LED Lighting Watts to Amps Calculator: Single-Phase and Three-Phase Loads
![Watts to Amps Calculator for LED Lighting [Guide]](https://gqlamp.com/wp-content/uploads/2026/09/watts-to-amps-calculator-featured-768x512.png)
A watts to amps calculator is a tool for estimating LED lighting running current from input power, voltage and power factor; it requires more information than what’s filled in on a lighting quote form. The electrical supply voltage, the true…
Lumens vs Watts: How to Choose Brightness, Not Just Power
Updated August 2026 Lumens vs watts is a comparison between visible-light output and electrical power input. When replacing a common household lamp, find the required lumens first, then compare the watts used by products that deliver that output. With commercial…
Lux to Foot-Candles Converter: Formula, Chart, and Examples
Updated August 2026 Lux to foot candles is an illuminance unit conversion: multiply the lux value by 0.09290304. To convert in the other direction, multiply foot-candles by approximately 10.763910416709722. For example, 500 lx × 0.09290304 = 46.45152 fc. This conversion…
Watts to Kilowatts Converter: Formula, Chart, and Examples
Updated August 2026 Watts to kilowatts is a conversion between two units used to express power in the International System of Units. To convert watts to kilowatts, divide the watt value by 1,000. Example: 1,500 W ÷ 1,000 = 1.5…
What Is a Ballast? How a Fluorescent Light Ballast Works and When to Replace It
Updated August 2026 What is a ballast refers to an electrical ballast for lighting. It creates the conditions that a fluorescent or other gas-discharge lamp needs to start, then limits lamp current after the arc forms. It is not the…
