Most large fixtures use metal halide bulbs.
Convert 400 watt metal halide to led.
A metal halide light that produces 30 000 lumens discharges 75 lumens per watt.
The only viable solution currently is to have a module that is matched in size and weight as mentioned but then also has optimised light output to compare with the metal.
Commonly a 250watt 400 watt or 1000 watt.
Many of the concepts are the same but there are some differences between 400w and 1000w metal halide.
This blog post is our second to one of our most popular ones how many watts does it take to replace 1000w metal halide.
If the initial lumens produced by each 400w metal halide fixture were 30 000 you should get led fixtures that produce 30 000 lumens.
The reality is that they come in a large variety of options.
