Buying Guide

Match light spectrum to plant stage

Full-spectrum bulbs mimic natural daylight and work for most growth stages, while some bulbs emphasize red or blue wavelengths for flowering or vegetative growth

Check actual watt and lumen output

Compare LED wattage and lumen output or 'watt-equivalent' claims to estimate brightness and energy use for your space

Consider bulb form factor and fit

Choose A19, PAR, or puck-style bulbs based on fixture compatibility and whether you need focused or wide-area coverage

Look for timers and control features

Built-in timers or compatibility with external timers simplifies light schedules, helping maintain consistent photoperiods for plants

Factor in price vs. pack size

Multi-packs can lower per-bulb cost for larger setups, while single PAR or higher-watt bulbs may better suit isolated specimens
