The Maxibright Varidrive 600w Air-Cooled Coolshade grow light has four adjustable power output settings (250w, 400w, 600w and 660w boost) for continuous flexibility during the whole growing and flowering cycles. Utilise space in your grow room without compromising on performance. The Varidrive ballast runs both high pressure sodium and metal halide bulbs.

Although the 600w Varidrive ballast does not have the same enhanced features as a Maxibright 600w Pro Select ballast (RF Protection, Dynamic Frequency Control etc) it is constructed with safety and reliability features that will ensure peace of mind usage.

The Coolshade reflector is available with either 120mm or 150mm flange (120mm overall dimensions: 120mm x 560mm incl ducting flanges – 150mm overall dimensions: 150cm x 560mm incl ducting flanges) for connection to ducting/an in-line fan. Coolshade’s are an air-tight, fully sealed clear glass tube with a lamp mounting bracket in its centre. It’s perfect for removing the excess heat generated by HID grow lights without leaking unpleasant odours.

Tip: A HID (HPS/Metal Halide/CDM) bulb will drop approx. 30% of its lumen output within 12-14 months of continuous use. We recommend replacing every 3-6months for optimum plant growth and yield output!

* PLEASE NOTE: We do not recommend dimming a 600w/400w/250w lamp down or up to a lower or higher setting. Please ensure that you are using the correct wattage lamp/bulb for the desired wattage setting on the Varidrive ballast. Always switch off your light, wait for your lamp to cool, remove and replace the lamp/bulb with one that matches the chosen dimmed wattage setting.
