Light Output and PPFD

Total Luminous Flux

18W * 220 lm/W = 3960 lumen

PPF (Photosynthetic Photon Flux)

18W * 3,0 µmol/J = 54 µmol/s

Daily Light Integral (DLI)

DLI is calculated as

DLI = PPFD * 3600 sec/h * light hours / 1.000.000

Example

At PPFD = 250 µmol/m²/s and 16 hours of light:
DLI = 250 * 3600 * 16/1.000.000 = 14,4mol/m2/day 

Recommended Usage

Seedlings and Cuttings

100-200 µmol/m²/s

Vegetative Growth

200-400 µmol/m²/s

Flowering

400-600 µmol/m²/s

For optimal results, we recommend combining multiple panels to achieve even coverage over a larger area.
The panels are most effective at a distance of 5-20 cm from the plants.
We recommend a distance of 30-40 cm for seedlings/cuttings, 20-40 cm for vegetative growth, and 5-10 cm for flowering/fruiting.
