A ballast is effectively a transformer which boosts the supply of electricity flowing to your grow lamp. They are an essential part of any High Intensity Discharge (HID) lighting system and come in two varieties: magnetic or digital.

Magnetic ballasts (such as the Corona Hobby Ballast) are usually cheaper and are a great choice for entry level growers or those buying multiple units. Whilst still providing excellent results, magnetic ballasts tend to create more heat and noise than their digital counterparts.

Digital ballasts, by contrast, produce very low levels of heat and noise – and therefore tend to be more efficient when using electricity. Some of these ballasts are also dimmable, meaning you can alter the output of your lamps to meet the needs of your plants/environment.

Whichever ballast you choose to go for, you can be sure that you are buying a high-quality piece of equipment. If you have any further queries or questions then do not hesitate to contact us via email, over the phone or in person at our central South West London store.
