This cool white coloured LED T8 tube light has been coated with a Our shatterproof protective sleeve/coating which is IEC 61549 compliant and is identified with a dual green band. The sleeve encompasses the tube making it essential for use in environments where you may be concerned about the possible costly consequences that a broken tube could cause.This 5ft LED T8 tube light bulb from Crompton Lamps replaces the mercury and other hazardous materials found in compact fluorescent tubes with modern LED components, making it a much safer, more reliable and more efficient alternative.The tubes linear circuit board is adorned with a series of SMD LED chips that sit within a protective, cylindrical glass shell. This use of glass - rather than plastic - prevents the tube from bending, warping or discolouring over time.The tube itself uses just 24W but delivers the same light output as a 58W compact fluorescent tube, within an optimal 320 beam angle.
