Frequently Asked Questions

Q: What wattage CFL bulb should I choose – 18W, 24W, or 36W?

A: Your choice depends on your fixture's specifications and desired brightness. The 18W bulb (22 cm) is suited to smaller enclosed luminaires, the 24W (32 cm) works well for medium fixtures, and the 36W (42 cm) delivers the most light output for larger spaces such as offices or workshops. Always check your fixture's maximum wattage rating before purchasing.

Q: Is this CFL bulb compatible with my existing fitting?

A: This bulb uses a standard 4-pin base, which is common in recessed downlights, office luminaires, and enclosed ceiling fixtures. Before ordering, verify that your fixture accepts a 4-pin H-tube twin CFL and check the size (A1/A2/A3) against your fixture's tube length requirement.

Q: How long can I expect this CFL bulb to last?

A: Compact fluorescent lamps are designed for extended operational life — typically far longer than conventional incandescent bulbs. For best longevity, avoid frequent short on/off cycles and ensure the bulb is used within a compatible, well-ventilated fixture.
