If the initial lumens produced by each 400w metal halide fixture were 30 000 you should get led fixtures that produce 30 000 lumens.
Convert 400 watt metal halide to led.
The reality is that they come in a large variety of options.
Many of the concepts are the same but there are some differences between 400w and 1000w metal halide.
A new metal halide bulb can get almost 100 lumens to watt.
This blog post is our second to one of our most popular ones how many watts does it take to replace 1000w metal halide.
Most large fixtures use metal halide bulbs.
Commonly a 250watt 400 watt or 1000 watt.
Additionally if clubs are wanting to replace metal halide fittings with led the modules have to be similar to the metal halides in dimensions and weight for the same reason.
