LeDinPro natural spectrum is continuous spectrum and imitation of sunlight. It is based on McCree plant relative quantum efficiency of spectral line, then further optimization.

Different from red and blue spectrum, LeDinPro natural spectrum obtains more advantages:

1.Suitable for all stages of plant growth;

2.Higher cost performance;

3.Comfortable working environment for worker operation; 

4.Can be a unique light source of indoor culture.

SPECTRUM ANALYSIS

LeDinPro natural spectrum contains abundant red light and blue light, and also sufficient green light. The red light and blue light mainly absorbed by top level leaves; the green light affects all leaves photosynthesis, to promote middle and bottom level leaves growing more.

SPECTRUM COMFORT TO WORKER

 

The light of Red and blue spectrum is pink and purple light. Under this light environment, the worker is really not comfortable, and also inaccurate to evaluate the plant growing status. (Photo-5: White light VS pink and purple light in vertical farm)

The common pink and purple light as shown.

This light not only brings uncomfortable working environment but also affect worker’s healthy.

According to IEC/TR 62778 security standard, to test the above spectrum. The result shows at PPFD: 70umol/m2/s working surface, maximum working time is only 63 minutes.
