"Hey everyone, this is Nate with Growers House and today I have two very special LEDs that were just released into the market for hydroponic and indoor growing. These LEDs are the new Pro Series LED lights from LumiGrow. The two lights LumiGrow came out with are the Lumigrow Pro 650 and the Lumigrow Pro 325. These units are replacing the old model lineup, which was the ES 330 and ES 165.

LumiGrow Pro Series 325 & 650 LED Grow Lights

The Lumigrow 325 and 650 model numbers represent the wattage that each of these lights are consuming. A lot of people may not that the last model was the 330 and LumiGrow has a 325 to replace that, and it's the same price, so how can it be better? The way the driver is designed in the LumiGrow Pro Series 325 is more efficient, and so are the LEDs. The old LEDs used by the LumiGrow ES 330 had a 22% efficiency rating, which meant that for every watt of energy input, there was 22% of that watt made into light output.

The new LumiGrow Pro Series LEDs now have a 47% efficiency rating. So with this new 325, even though it's 5 watts less, is putting out twice the light output of the old ES 330 model for the same price.

When you purchase these units they come with just a few simple components and then they're ready to go out of the box. What you'll get are two A hanging hooks, and your standard 120v cord, although both of these units are able to operate between 100 and 260 volts. These units will automatically know what voltage they're running on, so all you have to do is plug in the cord with the correct adapter, which looks like a new-age computer cord--the cords you also use commonly with digital ballasts--and this unit will be ready to go. That's important because a lot of research institutions and commercial growers are using these units, which lends to really how effective they are at growing plants.

What I really want to do is turn one of these LumiGrow units on and we can take a look at some of the features it has. Before I turn it on I want to give you a quick overview of the panel here. There are three dials that help you control the red spectrum, the white spectrum, and the blue spectrum of the LED diodes. What this knob does is goes from 0 to 10, 10 being the max intensity of that spectrum and accordingly as you go down through the numbers to 0, which is no intensity of that spectrum.

This is a cool feature that wasn't on the last unit. Essentially there's an eyeball and a leaf down here. The eyeball turns off the red and blue LEDs, so only the white is shining, which allows you to see your plants. I know with LEDs when you turn it on it's really hard to see what's going on with your plants because there's almost a purplish spectrum mix from the red and blue, but turning this up allows just the white to be shown so you can see if there are any difficiencies, the coloration of your plant, and it's a pretty cool feature.

Let's turn this guy on and see what it looks like. Really quickly before I turn the LumiGrow on I should show you--before it starts blinding everyone--that there are some built-in axial fans right here and here, and internally. This is the panel of the diodes, which are a combination of three and five watt diodes. Let's go ahead and turn this guy on.

You'll notice as I turn this on (oops, let's turn that down), I have it on the setting just for your eyes to be able to look down at your plants below. If I turn it to the flower setting with all of these knobs turned to 0, just the fans will be on, and then I'll slowly start turning up the red spectrum. And then I'll move onto the white. And now I'll turn on the blue. There you can see all three spectrums at full intensity with this unit on.

With that full intensity all the lights are on max output, and the reason why LumiGrow has these different intensity knobs is that some of the more expert growers may want to tinker with how intense their spectrum is during the vegetative or blooming phase, which primarily will affect internodal growth. So let's say during vegetative growth you might want to turn these reds down about half way so that you will be white and blue dominant, yet still having a red spectrum to make it full. Vice versa in flowering. So that is a very cool feature. Again, you're plants look funny under the red and blue light, click that and were back to white light as if it was the ambient light in your living room.

What we're going to do now is take both the LumiGrow Pro Series 325 and 650 units and put them under a PAR meter on our footprint and see what kind of intensity these guys are putting out. Let's jump into that!

Here we have our PAR readings over our 4' x 4' grow footprint at 12", 18", and 24" above that 4' x 4' for the LumiGrow 325 and the 650. We have these readings and readings on more units on our website, so be sure to click on the link below to go to our blog and see those readings. Here are some specs on the units."
