Every sectors guide on relumen8.com, in one place.
Every sector puts different demands on LED retrofit and sustainable lighting. Offices need LG7-compliant brightness and low glare; hospitality wants warmth and dimming; retail needs accurate colour; education and healthcare need durability, cleanability and easy maintenance. These guides look at how LED retrofit and sustainable lighting is used sector by sector, with the specification points, typical layouts and pitfalls we see most often across UK commercial projects.
What these guides cover
- Sector-specific lighting levels, glare and colour targets
- Typical layouts and fittings that work in each space
- Maintenance, controls and compliance points per sector
