As far as I can see, at the same level power, LED's luminous efficiency is 90Lm/W, while HPS is 32.27Lm/W, So LED's LE is about 2.8 times of HPS. So a 600-watt HPS lamp is just getting the same luminous as a 215-watt LED, so you will save more money on the lamp and power consumption.
In the other way, a LED light can release the same full spectrum as the sunshine, it's warmer and lighter than an HPS lamp.
Besides, HPS lamps will release more heat than LEDs, so at the same distance HPS lamps will burn up leaves, and because an HPS lamp will release 360 degrees light, so it will hurt your eyes when you turn it on.
