They are available in different diameters and wattages to suit various fitting types. Explore the full Fluorescent & Tube Lights range for more options.

Circular fluorescent tubes are available in different tube diameters (such as T5 and T9) and ring diameters. Always check the dimensions of your existing lamp or fitting before ordering to ensure compatibility. The wattage and pin base type also need to match your fixture.

If energy saving is a priority, consider whether an LED upgrade is possible for your fitting. Browse Compact Fluorescent Lamps for another efficient fluorescent option.
