This lovely Magenta coloured sleeve cover is a great addition to your existing 4ft (1200mm) LED tubes to alter the light colour for parties gatherings and events. It is easy to install by simply removing your current LED tube slide the sleeve and coloured insert over the tube and reinstall. Not only is it a very simple way to create a whole new atmosphere but it is much cheaper and brighter than dedicated expensive RGB lighting. The Magenta colour of the sleeve is Rosco code 113 which can be used to match existing sleeves precisely. Please be aware that this product has no end caps and will not fit a T12 fluorescent tube. It is also worth noting that it comes as a clear plastic sleeve and a separate Magenta (113) coloured insert.
