ViperSpectra is a renowned brand of LED lights, the quality of this LED light is very high. The 450 W reflector provides a full light spectrum. The 12 band light spectrum is an excellent source of light for both stages, vegetative and flowering. It is important to highlight that it produces more red light, making it slightly more beneficial for the flowering stage but still adaptable to any part of the plant’s life. It has upgraded fans that help heat dissipation as well as big sinks so it will not overheat.

The Good

  • A surprising lifespan of 100,000 hours.
  • The package brings an excellent hanging kit.
  • 6ft long power cord.
  • High-speed fans that help during the cooling process. It is probably the best cooling system in LED grow lights of this size.
  • Excellent and professional design.
  • Compact and maneuverable.
  • Can be controlled by a timer.

The Bad

  • Extremely bright. Requires protective glasses when using it.

Reviewing the Viparspectra Reflector series 450 Watts LED Grow Light. Well, the first thing we noticed that the light is well boxed, well packaged. We have a 3 prong power cord here that’s going to fit right into the light and some light hangers. So these are just the hangers. You’re going to need additionally adjustable hangers if you want to adjust this light up and down in your grow space. Let’s take the top off and look what’s under here. All right. Looks like we have an instruction booklet. Always helpful. It’s got some safety information. Some specs on the light. Some basic info about photosynthesis it looks like. Some par data and of course the warranty terms. And the warranty card just in case you have any problems with the light. Okay. This unit feels pretty sturdy. It’s heavy. You can see the LED diodes are surrounded by reflectors which helps focus and reflect the light. On the side here we have a Veg and a Bloom switch. So the Veg is going to be used obviously for Veg. And while you’re blooming, you’re going to want to use both switches. And good ventilation. You have ventilation on all sides. Here’s where the power cord goes. And it looks like it’s also daisy-chainable. Info on the power. Input voltage frequency. Got two cooling fans on the back. Looks like a great light. All right. Well. Let’s turn this on and see what this looks like. This light’s designed to replace a 400 Watts HID Grow light. It only consumes about 200 Watts at full power and it’s perfect for a 2.5 x 2.5 space for flower and a 3.5 x 3.5 foot space for Veg.

ViparSpectra 450w features

So turning on the Veg switch. You can see there’s two different types of white LEDs.  And probably a couple different types of blue LEDs as well. I’m going to turn that off and just turn on the flower. So there’s several different diodes on here with flower. Looks like the white, two different types of red and some dim LEDs. These are the IR LEDs. So they’re at full power even though our eyes can’t really see them. They’re providing additional benefits to your plants. So this is a full power, drawing about 200 Watts. This is the full spectrum here. This spectrum’s really heavy and blue which some people may not like. However, if you look at reviews on Amazon or talk to other growers that have grown with this, they’ve gotten great results with this spectrum. So you shouldn’t necessarily let the high blue scare you away. It just comes down to preference and possibly some testing in your own grow room to see if this light would work for you. Again, most people love it. I don’t think anyone has had a problem with the additional blue. But I just wanted to point that out. Sweet. Let’s check out this light. Got the Veg switch on. Nice blue. Really lighting up the tent. This has taken about 4 feet above the bottom of the grow tent, which I don’t recommend using this fixture at unless you’re using it for seedlings. But I just want to show you what the light looks like. And now here’s the red spectrum. Really nice deep reds. Look at that. Beautiful. And both switches. Really lighting it up now.  Loving it. Loving it.

How does the ViparSpectra 450 light spectrum affect your plants?

I can see that’s full spectrum right there. Blues, your reds, your whites. Now that we’ve got the light in the tent, let’s measure the par at 36 inches. So 36 inches is going to be about what you want for the seedlings. We’re at about 118 micromoles. You’re going to want the light about a foot closer during Veg. However, I just took the reading here so you can see what it’s like for seedlings and just know that you’re going to get higher intensity during Veg as you move the light closer. Now I have both the Veg and the Bloom switch on, measuring the light at 18 inches above the bottom of the grow tent. And off to the side, there is low par. But as you move it under the light, it looks like it’s right around 370. And then as you bring the meter closer to me, it drops off. So 18 inches is the perfect height for a flower. You can have it as close as 15 inches. You can back it up a little bit to get a larger footprint. But your par is going to drop down. This is a sweet spot for a flower. Here are all the wavelengths included in the Viparspectra 450. So this really helps to round out the spectrum. And of course, the par data that Viparspectra attained, which is a little bit higher than my par data, but it’s pretty close. So I’m going to go with these numbers.
