Grow Lights for Small Indoor Gardens: What to Compare
Choose a light for the crop and the area it must illuminate. A bright-looking lamp is not evidence that the edges of a shelf receive enough light.
Compare coverage, not marketing wattage
Look for a coverage map at a stated hanging height and distinguish actual power draw from equivalent-watt advertising. Compare fixtures at the height you can actually provide. A fixture intended for seedlings may not support a large fruiting crop in the same footprint.
Check mounting and everyday use
Measure the shelf, allow clearance above plants, and choose a stable mounting system. Adjustable suspension makes it easier to follow the manufacturer's distance guidance. Check whether a timer is included and whether the light returns to its previous setting after power is restored. Keep connections clear of water and follow electrical safety instructions.
Estimate ongoing cost before buying
Use actual watts divided by 1,000, multiplied by daily operating hours and your electricity rate to estimate daily energy cost. Compare warranty terms, replacement parts and dimming controls alongside purchase price. Begin with the crop and manufacturer guidance, then watch for stretching or bleaching instead of relying on a universal distance.
