Thanks @ClockworkOrange, we looked hard as using the Synjets again but It just wasn't the best solution for a higher powered system. After simulation, testing and developing our heatsink/chassis design for a while we were really happy with the weight, the functionality and material cost and its definitely the way to go for LED lighting.
The optics we have developed are very unique, because the shape is rectangular doesn't mean the primary use are will be really rectangular. The optics are non-Gaussian almost like a projector. Yes, there will a slight elliptical pattern to the primary use area but we are talking about a few cm's longer than the width. Overall the unit is designed and best suited for covering square areas. We will have some simulations up on our site with the other photometric data before launch so it should all be clearer then.
Tested and past IP66, it also has galvanic corrosion and UV protection so its good for indoors or greenhouses and safe for misting an foliar sprays.
The top surface of the optic has a diffusive microstructure like the holographic diffuser but the secondary optics and the microstructure is a single molded component so there is no air gap like the HS1. The light intensity distribution is just as good as the HS1 but the transmission efficiency is much higher. This single stage holographic optic is going to be a game change for LED's and horticulture.
Power consumption is going to be 250w draw on the GN-Telos-0008
@68grasshopper It will be more of a volumetric approach we take with the GN-Telos-0008 for recommendations but to give you just a feel for it, at 60cm height above the canopy/target pane it covers 90cmx90cm with 0.6 relative uniformity which is really very, very evenly. I would say for autos one unit per square meter would produce really good and efficient results. @TaNg and a few others on AFN and instagram are going to be running something similar area wise and there feedback to us and the community will be really valuable so keep an eye out for those threads.

In the basement mixing up the medicine
Magic I thought I would miss the launch details while on holidays in Spain with no internet. Logged on and bam there she is. What a beast I bet she makes good use of those 250w. And an IP66 grow light is perfect imagine these in an greenhouse with automated watering and misting. Can't wait to try one of these bad boys out, Sounds like you. Have betterd the diffusion. Are they still silent running? Which spectrum is more efficient Burple or warm white ? To clarify the warm white is better for flowering and penetration ? Burple for veg? Really excited to see it, can't wait to hang one of these beauties! Need to put in an order for that new tent! Congratulations GN exciting times
@GrowNorthern, i have a few questions, maybe you will find a time and will to shine a light on some of them 
First, let's compare let's say taller spaces (grow rooms, light houses, etc.) and smaller spaces (smaller tents, grow boxes, etc.).
And secondly, let's take some analysis of HS1's spectrum and white/red spectrum.
If i got everything right, HS1's spectrum is more cost per W - effective and is more suitable for lower grow spaces, where less power usage is very important due to heat, or simply bill for electricity needs to be always friendly. Is that right?
On the other hand, if this is a grow - room, or plant is more than 60cm height, i suppose other, white/red spectrum is better to reach bottom nugs, isn't it?
Am i right to think, that theoretically, i need a bit more W of white/red lights than HS1 spectrum if we are talking only about square space? If so, how much more, at least approx. in %?
How about far - red (730nm), are this wavelenght used in either of spectrums?
Would you recommend to hang some kind of cooler to move air thru radiator more actively? Interesting, what would be a difference in temps in both cases.
Also am i right to suppose that bicolor option is best in light houses as add-on to solar light, not for indoor use in general?
Hoping that these are not too much to ask, just thought that someone may use this info to understand better what they need and which spectrum / model to choose.
Nice classy unit, you were totally right to choose convectional cooling, it fails to fail ever and these lights will work for their owners like no other. Already imagine these thick copper mcpb plates and highest quality components!

Hi @Bunny thanks for your nice comments. Regarding the noise, there is no fans, no moving parts so no noise at all.
Regarding the spectrum, the major difference between the HS1 and the new white spectrum replacing it is replacing it is the ratio of green to blue. We wanted to produce a working light that was also very efficient. The increased green from the white LED's does lower the application efficiency compared to using just monochromatic LED's however quantum yield efficiency between 450-615nm in much higher so more light between 400-700nm will be reaching the lower canopies through absorption and photon ejection. Again the new CREE LED's we are using are a big step up from the Rebel's so efficiency overall is improved from the HS1. Our second enhanced full spectrum will be mainly for flowering applications. This spectrum has reduced deep red and increased light between 450-615nm so that more light reaches the lower canopies.
Attached below is a measured spectral power density of the HS1 (on top and in colour) and below that the 2 new enhanced white spectrum's in green. Sorry for the quality of this image but these are just what we have been working with for comparison and they won't be the final versions/measurements we put up on the site but they should give you a good idea.

@HolyTHC I am not sure I entirely follow, let me know if this doesn't answer it; The new enhanced full spectrum based on the HS1 (I am going to just refer to that version "HE") is the most efficient of the two new full spectrum variations when considering umol's/joule. It is the best variation to use for most applications. The second variation (I am going to just refer to that version "QY") is for achieving a higher consistency of results in flowering with dense canopies. For most applications the HE version will be recommended. The QY version will be more useful to growers with separate veg and flower rooms. Both HE and QY have a percentage of far red similar to the HS1 as the white LED's used are high CRI but no dedicated far red LED's. Looking at your current grow with the IR sunsets I would say introducing some 4000k-3500k LED's would improve the results but so would angling monochromatic LED's into the canopy/ using side lighting. The Telos line is top lighting only and the HS1 could be top or inter-lighting. This again is why we reassessed the spectrum's we were using.
No for most deployments, the heatsink will work based on your ambient air temp and heat will naturally convect away sufficiently to keep the light running optimally. Like any light we recommend a good intake and outtake for good air movement and also to keep temperatures under control in hotter months. If space is very limited, kind of like your current area, moving the air in and out would be more critical to keeping the grow room at the right temps for your plants and the light but the intake/outtake doesn't need to be over the Heatsink.
Yes, exactly is only for specific applications.
No worries at all, the thermal tech on the MCPCB is new and improved and I will post about that soon enough.
@GrowNorthern, thank you for explanation, you did gave me needed answers and i now understand well, what are these spectrums for and what configurations should be used where..
You really took this all new model research well, did targeted wide range of applications, that makes your lights even more interesting.
Good luck with your new lights and i can't wait to see these details on thermal tech, of real northern quality!

Once again @GrowNorthern I tip my hat Looks like an incredible new product.
My questions are far less tech and more practicality ....
I'm in a very low loft space - I've been using ms006 effectively angled sideways (angled as best possible to work with my 1m height limitation). Far from ideal - but I've been pretty successful up until now.
You say thislight is top lighting only - does that mean it can't be hung at an angle like my 006
Second question- since most growers on here are auto specialists and have effectively ditched the veg process /heading straight for bloom cycle- do you think the QY model of the unit might make more sense??
Thanks for the detailed response to all these questions so far - enlightening stuff
Cheers !!
