Whether you’re looking for warm and ambient LED spotlights to add a softer lighting dimension to your at-home relaxation areas (e.g. bedrooms, living rooms, conservatories), or whether you’re searching for LED spotlight bulbs for use in practical areas such as kitchens, bathrooms, hallways, and workspaces, our complete range of LED spotlights has everything you need.
For example, if you wish to set the tone, check out GU10 LED bulbs warm white to help you achieve a cosy yellow/orange lighting backdrop, or conversely you may wish to check out GU10 cool white if you’re looking for the ideal way to illuminate action areas where you require a little more focus and concentration.
When introducing energy saving LED spotlights into the home, you may wish to consider opting for dimmable LED spotlight bulbs to help achieve the desired low level of lighting - for best results, always upgrade your dimmer switch to a purpose-built LED dimmer switch, capable of controlling the associated lower power levels (ordinary dimmer switches may deliver mixed results). Browse dimmable LED spotlights here. However, if you wish to retrofit your existing downlight solutions with efficient low wattage LED spotlight bulbs that you do not intend to be controlled by a dimmer switch, you may wish to browse non-dimmable LED spotlights.
Depending on the floor space of the area that you plan to illuminate, and depending on your desired level of cross over between beams, you may wish to consider different beam angles, including 36° beam LED spotlight bulbs, 100° beam LED spotlight bulbs, and 110° beam LED spotlight bulbs.
GU10 describes a twist-lock cap commonly used on mains-voltage spotlights. MR16 describes a reflector size; many MR16 lamps use a GU5.3 two-pin cap and a 12V supply. Check the cap and rated voltage on the actual product, as these lamps are not interchangeable.
Use the old LED lamp's wattage as a starting point, then compare lumens and beam angle. When replacing halogen, check the manufacturer's replacement rating rather than buying an LED with the same wattage.
A narrow beam concentrates light on a smaller area, useful for highlighting. A wide beam spreads light more broadly. The result also depends on mounting height, spacing and lumen output; match the existing beam angle if you want a similar effect.
No. Check the product's dimmable specification and the dimmer manufacturer's compatibility guidance. For low-voltage lamps, the power supply must also be suitable for the lamp and dimming system.
Check the individual product's contents. Some fittings take a separate replaceable lamp, while integrated LED downlights have a built-in light source. Verify the required cap, dimensions and any separately supplied components.
