SANSI 24W Full Spectrum Grow Light Bulb
A 24 W ceramic full-spectrum grow bulb that screws into any E27 lamp - the cheapest credible way to keep a plant or seed tray lit through winter.
4.0 / 5
★★★★★ ★★★★★ Highly recommended
Strengths
- No special hardware - screws into any E27 lamp you already own
- Natural-looking 4000 K white light with near-perfect colour rendering, not a purple blurple glow
- Ceramic chip-on-board construction runs fanless and silent with good heat conduction
Watch outs
- The ceramic body gets genuinely hot to the touch - needs clearance from foliage and shades
- One bulb only covers a 45-60 cm circle usefully - collections need multiple bulbs or a panel
- Output falls off quickly with distance, so hanging height discipline matters
- Base E27 (UK/EU version; US variant is E26)
- Power draw 24 W
- PPF About 40 umol/s (UK listing figure)
- PPFD 227.5 umol/s/m2 at 30 cm (official PAR25 figure)
