5. Operating Instructions
5.1 Dimmable Full Spectrum Control
The BESTVA BP4000 features a dimming knob that allows you to adjust the light intensity from 25% to 100%. This precise control enables you to tailor the light output to the specific needs of your plants at various growth stages, optimizing energy consumption and plant development.
