Seriously consider your lighting options before committing
Your planning your brand new building and the year is 2020. LED lighting is the norm, but so is traditional 120V power to those lights. It doesn't have to be that way.
LEDs can be powered directly with low-voltage DC power, which is more efficient, more cost effective and offers a lot more flexibility. It can also position your building for the future. Building intelligence will be part of the data network. Your LED lighting should be designed to be part of that network. It will future-proof your building today.
