Photontek XT 1000W CO2 PRO LED grow light review

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 


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.
Photontek XT 1000W co2 PRO has onboard dimming as standard 

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.



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.

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

Good afternoon.i was deciding between the Photontek 1000w CO2 pro or the Fohse Aries(prefer the Fohse A3I +plus if I can find one and afford it.the Aries seems to be thevA3i +plus with 4 light bars instead of 6) I’m on disability due to a spinal injury that occurred while I was a marine mechanic and we are on a very tight budget so I want the hands down best light made.i can’t afford to need to upgrade in 3 years so I just need to bite the bullet and get the best.i would also like best be able to do a sunset/sunrise dimming and any other features you thing ate a must willing to buy scratch and dent,open box,ect to save money.cheapest i have found photontek 1000w co2 pro is $1390.00 the Fohse A3i +plus $2100.00.,I forget the cost of the Aries fohse.maybe $900.00.
My pics
#1- Fohse A3i + PLUS w/optional controller
#2- PHOTONTEK 1000W CO2 PRO w/optional controller
#3-Fohse Aries w/controller
#4- photontek 1000w PRO w/controller.if you would please let me know the Best out of these in the order you believe is best.their are just so many light manufacturers and they all say their the best and their are no more articles on canabis lights,sustems,nutrients, ect that are written honestly anymore.they all ate trying to push you to but something so they can get a tiny peice.but what these "experts " don’t realize is…I would be a loyal shopper of their site if they were honest.and said said yes I sell all of these lights but this one is best and honestly don’t buy this,or I don’t carry this but it’s actually the best…..however customer service has left the building…thanks for your time and consideration/Honesty-Bradley

Best Co2 meter/controller?
Titan 3
Titan 8
Titan 9
And use the Titan vo2 regulator to hook to tank or is their a better manufacturer?
