What the AI looks for in Plant Growing Light Bulbs
- Base and form factor
- Match the socket (E26 in North America) and the shape (A19, BR30, PAR38) Larger high-output bulbs often do not fit lampshades or enclosed fixtures.
- Real output
- Prefer bulbs that publish PPF in micromoles per second over equivalent-watt claims Equivalent-watt figures on grow bulbs are marketing and do not measure plant light.
- Enclosed-fixture rating
- Only use in enclosed fixtures if the bulb is rated for it Heat buildup shortens LED life.
Brands that matter
- GE: Mainstream balanced-spectrum grow bulbs.
- SANSI: Higher-output grow bulbs with ceramic heat management.
What to avoid
- Purple or red-blue bulbs marketed with huge equivalent-watt numbers
- Incandescent bulbs, which give heat, not useful growing light
