INTRODUCTION

Fluorescent lamps are very economical with efficacies of up to 104 lm/W. In addition to this energy efficiency the wide range of different colours of light available means that the best possible light for any visual requirement can be chosen. A wider range of wattages and lengths, straight and circular lamps and others designs provide an optimum lighting solution for any application.

Fluorescent lamps can be used for almost every application, including offices, school, industry, exterior lighting, shops, museum, hotels and any other type of building or business.

LIGHT COLOUR OR COLOUR TEMPERATURE

The light colour is the intrinsic colour of the light warmth or coolness of the lamps emitted by a lamp. It is characterised by the colour temperature (in Kelvin). The colour temperature of a lamp is the temperature at which a "black body" (defined by physics theory) has the same colour as the lamp concerned. For general interior lighting purposes DIN 5035 divides light into 3 colour classes: warm white below 3300K, neutral white below 3300 to 5000K, cool daylight above 5000K.

CIRCULAR FLUORESCENT LAMPS

TLE Circular Fluorescent Lamps

The main advantage of the circular design is providing non-directional light for functional and decorative luminaires. Average life 8,000 hours.

COMPACT FLUORESCENT LAMPS - NON-INTEGRATED

PLC Compact Fluorescent Lamps

PLC lamps are compact, single-ended fluorescent lamps. They have a two-pin base with an integral starter switch providing almost instant starting. Their compact size and high light output offers an energy saving of about 80% compared to an equivalent wattage of a GLS lamp. They offer excellent colour rendering and are available in a few colour temperatures. All require external control gear, which normally comes complete with the luminaire. Average life 8,000 hours.

PLS Compact Fluorescent Lamps

PLS lamps are compact, single-ended fluorescent lamps. They have a two-pin base with an integral starter providing almost instant starting. Their compact size and high light output offers an energy saving of about 80% compared to an equivalent wattage of a GLS lamp. They offer excellent colour rendering and are available in two colour temperatures. 4 pin versions are also available for starterless electronic circuits. Average life 8,000 hours.
