For the amperage of a metal halide fixture look for the nameplate which can be found on the side of the ballast. There it will tell you what the amperage of the fixture draws. Knowing what one fixture draws will allow you to size the lighting circuit for wire and breaker sizes.

What is the formula to calculate ac current in single phase 240volts?
The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor). The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.
Why current will vary in a solar cell?
The current will of course vary with the intensity of the imparted light and with the temperature of the panel.
How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
A 100-w light bulb is turned on it has an operating voltage of 120 V how much current flows through the bulb?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Does more current flow into a light bulb than out of it?
No. Although there is a voltage drop across the filament of an incandescent light bulb, the amount of current flowing out is identical to what flows in: current in = current out. That is an important fact to always keep in mind when solving simple electrical circuits: the sum of the currents flowing into a node equals the sum of the currents flowing out of it.
Can you use 14-3 wire to power metal halide light outside?
The question isn't what you're powering with a particular gauge of wire, but what's the current draw. If the metal halide light can run on a 15 Amp breaker (from the breaker panel), fine use your metal halide in your residential application and run it on the 14 gauge wire.
What is the formula for calculating the full current load of a 400 watt light?
Assuming an incandescent bulb and a 120 volt supply the formula is Watts = Volts x Amps x Power Factor where PF = 1 for resistive load. Amps = 400 / 120.
Which light is brighter Metal Halide or mercury Vapor?
Between Metal Halide and Mercury Vapor the higher output is emitted from the Metal Halide lamp.
What does a metal halide light do to a plant?
Metal-halide light is helpful for plant growth and is often used for indoor plant growing applications. Metal-halide lights produce blue-frequency light. They can provide the temperature , as well as the spectrum of light that encourages plant growth.
Is halide granules being activated by light a chemical change?
no
When photographic film is exposed to light the salt on the film breaks down what metal is formed?
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
When photographic film is exposed to light what metal is formed?
silver halide
What metal in the form of a halide salt is responsible for the sensitivity of photographic film to light?
silver.
What metal in the form of halide salt is responsible for the sensitivity of photograhic film to light?
silver
What is a compound used in photography which darkens when exposed to light?
Silver Halide Silver iodide
What part of the silver halide crystal is most affected by light when film is exposed?
The part of the silver halide crystal that is most affected by light when film is exposed is the surface. More specifically, any sensitivity specks that can become metallic silver.
Is energy equivalent to mass?
By Newton's law - NO -------------------- Einstein's famous formula states that energy is equivalent to mass times the speed of light squared.
