Savings â Super Grow LED vs 1000w HPS. Super Grow LED electricity costs are approximately 50% of an equivalent HPS and the LED offers more intense light across a full spectrum which gives bigger yields per Watt. Save on replacement bulbs. An HPS operates at full capacity for 2,000 to 3,000 hours versus the Super Grow LED at a massive 60,000 hours. Save on ventilation costs and space. Super Grow LEDs produces near zero heat which means no heat signatures, no need for fans, exhaust and ventilation systems or extra space.
