All guide guides

• What is recessed lighting? A guide for commercial interiors — Recessed lighting is installed into the ceiling void so the light sits flush with the ceiling, giving clean, uncluttered interiors with linear profiles or downlights.
• Recessed linear lighting: a complete specification guide — Recessed linear lighting creates flush lines of light in the ceiling; specify it by length, output, optic, trim type, controls and coordination with the ceiling void.
• Architectural downlights: how to choose for commercial projects — Choose architectural downlights by beam angle, glare control, output, colour quality, cut-out size, IP rating and controls, matched to the space and ceiling.
• Recessed vs surface-mounted lighting — Recessed lighting sits flush in a ceiling void for a clean look, while surface-mounted fittings fix directly to the ceiling, ideal for concrete soffits and shallow voids.
