LED CFL bulbs are the energy-efficient alternative for your conventional PL-, Dulux- & Lynx lamps. The bulbs last more than 10 years, thus save money on replacement costs. The LED lights replace your current CFL bulbs directly, thanks to the same dimensions. This allows for quick and easy replacement without adjustments to the fixture. When choosing the correct LED bulb, always be sure to check the number of pins (2 or 4) of the bulb cap, otherwise the bulb will not fit. Also, the replacement wattage of the LED bulb should match the power of the current CFL bulb to prevent a difference in light output.
