In the 1970s, Thorn Lighting introduced an energy-saving 8 ft retrofit tube in Europe. Designed to run on the existing 125 W (240 V) series ballast but with a different gas fill and operating voltage, the tube operated at only 100 W. Increased efficiency meant that the tube produced only 9% lumen reduction for a 20% power reduction. [ 7 ]

Artificial turf with rubber crumb infill Side view of artificial turf Diagram of the structure of modern artificial turf Artificial turf square mats. Artificial turf is a surface of synthetic fibers made to look like natural grass, used in sports arenas, residential lawns and commercial applications that traditionally use grass.
Each square foot of turf contains about 3 kg (7 lb) of sand and 1.5 kg (3 lb) of cryogenic rubber. FieldTurf does not use shock-absorbency pads below its infill. The backing of the turf is a combination of woven and nonwoven polypropylene. These materials are permeable and allow water to drain through the backing itself. [8]
Essentially the existing turf is removed to a depth of typically 40 mm turf and 110 mm of soil. The replacement turf is ideally purpose grown to ensure consistency and freedom from weeds. A pitch can usually be returfed within four days and would typically involve removing and relaying 400 cubic metres of turf and soil.
AstroTurf is an American subsidiary of SportGroup that produces artificial turf for playing surfaces in sports. The original AstroTurf product was a short-pile synthetic turf invented in 1965 by Monsanto. [2] Since the early 2000s, AstroTurf has marketed taller pile systems that use infill materials to better replicate natural turf. [3]
