Lighting guides & advice
LED lighting uses up to 80% less energy than traditional halogen and lasts 25,000–50,000 hours. With warm white options down to 2700K, modern LEDs deliver beautiful, efficient light for every room.
Read more Downlights Choosing the Right DownlightFixed or adjustable, recessed or surface-mounted, downlights suit most ceiling types. Key considerations include beam angle, colour temperature, and IP rating for bathrooms and outdoor use.
Read more Outdoor Lighting Garden & Exterior LightingFrom IP65-rated spike lights to marine-grade coastal fittings, outdoor lighting requires the right weatherproofing for each location. Combine wall lights, uplights, and path lighting for a layered effect.
Read more Smart Controls Wireless Lighting Control SystemsWise Controls and Lutron systems allow full scene setting, dimming, and scheduling without rewiring. Ideal for new builds, extensions, and retrofit projects where flexibility is essential.
Read more Bathroom Lighting IP Ratings & Bathroom ZonesBathroom lighting must comply with IP zone requirements. Zone 1 (above the bath/shower) requires IP65 minimum; Zone 2 requires IP44. Always confirm ratings before specifying fittings.
Read more Track Lighting Track & Linear Light SystemsTrack lighting offers flexible, adjustable illumination ideal for kitchens, retail, and galleries. 48V magnetic track systems allow tool-free repositioning of spotlights, pendants, and linear modules.
Read more Colour Temperature Warm White vs Cool White2700K–3000K (warm white) suits living areas and bedrooms; 3500K–4000K suits kitchens and offices; 5000K+ (daylight) suits task lighting and commercial spaces. Mixing temperatures in one room is rarely advisable.
Read more Dimming Dimmer Switches & LED CompatibilityNot all LED drivers are dimmable. Always check compatibility between the lamp, driver, and dimmer switch. Leading-edge dimmers suit most LED loads; trailing-edge dimmers are preferred for very low wattage LED circuits.
