Indoor cannabis cultivation is a major energy consumer. The lights used to grow cannabis can account for up to 50% of the total energy usage of a grow operation. This can be a significant expense, especially for large-scale growers.


To stay competitive, indoor cannabis growers are always looking for ways to reduce operating costs and improve efficiency. Reinfa’s grow light lift, developed in close collaboration with cannabis industry customers, can help reduce power consumption by up to 20% and improve growth results owing to higher light efficiency. Safely and efficiently moving lights and flexibly meeting plants’ needs in different periods with optimal light intensity, growers can achieve a better light strategy and make their plants happier through the grow light lift.

Indoor cannabis growers typically adjust light power instead of height, as adjusting height is labor-intensive. According to the feedback from our customers, we learned mostly they use 60% of the light power during the vegetative stage and 100% during the flowering stage. In this case, we conduct a rough power consumption comparison to see how using a light lift would affect the results.

Assuming two 800-watt LED grow lights cover a 4-by-8-foot area, here is the calculation.

A rough estimate is that 300 kWh of electricity can be saved per 4-by-8-foot area per rotation! Once the light power is reduced, other power demands like HVAC can also be decreased in tandem.

Reinfa grow light lift is a motorized system that raises and lowers grow lights, so growers can safely adjust the height of the lights to ensure that they are always at the optimal distance from the plants. The closer the plants are to the lights, the higher the photosynthetic photon flux density (PPFD) they receive, which means that growers can use less wattage to achieve the same level of light intensity.

So, in addition to reducing power consumption, a grow light lift can also improve light efficiency. When the lights are closer to the plants, the light is less likely to be wasted. This is because the light is more likely to be absorbed by the plants instead of being wasted in the air.

In conclusion, the benefits of using a grow light lift for indoor cannabis cultivation you can expect: 


  • Reduces power consumption by up to 20%
  • Improves light efficiency
  • Maximizes light penetration
  • Extends the lifespan of grow lights
  • Makes it easier to adjust the height of the lights
  • Can be automated to save time and effort
