Choosing the right light bulb
From colour temperature to dimming compatibility, here's everything you need to know to specify the perfect bulb for your space.
LED GU10 Lamps Explained
The most popular spotlight fitting in UK homes. Mains-voltage (240V) twist-and-lock cap, available in dimmable, non-dimmable, smart and tunable-white versions. Most modern downlights and spotlights take a GU10 lamp.
Shop GU10 MR16MR16 vs GU10
MR16 lamps are low-voltage (12V) and need a separate driver or transformer, while GU10 lamps run directly off mains. MR16 lamps typically give a tighter beam and cleaner optic, but installation is more involved.
Shop MR16 Dim to WarmDim-to-Warm Technology
Replicates the warm glow of a dimmed halogen — as the lamp dims, colour temperature drops from 2700K down to around 1800K. Perfect for living rooms, bedrooms and hospitality spaces where ambience matters.
Explore Dim to Warm Tunable WhiteTunable White Lamps
Adjust colour temperature across the full warm-to-cool range (typically 2700K–6500K) at any brightness. Ideal for kitchens, home offices and bathrooms where you want bright cool light for tasks and warm light to relax.
Shop Tunable White FilamentLED Filament Bulbs
The decorative look of a vintage Edison bulb with modern LED efficiency. Clear glass with visible filaments — perfect for pendants, exposed fittings and feature lighting where the bulb itself is on show.
Shop Filament SmartSmart Lamps & Voice Control
Control brightness, colour and scenes from a phone or via Alexa, Google Home or Apple HomeKit. No new wiring required — just swap the lamp and pair to the hub.
Shop Smart Lamps Anti-GlareReality LED Lamps
Our flagship range — designed to replicate the look and feel of halogen using a single Cree LED chip and a precision reflector. Smooth flicker-free dimming, CRI 90+ and that familiar halogen arc of light.
Discover Reality DimmingDimmer Compatibility
Most LED lamps need a trailing-edge or LED-specific dimmer — fitting them with an old leading-edge dimmer typically causes flickering, buzzing or a limited dimming range. Always check the lamp's compatibility list before specifying.

Bayonet (B22), Edison Screw (E27, E14), pin caps (GU10, G9, G4) — picking the wrong cap means the bulb simply won't fit. Use our visual cap guide to match what you've got at home.
