Description

20w T4 fluorescent tube (warm white 578mm inc pins, 568mm excl pins) CHECK LENGTH CAREFULLY by Leyton Lighting product. This is a 20w T4 tube that is 578mm long including the pins at each end and 568 mm long excluding pins with a tolerance +/- 2mm. It is used in under cupboard lights and some illuminated mirrors. 3400K (warm white) Please double check length of this tube before ordering as some manufacturers have different T4 tube lengths, despite having the same wattage. These tubes from Leyton Lighting have plastic end caps that can be removed. This makes the tube slightly shorter which can help with installation into some brands of light fitting. T4 fluorescent fittings have been discontinued since 2015 due to EU regulations. The electronics are located in the light fitting and not the tube. If you are finding your lamps are not lasting as long as expected, this would indicate a fault in the light fitting and not the tube - unless the tube is physically smashed it's very unlikely to have a fault. You can test tubes and fittings by swapping tube from another working fitting. Unfortunately manufacturers no longer provide a guarantee for T4 tubes, as the light fittings they are installed into may be approaching the end of their life.
