AR111 Halogen lamps are most commonly used in commercial spotlights, downlights and some residential lights.We have standard AR111 Halogen Reflector are named after their diameter of 111mm, there is a good variety of beam angles to select from so take care to select what will work best for you. There are standard AR111 lamps as well as Energy Efficient (EE) lamps. EE halogen lamps either use different combinations of gas (usually Xenon) to achieve a more efficient lamp or the inner bulb has an Infra-Red Coating (IRC) that reflects heat into the filament. This allows for the same light and heat output but less wattage input.
To figure out how efficient these lamps are we give a lumens per watt value (lm/w) which will help you to compare two products quickly.
