How much power does a mercury vapor light use?
Compared with newer HID lighting, mercury vapor isn’t very energy efficient. The “efficacy”—or amount of light produced per unit of electricity consumed—is 20-60 lumens per watt. This is better than incandescent lamps (about 15-20 lumens per watt), but significantly lower than other HID lighting.
Can you use a LED bulb in a metal halide fixture?
Light-emitting diode (LED) technology advancements now allow you to retrofit your metal halide lamps with a simple bulb change. LEDs can give you comparable lumens at a fraction of the energy cost. They are also longer-lived and show a lower reduction of performance over their service life.
What is the difference between mercury vapor and metal halide?
There is no difference between metal halide and multi vapor lamps because both names describe the same form of lamp. Metal halide or multi vapor lamps are a form of the light source that creates light via passing an electric arc through a gaseous mixture of mercury vapor and vapor of some metal halides.
Do mercury vapor bulbs burn out?
Mercury vapor lamps have rapid lumen depreciation and continue to burn on but never burn out. … If you’re looking to replace a mercury vapor lamp, they can typically be replaced with a metal halide or pulse start metal halide luminaire using significantly less energy.
Do mercury vapor lights get hot?
Mercury vapor and halogen lamps are generally used as basking lights. For the most part, they direct heat into a small area. But they get hotter than incandescent basking bulbs.
How many lumens is a mercury vapor bulb?
Mercury vapor lamps are more energy efficient than incandescent and most fluorescent lights, with luminous efficacies of 35 to 65 lumens/watt. Their other advantages are a long bulb lifetime in the range of 24,000 hours and a high intensity, clear white light output.
