The production and importation of directional mains-voltage halogen bulbs was banned on 1 September 2016 and non-directional halogen bulbs followed on 1 September 2018. [6] Australia banned some halogen light bulbs above 10W from September 2021 in favour of eco-halogen bulbs, [ 7 ] later than the planned date of September 2020 [ 8 ] to keep the ...
Under ECE regulations, H1 lamps are required to emit white or selective yellow light. [1] U.S. regulations require H1 lamps to emit white light. [2] Under both ECE and U.S. specifications, the allowable range of white light is quite large; some H1 lamps have a slight blue or yellow tint to the glass yet still produce light legally acceptable under the requirement for white light.
The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...
Halogen lamps are a type of incandescent lamp using a tungsten filament in bulbs that have small amounts of a halogen, such as iodine or bromine added. This enables the production of lamps that are much smaller than non-halogen incandescent lightbulbs at the same wattage. The gas reduces the thinning of the filament and blackening of the inside ...
I've seen references to the fact that halogen lamps aren't very efficient. For example: "But like most conventional forms of domestic lighting, halogen spot lamps are terribly inefficient and use far more power than is necessary since nearly all the energy is wasted as heat, which brings with it the further problem that they run incredibly hot and often require fire-rated covers.
