 Can I save energy converting to an electronic system?
 Yes. High Frequency Electronic ballasts will give an equal light output as magnetic, and consume 15-30% less power. |
What is meant by "High Power Factor" ballast?
Ballast designated High Power Factor (HPF) must have a power of 90% (0.90) or greater. Ballast factors lower than a 0.90 are called Normal Power Factor. |
Is a HF ballast more efficient than a NPF Ballast?
Yes, but only in terms of how well it uses the apparent power ( volt-amperes), not the metered power (watts). Remember that the user pays for watts, not volt-amperes. Therefore, if the wattage ratings are the same for both the HPF and NPF units, then the user will not see a difference in the electric bill. However, if the userís electric rate includes a low power factor penalty and if enough NPF units are in use, there may be an increase in the electric bill. The other issue concerns circuiting, Use of HPF ballast will allow more fixtures per circuit. |
Can we operate 2 pin compact lamps?
No, there is a starter in the base of 2 pin compact lamps for magnetic operations only. |
The lamp has only a dim glow, What could be the problem?
Bad connection, bad socket connection and check all connections. |
My lamps are blacking prematurely, is there a problem?
End blackening is a normal function as lamps age, provided the blackening is even. Early blackening may be a heat related issue in your fixture. |
Why are my lights blinking?
As you may know it has recently been discovered that compact lamps as they age can operate at 3 to 5 times their rated power. This huge increase in power can have negative effects on fixture components including ballast. Fulham has installed a lamp alert feature into the WH2-120-L/C, WH3-120-L/C, WH22-120-L/C and WH33-120-L/C products. These products are those in our current product line that are used to drive compact fluorescent lamps. Lamp alert provides the user with a visual indication that the lamp is operating at these extremely high power levels allowing the lamp to flash at a one to two second interval. It also limits the maximum power drawn by the ballast to a level that is between 150 to 200% of nominal ballast power thereby reducing the stress on the ballast and other fixture components. |
