Everything You Need To Know About Kessil LED Grow Lights

Kessil LED Grow & Aquarium Lights are cutting edge lighting fixtures combining efficiency and the newest lighting technology to deliver potent and effective solutions for gardens and aquariums. Traditional LED Chips vs. Kessil's Dense Matrix LEDs Although light output has increased significantly in recent years (especially with the introduction of 1W LEDs), basic packaging method remains largely unchanged. Industry standard still assembles one LED chip at a time: one LED die is placed in a reflective cavity, bonded to two electrical contacts, and then sealed by an epoxy or plastic lens. Instead of individually wrapped LED chips, Kessil applies a brand new platform that densely packs many of them together. For example, Kessil's H150 grow light uses a dense matrix platform that carries 21 LED chips in a circle smaller than a dime! This patented design is the result of over 30 million dollars in investments and five years of diligent research by DiCon. Its team of Ph.D's found a way to fundamentally resolve the thermal issue and invented a metal carrier that dissipates heat away from the core quickly. With this advanced innovation, Kessil is able to design a product that can operate at high currents and put out more light that can be effectively focused into intense beams, while still running at a device temperature much cooler than other grow lights. Through this patented platform, we have easily conquered the two biggest challenges in designing LED fixtures, beam control and heat management, to produce a grow light that not only penetrates plants deeply, but also runs cool at higher efficiency with a longer lifetime.

Detailed Overview: Kessil H150 & H150W (wide) Grow Lights
 
General Purpose, Special Penta-band Recipe 
The PURPLE model is a general purpose LED grow light that can carry many different kinds of plants through the whole growth cycle. This special penta-band recipe combines five different types of red and blue LED chips to create a spectrum that works for every stage of plant growth.
 
Flowering Emphasis, Unique Quad-band Formula
Similar to the PURPLE model but with a much higher ratio in the red spectrum, the MAGENTA model is a general purpose LED grow light that focuses on performance during the bloom phase. This unique quad-band spectrum blends four different types of LED chips together and is ideal for the flowering stages of growth.
 
Bloom Booster
This distinctive RED model is created to work alongside any grow light system. Taking advantage of H150's compact size, this booster light can be easily integrated into most indoor gardening environments. The all red emission will both increase photon intensity and balance the spectrum to the desired region during the blooming and fruiting phases.
 
Vegetation Enhancer
The BLUE model is aimed at enhancing vegetative growth without sacrificing yield. Working in conjunction with conventional or advanced LED lighting systems, this booster light will promote stem growth and reduce internodal length. Use this one-of-a-kind LED grow light to supplement the blue spectrum at any time to keep plants healthy and strong.
 
Bloom Booster
For gardeners who grow solely under fluorescent or HID sources, this RED spectrum is a perfect yield booster for the flowering and blooming phase. Mixing 30% 635 nm and 70% 660 nm LED, this well-balanced red spectrum provides improved results while consuming a minimal amount of energy.
 
Vegetation Enhancer
Illuminating alongside HPS or fluorescent lighting, the BLUE model is aimed at making stronger plants that will then produce more results. This spectrum is also ideal for cloning plants and is suitable for use with most cloning machines on the market.

A350 Features, Specifications, & Spectrum A350 Aquarium LED Light The Kessil A350 Dimmable Tuna Blue 90 Watt LED Aquarium Light is the next thing in LED aquarium lighting. As with other Kessil LED aquarium lights, this light has a densely packed LED array. However, with this "Tuna Blue" light you can manually adjust the mixture of blue and white LEDs (using the two knobs on top of the light) to find the optimum spectrum for your tank and corals (thus, Tuna Blue or tune the blue). The Kessil A350 Dimmable Tuna Blue 90 Watt LED Light brings out the vivid colors of corals with the specially created spectrums of the A350. While it is hard to compare the Kessil to 250 Watt metal halide lights, the 90 Watt Kessil has a greater effective light spectrum for corals than a 250 Watt metal halide. This is partly due to the efficient use of electricity with LEDs, partly a function of higher percentage of the light being directed downward and partly because a very high percentage of the light spectrum with the Kessil A350 Dimmable Tuna Blue 90 Watt LED Fixture is useful to corals. The Kessil A350 will result in thriving corals with lower electricity bills, less of a need for a chiller and no bulb replacement costs. The lightweight Kessil light, which weighs just over a pound, can be easily hung above the tank from with the two built in mounting tabs (that can be attached to a chain or other hanging mechanism), or can be clamped to the tank with the Kessil A350 & A350W LED Light Pendant Gooseneck Clamp/Mount. Features:
  • 90 Watts: Effective light greater than a 250 watt metal halide. Note: 90 watts is the maximum output. The output will be less if you turn down the blue or white LEDs

