What Voltage Is Metal Halide?

Metal halide lighting is in many ways optimal for fish tanks. Besides being versatile, they offer more lumens per watt than any other artificial light source. They also last longer than conventional incandescent bulbs.

  1. Voltage

    • The voltage is a measure of electric potential; volts drive electrical current through a closed circuit, and one volt can push one ampere through a resistance of one ohm.

    Check the Box

    • Commonly, manufactures label bulbs and/or boxes with the voltage, wattage and amperage.

    WAV Formula

    • If you know the amount of amps and the amount of watts, apply the "WAV" formula of: Watts = Volts x Amps. To calculate Volts, simply invert the formula: Volts = Watts / Amps.

    Use a Volt Meter

    • There is a way, however, to directly measure volts by means of a voltmeter.
