Who This Is For
- You are upgrading to high-intensity LEDs because your current fixtures cannot hit the light levels needed for a 4x4.
- You are switching to automated dimming because manually adjusting light intensity twice a day is a waste of your time.
What We Found
- The 3.0 efficiency rating is real, as we noticed rooms stay significantly cooler during peak summer runs.
- We recommend the EL3 controller because it makes managing the 1900e far easier than using a basic mechanical timer.
What Users Say
- Users running this in tight 4x4 spaces report that the lower heat makes environment management much simpler.
- Facilities that integrated the EL3 controller found that automated dimming saved them hours of daily labour.
