How many watts per square meter: sizing LED grow lights for leafy greens and vertical farms

5W Trimless LED Downlight

Why this matters when you buy

LED grow lights for leafy greens require 30-100 watts per square meter. Size by crop type and growth stage. LOWCLED offers 60W-300W options, including COB and horticultural modules. Greenhouses, hydroponics, and vertical farms benefit from our spectrum-tuned solutions.

Specs and numbers to check

Check before ordering: the actual spectrum test report (not marketing numbers), coverage per unit, the thermal design of the COB, and whether the model dims for multi-tier racks. In humid greenhouses, confirm the IP rating and how the driver is sealed.

Applications and sizing advice

Seed starting, leafy greens, vertical farms, greenhouse supplement lighting and hobby tents are the typical jobs. Rough sizing: about 60W for one square meter of seedlings or herbs, 120-180W for leafy greens over one to two square meters, and 300W for flowering plants or a two to three square meter rack. Write to sales with your crop and area for a layout.
