What are PLL bulbs used for?
LED PLL lights are great for replacing CFL light fixtures with a 2G11(4-pin) base. Depending on your current light fixture ballast compatibility, these bulbs can easily plug-and-play into your existing 4-pin light fixture. While some are ballast compatible, others require the existing ballast to be removed in order to run off line voltage. PLL bulbs are commonly used as energy efficient replacements to commercial light fixtures, such as downlights, ceiling lights, and fluorescent linear fixtures.