  • Video Transcript: "Hey everyone this is Nate with Growers House and today we're going to show off some of our favorite LEDs, the Kessil units. Kessil makes LED units for aquariums and for growing purposes of plants. Today we're going to show off specifically the ones they make for plant growth. The first one I'm going to show off here is Kessil's original unit, the H150. Now this unit [LED board] is made up of a dense matrix array that has multiple LEDs to make combined total of 36 actual watts of power consumption. This unit I'm showing you here is in the purple spectrum; and they make this unit in a blue, red, purple, and magenta. The blue spectrum is primarily made to be used as supplemental lighting in the vegetative phase to your main light, whether that be another LED or a Metal Halide (MH) light or a T5. The red spectrum is made for supplemental lighting for your flowering phase, whether you're using High Pressure Sodium (HPS) as your main light or any other form of red lighting. The purple spectrum unit is actually a mixture so that it's primarily for your vegetative phase, and the magenta spectrum is a mixture, but primarily for your flowering phase. Now moving over to the H350, this is Kessil's new unit. This is 2.5 times as intense as the H150 unit. The H350 consumes 90 watts of power. The H350 also has a dense matrix array, and also has the same beam angle of the H150, which is 60 degrees. [H350 only comes in two spectrums: H350 Purple & H350 Magenta] Both the H150 and H350--you can't see the array through the screen--but inside there are essentially a bunch of tiny LEDs on a very small panel that make up the lighting source for these units. Like I said earlier, they both have the same beam angle, so if you hold these lights at one foot above the ground they would have the same footprint, but the H350 would be 2.5X as intense as the H150. What I want to do now is plug these both in, and I want to show you what they look like when they turn on, what they sound like, and the different color spectrums. Here we go, we're going to start off with the H150. I'll put it down here so it doesn't blind anyone because these guys are bright. If I hold it up here and be quiet for a second you will barely hear the fan inside going, just cooling the light. Now if I hold it up here, you might be able to see the color that it's emitting a little bit better. They say the H150 at 12" to 18" above your grow space will have about a 2' diameter footprint. I'm now going to compare this light to the H350. Just so you know these units do come with a long cord so you can hang this from easily a 10' ceiling or higher. The H150 only weighs about 2.3 lbs and there's little to no heat coming off this light--it might warm up a little bit later, but it is a very cool operating unit. I know Kessil put a lot of technology into keeping the H150 and H350 cool, including fans, heat sinks, and some other interesting technology including thermal plates. Let's leave this H150 plugged in so we can readily compare these two units as far as their spectrum goes. Now I have the H350 plugged in and going, and the fans are a little bit stronger, so you might hear them a little more. This unit, if I hold it up, will give you a little bit of a more red spectrum than that one we just took a look at. Hanging the H350 12" to 24" above your plants you can expect to have a 3' diameter if you're closer to 24" above your plants. If I alternate between the two you can see the difference in the spectrum. Here's the magenta, and here's the purple. Magenta, purple. Lighting them up next to each other you can see that the magenta obviously dominates the spectrum, so you'll only see that pinkish spectrum. The H350 is also really light weighing only about 4.1 lbs. By the way the dimensions of this unit is 4" in diameter by 4" high. The H150 is about 4.5" high but only about 2.5" in diameter. I'll turn these guys off and that's about it. If you have any more questions about Kessil units, leave them in the comments below. Other than that, have a good one." Kessil LED Plant Grow Lights H150 & H350 Review
