The LUMii DIGITA Ballast is a fully electronic ballast, available in 600w (dimmable to 250 and 400w) and 1000w (dimmable to 400 and 600w). This technology is micro-processor controlled and works at higher frequency (hertz) than the standard magnetic ballast meaning more light gets to your plants. It is also more efficient meaning more output per watt of energy consumed. The LUMii DIGITA Ballast is dimmable and also has a boost setting for each lamp size meaning you can take control of the light output. The LUMii DIGITA ballast is one of the quietest on the market, with no hum or vibration. It is also one of the smallest and coolest running ballasts available. The LUMii DIGITA is very lightweight, a 600w is only 3kg, compared with 8kg for a 600w magnetic ballast. The LUMii DIGITA ballasts have safety features built in that protects the units circuitry if a short is detected. When the ballast detects an abnormal input or output voltage due to an old or damaged lamp, it will not attempt to ignite the bulb. The LUMii DIGITA ballast is resin covered on the inside, helping to protect from dust ingress to the components and creating even heat distribution, meaning there is no fan. How does the dimmer switch work? The dimmable features on the LUMii DIGITA ballast gives the user the ability to control the light output using the phase controller. The dimmable has 4 settings, including a boost setting, giving the user great control. For best results, use the correct lamp per wattage setting.

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.
