Sliwo Lighting Co., Ltd. - DC electronic ballast,DC lighting fixture

dc input fluorescent lamp ballast for solar lighting dc ballast dc lighting fixture for industry control lighting 12vdc dc input fluorescent lamp ballast for solar lighting 12VDC electronic ballast dc energy saving lamp bulb Compact Fluorescent Lamp CFL 2U,3U,4U shapes, Globe Shape, 5W-30W ------------------------------ SLiWO designed a very high efficient line of electronic ballasted 12 V DC compact fluorescent lamp (CFL). Preheating, high electronic efficiency and low thermal losses increase the lifetime of the CFL to more than 100.000 on / off switching cycles. The SLiWO CFLs show much higher lumen efficiencies (lm/W) compared to LED or incandescent lamps. Features : *brightness comparable with an incandescent bulb using 5 times its eletricity; For exmaple, light output of an 11 W CFL is comparable with a 60 W incandescent bulb * saves up to 80 % of energy compared to an incandescent bulb * high reliabilty of more than 100.000 on / off switching cycles * 8000 Hours reliable operatio,several years of operation in the field * easy to install by a E27 or bayonet B22 socket * compact & robust product design ------------------------- 12 VDC High Efficient Electronic Ballast for solar lighting systems For T4,T5,T8,T9,T10,T12 fluorescent bulbs or PL CFL bulbs, 4W-40W ------------------------ SLiWO manufactures DC inverter ballasts with IC control circuit. Two transistors with the controlling IC push-pull switching changes the low voltage DC source into high voltage, sinusoidal AC power (20-30khz) to start and operate the fluorescent lamp. The ballast is inherently more efficient since the ballast output voltage is sufficient to start the lamp instantly and the lamp cathodes are not continuously supplied with power to keep them heated. Most suitable for solar lighting projects & OEM applications. Sepcifications : Input voltage: 12VDC (24 or 42vdc) Low Wattage: 5W~11W High Wattage: 13W~40W -------------------------- sliwo@yahoo.cn http://users4.nofeehost.com/sliwo ---------------------------
