A switch on the endcap allows selection between three colour temperatures — 3000K warm white, 4000K neutral white, or 6500K daylight — set once during installation to match the room's lighting requirements.\u003c\/p\u003e\n\u003cp\u003eDesigned for retrofitting into existing T8 fluorescent fittings, the tube works in both switch-start and electronic ballast configurations after the ballast is bypassed and the tube is wired directly to mains. This conversion eliminates ballast failure as a source of downtime and reduces running costs from approximately 58W (fluorescent tube plus ballast losses) to 22W. Offices, workshops, warehouses, retail stockrooms and garages switching from fluorescent to LED typically see 60-65% reductions in lighting energy.\u003c\/p\u003e\n\u003cp\u003eThe 1500mm tube length fits standard 5ft batten fittings and provides even light distribution along the full length without the flicker or warm-up delay common to aging fluorescent tubes. The frosted polycarbonate sleeve diffuses light smoothly, avoiding the harsh line-source glare of clear tubes. At 2640 lumens the tube provides similar brightness to a 58W fluorescent but with a 25,000-hour rated lifespan, reducing lamp replacement frequency in high-use environments.\u003c\/p\u003e\n\u003cp\u003eThe colour temperature selector on the endcap uses a slide switch marked with 3000K, 4000K and 6500K positions. Warm white (3000K) suits hospitality and residential spaces where a softer tone is preferred. Neutral white (4000K) works in offices and commercial environments needing balanced task lighting. Daylight (6500K) provides the highest colour contrast for inspection work, technical drawing and product photography.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e22W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e2640\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eTube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eT8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003eVariable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eVariable\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\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan this tube be fitted directly into an existing fluorescent fitting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe tube requires the existing ballast to be bypassed and the tube wired directly to mains voltage.
