Best Answer

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.

Can you use a 65 watt fluorescent bulb in a metal halide light fixture?

No, the ballast's output is not matched to operate a fluorescent bulb.


What is the comm wire on a ballast?

The white wire on the supply side. There isn't a common on the output side of the ballast.


How do you drop the 600-volt output power of a fluorescent ballast to use for an LED lamp?

You don't. The output of a ballast is for one purpose only and that is to operate the lamp that is designed for that ballast. You should be careful with high output ballasts as they can draw enough milliamps to lock your muscles up if the current is shorted through you.


If the ballast on a fluorescent light blows will the lamp still work?

If the ballast on a fluorescent light blows the lamp will not work.


Can a 32 watt tube work with 40 watt ballast?

The exact results are not normally documented in manufacturer's literature, because they do not condone purposely mis-matching ballasts and lamps That being said, if both are RAPID-START there is a likelyhood that the lamp will light with this ballast. The light output may be less than normal and the ballast may have a premature failure. It's not going to explode. If you are deperate, help yourself, but I would always recommend a correct match...


Does a tube light glow without starter?

yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.


How can you attach a 120 v Light Fixture to a 277 v system do I need a ballast so what kinda of ballast?

need a universal voltage ballast 120/277 volt or a 277volt ballast


Can T8 LED tube light be used with ballast and can ballast be removed and will it work?

A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.


How much power is consumed by a tube light?

One has to specify the size and therefore the watt usage of each type or the light output desired to compare them. Fluorescent tube lights range from 5 to 80 watts including losses in the ballast. Compact fluorescent bulbs range from 7 to over 30 watts in usage with the included ballast. LED's don't have nearly the same light output each, so you need a bunch of them to match output, but if matched use lower wattage because of low heat loss. Once you define the wattage, the total power is in watt-hours or kilowatt hours or some other conversion value.


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.


Why does a circular fluorescent light bulb not light up fully?

You have a failing bulb or ballast.
