DormGrow G8LED 450 Watt Product Review

When it comes to the LED market, there are thousands of options that can leave you utterly confused as to which is the best for your needs.

Read along to understand why the DormGrow G8LED 450 Watt has garnered so many coveted awards and why this model seems to fly off the shelves.

A Brief Introduction to DormGrow

DormGrow is an American LED light manufacturer that’s excelled in the lighting industry by producing a vast spectrum of top-of-the-line LED lighting products for the horticulture industry.

In our eyes, it’s always important to look at the company before diving into the product, and from here, DormGrow is fully committed to customer support, best price guarantees, discreet shipping methods, and even a 90-day money-back guarantee.

All of these factors bode well for any company because it shows that they stand behind their product.

Now, let’s take a look at what exactly they’re so staunchly standing behind to offer so many perks for current and would-be customers.

Build Quality of the DormGrow G8LED 450 Watt

First and foremost, the build quality is what we look at to determine a products’ value. The DormGrow G8LED 450 Watt system is a single-piece system that doesn’t require assembly.

The body is constructed out of durable and scratch-resistant aluminum, which also keeps its weight to a minimum. Coming in at 22-pounds (10.4-kg), this is one of the lighter systems around that can be easily hung from a wide variety of locations.

All the required certifications are there, which include ETL, UL, CSA, CE, and Rohs. This is a critical point that we always stress because these certifications represent the safety that should back your new LED from potentially hazardous issues.

The glass panel in front of the diodes does not feel cheap, and instead, feels very robust. All in all, when moving the G8LED 450-watt around, all the internal pieces don’t shift around.

Now, let’s move onto the 90-watt Flower Booster. It weighs a featherlight 5-pounds (2.2- kilograms) and is professionally constructed out of durable aluminum.

There’s nothing about this item that feels cheap, but instead, it feels as though it should cost more. The 90-watt Flower Booster is also fully certified with ETL, UL, CSA, CE, and Rohs.

For us, we’ll never review products that do not conform to these international standards as they prevent the risk of fire or electrical damage.

G8LED 450 Watt System Light Spectrum

Let’s move onto another crucial part of the review – the G8’s light spectrum. First, the G8LED 450W is a full spectrum beast that contains a mix of 90° and 120° 3W diodes.

The mixture of the color spectrum includes everything from 380-740 nanometers. This means that your crucial blues, reds, oranges, and even white will be present in this fixture.

Additionally, the diodes push out UVA and UV, which plays a crucial role in plant growth.

If you didn’t know, then it’s exactly this range of colors that plants most effectively absorb – 380-740nm. In terms of colors that we can understand, these nanometers translate into red, blue, white, and orange.

Add all of these essential components together, and we’re looking at a full-spectrum LED that gives your plants everything they need.

According to our tests, the G8LED 900-watt LED system is right on the money regarding its claims of a maximum PAR rating of 1,580µmole/㎡/s. The PAR rating is measured in micromoles per square meter per second.

This rating shows how many photons hit the leaves per second, and the greater the number, the more efficient the light. This number was found by placing a sensor roughly 18” below the G8LED 900-watt LED system.

DormGrow 90 Watt Flower Booster Light Spectrum

Now it’s time to look into the 90W Flower Booster LED. This small – yet powerful – LED acts as supplemental lighting for its big brother – the 450W Veg/Flower LED system.

According to our measurements, the 90W Flower Booster LED pushes out 770µmole/㎡/s. The color wavelength is orange/red, which lands in the 600-650nm range.

It’s incredibly encouraging to see that this light emits the claimed amount of PAR, which adds to the companies claims and their trustworthiness.

DormGrow G8LED 450 Watt LED System Efficiency and Heat Production

The primary reason why most cannabis growers are transitioning to LEDs is primarily for a reduction in electricity consumption. The more energy you consume, the larger your electricity bill.

The G8LED 450-watt LED system pulls approximately 540W from the wall. This system is meant to replace a 1,000-watt HID, and at 540W, this LED will automatically cut your electricity bill in half.

