When should I switch to HPS lights?

When should I switch to HPS lights?

Are metal halide lights dangerous?

Broken and unshielded high intensity metal halide and mercury vapor light bulbs continue to cause eye and skin injuries, particularly in school gymnasiums.

Do metal halide lamps need a ballast?

Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. MH lamp voltage typically increases over time, and the ballast must continue to provide sufficient voltage to the lamp as it ages.

How do metal halide lamps work?

To put it simply, metal halide technology works by passing an electrical arc through a mix of gasses, creating light. When the lamp is inactive, the mercury and metal halide salts are condensed inside the inner arc tube. Metal halide lighting features two electrodes –– one on each end of the inner arc tube.

How hot does a metal halide bulb get?

2000 degrees Fahrenheit

Why do metal halide bulbs explode?

It might be letting too much current — which would overheat// over pressurize the active component of the MH. So you have to be on the watch for that, too. Voltage spikes would produce the same heat surges, again, destroying the lamp.

How many lumens does a 175 watt metal halide put out?

What is the Lumen Output of a Metal Halide?

Do dusk to dawn lights use a lot of electricity?

Assumptions: Dusk-to-dawn lighting operates an average of 11 hours per night. Electricity at 14¢ per kWh.

Are dusk to dawn lights good?

Dusk to Dawn light fixtures are multi-use—you can put them anywhere and they are sure to do a good job. But, because their LED light technology, Dusk to Dawn light fixtures from Superior Lighting provide better light coverage than conventional light options and they last longer and consume less energy too.
