GU10 Bulbs

GU10 bulbs are compact, mains-powered spotlight bulbs designed for directional lighting in residential and commercial interiors. With a twist-and-lock base and a wide range of beam angles and colour temperatures, GU10 bulbs are ideal for recessed lighting, track fixtures, and accent illumination. Available in LED and halogen formats, they offer energy efficiency, longevity, and versatile styling.
