Fluorescent U-Shaped Tubes
Like the T8 tube, U-Shaped tubes are 26mm in diameter and are often used for lighting large, wide-open spaces. They're normally seen in supermarkets, warehouses, garages and offices, although they're suitable for smaller environments that need plenty of light too. U-Shaped tubes offer excellent at colour rendering, so you can count on them to deliver the clarity and colour temperature you desire. They can also be used with specular reflectors to maximise their light output.
