Only fixture cleaning if needed.
Metal halide vs led power consumption.
There are few maintenance costs associated with led during the lifespan.
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.
Therefore you cannot base your decision on watts.
Existing lighting current wattage of bulbs.
Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient.
Led chips are mounted on a circuit board so depending on the configuration usually 180 degrees.
Leds are designed for lower energy consumption and as such naturally have a lower wattage.
This means that a 60 watt led light is much much brighter than its metal halide counterpart.
The initial cost of leds is higher than metal halide and other traditional fixtures however the payback over time is very high.
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.
Both metal halides and leds are considered to be more energy efficient than incandescent lamps.
Led high bay vs metal halide.
Instead you need to focus on the number of lumens you need.
They lose roughly 15 of their heat emissions which adds to their inefficiency.
Starting accelerates the consumption of electronic emission substances on the filament.
Metal halide bulbs consume more energy than a led fixture and have a higher maintenance cost.
It is ridiculous because i have done the calculations on how much it costs to operate these metal halide fixtures.
2 1 traditional hid metal halide lamps are not allowed to start frequently.
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.
However when it comes down to the numbers the energy efficiency of an led far exceeds that of a metal halide lamp.
A new 400 watt metal halide lamp is rated to last up to 20 000 hours.
