This means that a 60 watt led light is much much brighter than its metal halide counterpart.
Metal halide vs led power consumption.
Leds are designed for lower energy consumption and as such naturally have a lower wattage.
Therefore you cannot base your decision on watts.
A new 400 watt metal halide lamp is rated to last up to 20 000 hours.
There are few maintenance costs associated with led during the lifespan.
Starting accelerates the consumption of electronic emission substances on the filament.
Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient.
Existing lighting current wattage of bulbs.
The initial cost of leds is higher than metal halide and other traditional fixtures however the payback over time is very high.
Led high bay vs metal halide.

Only fixture cleaning if needed.
Led chips are mounted on a circuit board so depending on the configuration usually 180 degrees.
They lose roughly 15 of their heat emissions which adds to their inefficiency.

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 lights have a lower initial cost but are expensive to maintain.
Instead you need to focus on the number of lumens you need.
Leds last exponentially longer requiring little to no maintenance and have great energy efficiency.
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.
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.
However when it comes down to the numbers the energy efficiency of an led far exceeds that of a metal halide lamp.
Metal halide bulbs are valued for their high luminous efficacy 75 100 lumens watt and intense white light.
