Light Bulbs & Lamps

Browse over 500 light bulbs and lamps in stock at Mr Resistor — from everyday GU10 and E27 LED replacements through to specialist halogen, fluorescent, metal halide, and decorative filament bulbs. Whether you're matching a fitting on a heritage project, specifying high-CRI lamps for a retail or gallery install, or simply replacing the bulbs in your kitchen downlights, we hold the stock and the technical knowledge to help you get it right first time. Use the filters to narrow by cap type (GU10, E27, B22, E14, MR16, AR111 and more), lamp shape, colour temperature, CRI, beam angle, wattage, dimmability, and voltage.

Our own ranges — including Focus LED, Super Focus LED, Reality, and Optic narrow-beam lamps — are developed in-house for consistency of colour, flicker-free dimming, and long service life, with most lines stocked in deep quantities for trade and contract use. Alongside these we carry leading lamp brands and hard-to-find specialist sources for theatre, display, signage, and architectural applications. Most bulbs are dimmable with a compatible driver or dimmer, and our team can advise on retrofit compatibility, lumen output, CRI requirements, and lamp life.
