AR111 LED bulbs for commercial and accent lighting

AR111 LED bulbs are designed to provide powerful, controlled and directional illumination. Their approximate diameter of 111 mm and reflector format make them a popular solution for shops, window displays, hotels, restaurants, galleries, museums, showrooms and homes with technical lighting installations.

At DomiLED you will find AR111 LED lamps with different power ratings, luminous outputs, beam angles and colour temperatures. They provide an efficient replacement for traditional AR111 halogen lamps, reducing electricity consumption and heat generation while maintaining practical illumination for professional applications.

AR111 bulbs with a G53 cap

Many AR111 bulbs use a G53 cap, consisting of two contacts spaced approximately 53 mm apart, and operate at low voltage through a compatible transformer or driver. Other configurations are also available, so always check the cap type and operating voltage of the luminaire before ordering.

When replacing a halogen AR111 lamp with an LED version, transformer compatibility must be verified. Some older transformers require a minimum electrical load and may cause flickering, unexpected switching or irregular operation when connected to a lower-power LED bulb.

Beam angle and luminous intensity

The beam angle determines the size of the illuminated surface. A narrow beam concentrates the light and is suitable for highlighting products, artwork, tables, architectural features and specific areas. A wider angle distributes the light across a larger surface.

For accent lighting, consider both lumens and candelas. Lumens indicate the total amount of light emitted, while candelas express the luminous intensity in the main direction of the beam.

Colour temperature and colour rendering

Warm white creates a comfortable atmosphere in restaurants, hotels, living rooms and decorative spaces. Neutral white displays products and materials more naturally, making it a popular choice for shops, window displays, galleries and exhibitions.

For commercial applications, the colour rendering index or CRI should also be considered. A high CRI reproduces the colours of products, fabrics, food, artwork and decorative elements more accurately.

If the installation includes a brightness controller, choose a dimmable AR111 LED bulb and verify the compatibility of the bulb, transformer and dimmer. Explore our selection of AR111 G53 LED bulbs and find the correct power, beam and light colour for each project.
