This Deep Amber coloured sleeve cover has been cut specifically to fit with 4 foot (1200mm) long 32mm diameter LED tubes. It will adjust the colour of the light output and is simple to install by sliding the clear sleeve and coloured insert over the tube. The deep amber shade has been made to the Rosco colour code 104. Using specific colour codes allows for products to be matched up or recreated at a later stage if required. Please be aware that this product comes as a clear tube with a deep amber coloured insert and requires both together in order to function.
