Buying Guide

Choose the right form factor

Select between PAR38-style bulbs for lamp or reflector fixtures and compact puck LEDs for shelves and compact grow boxes to match your fixture and canopy size

Check the light spectrum

Full-spectrum or broad-spectrum LEDs support both leaf growth and flowering in herbs better than narrow red-only or blue-only bulbs

Compare lumen and PAR output

Use lumen and PAR (photosynthetic active radiation) numbers when available to estimate usable light—higher PAR generally means better growth for densely planted herbs

Consider timers and controls

Built-in timers or external timers help maintain consistent photoperiods for herbs; some puck lights include simple timers for automated cycles

Weigh brand reputation and reviews

Look for consistent customer ratings and established lighting brands to reduce the risk of early failure or inferior light quality
