At present, with the short supply of electric energy, and the increase of domestic consumption, the energy source is in great lacks .So that the energy saving requirement by the state is getting stricter. BESN direct current low pressure sodium ballast, operated in *4V direct current supply, can drive directly the low pressure sodium lamps of *8W&#****9;*6W&#****9;*5W&#****9;*6W&#****9;*5W&#****9;*6W&#****9;*0W&#****9;*1W. Generally, to drive the vapor discharge lamps and other high efficiency light source, power supply converting gear is indispensable, and the consumption is large. However, BESN electronic low pressure sodium ballast overcomes such disadvantages. solar garden lights : low pressure sodium lamp of *2V , *8W&#****9;*6W are available. solar sideway lights( 2m*4m in height): low pressure sodium lamp of *4V, *5W&#****9;*6W are available. solar street lights(5m*8m in height): low pressure sodium lamp of *4V, *5W&#****9;*6W are available. Solar high mast lights: low pressure sodium lamp of *4V, *0W&#****9;*1W are available. Tunnel lights: Low pressure sodium lamps from *5W to *0W, direct current or alternating current supply are available
