B-class halogen bulbs / improved incandescent bulbs

A special infrared coating results in further efficiency benefits for filament lamps.

 

An infrared coating applied to the bulb improves the energy efficiency by more than 45% compared to the best conventional incandescent bulbs. However, this is only possible with low voltage lamps. A transformer is in fact needed to make this technology available for mains voltage lamps.

The transformer can be a separate unit or a component integrated into the luminaire. It can also be integrated into the bulb itself, which can then replace conventional incandescent bulbs in the same luminaire. As with the C-class lamps both the special socket capsules and the improved incandescent bulbs exist in B-class.

The B-class improved incandescent bulbs are currently only available up to the equivalent of a 60W conventional incandescent bulb.

This type of lamp can last up to 3000 hours – three times longer than conventional incandescent bulbs – and is dimmable on any dimmer.
