Choosing commercial downlights.
29 products are shown here, with efficacy of up to 140 lm/W (Holp). Control options include DALI and Casambi. Colour rendering is CRI 80 or 90. Every fitting is supplied by 299 Lighting from London and Bristol. We reply to quote requests within one working day, and lighting layouts are included when we supply.
Downlights give clean, even light from a small aperture, which makes them the standard choice for corridors, receptions, meeting rooms and washrooms.
Check the ceiling first: recessed downlights need a void and a cut-out; surface-mounted versions suit exposed concrete and plasterboard with no void.
For offices, choose low-glare optics (UGR 19 or below to CIBSE LG7). For hospitality and retail, a warmer colour temperature and CRI 90 make materials look their best.
Frequently asked questions.
Which product in this range is the most efficient?
Holp has the highest efficacy in this range, at up to 140 lm/W depending on the configuration.
What dimming and control options are available?
Products in this range are available with DALI or Casambi control. Each product page lists the options for that fitting.
What is the difference between recessed and surface-mounted downlights?
Recessed downlights sit inside the ceiling void and need a cut-out. Surface-mounted downlights fix directly to the ceiling, so they suit exposed soffits or ceilings with no void.
Which downlights are best for offices?
Low-glare downlights with a UGR of 19 or below meet CIBSE LG7 guidance for desks and screens.
Can downlights be used in bathrooms?
Yes, as long as the IP rating suits the zone. IP44 or IP65 downlights are typical near showers and basins.
