MH grow lamps
(metal halide) are a popular lighting choice among indoor gardeners because they have the ability to produce more vegetation. We carry 250-watt, 400-watt, 600-watt and 1,000-watt bulbs from top brands including Sylvania and Plantmax. Life hours range from 6,000 to 20,000 hours and are available in universal or horizontal burn position.
While metal halide grow lighting isn’t the least expensive lighting option available, it’s often the best choice when a high intensity discharge (HID) is desired. Metal halide lamps work through a design incorporating a bulb within a bulb. An arc tube inside a larger bulb causes halides inside the bulb to glow with extreme intensity, emitting a remarkable amount of light with very little energy use.
Metal halide replacement bulbs also function for quite a long time — 20,000 hours or more in many cases. Although there is some upfront cost, metal halide bulbs do pay for themselves over time, especially when you require the best lights on the market for your gardening project.
