The PhytoMAX-2 400 from Black Dog LED is a powerful LED grow light that outperforms any LED of equal or lesser wattage on the market. It gives you a true full-spectrum light and has been newly designed for better light delivery and heat dissipation.

It uses only the highest quality top-bin LEDs. It comes with a 90-day no-hassle return policy, so you can do your own side-by-side comparison.

 

Black Dog PM-2 400 Quick Summary

  • replaces a 600w HPS, but with better yields and higher quality flowers
  • uses only 420 watts, but easily beats a 600w HID system
  • 168 top-bin high-output 5w LEDs  deep canopy penetration and even coverage
  • 4.25' x 4.25' flowering footprint — larger than a 600w HID light
  • best heat management in the industry — only 1432 BTU, far less than 600w HPS
  • true full spectrum from UV-A to near IR (365 nm to 750 nm) — perfectly tailored for plants' needs
  • pays for itself within a year due to more output at lower cost plus higher and better yields
  • 5-year warranty and a 90-day return policy — removes purchasing risk

 

Equivalent to a 600 Watt HID System

The PhytoMax-2 400 produces a superior yield to a 600 watt HPS bulb with higher quality flowers. At the same time, it saves you money on electricity, cooling equipment and the cost to replace bulbs and reflectors.

 

More Intense Light for Deeper Canopy Penetration

This fixture has 168 high-output 5-watt LEDs that deliver an intense light, which is necessary for deep canopy penetration. The light is delivered evenly throughout the coverage area, eliminating hot spots and leaf burn.

The LEDs used are the best manufacturers in the industry for each individual wavelength, including Cree, Osram, etc.

 

Outperforms Any Comparable LED Grow Light on the Market

The PhytoMax-2 400 delivers 840 LED watts, with an actual power draw of 420 watts. It outperforms any other 400 watt LED plant light.

 

Largest Proven Footprint of any LED Grow Light

Independent spectroradiometer testing has proven that the PM-2 400 footprint is the largest on the market. At the same time, it achieves an evenly covered footprint, meaning no hot spots. You won't have to worry about leaf burn.

Industry's Best Heat Management Maximizes LED Life

This fixture is equipped with ultra-quiet fans that are rated for over 70,000 hours of use and the largest heat sinks in the industry. Black Dog lights have the best active heat management of all LED lights and the PM-2 400 only emits 1432 BTU. This is far less than the equivalent HID system. Low heat output is vital for maximizing the lifespan of LED diodes and for spectrum stability.

 

Most Efficient Spectrum for Growing Plants

Over 6 years of research and testing has resulted in Black Dog's Phyto-Genesis Spectrum™. It is a true full spectrum, with light ranging from UV-A to near IR. In numbers, it covers wavelengths from 365 nm to 750 nm.

This spectrum is ideal for all stages of plant growth. Using one spectrum throughout the grow cycle eliminates the growth stalling that occurs whenever you change the light spectrum mid-grow, such as switching from MH to HPS bulbs.

The Phyto-Genesis Spectrum™ targets photosynthetic (chlorophyll/carotenoid) peaks and also increases THC, CBD, terpenes, flavonoids, antioxidants/vitamins and pigmentation via the UV-A light. The inclusion of infrared light helps boost photosynthetic efficiency (see Emerson Effect).

In equal-wattage tests, this spectrum outperforms HPS bulbs, standard MH bulbs, light-emitting ceramic MH bulbs, induction bulbs, fluorescent bulbs and "white" LEDs.

Moreover, the Phyto-Genesis Spectrum appears white to the human eye, which means you can easily monitor plant health. If you've ever grown below a traditional pinkish LED light, you know how hard it can be to see problems and address them in time.

Fastest Return on Investment

PhytoMAX-2 lights are the best value per watt among all commercial LED plant lights. They are proven to achieve an average ROI of 6 to 12 months. This means the PM-2 400 pays for itself within a year.

 

Environmentally Friendly

This light does not contain the highly toxic mercury you find in all HID and fluorescent bulbs. This also means no fees for hazardous waste disposal.

 

Best Warranty in the Industry

Black Dog LEDs come with a 5-year warranty and a 90-day return policy. See the 'Delivery and Returns' tab above (below on mobile) for more.

 

Package Includes

This light ships with a standard US 120V 8-foot power cord (but it can also run on 240V) and free 8-foot adjustable metal ratcheting light hangers.

 

Some people love LEDs and some hate them. When you hear people complain about LED grow lights, you know they've bought a cheap Chinese-made light.

When you hear someone rave about the incredible growth and yields they're getting with LED, they've bought a fixture like the PhytoMAX-2 400.
