It's aimed at offices, warehouses, and retail spaces moving from fluorescent to LED without rewiring the fixture.\u003c\/p\u003e\n\u003ch2\u003eDo I need an electrician for this?\u003c\/h2\u003e\n\u003cp\u003eNo, if your fitting runs on a magnetic ballast: switch off the power, remove the old fluorescent tube, swap the fluorescent glow starter for the LED starter supplied with this tube, and fit the new tube — no rewiring involved. If your fitting uses electronic control gear (ECG\/HF ballast), this tube is not compatible as-is; the ballast has to be bypassed and the fitting wired directly to mains, which is a job for a qualified electrician.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e18W LED replacement for a 36W T8 fluorescent tube — roughly half the running wattage\u003c\/li\u003e\n\u003cli\u003eFits standard 1200mm G13 T8 fittings on magnetic ballast (starter swap required)\u003c\/li\u003e\n\u003cli\u003e~100 lm\/W efficacy, no mercury, no UV emission\u003c\/li\u003e\n\u003cli\u003eInstant start, no flicker or hum\u003c\/li\u003e\n\u003cli\u003eAvailable in 830 Warm White, 840 Cool White, and 865 Daylight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\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\u003eNominal Length\u003c\/td\u003e\n\u003ctd\u003e1200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003ctd\u003eG13 (T8)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLuminous Flux\u003c\/td\u003e\n\u003ctd\u003e1710 lm (830) \/ 1800 lm (840, 865)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e~100 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e160°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Life\u003c\/td\u003e\n\u003ctd\u003e15,000 hours (L70B50)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e≥80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBallast Compatibility\u003c\/td\u003e\n\u003ctd\u003eMagnetic\/conventional ballast only, with fluorescent starter swapped for the LED starter supplied.
