Large grow facilities often use 208V, 240V, 277V or higher-voltage distribution to reduce current, while many commercial fixtures support a broad input-voltage range. The correct voltage is whichever the exact fixture and facility electrical design support.
Lower current can reduce conductor size and voltage drop across a large room, which is why commercial horticulture commonly uses higher-voltage circuits. It does not make the LEDs themselves produce more photons.
Confirm fixture input range, plugs/whips, branch-circuit loading, dimming network and local electrical code. A small mismatch multiplied by 100 fixtures becomes an expensive problem.
For “What Voltage Is Best for Commercial Horticultural LED Lighting?,” these three models give you concrete products to compare against the requirements above, instead of leaving the answer at theory.
Our strongest starting point because its high-output full-spectrum led and dimmable make it a concrete model to use when checking the seller’s electrical listing before purchase.
A useful second comparison because its bar-style led and dimmable high-output fixture make it a concrete model to use when checking the seller’s electrical listing before purchase.
A contrasting third option because its multi-bar led and dimmable make it a concrete model to use when checking the seller’s electrical listing before purchase.
