Bonlux 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 Cold White 6000K

I had to remove the ballast circuits from my old fittings which was simple to do and once done the lights are very effective without being too bright.

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.

The bulb worked for two switches and now doesn’t work.

The product exactly met expectations for a bargain price.I have an OttLite fluorescent table lamp that experienced an electronic ballast failure. What to do?Option 1: replace the electronic ballast. No go because OttLite doesn't provide replacement ballasts and a generic replacement made no sense for the cost and aggravation of tracking down.Option 2: replace the electronic ballast with a magnetic ballast. No go. Again cost (throw in extra cost because a new non-electronic lamp bulb would also be needed) and the aggravation of tracking down, along with questions of whether a magnetic ballast would physically fit in the lamp base factored in made this an unappealing idea.Option 3: Bonlux led replacement lamp. Hurray!! We have a winner. This lamp is a perfect fix at a great price. Two lamps for under $15, equal light out put to the old fluorescent and no more ballast issues to contend with. Removed the old ballast (this retrofit lamp does not use a ballast at all, rewired the connections, turned on and voila a good as new OttlLite saved from the scrap pile.

Absolutely high quality installed in kitchen display cabinet as old cfl lamps failed, as an electrical engineer you Must remove a ballast and wir via switch to the 240 v supply you can not wire in series each lamp has to have a mains supply hope that clears perhaps that's why some customers have had problems and given a low score follow my advice they are extremely good
