Today we ’re profiling a new character of LED light to hail on the marketplace fromThe Green Sunshine Company . The proprietor , Dan , reached out to me and we get on the phone to talk about the tech . He actually helped me sympathize plant biology and perch at a deep grade , which prompt me to write this piece today . He even show me some interesting results in hisHPS vs. LED rise timelapse , which was yet another ground for me to take a mystifying look at his light .
Plus … Ilovelighting technology . I ’m a total nerd about it . So I could n’t resist diving in !
I ’ll be wait at the Electric Sky lights , but before I do that I have to get into some mythology that is often spread out by LED lighting fellowship .
Here we go !
Myth: Plants Only Need Red and Blue Light
This is one of the reason you see imperial light-emitting diode everywhere . You ’ll often see lead companies that manufacture older narrowband unit display a chlorophyl A / B absorption graphical record when touting their purple LEDs , showing that they are yield plants the exact spectrum that they can ingest .
While this soundsgreaton the surface , in reality it ’s a bit of a merchandising trick . light-emitting diode company are most efficient at creating red ( ~650 nm ) and gloomy ( ~450 nm ) diodes , so it ’s no surprisal they expend the chlorophyl A / B chart .
In reality , a folio is absorbing much more than just red and blue light . immature and yellowed light in the 500 - 600 nm range is being absorbed by leaf tissue as well . dissimilar parts of a plant ’s folio immerse unlike portions of the spectrum . chloroplast , which are the centers of photosynthesis , are taking in quite a chip of fleeceable , jaundiced , and orangish light .
So much for green light “ bound ” in good order off of plant leaves , huh ?
Myth: Use Blue Light for Veg, Red Light for Flower
This is an outdated firing “ fact ” that come from the time when grower would use Metal Halide grow ignitor for vegetal leg and High - Pressure Sodium lights for the florescence phase . Technically talk , neither MH or HPS light aredesigned for plant life growth , but theyaremore suited towards their respective phases .
LED companies have mimic this by offer different modes , often go as far as to create toggles on their lights in rules of order to tack between aristocratical and red diodes . This is often a mistake as we ’ve already discussed how plant life apply much more than a single band of the light source spectrum throughout all phases of growth . After all , they usually grow under the sun !
There are many more myths about light-emitting diode kindling and perhaps I ’ll do a full breakdown of those in a future article , but for now get ’s get on to the Electric Sky lights .
The Green Sunshine Company’s “Electric Sky” Light
There ’s a lot that make these lights unequalled in the conduct space , so let ’s take the features one by one :
Dual-Way Linear Lenses
The first and most interesting affair about the ES lights are the linear lens . They ’re call “ Electric Sky ” lights because they ’re design to mimic a miniature variant of the sun ’s output versus being a point - source of luminance like many LED pattern .
They put out a precise rectangle of light due to these linear lenses , which to my knowledge have yet to be used in grow firing .
The finish is to project the visible radiation out and down , rather than all - down ( as you ’d see in a limelight ) or all - out ( as you ’d see with no lens system ) .
Here ’s a charge comparing the chroma and height location as compared to normal LEDs . As you’re able to see , you get a magnanimous sweet position of light volume and you ’re able to localise the luminousness nearer to the plant life canopy . base on theinverse square law of spark and aquiculture , we know this means better plant ontogeny due to increased intensity !
Spectrum
While the accurate point of the GS1 spectrum are proprietary , it ’s plan using broadband LEDs and call to improve on both purple light-emitting diode and white LEDs . It sum a important amount of red and infrared . When I asked Dan , he mentioned that hoi polloi tend to analyse plant concentration of light based on individual spectrum ranges , when in realism there is a combinatoric core at gaming . That is to say , when given certain spectra , a plant may habituate more or less of another spectral range in response . It ’s a complex topic that scientists are still learning a lot about !
The way out with imperial LEDsis that they have a hard time penetrating into the canopy , because what they do is give plants exactly what they absorb . This means the upper parts of the plant will block light from permeate the canopy .
The takings with whitened LEDsis that , while they infiltrate the canopy more , they but they are lacking in red and infrared light , which are vital for vegetational ontogenesis ( despite what some conceive ) and also good anthesis results .
Electric Sky Models Offered
The Green Sunshine Company offers two magnetic declination of lights :
They ’re effectively the same light , just with different wattages and proportion . Here are the detailed specs for each :
Electric Sky ES180
This is the smaller model , at 180 “ on-key ” watts , NOT an HID equivalent wattage . That means you get what you see on the specification sheet , which is a nice alteration for an light-emitting diode company .
truthful Wattage : 180 Watts
light-emitting diode : Top - Bin Mid Power Wideband rectifying tube
Beam Angle : duple - fashion Linear Lens 60 ° x 120 °
Spectrum : GS1 “ Wideband ” Spectrum for Flowering plant ; create larger leaves and staunch for exponentially immobile ontogeny in veg & massive yields in bloom
life : Estimated 90 % brightness level at 60,000 hrs
Coverage Area :
Hang Height :
Dimensions : 24.5L x 12W x 2.5H inch
weight unit : 14.5 lbs
Voltage / Amperage : AC100~270V ; 1.5A @ 120V / 0.75A @ 240V ; 50Hz – 60Hz
Electric Sky ES300
This is the cream of the crop model at 300w . It ’s capable to grow just about anything you’re able to get indoors , from vegetative plants like St. Basil and lettuce all the manner through peppers , tomatoes , and other works that are dense fruiters .
honest Wattage:300 Watts
LEDs : Top - Bin Mid Power Wideband Diodes
Beam Angle : Dual - mode Linear Lens 60 ° x 120 °
Spectrum : GS1 “ Wideband ” Spectrum for Flowering Plants ; create larger leaves and staunch for exponentially faster growth in veg & massive return in efflorescence
Lifetime : gauge 90 % brightness at 60,000 hrs
Dimensions : 36L x 12W x 2.5H in
weight unit : 22 lbs
Voltage / Amperage : AC100~270V ; 2.5A @ 120V / 1.25A @ 240V ; 50Hz – 60Hz
All in all , I ’m super aroused about this case of evolution in the LED light securities industry and I ca n’t hold back to get my hands on one of these models myself before long . When I do , I ’ll be conducting a full pepper grow with it and giving away some of my old lights ( a humankind can only have so many ! ) .
