Sector T4 Tubes (Warm White) are called T4 because they measure four eighths of an inch in diameter, about 12.5mm they normally have metal end caps unlike other T4 tubes that usually have plastic end caps.
The measurements DO NOT include the pins
They have been used for kitchen lights, bookcase lights, cabinet lights and anywhere a small fitting is required.
If you don’t see the tube you want then please get in touch as we may be able to help
Sadly the light fittings themselves are no longer being made and we are now out of stock.
