CASE STUDY 1
Magnetic Ballast vs. Electronic Ballast
Following Ontario's standard for retrofit lighting, we'll be replacing 400W HPS/MH HID magnetic ballasts with 250W HPS/MH HID electronic ballasts. For this example, we will assume the lights are running 24 hours a day.
To keep a magnetic ballast running at full power (400W), with efficiency only at 80%, we require 562.5W.
To keep Noctex's electronic ballast running at full power (400W), with efficiency at 94%, we require 265.W.
Now onto a few simple calculations:
562.5W - 265.6W =
296.9W (saved per hour)
296.W x 24hours =
7125.6W (saved per day)
Therefore, 7.1256 KW/h is saved per day.
7.1256 x 365 (days) =
