Lumatek ATS300W Pro - First look and comparison


Having been on the market now for nearly 2 years, providing hobby growers with some great results, the Lumatek Attis range of LED grow lights is now an established, tried and tested recipe for successful small scale LED growing.

Lumatek have decided that it's now time for a fresh design; building on the same recipe as previous Attis models but with improvements in efficiency and some updated features.



The prettiest just got prettier!

Don't be fooled into thinking that these gorgeous lights are all style over substance.... Lumatek have engineered some significant improvements that increase both performance and longevity over the standard models. Let's run through them.


Conformal Coating

As with the recent upgrades to the Zeus 2.9 versions (you can read that blog post here), by replacing the hard lens cover with a clear silicone coating, more light can now pass through from the diodes, meaning less light is lost and converted to heat before its had a chance to reach the canopy.


External dimming

While both of the previous Lumatek Attis 200w and 300w were dimmable (in 25% increments), they had to be done from the fixture itself, as the knob was integrated within the light's housing. Again, in-line with the larger Zeus range, the dimming knob connects externally and can be situated and controlled from outside of the grow space; allowing growers to avoid light glare upon opening the tent/cabinet - protecting eyes and maintaining discretion.


Higher diode bin

By selecting higher bin LEDs and rearranging the trace design in a way that spreads these diodes out better, Lumatek have created a fixture that not only provides more light per watt, but also distributes this light more evenly.



PAR Maps

We've been able to carry out some comparative PAR mapping between the original 300W ATS (Attis) and the new Pro version, so you can see just for yourself the improvement in spread and output that's been achieved.

We used an Apogee MQ-610 and placed each light over an enclosed 90cm x 90cm area, using a 8x8 grid to plot out our measurements:


ATS 300W 2.3

ATS 300W Pro 2.7


As has been stated before on previous blogs: as well as providing you with a PAR map so that visual comparisons can be made between the two Lumatek versions, we think it’s useful to quantify these differences as best as possible and compare our results with the official specifications. Bear in mind that while our Apogee quantum meters are incredibly accurate and the perfect tool for assessing real-time usable light distribution, their limitations should be included within the range of variables that could affect the difference in the numbers we see (including input voltage, power consumption, ambient temperatures, human positioning error etc). With that being said, the deviations are small enough (5-10%) to provide a more than acceptable reference for comparison.

So with that out of the way, let's break down the numbers we're seeing.



Crunching the numbers

Let’s look at the difference when we total all PPFD numbers taken from each PAR map:

ATS (Attis) 300w 2.3 - 46650
ATS 300w Pro 2.7 - 55010

Difference between - 18%

Now let’s compare the difference in PPF (that’s total light output) between the two, as stated by Lumatek:

ATS (Attis) 300w 2.3 - 690
ATS 300w Pro 2.7 - 816

Difference between - 18%



So it is worth the extra money?

In our opinion, yes! With this being the largest efficiency improvement to-date that we've seen within a Lumatek range, those currently in the market for a 300W LED grow light will be hard pressed to find a fixture that matches the ATS300 Pro in both output and spread. While it's certainly possible to find cheaper 300W lights out there, those wanting the absolute best results out of 80cm x 80cm - 1m x 1m spaces, will certainly appreciate the consistent year-round performance provided by a fixture like this.
