1. What is the best LED tube light?
The best LED tube light depends on where it will be used. For offices, schools, and shops, T8 LED tubes with high lumen output and neutral white light (around 4000 K) are ideal for bright, comfortable illumination. For energy savings and long lifespan, look for models with high efficacy (≥ 120 lm/W) and CE certification. Many businesses in Ireland prefer high-quality T8 or T5 LED tubes with instant start and flicker-free operation for both new installations and retrofits.
2. What does T5, T8, and T12 mean?
The letters T5, T8, and T12 refer to the diameter of the LED tube. The “T” stands for “tubular,” and the number indicates the diameter in eighths of an inch:
- T5 = 5/8 inch (16 mm)
- T8 = 8/8 inch (26 mm)
- T12 = 12/8 inch (38 mm)
T8 tubes are the most common replacement for fluorescent fittings in Ireland, offering a good balance between brightness, efficiency, and compatibility.
3. How to convert fluorescent tubes to LED?
To convert from fluorescent tubes to LED, first switch off the power and remove the old tubes and starter. Then install the new LED tube light fitting or retrofit the existing one according to the wiring diagram supplied by the manufacturer. Some LED tubes are direct replacement (plug & play), while others require bypass rewiring to remove the ballast. Always follow the specific instructions and, if needed, consult a qualified electrician.
4. Do you need a starter with LED tubes?
Most LED tube lights do not require a conventional starter. If your fitting uses magnetic ballasts, you might need a dummy starter (often supplied with the tube) to complete the circuit. In fittings with electronic ballasts, the ballast is usually bypassed during installation. Check the product label or manual to determine the correct setup for your LED tubes.
5. Where to buy LED tube lights in Ireland?
You can buy LED tube lights online in Ireland from reputable lighting suppliers offering CE-certified products, fast delivery, and warranty support. Online stores typically stock T5 and T8 LED tubes, suitable for commercial, industrial, and residential applications. When purchasing, compare lumen output, colour temperature, and installation type (plug & play vs. rewiring) to find the best option for your needs.
