1. What are LED light bulbs?
LED light bulbs are modern, energy-efficient alternatives to traditional incandescent and halogen bulbs. They use light-emitting diodes (LEDs) to produce bright, long-lasting illumination while consuming a fraction of the energy. Available in many shapes, sizes, and colour temperatures, LED bulbs can be used in almost any indoor or outdoor fitting, making them a versatile choice for both homes and businesses in Ireland.
2. Can I replace halogen bulbs with LED bulbs?
Yes, in most cases you can replace halogen bulbs with LED bulbs directly, as many LED models are designed to match the shape, base type, and voltage of standard halogen lamps. However, some fittings may have dimmer switches or transformers that are not compatible with LEDs, so it’s important to check specifications before replacing. Using LED bulbs instead of halogen offers immediate energy savings and longer life.
3. Can LED bulbs be dimmed?
Many LED bulbs are dimmable, but not all. To ensure smooth performance, you need to use a compatible dimmer switch designed for LED technology. Using a non-LED dimmer can cause flickering or buzzing. Always check the packaging or product details to confirm whether the bulb is dimmable and, if necessary, upgrade your dimmer to an LED-compatible model.
4. Where can I buy LED light bulbs in Ireland?
You can buy LED light bulbs online in Ireland from reputable lighting suppliers offering a wide selection of shapes, wattages, and fittings. Online shops often provide detailed specifications, fast delivery, and better pricing compared to physical stores. When purchasing, look for CE-certified products with clear lumen output and colour temperature information to ensure quality and reliability.
5. How many watts are required for an LED bulb to light a room?
The required wattage for LED bulbs depends on the size of the room and the desired brightness. As a general guide:
- 4–6 W for small spaces (≈ 400–600 lumens)
- 8–12 W for medium rooms (≈ 800–1,200 lumens)
- 15 W+ for large rooms or high ceilings (≈ 1,500+ lumens)
Unlike halogen, LED brightness is measured in lumens rather than just watts, so always check both to choose the right light level.
