400w Sunmaster Dual Spec HPS Lamp The 400w Sunmaster Dual Spec HPS Lamp has a lumen output of 55000 the majority of which is in the orange/red part of the spectrum, they also produce more blue that most other dual spectrum lamps making them ideal for vegetative growth and flowering. The Sunmaster range of lamps has proven to be excellent value for money providing reliability and quality time and time again. A horticultural lamp light output will decrease with use. We recommend that growers replace lamps at regular intervals to maintain optimum yields. As soon as lamps are switched on, they will run extremely hot. Before handling, lamps should be turned off the ballast disconnected and allowed to cool down. All high-pressure sodium and metal halide lamps need to be handled with care, avoid touching the lamp and particular care should be taken when using sprays or liquids around hot lamps as this may cause failure or explosion. 400w Maxibright iPac Magnetic Ballast The 400w Maxibright iPac Magnetic Ballast is a quality vented metal cased ballast that is used start up and power a 400 Watt HPS or MH lamp by using a traditional magnetic core and coil system alongside a Smart digital igniter. Maxibright’s high-quality, safe circuitry means that the Maxibright iPac Ballast will not restart a hot or faulty lamp and the built in thermal cut out also means that the ballast will shut down safely if it overheats. The 400w Maxibright iPac Magnetic Ballast is built to last, and is covered by a massive 25-year guarantee! Please note – Ballasts run warm so should be located on a firm flat surface (not carpet) in a well-ventilated area. To operate safely, the wattage of any lamps used should match that of the ballast. Maxibright Supernova Reflector The Maxibright Supernova Reflector is a parabolic aluminium design, this style of reflector is often referred to as a closed-end reflector, meaning that HID lamps are surrounded on all sides by reflector walls forcing all light to be reflected downwards towards plants. Photometric laboratory testing has shown that this style of reflector can increase light intensity by up to 50% compared to an open design. The Maxibright Supernova Reflector is popular with growers because of its high-quality construction and its ability to increase yields compared with a standard Euro Reflector. The closed-end reflector has a highly reflective dimpled surface area, which allows light to be reflected evenly to give a uniform spread of light with fewer hot spots. The ceramic lamp holder provided is heat resistant and is positioned to mount lamps horizontally.
