AR111 lamps are used for general illumination as well as spot lighting. The “AR” is short for Aluminium Reflector and the 111 refers to the 111mm diameter. The G53 base is 53mm long and has two screw terminals. Commonly found in 12V, they require a transformer to reduce mains voltage down to their operating voltage.
Ensure that an appropriate beam angle is chosen for your lighting situation. The narrow beam angles (as small as 4°) are the perfect choice for spot lighting merchandise and showcase items. A wider spread is ideal for general illumination.
While LED versions are becoming increasingly popular due to their high efficiency and long life, Lamp Replacements Australia still stocks a range of halogen AR111 lamps. The Philips ALULine, MASTERLine and Osram Halospot series are reliable and available in different beam angles and wattages. The advantage over LED alternatives is their high Colour Rendering Index and ease of dimming, but the higher energy consumption and shorter life may make LED options a smarter choice.
