| While the long, slender proportions of the original Linear Fluorescent lamps makes them ideal for many applications, it can be a hindrance in others. A decade after the commercialisation of fluorescent technology and the refinement of the basic range, efforts were diverted into reducing the size of the light source. At first this was achieved by folding the standard tubes into various planar geometries - such as the circular, U-tube and W-shaped patterns featured on this page. Later still, improvements in phosphor technology permitted a considerable reduction in the diameter of the discharge tube, and that spurred the development of the third category of this lamp technology - the Compact Fluorescent lamps. |
