Solar Road Stud - Green; aluminium solar road stud with crystal LEDs and polycarbonate lens cover. Road studs, also called raised pav ement markers, Botts` dots, cat`s eyes, or road turtles are used for lane delineation, especially during the hours of darkness and adverse weather conditions. They delineate the roads at the centre and at the edges and mark the parking in car parks, traffic islands, and the entrances of shopping malls, gas stations and sites. Raised pavement markers ensure high visibility with cat’s eye or reflectors. Some studs are mounted with epoxy on the road surface, others are fixed with single or double shanks. Solar road studs are just like reflective road studs but use solar energy to power embedded LED lights. They are made of metal or durable tempered glass and can withstand a weight of ca.40 tons Technical Features Dimensions : 2,8 x 12,2 x 14,6 cm Material:  Aluminium, Polycarbon cover LED Color: red, yellow, white,  blue, green Weight :0,62 kg Photometric standard: EN 1463 ve BS 873 Installation :7,5 x 80 mm Buildex screws, 12 plastic fixing plugs Additional Information:  1x1800 mAh NiMh rechargeable battery, 2 x 1.5 V 100 mA solar panel,  4 x 5 mm crystal LED (bi-directional) GTIP: 9405.49.90.00.00
