Invisible Sun Guide

Invisible Sun LED boards are designed to meet the needs of any indoor garden either as a supplement lighting using our variety of kelvin ranges or more commonly as a stand alone light for full spectrum, full cycle growing.
The diodes we use produce diffused full spectrum white light, we offer a range of temperatures to tune to your requirements from 2700k up to 4000k and above.
You can find the technical documents both the Samsung Lm561C and Lm301B here and here respectively. Also you will  find a link here to Samsung's white paper on the benefits of White Light LED usage in horticulture. 

How many boards or Kits do I need for my Space ?

Invisible Sun advise between 22w - 35w per square foot as a general guide line as to the amount of light required.

Below is a general guide of coverage for each kit and board

ISH135 covers up to 2.5ftx2.5ft for flower 3ftx3ft for veg

ISH150 pro covers up to 2.5ftx2.5ft for flower 3ftx3ft for veg

ISH250 covers up to 3ftx3ft for flower 4ftx4ft for veg

ISH265 Pro covers up to 3ftx3ft for flower 4ftx4ft for veg

2 x ISH250's or 265 Pro's will cover up to 4ftx4ft for flower

4 x ISH250's or 265 Pro's will cover up to 4ftx8ft for flower

8 x ISH250's or 265 Pro's will cover up to 8ftx8ft for flower

Which driver should I choose ?

Invisible Sun boards are the same principle as cobs, wired in either series or parallel. firstly you need to decide if you are running a constant voltage CV driver for parallel wiring or a constant current CC driver for series wiring.

Warning - If you are not familiar with DIY lighting/electronics and making a secure connection then opt for series wiring and a CC constant current driver.  

Example - Each ISH288 board is 48v, when 2 boards are ran in series you will require a driver that can fit 96v into its output voltage. This is the sum of both 48v boards added together. Driver suggestions below, these are just guides and not the only drivers that work.

Note - When packaging drivers with full lighting kits Invisible Sun LED only use Meanwell Branded drivers. A link to Meanwell is here where you can find the technical documents for all of their drivers.

HLG 480H C2100 A/B @ 500w

Important note _ Drivers are not always readilly available in all territories, when full lighting kits are purchased by the customer a suitable driver from the above list will be supplied.

How to wire your Invisible Sun boards in series ?
Either follow the image for wiring, (tip) make sure your boards are facing the opposite way.
to each other for easier wiring.
Or watch the quick assembly video below

Wiring 4 boards in series (ISh120 pcb / ISH150 pcb)
Parallel wiring driver options with ISH Pcb's (ISH120 pcb / ISH150 pcb)
We use Molex connection on our ISH288 boards and Wago on the ISH120's 
For connection wire we recommend 300v rated hook up wire, either solid core or flexi. 1mm /1.5mm /2mm 
Avoid using general house wiring

Warning -
If using flexi / stranded wire, solder / tin the end of your wire for a better connection.

To extend your wire lengths we supply either Wago 221's or 222's with each full lighting kit.
