Digital Ballasts and Analog Ballasts The key component to take into consideration when buying a conversion kit is whether to choose a digital ballast or an analog ballast. The pros and cons of analog versus digital are very similar to the pros and cons of DC versus AC power. With that said there are some […]
A high-intensity discharge lamp, also called an HID lamp, is a light bulb that produces light with an electrical discharge. To do this, an arc of electricity is required between two electrodes made of tungsten. These are contained inside either semi-transparent or transparent quartz. It is filled with a mixture of gas and metal salts. […]
High intensity discharge (HID) lighting, by definition, has high levels of electrical discharge, to create an electrical arc in the bulb, which emits light. Supplying the power to create, drive, and sustain this arc reliably is no easy feat. The device that does this is called a ballast. It is a complex circuit made up […]
