i am building a workshop and searching for lighting. it's 60' by 80'. i prefer the high bay lights and have some 400w Metal hallide highbays in another shed and these are good but i believe they use lots of electricity. Are the LED lights anywhere near as bright as these. The lumens on LED high bays are about 10% of the equivilant metal hallides. Will 4 be enough for this area or will i want more.

Saw these LED bulbs in the Candle Power Forums. Not sure if they are anything you could use.

I see "high bay" lights at Home Depot. They claim somewhere around 30,000 lumens. How many lumens do you need?

I also see a couple from HD that are around 18,000 lumens. So...to respond to your original question...yes, it seems LED lights are clearly as bright as these. Whether, or not, you want to spend the money, I will leave to you to decide.

According to our friend Mr Google, a good starting point is 100 lumens per square foot. You have 4800 square feet, so you would need 480000 lumens total according to this formula. This probably assumes you want every square inch lit, which you may not. I am also sure it depends on what you intend to do in this space.

Four of these fixtures:

will get you about 120000 lumens. That is about 1/4 of the total required by the standards I found on a google search.
