So i know LED's work, but im wondering how much better a HPS light would work. I know there suppose to be the standby but i also know they are incredibly wasteful in energy. I would like to try one though and see how it goes.
My question is this how do the watts of a LED compare to the watts used on a HPS? For example would a 90watt LED compare to a 150w hPS? or a 240w LED compared to a 250W HPS?
Also i was trying to figure out how much running a 400 watt HPS would cost (12hrs a day for 30 days) and i got about 14-15 dollars a month. Does that sound right to you?
How much light in your experience with LED or HPS is needed for a space 4ft x 8ft
I appreciate any advise you can offer!
