Illuminance standards
The illuminance level on working surfaces is governed by Russian building code SP 52.13330.2016 (the updated version of SNiP 23-05-95). The key requirements:
| Space | Required, lx | Note |
|---|---|---|
| Office (computer work) | 300–500 | On the working surface |
| Meeting room | 300 | |
| Corridor | 50–100 | |
| Warehouse (general) | 50–100 | On the floor |
| Warehouse (picking area) | 200–300 | On the racking |
| Production shop floor | 200–750 | Depends on the visual-task grade |
Types of luminaires
Panel lights (Armstrong 600x600) — the standard for offices with a suspended ceiling. Power 36–40 W, luminous flux 3600–4000 lm. One luminaire lights about 4–5 m².
Linear (surface-mounted/suspended) — for spaces without a suspended ceiling. Length 600–1200 mm, power 18–72 W. They provide uniform lighting when installed in rows.
Industrial (High Bay) — for high ceilings (6–20 m): warehouses, production facilities, sports halls. Power 100–300 W, luminous flux up to 40,000 lm. The bell-shaped housing delivers directional light.
Downlights (recessed spots) — decorative and accent lighting: reception areas, meeting rooms, corridors.
Colour temperature
- 3000 K (warm white) — lounge areas, reception, conference rooms. Creates a cosy feel.
- 4000 K (neutral white) — the all-round choice for offices. Easy on the eyes, with good colour rendering.
- 5000–6500 K (cool white) — warehouses, production facilities, utility rooms. Maximum contrast.
For offices we recommend 4000 K — physiologically comfortable light for long hours of computer work.
Colour rendering index (CRI/Ra)
This shows how natural colours look under a given light source. Offices require Ra ≥ 80; design studios and medical facilities require Ra ≥ 90.
Calculating the number of luminaires
A simplified formula: N = (E × S) / (F × η), where:
- E — required illuminance (lx)
- S — floor area of the space (m²)
- F — luminous flux of a single luminaire (lm)
- η — utilisation factor (0.4–0.6 for typical spaces)
Example: a 50 m² office requiring 400 lx, panels rated at 4000 lm, η = 0.5. N = (400 × 50) / (4000 × 0.5) = 10 luminaires.
Energy efficiency
LED luminaires consume 5–7 times less energy than fluorescent fixtures at the same luminous flux. Service life is 50,000 hours (12+ years at 12 hours of operation per day).
