The twin-tube PLS form factor delivers 370 lumens of cool white 4000K light through an LED core that switches on instantly without the warm-up delay or flicker characteristic of older CFL technology.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial and residential applications where compact fittings are already installed, this bulb slots directly into existing G23 2-pin sockets without rewiring or adaptor plates. The 4000K colour temperature produces a neutral white that suits office task lighting, bathroom mirror lights, retail display cases, and hospitality washroom fittings where a clean, functional light is required rather than a warm ambient glow.\u003c\/p\u003e\n\u003cp\u003eThe 4.5W LED draws half the power of the 9W CFL it replaces while delivering comparable light output, which reduces running costs in fittings that operate for extended hours. The bulb is rated energy class E under current UK regulations and carries a 30-year lifespan claim from Energizer based on typical domestic use patterns. The twin-tube shape maintains even light distribution across the length of the bulb, avoiding the hot-spot effect sometimes seen in single-tube LED retrofits.\u003c\/p\u003e\n\u003cp\u003eThis is a non-dimmable bulb and must not be used with dimmer switches or variable controls. The G23 2-pin base is found in many compact fluorescent fittings produced from the 1990s onwards, particularly in task lighting and architectural detail fittings where space constraints rule out standard ES or BC bulbs.\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\u003e4.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e370lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003ePLS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eG23\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\u003eWhat does G23 2-pin mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eG23 refers to a compact fluorescent lamp base with two parallel pins spaced 23mm apart. This base type is common in compact desk lights, cabinet fittings, and architectural detail lighting produced from the 1990s onwards. The bulb pushes into the socket and is held by a twist-lock or clip mechanism depending on the fitting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this replace my old 9W CFL?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. This 4.5W LED is designed as a direct replacement for 9W compact fluorescent PLS bulbs with a G23 base. The light output is comparable at 370 lumens, but the LED switches on instantly and uses half the power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used with a dimmer?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This bulb is non-dimmable and must not be used with dimmer switches or variable controls.
