Hello everyone, Nate from GrowersHouse (growershouse.com) here and today we want to show off our newest test that we've just completed.
Apache Tech AT600 LED Review. We are showing off a new light that's introduced to the indoor growing scene from Apache Tech LED Grow Light Company. Now this is the AT 600 unit which is much larger than the other units you've seen the AT120's available before and those were the one that were developed in conjunction with NASA about 3 years ago. This unit is now coming in called the AT600 LED Grow Light and we measured at the wall (with a Kill-A-Watt Meter) this guy is hovering close to around 700 watts of actual power.
We are going to do a spectral analysis of this light with our spectralradiometer and do a footprint analysis with our PAR meter over a 4x4 footprint. Because that is what this light is actually rated for a true 4 by 4 footprint to replace a 1000 watt light. The spectrum put in this light that was sent to us, is one that is optimized for the flowering phase although can also be used during the vegetative growth phase.
We're going to turn it on and were hoping the camera can resolve the colors in this light because it is extremely bright. As you can see here to the eye there are bands of white and red and that's how the light appears to us. You'll see in the spectral analysis is that there are actually more colors in the blues that are coming off that we can't see.
You can see that this is a pretty big light; we are thinking that is weighs at least 60 pounds and has built in fans on each side for eight fans total to make sure they cool the leds. it says it will heat the led to about 90 degrees Farenheight which is a very cool temperature for this light. This light is completely made in the USA, assembled in Apache Techs warehouse in California. The spectrum of this led is optimized to increase yields and the specific compounds by the plants its set up for, over that 4 by 4 footprint. This light is also UL approved which, by our knowledge, is the first LED grow light with a UL approval which is big step for essentially becoming a more legitimate light in the industry. Apache Tech LED AT600 also carries a limited lifetime warranty and operates from 100 all the way up to 277 volts. It comes with a 120/240v plug so out of the box you can just plug it in and it will auto recognize 120 or 240 and you can start growing.
Let's put this under our meters and show you some data.
Here is some of our test data. As you can see we measured the Apache Tech LED AT600 at a standard wall outlet at 120v. We measured the amperage coming out at about 6.4 Amps. And we also measured the wattage at 742 Watts at the wall. We have also included a ratio of the average amount of PAR over the 4x4 footprint read at the 33 points of measurement over the total amount of watt draw at the wall. To come to the calculation we added up the numbers for the 24" height and total amount of watt draw at the wall for a ratio of PAR/Watts of 31.27.
If we scroll down the infographic we can see the analysis of the spectralradiometer. Telling us what the spectrum of light is coming from this light source. You can see the relative intensity is much higher around the 660 nanometer range in the red spectrum you can also see on the left a smaller bump around the 440 nm range in the blue spectrum and you can see everything in between. This light really is a flowering dominant light although it does have those other spectra so that you can use this light from seed to harvest.
Moving down to the 4 X 4 footprint analysis we measured this light with our PAR meter at 3 different heights, at 18" above the footprint, 24" and 30". You can see for each height we measured the 33 different points of intensity and this should hopefully help you gauge how high you want this light above the canopy for a good distribution versus intensity.
Keep tuned for more of the latest growing technology!
This is Nate from Growers House. Have a good one.
