Sunlight Supply's The Sun System VI Switchable plant light ballast allows the use of either a 400W metal halide or a 400W HPS lamp. To change lamps, insert the appropriate lamp and set the switch to the correct operating setting. This enables growers to utilize the proper spectrums for vegetable growth (metal halide) as well as flowering (high pressure sodium) with a simple to use switch. This switchable ballast has a cool wall separator and louvered end plates for maximum efficiency and cooling. The aluminum heat sync ballast enclosure also ensures cool, quiet operation. The heavy duty key-way handle allows wall mounting this switchable ballast. Includes 6ft. power cord, 15ft. lamp cord and 5kv mogul socket assembly. Add optional integrated intermatic timer to this 400 Watt Switchable ballast. Purchase reflector and 400W HPS & 400W Metal Halide bulbs separately. Save when you buy a complete 400 Watt Switchable grow light system that includes reflector, bulb and 400 Watt Switchable ballast.
