New Halogen Threat

A new generation of mains-voltage halogen
reflector lamps designed to compete with low-
voltage halogen lamps promises cheaper and
simpler residential luminaires. But the new lamps
are far less efficient, and if luminaire
manufactures pick up the lamp on a large scale,
energy consumption in Europe could rise by tens
of terawatt hours.

Severe Energy Penalty
for New Type of Halogens
A new type of mains-voltage halogen reflector lamp promises cheap and simple residential luminaires. But their efficacy is very poor, and the energy penalty may be on the order of tens of terawatt hours in Europe alone.

DELight Has Got a Hold on
European Home Lighting
Modeling work carried out in connection with the European Domestic Efficient Lighting (DELight) study indicated that there is a residential lighting savings potential of 44 TWh, or 43 %, in the European Union«s 15 member countries. The DELight project based many of its findings on thorough hands-on field research.

Lighting Levels:
They Go Up and Down
A 19-country survey on recomended illuminance levels shows that there is little consensus on the "right" light level. The survey showed differences of up to a factor of 40 among countries for a similar task.
