Bonlux 2-Pack 6W LED PL Retrofit Lamp G23 2-Pin Base 13W CFL/Compact Fluorescent Lamp Replacement 180 Degree Beam Angle LED PL Horizontal Recessed G23 Bulb Daylight 6000k (Remove/Bypass The Ballast)

I purchased this LED Bulb to upgrade my OttLite PL7972 Desk Lamp/Magnifying Lens from a 13W G23 base fluorescent bulb to a LED bulb. This was easy to do but it does require you bypass the fluorescent ballast in the base of the lamp. You need to be experienced with working on 120 Volt circuitry. I just cut the existing connections to the ballast and used Wago Lever Nuts (or wire nuts) to splice the connections directly to the G23 bulb holder base.The light is bright and illuminates a 180 degree area. The built in metal finned heat sink on the back of the bulb is very effective. My thermal camera showed the front of the light was 85F and the heatsink was 140F. My OttLite has a reflector that works perfect with this bulb and surrounds the heat sink area so there is no danger of touching the hot surface.

We have 6 light fixtures in a series on one light switch that are inset flush mounted into a brick wall surrounding our raised terrace, installed 24 years ago when he house was built. The fixtures were fluorescent and some ballasts stopped working.I prefer LED and these unusual longitudinal shape/size bulbs were fortunately available.I removed the ballasts and rewired the hot wires together and cleaned out any unneeded metals parts in each fixture.I was able to replace the old fluorescent bulbs simply by using the same socket and these LED bulbs. They are unisided so light emanates from one side and the other is coated with a paint to allow reflection of light outward in one direction so be careful to install bulbs correctly. And be gentle as these have long skinny glass tubes.These are much brighter than the fluorescent bulbs were, and are going to last a lot longer and be a nice feature in our terrace lighting. It was a challenge over several years as the lights died so I knew I had to finally tackle this project.It would have been a nightmare to remove 6 metal light fixtures and replace them with new ones, would have cost about $1200 at the least expensive option I could find, plus those would not have fit the holes in the brick walls. Fixtures are pretty simple, a metal box with socket and wires connecting.It was a bargain to buy these LEDs and restore the existing fixtures. Thank you to the company that made these.

Got the 2 pak. Did the rewire for direct AC. I did have to file down a part of the connector end because a rise would not let the unit plug all the way in.1st lamp lasted a week then died. I tried to disassemble to troubleshoot(maybe bad connection/solder) but at one point could not pull it apart to get to the components.Installed 2nd lamp into same lamp unit. Has been working for the last 2 months so far. Good light. No flicker. Brighter than the fluorescent tube it replaced.

UPDATE 3/2018-The original 2 bulbs I ordered are still going strong. Instant-on and no hum, they provide a much better quality of light than the old fluorescent bulbs that they replace. If I didn't make it clear in my earlier comments, I am using these in desk lamps in my home office, and they are really terrific. I had one more lamp to convert that had the ballast built into the head of the lamp, and difficult to access. So, I ordered 2 more bulbs and tackled the job when I had plenty of time to be patient. I am rewarded with what is really a "new" lamp. Again, I stress that especially in this case, removing the old ballast is a job for someone who isn't afraid to disassemble things, work with internal electrical wiring, and make secure connections. But, this old lamp has always been my favorite one, due to its "retro" cool design from LEDU, and now it is even better than ever. These are terrific replacements for the original dim and yellow bulbs.ORIGINAL COMMENTS:Really terrific replacement for the old weak fluorescent bulbs that came with my 2 lamps years ago. I DID have to remove the old ballast transformer from the end of the wires and install a plain 110V plug, but that was easy and quick. If you use these with a ballast, you will damage the bulbs and possibly overheat something, so be aware that in most lamps, this won't be just plug-and-play.But, "converting" the lamps was easy and the reward is that they now work better and brighter than ever. If you are not comfortable with cutting stuff off a lamp cord and replacing the plug, then this probably isn't for you. You need to have some tools and not be afraid of wiring a lamp.

Fit as advertised, great output of supplemental lighting.

It's plenty bright, and is better than the compact fluorescent bulb that it replaced, but it wasn't clear to me that I was buying a bulb that throws the light in one direction. Yes, it does say "180 degree beam angle" in the description, but it is such an odd thing that it didn't sink in for me that it really meant what it said. It's hard for me to imagine why anybody would want this, unless maybe to illuminate a piece of art, but I can also hardly imagine one of the GX23 fixtures that were originally designed for compact fluorescent bulbs every having been used for directional illumination.
