Can you use a 400W high pressure sodium bulb in a metal halide ballast?
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
Can you use a sodium lamp in a mercury ballast?
No you can't. You can use a metal halide lamp of the exact wattage of the original mercury lamp. You cannot vary on wattage at all.
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).
Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
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.
Can you use 250W metal halide bulb in a 1000W metal halide ballast?
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
Can you use a 70 watt metal halide lamp in a 150 watt ballast?
Yes assuming the ballast is also for a metal halide lamp.
What type of a ballast do compact fluorescent lamps use?
a compact electronic ballast in the base of the lamp
Can you use a 400W high pressure sodium bulb in a metal halide ballast?
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
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
Can i use a probe start lamp with a pulse start ballast?
yes
Can i use a pulse start lamp with a probe start ballast?
yes
How many amps does a 1000 watt ballast use?
To answer this question the voltage of the ballast must be stated and the type of lamp in the fixture.
Can you use a 100 watt metal halide bulb in a 150 watt lamp?
Not recommended. It would work but shorten lamp life and may cause risk of fire. However, if you just wanted to check a lamp was capable of striking it would be ok for a few minutes. I've done the opposite in the past and used a 150w lamp with a 100w ballast. Works, but not good for any of the components, including lamp.
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.
Can you use a sodium lamp in a mercury ballast?
No you can't. You can use a metal halide lamp of the exact wattage of the original mercury lamp. You cannot vary on wattage at all.
