Office Lighting Design
LED Panels, Lux Levels & Glare at Desks (2026)

Why office lighting needs a design

Staff spend the whole working day under the office lighting, most of it looking at screens and paper. Lighting that is too dim, too uneven or full of glare causes tired eyes and headaches, and lighting that burns all day in empty rooms wastes power. A fit-out is the cheapest time to get it right, because the ceiling is open and the wiring is being laid anyway.

The design does not need to be complicated. It needs a target level for each area, the right fittings, positions that suit the desks, and sensible switching.

How bright: lux targets for offices

Light falling on a surface is measured in lux. ClickBina's lighting design guide quotes Suruhanjaya Tenaga's building energy-audit guideline, which lists recommended average illuminance of about 300–400 lux for general offices, shops and reading or writing, and about 100 lux for corridors, passageways and stairs. The guideline references MS 1525, a code of practice for non-residential buildings.

Two practical points follow. The target is measured where the work happens, on the desk, not at the ceiling. And it is an average, so the layout matters as much as the fittings: dark gaps between rows of desks are what staff notice. To turn a lux target into a number of fittings, use ClickBina's lux and lumen calculator.

LED panels, downlights and linear fittings

For most SME offices the choice is simple: panels in a grid ceiling over the work areas, and anti-glare downlights where the ceiling is plasterboard.

Glare at desks and screens

Glare is the main complaint in badly lit offices. The lighting design guide recommends anti-glare heads with a deep recess, rated UGR below 19, or positioning fittings so the source is not in direct view when seated. In an office that means:

• Place fittings to the side of screens, not directly above or behind them, so they do not reflect in the monitor.
• Choose panels with a good diffuser rather than a bare, bright surface.
• Arrange desks so screens are side-on to windows, and use blinds to control sun on the glass.
• Avoid a single very bright fitting in a small meeting room; use two softer ones instead.

Colour temperature and colour quality

The lighting design guide explains that neutral-cool 4000 K helps with concentration and visual accuracy in workspaces, while warm white suits spaces for relaxing. For an office that usually means 4000 K in work areas and meeting rooms, with a warmer tone allowed in a lounge or pantry. Keep one colour temperature within a room so fittings do not look mismatched. The same guide suggests a colour rendering index of 80+ for general areas.

Lighting by zone

Coordinating with the ceiling

ClickBina's office ceiling guide explains that lights, grilles and detectors drop into tile positions in a mineral-fibre grid, which makes layout changes quick; that plasterboard is the practical way to build coves and lighting troughs; and that an open ceiling needs lighting suspended or track-mounted rather than recessed. Its advice applies directly: agree the light, grille, sprinkler and detector positions with the grid or board layout so nothing lands on a joint.

Switching, dimming and sensors

• Zone the switching so the row near the windows can be turned off on bright days.
• Fit occupancy sensors in meeting rooms, toilets, stores and corridors.
• Put a dimmer in meeting and training rooms used for presentations.
• Keep emergency lights and exit signs on their own circuits; they are part of the fire safety system.

New circuits, switching and sensors are electrical work. ClickBina coordinates it with the electrician during the fit-out rather than treating it as a decorating item.

Upgrading lighting in an existing office

Not every lighting job is a full fit-out. In an occupied office the usual choices are a like-for-like swap of old fluorescent fittings for LED panels in the same grid positions, or a re-layout where desks have moved and the old fittings no longer sit over the work. A swap is quicker and cheaper; a re-layout fixes dark desks and glare that a swap would only repeat. Either way, walk the floor first with the staff who sit there, note the dark spots and the screens that reflect a fitting, and work zone by zone or after hours so the office keeps running. Take the chance to add sensors in meeting rooms and stores while the ceiling tiles are out.

What the main items usually cost

These are ClickBina's published indicative Klang Valley ranges for 2026. LED panel prices vary widely by make and rating, so panels are priced from the layout.
