Lighting Comparing hid lights to led lights

[Surfer Joe]

What would be the equivalent to a 400 w MH and a 600 w HPS light when using led light fixtures?

I like the idea that you can position the lights on top and also around the plants to get better lighting on the side branches, but I don't know how the light intensities compare and what types of led lights would give me the same sort of light amount when vegging at 400w MH and flowering at 600w HPS, and would I see a significant drop in electricity costs by switching?

Thanks for any advice.
