Can you use a 70 watt high pressure sodium bulb in a 100 watt ballast?
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
Will a higher wattage hps bulb work in a ballast that came with a lower wattage bulb?
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
What wattage of bulb do you need to fit in a socket that has 120volts?
120 volts is a standard voltage in US for normal house hold electric outlet. , So you can buy from 0 watts to 1000 watts for 120Volts socket . However the bulb you want to buy depend on the Lamp holder , rating of the socket and where the holder is installed, how much light you need etc . Check the max Watts rating on your socket or Lamp and determine the correct Wattage bulb to use. No one can tell you what wattage bulb to use with out looking at your socket or Lamp. The formula for Watts = Volts x Amps Check out the low wattage Compact Fluorescent Light Bulbs which will consume very low engergy and save money in a long run http://www.energystar.gov/index.cfm?c=cfls.pr_cfls
How much energy does a projector use?
The power rating is printed on the lamp holder, expressed in watts. As power describes the rate of energy consumption, you need to convert the number of watts into kilowatts (divide by 1000) and multiply this figure by the time for which the lamp is in use (expressed in hours) -this will tell you the number of kilowatt hours of energy used.
How do you replace ac ballast where emergency ballast present?
First you need to determine if it's the ballast that's bad or the emergency ballast. The emergency ballast can go bad and cause the bulbs not to work or not all of them to work depending on the lights wiring setup. Push the test button on the emergency ballast which should have a red glowing indicator light. If all the lights illuminate slightly, change the emergency ballast. It's best to buy the exact ballast for this repair. i.e. If it's a T8 3 lamp fixture. Buy a T8 3 lamp ballast not a 4. You can use a 4 in place of a 3 lamp, but the 3 lamp will be more user friendly. Easiest way is to note what wires go to what. Draw a diagram if you have to and just simply match them back up.
Do you need a ballast for HPS lights?
Yes, a ballast is required for HPS (high-pressure sodium) lights. The ballast helps regulate the electrical current and provides the initial high voltage needed to start the lamp. Without a ballast, the HPS light would not function properly.
How can you find out what type of ballast you have if it has no marks on it?
ballast are either electronic or iron core induction type so at the end of the day it does not matter what type it is so long as it can handle the wattage of the tube you are trying to drive any thing will work so long as you have every thing in place that the new ballast needs,electronic types need nothing to work ballast types need a starter of some kind
Can we use a fluorescent lamp in DC?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.

Can you use T12 lamp holders with T8 lamps when you change to T8 ballast?
Absolutely. Only you need connect together two wires coming from each lamp holder (shunt).
Can you use a smaller watt bulb in a bigger fixture will it run at bulb watt or fixture watt?
Yes, because the "higher" watt energy saver bulb (cfl) is actually a lower watt bulb than a standard (incandescent). Always look at the actual watts, not the 'light equivalent watts'. 11 watt low energy tube = 60 watts of old-fashioned light. More light, less heat!
What is the output of a light ballast?
Fluorescent electronic ballasts have a voltage to amperage ratio chart on their face. Use this chart by selecting the voltage you are using and the corresponding amperage, then multiply the two numbers together for your wattage. Some fixtures come with more than one ballast, so you will need to take the wattage of all applicable ballasts for any given fixture to obtain the total wattage for the fixture.
