Photontek XT 1000W CO2 PRO LED grow light review

By Shane Torpey
Photontek 1000W CO2 PRO

This 1,000W LED grow light is the largest output fixture I have ever tested and is very impressive. Designed for experienced growers who want to push the performance of their grow area to the limit in terms of yield per square foot.

Photontek XT 1000W co2 PRO 

Overview

The Photontek XT 1000W CO2 PRO LED grow light is a high quality fixture, exactly what we would expect from this long established grow light company (Their parent brand Lumatek has been producing high quality grow lighting equipment for almost two decades). It is easy to assemble and hang, the finish is excellent and has all the features you would expect from a commercial fixture including:
  • High Efficiency
  • High quality LEDs (Philips Lumiled and Osram)
  • Control systems compatibility
  • IP65 (we room rated)
  • 5 year warranty

However this fixture has one goal in mind: increase the PAR intensity to levels about twice as high as was typical only a few years ago with High end HPS lighting systems.

 

Does it makes sense to push average PAR intensity to over 1,100 µmols/m²/sec?

There are two main factors driving this increase in what is possible:

As grow lights have become more efficient and heat output from their lights reduces. This enables growers to increase the average PAR levels higher and keep their environment and canopy temperatures within acceptable limits.

The technology and knowledge required to supplement CO2 to 3 or 4 times normal levels has become more accessible and affordable.

With normal atmospheric CO2 levels increasing average PAR intensity above about 750 µmols/m²/sec has a reduced return.

PAR intensity vs growth rate 
However increasing the CO2 levels in the grow to match the PAR intensity improves the growth rate when PAR intensity is pushed up to the highs of about 1,500 µmols/m²/sec achieved with the Photontek XT 1000W CO2 PRO
Average PAR vs growth rate CO2 added 
This LED grow light is designed to take advantage of these developments so growers can increase their yield per square foot 40% - 60% higher than achievable before.

Recommended Coverage: 5ft x 5ft (1.5m x 1.5m)

Physically big, just under 4ft x 4ft in size, this 10 bar LED grow light also delivers an average PPFD (Photons of PAR light) of over 1,100 µmols/m²/sec in a 5ft x 5ft grow area with an excellent light spread and very even coverage. This is 60% higher PAR intensity than the most efficient 1,000W DE HPS on the market can deliver in the same space with a much better light spread and about 40% less heat to be removed from the grow area.

 

Features

The fixture is very high quality in construction, easy to assemble and has on board dimming as well as connectivity to the Photontek controller system which can control multiple fixtures with all of the features any grower would need.

 

LEDs and Spectrum output

MIGRO Test results

The Photontek XT 1000 CO2 PRO was setup in our 5ft x 5ft test area and hung at 20". We took 100 measurements of PAR intensity (PPFD) on a 10 x 10 grid across the target area (simulating a plant canopy) with an Apogee SQ500 Quantum sensor. The target area was surrounded with highly reflective material to simulate real world performance in a grow tent environment.

The result is extremely impressive. The power consumed at the wall was 1,014 watts and the average PAR of 1,104 µmols/m²/sec in a 5ft x 5ft grow area means the Photontek XT 1000 CO2 PRO has a real world system efficiency of 2.45 µmols/watt (usable PPF/watt).

Value for money

This is a high quality and high performance commercial fixture and so it is not cheap. However an system efficiency of 2.45 µmols/watt (usable PPF/watt) will keep running costs down in terms of electricity and heat removal. A warranty of 5 years is exceptional and will give growers peace of mind when investing in this fixture.Photontek XT 1000W co2 PRO
