Luxrite PL LED CFL Replacement - Not sure which light color you want in your space or need to find the right fit? Our CFL LED bulbs have a selectable color temperature switch which can be adjusted to your preferred color output. Select between 3500K natural white, 4000K cool white, or 5000K bright white. An energy efficient way to replace your double tube and triple tube compact fluorecent light bulbs. Each pl led bulb has a universal base which can fit all G24D, G24Q, and GX24Q sockets with 2-pin or 4-pin requirements. These only have 2 pins but is used in a ballast bypass installation so it does not require all pins. Since no ballast is required, you can also connect them to either 120v or 277v connections. These will produce more light than 26W, 32W, and/or 42W standard cfl tube light but only uses a fraction of the power which means you save on your energy costs. Use in your interior or exterior space since each light is damp location rated to handle tougher conditions.
