Light bulbs

First, think about the base type. Common sizes include E27 and E14 screw bases, as well as bayonet B22 fittings. If your fixtures use GU10 or MR16 sockets, search for GU10 bulbs or halogen replacements that still offer strong brightness in a shorter form factor. Next, consider lumens versus watts. A higher lumen count means brighter light, while a lower wattage keeps energy use down. For energy savings, prioritize LED light bulbs that deliver the same brightness with a fraction of the energy as traditional incandescent bulbs.

Color temperature matters for atmosphere. Warm white (around 2700K-3000K) creates cozy living areas, while cool white (3500K-4500K) or daylight bulbs (5000K-6500K) help with focused tasks and reading. If you value accurate colour rendering for artwork or textiles, look for a higher CRI rating. And if you want to adjust brightness without changing bulbs, choose dimmable bulbs or smart bulbs compatible with voice assistants and schedules.

Smart lighting lets you control scenes, schedules, and energy use from your phone or a home hub. Our range includes smart LED bulbs and starter kits that work with popular ecosystems, plus wireless bulbs that respond to apps, Bluetooth, or Wi‑Fi. For outdoor spaces, look for weather-resistant and long-lasting options designed to withstand the UK climate while still offering vibrant illumination.

Finally, consider practicality: are you replacing bulbs frequently? If so, prioritize long-life LED bulbs with 15,000–25,000 hours of service. If you’re outfitting a high-traffic area or a workspace, select robust, high-CRI, high-lumen options for clear, comfortable lighting every day.

LED bulbs dominate current demand due to efficiency, longevity, and versatility. They come in many bases (E27, E14, GU10, B22) and colors, from warm to cool, with dimmable and smart variants. Smart LED bulbs connect to apps and assistants, enabling scenes and schedules that suit busy homes. CFL bulbs provide an economical option for older fixtures without compromising much on energy savings, though they are gradually being replaced by LEDs for longer life and instant full brightness. Incandescent bulbs offer familiar warm glow but consume more energy and have shorter lifespans, while halogen bulbs provide bright, crisp light in compact forms. For specialty needs, consider reflector bulbs like BR30 or GU10 spots for kitchens and lounges.

Outdoor lighting benefits from weatherproof, high-lumen options, including LED flood bulbs and low-energy landscape bulbs with durable finishes. If you’re hunting for consistent daylight feel for workspaces or studios, choose cool daylight LED options with high CRI for vibrant colours and clarity.

Maintenance is simple but important for safety and performance. Handle bulbs carefully, especially when installing LED and fluorescent types. Store spare bulbs in their original packaging to protect them from impact. When a bulb fails, replace it promptly to avoid dimming or uneven lighting in rooms. For disposal, follow local recycling guidelines, many LEDs and CFLs contain materials that should be recycled rather than discarded with general waste. Regularly check fixtures for signs of overheating, discoloration, or flickering, and replace with bulbs of the same base and compatible dimming or smart controls to preserve stability.

What’s the difference between LED and incandescent bulbs?

LED bulbs use far less energy to produce the same brightness as traditional incandescent bulbs and last much longer, making them a cost-effective option over time. They generate less heat and are available in a wide range of colour temperatures and base types. For most homes, LED bulbs are the preferred choice for energy efficiency and longevity.

Are LED bulbs compatible with smart home systems?

Many LED bulbs are available as smart bulbs that connect to Wi‑Fi or Bluetooth. They can be controlled via apps or voice assistants, set schedules, and integrate with scenes. If compatibility is important, check the bulb’s standards (e.g., Zigbee, Matter) and ensure your hub or speaker supports the bulb type you choose.

What colour temperature should I choose for different rooms?

For living rooms and bedrooms, warm white (2700K–3000K) creates a cosy, inviting feel. Kitchens and workspaces benefit from neutral to cool white (3500K–4500K) for clear task lighting. Bathrooms often use bright white or daylight (4000K–6500K) for clarity and makeup or grooming tasks. Always consider the room’s function and your personal preference when selecting temperature.

Do I need dimmable bulbs?

If your fixture includes a dimmer switch or you want adjustable mood lighting, choose dimmable lights. Ensure the bulbs are compatible with your dimmer type (trailing-edge or leading-edge) to avoid flicker or buzzing. Dimmable LEDs give you flexibility without sacrificing efficiency.

How many lumens do I need?

Brightness is measured in lumens. For general room lighting, you’ll typically want 150–300 lumens per square metre, depending on the room’s purpose and the existing light. Task lighting may require higher lux levels, while ambient lighting can be softer. In practice, combine multiple light sources and choose bulbs with appropriate lumen outputs for layered lighting.

Where can I find the best deals on light bulbs?

Wowcher UK regularly offers discounts on light bulbs, including multi-packs, energy-efficient LEDs, and smart lighting kits. Look for seasonal promotions and bundles that include base adapters, dimmers, and compatible accessories to maximise savings and simplify upgrades across your home.
