490w LED COB Grow Light

Product information

This grow light is the perfect solution to replacing high energy, high heat HID lighting.

COB Chip Advantage

As the core part of COB LED grow light, the quality reliability of COB plays the most important role in the whole lifespan of grow lights, Nationwie made years efforts developing world-class COB light source with cutting-edge technologies --- thermal-electric separation technology and super heat-transmission material, it is totally a technical miracle, ensuring super strong quality assurance, we got two patents for our COB light sources, which are perfectly suitable for any grow purpose.

Multi-band COB supports different diodes of different colors mounted on the COB frame, it is suitable for those who request different spectrum or multi-channel control for different grow purposes, it provides good flexibility for growers to have different tailor-made spectrums for different grow stages or different plants.

Phosphor COB is designated based on full spectrum technology, it is suitable for the whole growth period of plant, it also can be tailor-made for specific growth stages, unlike multi-band COB, phosphor COB just uses one or two kinds of diodes in its making, its super heat-transmission rate make it enjoy the best quality assurance for very long lifetime use.

Spectrum

It is undoubtfully that spectrum is the first important factor for people to design or develop a grow light, because it is well recognized that all the plants in nature has their own spectrum in vegetative, blooming and fruiting stage, and people usually will have to take a long time to make many kinds of tests till the optimum spectrum comes out for mass production.

Light spectrum comes as the first importance, because different plants, in nature, has their own favored spectrum for the best growth, no matter in vegetative stage or blooming stage

Light Mixing

Quite few realize that light mixing can be the second important factor for grow light, but the test shows there is a difference result although spectrum, PPFD are same, better light mixing is surely able to give better result (speed & yield)

As is known to all that in the surface of leaves of plants, there are millions of plant cells (photosynthetic pigment) need to absorb photons for the photosynthesis in their different growth stages, the plant will grow perfectly only when the plant cells are able to maximally absorb light in same spectrum, otherwise, the growth of plant will be affected due to poor distribution of different colors of light. So far, the grow tests have improved well that the color mixing is very important to achieve good growth result; However, the importance of mixing of different colors of light is usually undervalued or neglected by many grow light designers, and people usually just choose diodes in different wavelengths according to the spectrum that they would like to have, but there always little attention paid to the mixing of different colors of light;

PPFD

If spectrum and color mixing are good, then the higher PPFD value the faster growth speed and more yield

PPFD (Photosynthetic Photon Flux Density) is mainly used as a measurement of light for plant, usually the higher PPFD, the better growth result, however, just pursuing high PPF may not workable and worthwhile to do, because different kinds of plants have their own light saturation point, only when spectrum and mixing of colors of light are perfectly ensured, then PPFD will work if the light saturation point is clear; in addition, spectrum and light-mixing should be placed as first priority before any other ways to increase PPF such as enhance electricity, etc.

HPS vs LED

In the markets of lighting fixture for cannabis, HPS still takes up big market share due to its cheaper cost and favorable yield, but its big power consumption and incredible heat emission are also big headache to cannabis growers, they have to pay much more on electricity and introduce expensive equipment for cooling, otherwise, it will affect the growth and yield, LED grow light is a perfect solution at all levels compared to HPS lamps, here we would like to share all details of comparison.

LED grow light is able to provide precise spectrum by specific bands(UV, blue, red and FR) which are perfectly for the growth of cannabis, and it is also able to make cannabis grow faster with more yield; From the below comparison, we can see that HPS is very short of blue and red color, it mainly relies on its high lumen output for the growth of plant, but it also produces too much heat and costs a lot on electricity
