Black Dog LED Grow Light Review (Phytomax-2) 800- Including Pros and Cons

The Black Dog LED 800 is so named because it draws about 840 Watts of power. Black Dog has been very upfront about its capabilities, making sure the consumers know what the product is all about.

Let’s dive deep and elaborate the specific details of the Black Dog Phytomax 600 LED.

High Quality Diodes

While standard LED grow lights utilize 3 Watt diodes, the Black dog has equipped the Phytomax-2 LED grow lights with 336 newer, more efficient 5-watt diodes.

With higher wattage draw, the lights offer better canopy penetration and even light distribution without the light burns.

Using 5 watt LEDs will soon be the new standard as the 3-watt diodes lack the required punch for optical penetration while higher wattage diodes cause too much heat and reduce the lifespan of the LEDs.

60% More Light

The Phytomax-2 600 offers 60% more light than its predecessor Phytomax model. Black Dog achieved this feat by using better quality diodes and at the same time, removing the glass plate and thus reducing transmission losses.

The remarkable aspect is that the Phytomax-2 offers more light at the same wattage draw (840 watts).

Full Spectrum Light System

The Phytomax-2 800 LED grow light uses Black Dog’s patented Phyto-genesis Spectrum system. Black Dog claims that it is the most efficient light spectrum for growing plants and they’re basing this on over 6 years of research and testing.

Being a renowned LED manufacturer, it is a huge positive point for you as a customer as it enables a trust factor on the band and its products.

Black Dog also provides data sheets showing the capabilities of the Phytomax-2 and it is shown that the device outperforms HPS, MH, CMH, induction or fluorescent LEDs in equal wattage tests.

Efficient Heat Dissipation

Being an 800 Watt LED grow light, we can assume that the Black Dog Phytomax-2 exudes a lot of heat. However, a smart and innovative design by Black Dog has successfully circumvented this problem.

Using the biggest heat sinks in the industry and combining them with efficient long-life fans rated for 70,000+ hours the Phytomax-2 800 brings down the heat output to 2148 BTU.

Well, full spectrum lights have a huge advantage over the conventional lamps and HID lights as they dissipate fairly less heat and helps your grow room to stay cool.

For those unfamiliar with the terms, the heat produced is significantly low for such a high wattage device.

Primary Optics Use

The Phytomax-2 800 uses primary optics in its diodes. While other companies frequently rely on secondary optics to ensure light distribution is well achieved, Black Dog opted to move in a different direction by using just the primary diodes.

This resulted in a higher light generation and an even footprint throughout.

Edge-to-edge Coverage

The Phytomax-2 800 demonstrates perfect light distribution throughout its entire spectrum while accommodating a large coverage area.

Black Dog offers detailed spectrum reports of PAR values and PPFD numbers at specific distances to its users. Experts can utilize the detailed reports to utilize the product in the most suitable conditions.

If these features don’t sway your mind, the Phytomax-2 800 LED grow light from Black Dog contains a few more nifty features tucked in. It is no wonder the product is getting rave reviews and thumbs up in acknowledgment everywhere. Here are a few more specialties you’ll find in the Black Dog Phytomax-2 800 LED grow light:

Hand picked diodes

The Phytomax-2 800 grow light uses diodes sourced from two different companies.

This goes to show that they’ve handpicked the most suitable LEDs for their particular wavelength range and have ensured that maximum quality of the product is delivered.

Spectrum Advances

The Black Dog Phytomax-2 opts for a single spectrum lighting system which they have optimized using a variety of means.

Light in the blue wavelength has received a profound boost compared to its previous generation thus, directing plant growth more efficiently than before.

Side Mounted Cooling Fans

The cooling system apart from using quality products also features design innovations. With side mounted cooling fans, the cooling not just occurs rapidly, but also it affects the setting up of the device in a positive way.

First of all, powerful cooling fans mean that you would have to use less number of external exhausts. Since the cooling fan of the Black Dog LED is quite good, you should not need an external fan for dissipating heat from the grow room.

Build Quality And Use

The Black Dog LED Phytomax-2 800 is a sturdy, well built LED grow light. With the exclusion of the fragile glass pane covering the front portion of the device, the Phytomax-2 is better suited to handle a tumble now more than ever.

With a price at par with the standard 800 Watt LED grow lights in the market, the Black Dog Phytomax-2 does offer a lot more features than its competition. Let’s dive in a Pros & Cons list to see where this product truly stands!

  • Top quality high end 5 Watt diodes (336) providing 60% more light than the already amazing Black Dog Phytomax series.
  • Improved full spectrum lighting system on the already amazing Phyto-genesis Spectrum system, with increased blue wavelengths to better direct plant growth and produce a better yield.
  • Large and efficient heat sinks with an advanced cooling system thanks to the top quality fans.
  • Well built and strong product without the flimsiness of the glass pane and efficient side placed fans.
  • Hand picked diodes sourced from different companies as per their characteristic strengths.
  • Well rated (50,000+ hours) LED grow light, capable of performing for up to 10 years.
  • The high power means the grow light can’t be too close to the plant.
  • Single spectrum system doesn’t allow spectrum control for various stages of the plant cycle. Thus it loses out on energy savings during the vegetation stage, however it promotes rapid growth.

If you’re thinking about the number of cons, fret not. It’s only a fool’s errand to chase the perfect product, but the Black Dog Phytomax-2 800 LED grow light sure comes close. If you observe closely, the cons themselves come with its set of advantages.

With a 60% increase in light at the same wattage, high quality 5 watt LEDs, a true full spectrum lighting system and an advanced cooling with an innovative design, the Black Dog Phytomax-2 800 truly does have it all.

Having a price point similar to other 800 watts grow light systems makes it very tough for the competition to succeed. The Black Dog Phytomax-2 600 LED grow light is one of the most efficient lighting systems available for indoor growers.
