never use since LEDs last so long. Would love to have been able to buy just one bulb, but for under $15 it's like having a new and much better trouble lamp, so I still consider it a win.

Great product

I bought these LEDs to put in my drop lights. These led bulbs are far brighter than the CFL s they replaced and so far not nearly as fragile. This may not be true for all applications but, both of the drop lights I have needed some modifications. One needed the socket shaved off where the raised angular bumps on the LED snap into the socket. Used a dremil for that one. The other light the bulb mounted with no problems but the bulb stabilizer wouldn't accept the increased thickness of the new bulb. Again I used the dremil to open up the slot a little. I realize it seems like a lot to do to make this bulb work but, I didn't want to be buying CFLs every time I dropped my drop light.... lol You also need to remove or bypass the ballast in your light if equipped. Not at all difficult. You also need to be aware of the way you install the led into the socket. The wires need to be going to the correct terminals. There is a diagram for this but it is vary hard to determine the pole where the black and white wires go. Looking at the diagram notice that you are looking at the smooth face of the LED not the heat sink on the back of the LED.

These came in a 2 pack which was perfect for my needs. They are nice and bright, and work well. One thing to note- If your lamp is original with a fluorescent G23 style bulb, you WILL have to remove the ballast (not hard with very basic electrical skills) in order to use these.

Exact replacement for fluorescent tube bulbs but you must bypass electronic/transformer board and connect the led bulb to the120 volt supply.

I grew tired of replacing the florescent bulb in my ceiling fan, so decided to go with a pair of these. Taking the light module out of the fan was easy, and cutting the wires to bypass the transformer took just about 5 minutes. The new bulbs just BARELY fit. Another mm longer and it would not have worked. I originally had 2 bulbs in the fan, but the new bulbs are so bright, I decided to leave only 1 in. The color temperature is perfect for me, not too far off the 2700K bulb on my bathroom mirror.

When my very old Ott Lite desk lamp stopped working, my first thought was to replace the bulb. But then I discovered the OEM bulb cost more than I paid for the lamp! I then tried a generic bulb, but that did not work. Ott says there are two kinds of ballast and you have to get the right bulb for the ballast. But maybe the ballast was bad? This LED replacement was a surer and cheaper solution because it does not use the ballast. I just had to snip the two wires going in and out of the ballast, then connect them together before plugging in the LED lamp. The color temperature spec is slightly different, but it looks the same to me, as does the brightness. A good replacement! I just wish they sold single bulbs.

Both bulbs died within 10 minutes! First one in about 7-8 minutes and the other one started flickering a minute later and went out. I tried turning it on and off and the first was completely dead and the other one would turn on for a few seconds and dim out, turn on and dim out. Waste of time and money.
