How are rapid start and programmed start ballasts different?
Rapid-start ballasts have a fixed “start sequence” where they preheat the filaments in each end of the tube. (that’s why each end has 2 pins, and 2 wires going to each end of the tube). They take a second to start, but are much easier on the tubes. Programmed-start ballasts have sensors to preheat the tube until it’s actually ready to start.
How much wattage does a ballast lose per second?
The frequency refers to the number of electrical pulses per second that the ballast consumes. A low-frequency ballast will use 120 pulses per second and will lose significantly less energy.
Are there any energy savings with instant start ballasts?
Many facilities have installed instant-start ballasts, in spite of the negative effect they have on lamp life. In promoting the use of instant-start ballasts, one manufacturer claims the energy savings of 1.5W per lamp more than compensates for the difference in lamp life. This manufacturer estimates it would take 35 years to pay back the savings.
Can a CFL be used as a ballast?
As a result, ballast designs for both compact fluorescent lamps (CFLs) and linear fluorescent lamps are becoming smaller and lighter. Fixture manufacturers are incorporating these designs into new products and new models of slim-profile indirect and direct-indirect fixtures. The efficiency of electronic fluorescent ballasts has also improved.

When to change magnetic ballasts to electronic ballasts?

What are the different types of CFL ballasts?
And there are two types of ballasts in each family: magnetic and electronic. Magnetic ballasts are the older ballast technology. For the fluorescent family, both T12 linear fluorescents and two-pin CFLs use magnetic ballasts.
Which is better OEM or aftermarket HID ballasts?
Though, there is a reasonable margin of quality between OEM-made and really cheap aftermarket HID kit ballasts; mostly in terms of long-term reliability. OEM ballasts also tend to warm the bulbs up to their full operating intensity a few seconds faster than aftermarket units.