Furthermore, at 540W, you won’t need to rely on a power-hungry AC-unit to continuously cool your grow room.

We ran the G8LED 900-watt LED system for hours in an enclosed room and barely noticed a significant change in room temperature. Its low wattage consumption and efficient fan design make for a quiet-running LED system that won’t turn your grow room into a furnace.

An additional benefit is that you can run the G8LED 450-watt LED system on a 110-240V outlet – as long as you have the proper connection.

We couldn’t be happier with the fact that this light can compete with 600-1,000W HID systems with a fraction of the demand in electricity.

The 90-watt Flower Booster LED performed just as well as it’s Veg/Flower counterpart. This supplemental LED consumes 80W from the wall (either 110-240V).

The heat produced from this workhorse doesn’t make a blip on the radar, and you can string an additional 90W Flower Booster LED at no penalty of heat production or high electrical costs.

DormGrow G8LED 450 Watt Coverage

When growing cannabis indoors – efficiency is key. One of the crucial components to maintaining or increasing efficiency is by utilizing the proper LED to cover your plants.

If your outer plants receive less light than the plants in the middle – then the system is inefficient. However, the G8LED 450W Veg/Flower LED system covers 2.2㎡ or 24 sq.ft., which is adequate for up to 9-medium sized plants.

This is ample coverage for most home cultivators, which makes this LED system incredibly efficient for most growers.

The 90W Flower Booster LED has a maximum coverage of 3 ft. by 3 ft., which is surprisingly large for an LED that only draws 80W from the wall.

Who is the DormGrow G8LED 450 Watt For?

Ultimately, DormGrow’s G8LED 450 Watt Veg/Flower and 90W Flower Booster Kit is perfect from home cultivators that are growing between 4-12 plants.

Of course, this number can be greatly increased by adding a second Veg/Flower LED or additional Flower Boosters. It performs exceedingly well within confined spaces and is as easy-as-it-gets when setting up.

Each of these LEDs is dead-simple to start using because they are stand-alone units. All you need to do is to flip the switch and let there be light.

DormGrow G8LED 450 Watt Competition

We know that Dorm Grow’s G8 LED series aren’t the only LEDs on the market. However, after searching far and wide, only a few come to mind.

The competition for the G8LED 450-watt Veg/Flower LED system is Viparspectra Reflector-Series 900W, PlatinumLED Platinum Series P900, and the Kingbo 900-Watt LED.

After comparing and contrasting each of these 900W LEDs, the G8LED 450-watt Veg/Flower LED system remained on top because of its ability to produce a sky-high PAR rating of 1,500+µmole.

The 90-watt Flower Booster, on the other hand, generates 770µmole and leaves the competition behind.

Expected Yield From the DormGrow G8LED 450 Watt

Ultimately, the G8LED 450-watt Veg/Flower and 90-watt Flower Booster Kit will produce the maximum amount of flowers that a strain is capable of.

Yield is not entirely reliant upon lighting because water, nutrients, and other environmental factors play a significant role in the final

Each of these LED systems provides adequate lighting to allow your genetics to strive to the best of their ability, which should result in an abundant yield – time after time.

After spending countless hours viewing the DormGrow G8LED 450 Watt Veg and Flower plus 90W Flower Booster kit – our only gripe was the price.

However, even if the price falls in line with competitors, this kit’s features are too good to pass up.

Overall, this LED kit surprised us with its intense lighting at a fraction of the electrical output of traditional HIDs and cutting-edge plasma lighting.

We found that growers, from beginners to professionals, can easily transition over to this LED system because it’s so easy to use.

Aside from the small dent in your wallet, the DormGrow G8LED 450 Watt Veg and Flower plus 90W Flower Booster kit are well worth your time.

It’s no wonder why DormGrow offers such incredible customer service and a long money-back guarantee – you’re likely not going to be returning it any time soon.

If you’re on the fence or ready to make the jump towards LEDs, there’s no better option than making the move with DormGrow G8LED 450 Watt Veg and Flower plus 90W Flower Booster kit.
