Guide to Emergency Lighting 2026 (UK) | 299 Lighting

299 Lighting — Wed, 04 Nov 2026 16:33:46 GMT

Emergency lighting is a broad, multi-layered subject that involves every part of a project team. Correctly specified emergency lighting is not just a couple of well-placed emergency fittings and exit signs. It starts with a risk assessment, runs through design, product selection and installation, and continues for the life of the building through testing, records and verification.

The rules have also moved on. Between 2024 and 2025, all three of the core UK emergency lighting standards were revised. BS EN 1838 and BS EN 50172 were reissued in 2024, and the UK code of practice, BS 5266-1, followed with a full revision in October 2025. If your specification, design template or O&M manual still references the 2016, 2013 or 2004 editions, now is the time to review it.

We've rewritten this guide to cover everything you need to know to get the best emergency lighting in 2026 and beyond.

8 Best Commercial Downlights for Offices and Lobbies in 2026

299 Lighting — Fri, 09 Oct 2026 09:00:00 GMT

Selecting the right commercial downlights for offices, lobbies, and circulation areas requires balancing visual comfort, energy efficiency, and compliance with British standards. 299 Lighting works alongside architects, lighting designers, and electrical engineers to specify downlights that meet LG7 requirements while delivering the clean aesthetic modern fit-outs demand.

How to Meet CIBSE LG7 for Office Lighting in 2026

Key Takeaways: How to Meet CIBSE LG7 for Office Lighting in 2026

CIBSE LG7 2023 sets task illuminance at 300 lux for screen-based work and 500 lux for paper-based tasks, with UGR limits of 19 or below.
Context modifiers let you adjust recommended lux levels based on occupant age, task complexity, and the specific nature of each workspace.
Cylindrical illuminance at sitting and standing heights is now a requirement for offices where video conferencing takes place.
299 Lighting delivers fully compliant LG7 office schemes with in-house photometric calculations, UGR analysis, and technical design support.
Wireless control systems with daylight linking, occupancy sensing, and scene setting help reduce energy consumption while meeting compliance.

What Is CIBSE LG7 and Why Does It Matter for Office Lighting?

CIBSE Lighting Guide 7 (LG7) is the UK industry standard for office lighting design. Published by the Society of Light and Lighting (SLL), the guide outlines how to create visual environments that support productivity, comfort, and wellbeing in workplaces.

How to Choose Commercial Downlights for Offices in 2026

299 Lighting — Fri, 02 Oct 2026 09:00:01 GMT

Key Takeaways: How to Choose Commercial Downlights for Offices

Commercial downlights for offices must meet UGR ≤19 glare requirements under BS EN 12464-1:2021 to ensure visual comfort at workstations.
Beam angle selection, narrow (10°–24°), medium (25°–40°), or wide (60°–90°), determines whether downlights serve accent, task, or ambient lighting roles.
Ceiling integration matters: recessed trimless fittings suit contemporary fit-outs, while surface-mounted options work where void depths are limited.
299 Lighting supplies commercial LED downlights with DALI and Casambi controls, emergency integration, and outputs ranging from ~1000–3000+ lumens for office applications.
Colour temperature (3500K–4000K for offices) and CRI 80+ ensure neutral daylight-balanced environments with accurate colour rendering.

Why Commercial Downlights Remain a Staple for Office Lighting

When it comes to specifying lighting for modern offices, downlights continue to hold their ground against linear alternatives. Their discreet profile, minimal visual impact on the ceiling plane, and ability to deliver precise light distribution make them a natural choice for reception areas, cellular offices, meeting rooms, and circulation zones.

Emergency Lighting Design in the UK 2026 Guide

299 Lighting — Tue, 29 Sep 2026 09:00:01 GMT

When the mains power fails in a commercial building, your emergency lighting system becomes the difference between a safe evacuation and a dangerous situation. For architects, lighting designers and electrical engineers working on UK commercial projects, getting emergency lighting design right means navigating British Standards, building regulations and practical installation challenges.

Lighting and Cognitive Performance: What the Evidence Says

299 Lighting — Tue, 22 Sep 2026 09:00:00 GMT

We accept without question that temperature, noise, and air quality affect how well people think at work. The evidence that lighting has equivalent and measurable effects on cognitive performance is at least as strong and, in some respects, more precisely understood. Yet it remains significantly underweighted in most workplace design and specification briefs. This post examines what the research establishes about light and cognition and translates that into practical guidance for commercial settings.

Light, Stress and the Body's Alarm System: The Research

299 Lighting — Tue, 15 Sep 2026 09:00:01 GMT

Previous posts in this series have examined how light shapes mood, cognition, sleep, and visual comfort. This post focuses on a different dimension: the relationship between light and the body's physiological stress response. It is an area where the evidence is more nuanced than popular coverage suggests, and where the commercial lighting implications are genuinely significant.

Lighting, Headaches and Visual Fatigue: The Evidence

299 Lighting — Fri, 11 Sep 2026 09:00:00 GMT

Of all the ways that lighting affects health in the workplace, the effects on visual comfort are the most immediately felt. Eye strain, headaches, and blurred vision are among the most commonly reported occupational complaints in office environments. They are also the symptoms most directly and causally connected to the physical light environment, making them both an important topic for this series and an area where design and specification decisions have unusually clear practical traction.

Light and Sleep: Why What Happens in the Office Follows You Home

299 Lighting — Tue, 08 Sep 2026 09:00:00 GMT

Sleep is the most restorative process available to the human body. It is when memory consolidates, immune function restores, emotional regulation resets, and the brain clears metabolic waste that accumulates during waking hours. And yet the quality of sleep a person gets tonight is shaped, to a meaningful degree, by the light they were exposed to today, including the light in their workplace.

Lighting, Alertness and Workplace Performance: The Evidence

299 Lighting — Fri, 04 Sep 2026 09:00:01 GMT

Most commercial lighting briefs are written around visibility: making sure people can see what they are doing comfortably and safely. That is the right starting point. But a growing body of evidence suggests that light does not simply enable vision. It actively shapes the state of the brain behind the eyes, influencing alertness, reaction time, working memory, and the capacity for sustained concentration. For anyone designing or specifying workplaces, that evidence is worth understanding clearly.
