Producing a lime green shade of light this LED tube sleeve accessory is a great addition to locations that require a brightly coloured light source for both general lighting and effect lighting (note this product is a sleeve NOT LED tube). Simply slide the clear sleeve and lime green coloured insert over your 4 foot (1200mm) LED tube and then install your LED T8 tube again and voila! Instant lime green light. It has been designed to fit most brands of LED tubes however please check that yours is no larger than 32mm in diameter. It is also important to note that the lime green colouring has been matched to the Rosco lime green colour code of 088 making it possible to match up with existing sleeves if needed. Please note that this product is supplied as a clear plastic sleeve with a lime green coloured insert and that it requires both to function.
