Is the Ultra800 energy-efficient?

Yes. With an efficacy of 2.6 µmol/J, the Ultra800 is far more efficient than HPS lights. For comparison, older HPS average 1.3 µmol/J, standard DE HPS reach 1.7 µmol/J, and premium units peak at 2.1 µmol/J. The Ultra800 produces more usable light per watt, saving up to 30% in electricity while delivering higher yields and healthier plants in demanding indoor environments.
