E-Simpo 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)
- Need Ballast Removal. 2pcs/lot, sample pack. with Base depth is 15.5mm/0.6 inches. Short version 4pins,Suitable for G24Q-1, G24Q-2.G24Q-3, GX24q-1,GX24q-2,GX24q-3 socket;
- NOT FOR DIY!!! NEED REWIRING! Removing or Bypassing the ballast INSIDE the light fixture is REQUIRED. CONSULT AN ELECTRICIAN IF YOU ARE UNSURE. DO NOT OPERATE THE LED BULB WITH BALLAST IN THE FIXTURE. DOING SO WILL LIKELY DAMAGE THE BULB.
- Physically Change the socket contact, twist into existing GX24Q socket and transform the fixture to fit any standard E26 E27 medium size bulb. BUT mostly GX24Q CFLs are with an electronic ballast inside, which will cause the LED bulb flickering, burnt, hot or smell, and damage the electrical parts inside the bulb.
- 4P Conductive, E-Simpo's New Generation. PBT Housing,Copper Contact.Suitable for All Voltage: 100-240V,Works for 4-Pin CFL with G24q-1 Base:10w 13w Quad Tube; GX24q-1 Base:10w 13w Triple Tube;G24q-2 Base:18w Quad Tube;GX24q-2 Base:18w Triple Tube;G24q-3 Base:26w 32w Quad Tube;GX24q-3 Base:26w 32w Triple Tube
- There are some LED Driver who can be compatible with the ballast, no LED Driver can be compatible with all the ballast. So the best thing is bypass or remove once we want to change CFL to LED Lamp. When we remove pin-based CFL, we only removed the lamp, the ballast is still working in front fixture; even we change to E26/E27 CFL, there will be 2 ballasts, the light will not work.
