• These state-of-the-art ballasts are manufactured to provide today’s serious grower with maximum flexibility & performance. The Galaxy® Select-A-Watt™ is the preferred “dimmable” electronic ballast on the market. The Galaxy® brand name carries a strong reputation of reliability and performance.
• Lamps are only dimmable on wattages lower than the specified lamp wattage. A 1000 watt lamp can be dimmed down to 600 or 400 watt. A 600 watt lamp can be dimmed down to 400 watt, but cannot be over-driven to 1000 watts.
• Turbo Charge is designed for 1000 watt lamps only on 902518 and 600 watt lamps only on 902517. Do not use with 400 or 600 watt lamps on 902518 and do not use 400 watt lamps on 902517. This can be hazardous.
• There are three ways to use the Select-A-Watt™ feature: It will properly drive a 400, 600 or 1000 watt lamp to ANSI specifications. For example: Set the switch to 400 watts, insert a 400 watt lamp into your socket and the ballast will operate the 400 watt lamp. The ballast will similarly operate 600 or 1000 watt lamps.
• The second option is to dim a 1000 watt lamp. Adjust the switch to 400 or 600 watts and the ballast will dim the 1000 watt lamp by 40% or 60%.
• The Turbo Charge feature will increase the output of a 1000 watt lamp (only) by approximately 10%. You will achieve peak performance, but this may decrease your lamp life.
• 5 year warranty.
