What’s driving the innovations?

Halogen lamps have now been around for a number of years. First invented in the late 1950s their increased popularity and widespread usage in multiple applications has seen production costs, and consequently prices, fall dramatically in recent years.

As the number of suppliers offering Tungsten Halogen lamps increases, and competition within the market sector intensifies, manufacturers are now seeking to gain competitive advantage through innovations in lamp technology.

Lamp Life

This was the first area in which engineers aimed to make improvements. Due to the luminous properties of Halogen lighting it is used in many retail environments in luminaries which can be hard to access. For this reason manufacturers wanted to offer a lamp which was not only more efficient but required less user maintenance. Most Mr16 Halogen lamps (those typically used in domestic situations) of just a few years ago lasted on average 2,500 hours. There are Halogen lamps now on the market that can boast a 10,000 hour life.

Energy Savers

The largest lighting expense is energy cost. General Electric, the inventors of the very first halogen lamp, sought to offer customers tangible cost benefits when in 2005 they introduced the GE Precise(TM) IR Energy Saving MR16 halogen lamp. Replacing a standard 50 watt MR16 with a 37 watt Precise(TM) IR will reduce energy consumption by 26%. It’s rated for 4,000 hours of life and is ideal for heat-sensitive applications.

UV filter Technology

UV Filter technology prevents unwanted UV components from being emitted in the light produced by halogen lamps. It is particularly effective in restricting the most harmful high energy UV-B and UV-C radiation, but also lessens the effects of low energy UV-A. It involves the ‘doping’ of the quartz envelope, which is enriched with UV absorbent material.

IRC Technology

Halogen IRC lamps represent one of the latest developments in halogen technology. Using an InfraRed Coating on the outside of the lamp, technicians improved luminous efficacy. This is due to the principle of ‘thermal recovery’, in which the heat, rather than dissipating, is reflected back onto the filament. The filament thus reaches operating temperature using less power.

Bulb Pinch Technology

This is a new manufacturing method applied to mains halogen lamps in which the filament is fixed in place within the envelope using glass knobs. As such they are not ‘free floating’, and able to withstand vibrations are more robust.

Halogen lamps in a low voltage environment have a consequently higher current and thus operate at higher temperatures. The filaments are therefore much thicker and do not require ‘pinch technology’.

Continual research and development by the leading manufacturers, including Osram, GE, Sylvania and Philips is leading to better quality, longer lasting, more efficient and safer lamps. This is fantastic news consumers, designers and lighting architects.
