LED lighting upgrades for commercial premises: what to consider

What to think about before switching a commercial building to LED, from light levels to controls and emergency lighting.

LED lighting upgrades for commercial premises: what to consider

Quick answer: Look at light levels for how each space is used, add sensible controls such as presence and daylight sensors, check your emergency lighting, and plan the work to avoid disruption.

Why businesses upgrade

LED fittings use less energy than older fluorescent and halogen lighting and usually need far less maintenance. For many commercial buildings, lighting is one of the easier places to cut running costs.

Get the light levels right

Different spaces need different amounts of light. An open plan office, a warehouse and a corridor all have different needs. A good upgrade looks at how each area is used rather than swapping fittings like for like.

Think about controls

  • Presence detection: lights switch off in empty rooms, meeting rooms and toilets.
  • Daylight sensing: fittings near windows dim when there's enough natural light.
  • Zoning: areas can be switched separately instead of a whole floor at once.

Don't forget emergency lighting

An upgrade is a good time to review emergency lighting. Many LED fittings are available with integrated emergency packs, and it's worth making sure coverage and testing arrangements are up to date.

Ceilings and access

Lighting upgrades often involve ceiling work, especially in suspended grid ceilings. Planning the lighting and ceilings together avoids damage, repeat visits and mismatched finishes.
