Q: How much electricity does a 400 watt metal halide use?

A: System watts are the total watts the lamp and the ballast use together. The system watts for a 400 watt metal halide is about 458 watts depending on the ballast. What is the difference between lamp watts and system watts?

Q: What is the Lux of a 400 watt metal halide?

A: The luminous efficacy of the typical MH bulb ranges between 65 to 80 lm/W. Depending on the manufacturer, the number can be even lower. In fact, you can find many 400W metal halide lamps that produce only 20,500 lm. This means that the lumen per watt ratio is 51 lm/W. Some commercial 1500 HID bulbs have a lumen per watt ratio of just 22 lm/watt.
