Target PPFD
Set a crop-stage target in µmol/m²/s and evaluate uniformity across the usable canopy.
Light planned around the crop
Gavita lighting for measurable growing conditions
Match spectrum, PPFD, mounting height and controls to the canopy instead of starting with wattage alone.

A practical selection path
Six checks before a fixture reaches the ceiling
Daily light integral
Pair fixture output with photoperiod so DLI reflects the full lighting schedule.
Mounting geometry
Check spacing, clearance and beam overlap before selecting fixture quantity.
Spectral fit
Review spectral power distribution against crop response and worker visibility.
Thermal conditions
Allow for ambient temperature, airflow and heat removal at the driver and diode board.
Control interface
Confirm dimming range, zoning and controller compatibility before commissioning.
Straight answers
Questions that sharpen a lighting brief
Is the highest efficacy always the right choice?
No. Higher lm/W may reduce electrical load, while crop lighting also depends on photon output, spectrum, distribution and thermal behavior. The better decision is the one tested against the application.
How should coverage be checked?
Use a grid-based PPFD plan at the intended mounting height, then confirm edge values and uniformity rather than relying on a single center reading.
Integrated or serviceable components?
Integration can reduce size and simplify thermal design. Replaceable drivers or light engines can lower lifecycle service burden. Access, downtime and spare-part policy should decide the trade-off.
What limits need early attention?
Ceiling height, ambient temperature, moisture exposure, available voltage and control wiring can all narrow the feasible fixture set.
