The 2G11 base is a 4-pin plug-in fitting common in recessed ceiling panels, under-cabinet lighting and display case installations where the ballast is integrated into the fixture rather than the bulb.\u003c\/p\u003e\n\u003cp\u003eThis bulb is non-dimmable and rated at 18W on mains power, providing immediate energy reduction compared to the CFL equivalents it replaces. The 4000K colour temperature produces a neutral cool white light that suits office environments, retail spaces, workshops and commercial corridors where clear visibility is required without the warm cast of residential lighting. The elongated tubular profile distributes light evenly across the length of the lamp.\u003c\/p\u003e\n\u003cp\u003eThe LED technology increases operational life compared to CFL alternatives, reducing the frequency of replacements in fixtures mounted in ceiling voids or other access-restricted locations. The bulb carries an E energy rating under current UK regulations. Installation requires compatibility with 2G11 LED fixtures or retrofitted CFL fixtures with the ballast bypassed — verify fixture compatibility before ordering.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e18W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e2250lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003ePLL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003e2G11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (New Regs)\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e4,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eCool White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable?\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This Energizer LED PLL bulb is non-dimmable and must be used on standard mains switching only.

Check your existing fixture base before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this replace a CFL PLL bulb directly?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt depends on the fixture. LED PLL bulbs operate differently from CFL equivalents and may require the existing magnetic or electronic ballast to be bypassed. Some LED-compatible fixtures accept direct plug-in replacement.
