Subbed up on this one and wondering when and where these will be available?
They're sort of available now if you want to PM me.
I say "sort of" because I haven't properly announced them yet and a couple of boards have just been sent off for sphere testing (actually, it's similar to sphere testing but more accurate). I need to sit down when I have some time to collate all the specs and explain the reason why they were designed the way they were.
There was a run of 96 of these boards made here - they are designed and assembled in Australia - using Nichia and Seoul Semiconductor LEDs (PCBs manufactured in China to our specs). The first boards have gone out to those who originally wanted us to make them, so there are about 50 or so boards left, which will be sold to pay for all the time and effort that went into making them.
One issue is going to be sales outside Australia, as shipping will add to the cost. This may not be a problem for those in Europe and elsewhere, but it is hard to match pricing of other offerings in the US simply due to the cost of shipping.
This is not a commercial venture yet. If there is interest, there may be a second run. Otherwise, we've just made a bunch of flowering boards that we, ourselves, wanted, as they suit our requirements. Those requirements being dedicated flowering boards with lots of red and elevated far red, but a lower red:far red ratio, near-UV and some UVA for terpene expression, able to cover a 3'x3' footprint, able to be maxed out (good light coverage and heat dissipation), able to run off one driver - no multi-channels - and high CRI, which, apart from offering a better quality light and spectrum, allows us to see the natural colour of the plants for early signs of nutrient deficiency etc.
I really like those thermal proportions.
You can run it at 2/3rds power with no sink. Means that you only really need an alu sheet for sinking. What are the dimensions?
The dimensions are 415mm x 205mm x 2mm. They are quite robust. There are 450 LEDs in total. When paired, they form a square (415mm x 410mm with 30x30 LEDs = 900) which is designed to cover a 3'x3' area - a proper 600W HPS killer. But I am using four boards at lower wattages to cover a 4'x2' (two pairs) and will post my ongoing results soon.
You can run them as soft or hard as you like - the LED spacing, 2mm boards and matching heatsinks let you max them out at 225W each. They will run off all the common 48V and 54V "A" type drivers (54V B type, if you are using Mean Wells). You could run one board hard at 200W to cover each 2x2, or two can be run soft at 100+W each per 2x2, or you can run them hard again to cover a 3x3.
A couple of the guys wanted to run 6 boards with heatsinks over a 4x4 or 4.5x4.5, but it was actually cheaper to run 8 boards without heatsinks and get really nice, even coverage. There are no hot spots on the boards because the LEDs are all evenly spaced.
