GE 21 W T5 Fluorescent Tube, 1910 lm, 850mm

T5 LongLast™ High Efficiency lamps are triphosphor fluorescent lamps with 16mm outer diameter (5/8 of an inch). These lamps feature “Starcoat™ Technology” that delivers high quality triphosphor performance.

Available in 4 lengths, these GE High Efficiency T5 LongLast™ lamps bring lumen efficacy up to 105 lm/W. Combined with an extremely long service life, this range of lamps is ideally suited for commercial and retail application in both direct and combined direct/indirect luminaires.

High efficiency – up to 105 lumens per watt – for ongoing cost savings
Very long and reliable product life – up to 36,000 hours
High colour quality – CRI 85Ra
Low mercury content – 2.5mg
Reduced environmental impact (less waste) than T8 lamps
Smaller physical dimensions for improved light output control and smaller, more aesthetic fittings
Peak lumen output between 34-38°C
Designed only for HF-operation – higher lamp efficacy and lower ballast losses than conventional ballasts

GE Lighting T5 LongLast™ linear fluorescent lamps comply with IEC/EN 60061, IEC/EN 60081 and IEC/EN 61195 and IEC/EN 62471

Fluorescent Triphosphor

Triphosphor tubes have longer life, a lower mercury content, better colour rendering and higher lumen maintenance than their Halophosphate counterparts. The tubes are available in a variety of colour temperatures from 3000K (warm white) to 6000K (daylight).

• Extended life expectancy which can be increased by upto 20,000 hours with the use of high frequency luminaires.
• Shatter resistant versions available which retain the fragments in the event of a breakage.
• Option of triphosphor tubes with internal reflectors, which reduce waste light and increase light output by up to 75%.
• 16mm (T5) tubes provide a compact alternative to T8 tubes, offering peak performance at +35 °C and typically provide 5% more efficiency in most ceiling applications when compared to equivalent T8 tubes.

Nominal tube diameter - T5=16mm, T8=26mm, T9=29mm, T12=38mm
