Events parties and gatherings can be totally transformed with the change of lighting colour. This fantastic LED T8 sleeve accessory is the ideal economic solution to create a whole new feel to your space as it uses your existing lighting. Simply uninstall your current 1200mm LED tube from its fitting slide over the clear sleeve with its Deep Straw insert and then reinstall the LED tube. Once activated it will then output a slightly dimmer yellow coloured light. The shade of yellow is Rosco colour 015 making it possible to match up to existing sleeves. Please note that this product comes in 2 parts as a clear sleeve and a coloured insert both pieces are needed for it to hold together.
