2pcs 4Pin Gx24q CFL to E26/E27 Medium Screw LED Bulb Base Holder Light Socket Adapter Converter. NOT Plug and Play, Need Rewire/Bypass Ballast. (2-Pack)

The only "job" these adapters have is to transfer the flow of electricity from the power source to the device. That's what the metal contacts are for. The adapter itself is not mechanical, it has no electronics or moving parts - there is nothing that needs to "work." Most of the poor reviews for these adapters are from people who think they are plug and play. They are not. CFL bulbs use a ballast. LED lights do not. In order for the LED to work, the ballast must be removed, taken out of the equation. This means you literally have to go into the ceiling/wall, find the junction box and snip the wires to bypass the ballast. I've done 5 of these in my home and they all work perfectly.

Does not last more than 2 min with an LED Light. The Light seems to be over heating and stops working.

Disappointed that these didn’t work out. I was putting my Phillips Hue bulbs in and needed these to convert plug type. Connected 4-pin bulb worked fine. Tried conventional bulb in connector and bulb wouldn’t stay on. Tried both in box and complete failure. Had to give up after two hours of trouble shooting and going up and down two stories on ladders.

It works.

Edit to original review. Original review was negative. I had wired correctly w bypass of ballast. Problem was the wiring to the fixture was done with other lights on same circuit I had also removed them for replacement. After replacing both lights everything worked fine Apologies to seller for negative review
