70W 6 foot T8 Daylight Fluorescent Tube, Industrial and Commercial Batten Lamp

A new generation of triphosphor coated fluorescent tubes. Using T8 triphosphor tubes in place of T12 and T8 halophosphor tubes increases light levels and extends lamp life, up to 20000 hours when used with electronic control gear, improves colour rendering performance and reduces maintenance and energy costs.

Applications:

• Industrial and commercial lighting (stores, offices, industrial areas, supermarkets);
• Special lengths in luminaires with non-standard dimensions, displays, furniture lighting, shops, bathroom luminaires;

Technical Features:

• High light output; almost constant lumen maintenance throughout life;
• High colour rendering (Ra85/Class 1B);
• Consumes 10% less energy than comparable 38mm fluorescent tubes;
• Excellent performance (lm/W) and increased luminaire efficiency (5 to 10%);
• Operates on conventional and electronic ballast;
