Push-Fit 2-pin and 4-pin Light Bulbs
Push fit bulbs are available in 2-pin and 4-pin versions and offer an energy-efficient, easy-to-install alternative to traditional incandescent lights. Most PLC and PLL bulbs are compact fluorescents (CFLs), however, you can now find even more efficient LED alternatives. These are designed to fit directly into existing fittings, making it easy to upgrade. These bulbs are most commonly used in integrated light fixtures, such as shaver lights and cabinet lights.
