Philips 150 Watt heating bulb

Glass bulb with improved reflector.

Bulb with harder glass than the old model. The reflector has been improved, which gives us more heat over a larger surface.

Red bulbs give 75% less light than white ones, but the infrared radiation and heat they emit are equal to that of white bulbs.

White bulbs have been developed specifically for use in pigs and poultry. The red ones are suitable for use with all types of animals.
