We've been a bit quiet lately because we've been working on some new lights and spectra that will be released over the next few weeks in the New Year. For those interested in what we've been doing here are some photos and details.
Some of you may have seen our new spectra in the UV thread, but I will post them again in case you missed them.
This is our new alround (mainly flowering) 3000K spectrum. The main differences between this and the current spectrum are the addition of a new Nichia 405nm UV diode in 3535 format and better CRI (up to 94) with some slightly better radiometric efficiency care of a new batch of LED Teknik 660nm monochromatic 3535 LEDs. The UV diode is mounted in place of some of the 660nm diodes on the board and replaces the PC Blue diodes (which were less than 50% efficient). The new Nichia 405nm is around 72% efficient and doubles the amount of UV on the board, which is now around 1%.
To make up for the loss of some of the 660nm diodes on the circuit board we added an old favourite: a Nichia 2700K CRI90 3030 diode that has a lot of red and far red in it and was the basis for the original High Light panels. We're the only horticultural lighting company to mass use these diodes, so we get the very best bins that clock in at around 2.75 umol/j – which is very high for a 2700K CRI90 white phosphor diode.
We've retained the Nichia Vitasolis 3000K, Nichia CRI70 5000K and custom LED Teknik 3000K narrow-band phosphor 3030 leds and that all means there is the same amount of red (over 50%) and a bit more far red (11.5%) on these boards with a similar amount of blue and slightly less green.
The High Light 420 spectrum has proven itself in grow rooms around the world, so we didn't want to change it too much, as it grows better than just about anything else we've ever seen. The Gen2 spectrum has the following improvements: twice as much UVA and significantly more violet light in the 400-420nm range; almost 20% more far red; very high CRI (94 vs 88 ); better radiometric efficiency (due to the highly efficient UV and more efficient 660nm diodes); slightly higher maximum power (48V at 5A for 240W)
This board has 420 diodes made up of the following:
90x 3030 Nichia CRI90 2700K
90x 3030 Nichaia Vitalsos 3000K
90x 3030 LED Teknik 3000K narrow band phosphors
90x 3030 Nichia CRI70 5000K
30x 3535 LED Teknik 660nm
20x 3535 LED Teknik 730nm
10x 3535 Nichia 405nm UV
Demand for a propagation and leafy green spectrum led us to develop another High Light 420 board with a higher Kelvin temperature. The above spectrum is 3400K and has more blue in it at the expense of some of the far red. The 2700K Nichias were dropped in favour of more Nichia Vitasolis and CRI70 5000K diodes, but the board retains the narrow-band LEDs and the same 3535 diodes, including the new Nichia 405nm UV. This board has even higher radiometric efficiency and a very high colour rendering index of 95 – which is perfect for propagators and commercial vegetable growers who need to see their seedlings and plants in a "true light".
Another of the commercial aspects of growing we wanted to address was to build a fully "hang and play" light – something that needs no pre-assembly. So we've come up with a new design for our 340-480W square fixtures (the old fixtures were 470W) that hide the wiring and eliminate all the rough edges, but still retain the same form factor and water-proof abilities.
It's not an earth-shattering design, but its simple and neat and of course it has some of the best LEDs on the planet matched to top of the line Mean Well drivers (and yes, we will still sell DIY kits in case anyone is interested). Please note that these are the old High Light 420 LED panels, not the new ones (photos to come).
The 340-480W Long boards will also get hidden wiring with the addition of a new plastic cover. They remain fully waterproof and all cosmetic changes can be retrofitted to any High Light 420 kit if anyone wants to update their existing lights.
Covers will fit these fixtures.
