What is Sol-Skin?
We set out to take all the accumulated data on grow systems and develop a professional DIY product that meets some key characteristics
Control of the spectrum,
Balanced current load
Market leading LED Efficacy
The boards fully loaded are only 6.70mm high, add a 1mm alum plate as a basic thermal bed and we are at less than 8mm. this off course does not account for driver placement on a 1mm alum plate so if you’re not remote mounting that will affect your profile, however the intent with the low profile is to make it perfect for height restricted grows like small tents or tray systems for microgreens etc.
Spectral Control 3 Channels:
The boards can be configured with any range of led’s in the 3030 footprint (channels 1 and 2), so typically 2700K to 7000k in any ratio required within the constraints of 2 channels of 3030 footprint. The 3rd channel is the Cree XQE foot print and can be Deep Red, Royal Blue or any colour within the Cree XQE/A footprint as well as the new Cree XD16 Power led. The size of the PCB and quantity of led’s also provides for SRM (Spectral ratio mix) so that we could offer the 3rd channel with 1:2 or 1:4 mix of red/deep red/royal blue.
Channels 1 & 2
Also available with 3030 Full Spectrum Led.
We are also offering a 3030 chip in full spectrum as an option this could be a complete board or a single channel (Channel 1 or 2) These are white phosphor based provide a full spectral coverage from 380nm to 840nm
300mm x 300mm or 1ft square is a good balance of light spread for many applications, perfect for a 3x3 grow area, deep canopy penetration as both a horizontal or vertical light source, also a perfect retrofit product for lights that promised a lot but may have lacked the reliability needed for a hard-core grow facility, would make a great Mars Hydro upgrade
Channels 1 and 2 are designed for 48V operation and Channel 3(Deep Reds) 45V (48V if you want to use a Phosphor based led) so meets SELV safety standards
Many mid power led boards take the low cost approach(series/parallel structures) and provide no protection for thermal runaway or current hogging and often create variable light levels from board to board or even string to string, this is often the result of mismatched voltage bins or worse case, partial string fails which result in the strings re sharing the current load across the remaining strings meaning variable light levels and changing thermal dynamics on the board, Well designed heatsinks may account for such possible variations but if not the boards life may be reduced and will impact PPFD.
The Sol-Skin boards have resistive structures that remove this issue by balancing the forward voltage loads. This means if you have 1 or 4 boards in your build each led will be driven exactly the same and any led failure will not result in current sharing
LED Selection: Total Available 675 Leds
The Solskins use only market leading efficacy from the industry's biggest players.
- Nichia 220LPW 757 series in new V3
- J series 3030 leds from Cree
- XQE Deep red
- XD16 led available in whites from 2700k to 7000k. The S3 Bin in XD16 can deliver up to 385 lumens per led at 1Amp drive, so 99 pcs of XD16 alone can deliver 38000 lumens
