In terms of running and maintenance costs, the LEDs outperform the HPS. These light-emitting diodes work with less energy to produce the same light level. With LEDs, you can save on ventilation and maintenance costs, as this equipment is much cooler and has longer lifespans. The main issue is that the upfront cost of LED equipment is higher than its HPS counterpart. But, you must consider the energy costs that would be saved over time.
