CMH are more PAR efficient than either HPS or MH, making them a better single light solution.
CMH grow lights will let you see the true color of your plants without making your grow room look yellow, blue or purple.

CMH grow lights provide UV (ultra violet) radiation, which although being outside of our range of vision is beneficial (at certain ranges and intensities) to plant growth and development.

CMH grow lights tend to last over 24,000 hours while keeping at least 80% of their original intensity at the 20,000-hour mark.
This overshadows the common 10,000-hour replacement rule for HPS & MH bulbs.
