Ceramic Metal Halide Grow Light Ballasts

A Ceramic Metal Halide Grow Light Ballast functions to start and regulate the current inside a CMH grow light. If the current is not regulated, there is a risk of your CMH bulb burning so bright that it ends up "popping." It may also not be able to start at all.

With the help of ballast, your bulb conveniently completes its standard life span, in this instance, up to 24,000 hours. The ballast helps maintain the bulb's brightness even when it starts losing its intensity.

How do I choose the right CMH ballast?

Among the different options available, digital CMH bulbs are the most suitable. They can function with 30% higher efficiency as compared to magnetic ballasts. These ballasts also occupy lesser space and produce much lesser heat. The digital ballasts also come with a dimmable function that allows you to exercise more control over your grow room's light intensity. This way, you can regulate wattage and use your grow lights with higher efficiency.

At Groindoor.com, you can get all sorts of CMH ballasts, including a standard 120 supply volt or 240-volt, or 277-volt options that are more suitable for commercial grows.

Here's an expert tip for you. When you select your CMH ballast, you should consider the wattage of your CMH grow light because it should match the wattage of your CMH ballast. It is possible to use a single-ended CMH bulb with a double-ended CMH ballast, but the opposite doesn't work. For a double-ended CMH grow light, you need to have a CMH ballast that is optimized for double-ended bulbs.
