Made especially for 1200mm (4 foot) LED T8 tubes this beautiful sleeve accessory is a brilliant option for changing the appearance of your space using light. The 32mm diameter allows it to be installed over most brands of LED T8 tubes (please check that your tube is no more than 32mm in diameter) and is very simple to install. Start by removing your current LED T8 tube slide the colour insert and clear sleeve section over and then reinstall the LED tube. Once installed it will alter the light colour to the aforementioned steel blue colour which has a Rosco code of 117 making it possible to match up to existing sleeves at a later date. Please note that this product does not come with end caps and does not require them. Not suitable for T8 or T12 fluorescent tubes.
