Commercial Lighting Mistakes
Eight repeat-offender mistakes in commercial lighting, glare, CCT, controls and the gap between specification and commissioning.
Eight Common Mistakes
- No UGR data, glare appears on day one
- CRI 80 in retail and hospitality, merchandise looks dull
- Single CCT across an entire building with mixed functions
- No daylight integration on perimeter zones
- No commissioning, scenes default to factory presets
- PIR sensors with the wrong timeouts, lights cycle randomly
- Pendants used as ambient with no UGR check
- W/m² over budget, energy compliance issues at handover
Why These Repeat
Most are scoping failures, not technical ones. Once a project enters tender without lux, UGR, uniformity, CCT, CRI and W/m² specified together, contractors substitute the cheapest match.
Professional Recommendation
Specify all six metrics in tender documents. Reject substitutions that fail any single one. Always budget commissioning.
Lighting Intelligence by Alya
At Ashwamedha Design Solutions, this is part of our Lighting Intelligence practice, every recommendation is validated through DIALux simulation, lux calculations and visual comfort analysis before it reaches a construction site. Alya, our lighting intelligence platform, packages this thinking into reusable design tools.
Frequently Asked Questions
Why does commissioning matter so much?+
Hardware delivers potential. Commissioning tunes timeouts, scenes, dimming curves and daylight thresholds, the difference between "installed" and "feels right".
Is W/m² regulated?+
Yes, ECBC (India) and ASHRAE 90.1 set maximums. Above 8 W/m² for offices usually fails certification.
