How does dimming work in industrial applications?
Fluorescent fixtures can be wired with multiple circuits that can be switched to vary light levels, reducing energy costs. Because HID fixtures contain individual lamps, they do not offer this dimming method. Fluorescent lights can also be dimmed with a dimming ballast. In the case of HID fixtures, lights can only be dimmed to about 50 percent of their full output; even then, the dimming is not linear with the energy consumed, so in some cases very little energy is actually saved. How can I calculate energy savings with efficient industrial lighting? Use the energy savings calculator to determine the cost savings of switching from an HID system to a fluorescent lighting system in your workspace. You will need to know the annual burning hours of the system, the energy costs in your area, your estimated labor rate, if your system will be dimmed (% of time and brightness), fixture quantity, total wattage, and lamp cost.
