More SPAM from Prawn (Psst - buy my LEDs)

Here's an MPG first - it' a new LED panel design that will directly replace a 600W HPS with 400W of high-red, high colour index, full spectrum (UV to Far Red) LED light that also knocks a week or so off flowering times.
Someone I know has been working on this design for some time now.
It's a 450 LED panel with high efficiency, high CRI diodes designed to run in pairs with a 380W driver to be a direct replacement for a 600W HPS.
The test PCBs arrived today and the boards will have the LEDs assembled on Monday. Designed and assembled in Australia, the LEDs are from Japan (Nichia) and Korea (Seoul Semiconductor). The PCBs are made in China, and will come with matching heatsinks as an option.
The PCB is 415mm x 205mm x 2mm aluminium. The LEDs combine the most efficient 3030 LED available on the market with a super-high colour rendering index (CRI 98) LED and a near-UV/UVA white phosphor LED to create a very balanced spectrum from 380nm (UVA to promote THC production) to 730nm (far red for the Emerson Effect).
All the LEDs are high CRI: 90-98 - creating a white light very similar to afternoon (warm red) sunlight. The overall temperature is about 3100K.
Each panel is rated to a maximum 225W (450W per pair), but can be dimmed down for better heat management and efficiency. They're designed to flower continuously anywhere from 100-200W per panel.
I know some of this is a bit technical, but the reason this is such a unique design is because it's the first to combine ultra-high CRI and UVA white phosphor LEDs with a high-efficiency LED that can all be run on one driver (mutli-colour panels usually require two or more drivers to run each channel).
It's also unique as it has been designed as a direct replacement for a 600W HPS - covering a 3'x3' to 4'x4' area. We've been running a lot of grows on LEDs lately using different spectrums and types, and have discovered we can equal 600W horizontal HPS yields with about 400W of LED, while the extra red also finishes plants a week early (speeds up flowering).
Even though HPS has a warmer kelvin rating of about 2500K or so, it has a lot more yellow and green spectrum light in it. High amounts of red accelerate flowering and increase bio-mass, whilst blue keeps nodes shorter.
High CRI LEDs have the benefit of more blue and red light, and less green light - whilst still being a true white light (3100K). They give plants a natural look under light, too, as CRI90+ is very close to sunlight (which is obviously CRI 100). That makes it easier to identify plant problems and health.
I'll have a running update of how this all progresses, but I thought you guys might like to be the first to know..
Any questions, fire away
