MASTER PL-C 4-pin

The MASTER PL-C 4-pin range of lamps forms part of

the compact fluorescent nonintegrated family of lamps.

Compact long-arc low-pressure mercury discharge lamp with

a clear glass envelope consisting of four parallel narrow

fluorescent tubes welded together at the bottom and

near the ends. It has a four-pin base without the starter and

capacitor. It is equipped with two preheated tungsten

electrodes and filled with a mixture of saturated

mercury vapour and an inert buffer gas.

Well adapted to be used in combination with electronic gear,

offering the possibility of controllable light output,

HF operation and independence from the supply system.

It is for instance, possible to use AC and DC supply and

a wide range of supply voltages. Dimming is possible.

The lamp characteristics are influenced by operating conditions

and control gear used. The lamp performance is strongly

governed by the temperature of the coolest spot,

which is influenced by the lamp position.

MASTER PL-C is a breakthrough in compact fluorescent lighting.

By making use of the unique Philips-invented bridge technology,

light output has been optimised for the relatively high temperatures

inside the luminaire, providing up to 6 % higher system light output.

Furthermore the advanced coating technologies result in

12 % lumen maintenance improvement at average rated life.

MASTER PL-C lamps contain only 3 mg of mercury.

Applications

- General or supplementary lighting in professional environments or the home.

- Recessed or surface-mounted downlighters, wall units, pendant lamps and table lamps.
