Technical Specifications
Model | CultiKit LED36 (MK_230808LED V1.0) |
Dimensions | 140x120x10 mm (WxDxH) |
Weight | 116 g |
LEDs | 36 pcs Samsung LM301B (12x5000K + 24x3000K) |
Power Consumption | 5-18W |
Luminous Efficacy: | 220 lm/W |
Spectrum Range: | 400-700 nm (PAR range) |
Supply Source | 24V DC PSU |
Input Voltage | 24V DC |
Output Voltage | 3.3V DC ± 5% |

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 |
Photosynthetic Photon Flux Density at Different Distances
Distance (cm) | PPFD (µmol/m²/s) |
5 cm | 1755 |
10 cm | 560 |
20 cm | 192 |
30 cm | 108 |
40 cm | 73 |
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: |
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.
