What makes these LEDs so much better than HPS for indoor growers?

1.) Efficacy Lighting uses Chips on Board (COB) LEDs by Cree. COBs are extremely efficient at converting electricity to light. Conventional HPS bulbs waste electricity by generating heat.

2.) HPS bulbs need to be replaced often. Most indoor growers purchase bulbs at least twice a year. LEDs have a rated lifespan of over ten years or more. 

3.) HPS bulbs emit light in a wasteful 360* pattern requiring the need for reflectors and air cooling. COBs emit light in a 115* angle spreading light efficiently throughout the canopy increasing photosynthesis. 

4.) COB LEDs increase the number of light sources over the garden eliminating dim spots and shaded areas.
