Only fixture cleaning if needed.
Metal halide vs led power consumption.
The upfront costs may be low but once you factor in maintenance and the cost of electricity the metal halide fixture is one of the worst possible options you could use to light up your facility or grounds around your building.
A new 400 watt metal halide lamp is rated to last up to 20 000 hours.
Metal halide bulbs are valued for their high luminous efficacy 75 100 lumens watt and intense white light.
Metal halide lights have a lower initial cost but are expensive to maintain.
Starting accelerates the consumption of electronic emission substances on the filament.
Led chips are mounted on a circuit board so depending on the configuration usually 180 degrees.
The initial cost of leds is higher than metal halide and other traditional fixtures however the payback over time is very high.
Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient.
2 1 traditional hid metal halide lamps are not allowed to start frequently.
They lose roughly 15 of their heat emissions which adds to their inefficiency.

Both metal halides and leds are considered to be more energy efficient than incandescent lamps.
There are few maintenance costs associated with led during the lifespan.
This means that a 60 watt led light is much much brighter than its metal halide counterpart.
Because the filament of the lamp is impacted by high voltage every time the lamp is started the starting current is 2 3 times that of the normal ignition.
Leds last exponentially longer requiring little to no maintenance and have great energy efficiency.
Existing lighting current wattage of bulbs.
It is ridiculous because i have done the calculations on how much it costs to operate these metal halide fixtures.
Instead you need to focus on the number of lumens you need.
Therefore you cannot base your decision on watts.
Led high bay vs metal halide.
Metal halide fixtures provide indoor and outdoor illumination in many places that require wide overhead lighting such as athletic facilities parking lots warehouses and factories.
However when it comes down to the numbers the energy efficiency of an led far exceeds that of a metal halide lamp.
