New lens give more PAR value and deeper penetration. 

Coverage and PPFD

Some LED manufacturers tout their high photosynthetically active radiation (PAR) values. Their
fixtures produce more PAR, they say, and therefore are superior.
Not so. A lighting manufacturer should tell you that you need to ask about the photosynthetic photon flux density (PPFD).
PAR is defined by the International Commission on Illumination as the total photon exposure in the 400nm to 700nm waveband range of radiation that is absorbed by photosynthetic pigments.
PAR is not a quantitative measure; it’s merely a description of the light that plants need for photosynthesis. PPFD, on the other hand, is a quantifiable measure of the total number of photons in the photosynthetically active range of wavelengths that fall on a square meter of a given surface (say, a plant canopy) every second. In other words, PPFD is a measured metric whereas PAR is merely a descriptive term for a range of wavelengths.

Spectra Sheet

Pink Full spectrum, 

Raito: 380nm ~850nm 

Why MCOB?

1st . Combine the different LED into a base board, then the different color will be mixture better.

2nd . Lighting from chip will have a little loss when pass through the lens, MCOB put LED together, then the loss will be smaller than the Each LED diode have each lens.  

1.Why is red light and blue light important for plants?

Red light is very important to plant reproduction. Phytochrome pigments absorb the red and far red portions of the light spectrum and regulate seed germination, root development, tuber and bulb formation, dormancy, flowering and fruit production.
Blue light stimulates Chlorophyll production more than any other color, encouraging thick leaves, strong stems and compact vegetative growth.
Red 630 ~660nm: Best for photosynthesis and photoperiodism. Blue 460nm: The Chlorophyll and Carotenoid need it much, good for the photosynthesis.

2.Who would use an LED Grow Light?

LED Panel growing systems are used by home gardening enthusiasts, top florists,large nurseries, scientific researchers, universities. Even NASA uses LED grow light technology to grow plants in space!
