We understand we have a large number of options and configurations of lighting systems, so here we will explain which lights are best suited for which spaces and requirements. 

So when choosing the right light you should consider the points below so that you can find a light which has the right power intensity and coverage for your required space.

  1. The floor space you are trying to light in Square feet

  2. The height of the grow room or headroom

  3. Preferred Watts per square foot (30w psf is optimal)

  4. Growing method 

  5. Is corner to corner coverage important to you ? or is a central light suitable ?

Once these points have been established you can get a better understanding of which lights would be suitable for your grow room.

The single most important of the above points is to establish how many Watts of light you will need for your room, below is a grow room calculator. Simply input your grow room measurements to gain your square footage , then input the square footage in the bottom section and select whether you want 30w per square foot or 35w per square foot and the calculator will give you the total watts needed to light your space.  

Below the calculator are a list of our lighting systems and the spaces they will cover.

 Ok, so now we have our square foot space and required wattage,  as an example we will go with 16 square feet and 480w when calculated at 30w per square foot.

Below you will find a list of lights by coverage and wattage. The ideal light in this scenario would be the ISH530 suited for a 1.2mx1.2m (16square foot) 

Which board type ?

Ok so we what lights cover what spaces and at which wattages,  next we look at which range is suited to your requirements.  

type R trigger the Emerson effect to increase plant metabolism, speed up growth rate, maturity and flowering cycles. By using deep and far red together reap the benefits of all of the above with no loss of yield. Great for scrogging and lolli popping 

type BR is similar to the type R in that they use deep and far red, but with the added addition of 450nm royal blue, this will reduce stretch and give an excellent structure to your plants. bushy and stocky. 

So with that all in mind you should be able to choose the perfect light for your set up.
