We regularly publish white papers and contribute to magazines. These publications can be downloaded for your personal use. If you wish to use the information for a publication, reprint or to publish them on your website, please contact us first.

Whitepapers

In our white papers we explain specific technologies, products, applications or concepts that may seem complex at first, but are essential for understanding lighting or lighting products. We drill down to the essence of the issue and provide clear guidance. 

Plasma lighting

How to design an optimal growroom for your lights

Most people start with a room, and then ask a lighting manufacturer how to position their lights in there. Actually that is a bit the wrong way around: lights with specific reflectors have a very specific throw and field.

Plasma lighting

Plasma spectrum for use in combination with HPS lighting

Many studies have shown that full continuous spectrum with sunlight qualities is the best spectrum for healthy plant development.

EMI – A double-edged sword

Electro Magnetic Interference (EMI): What is it and should I worry about it? How does it affect my installation?
From: Garden Culture US 4

Supplemental Lighting

You cannot grow every plant succesfully just under HPS.
From: Garden Culture US 5

Calculating with light

One of the most common errors in grow room installations is the positioning of the lighting fixtures. Learn why.
From: Garden Culture US 6

Grow room design

Most people start with a grow room design and then position their lighting. That is not always an optimal approach.
From: Garden Culture US 7

LEDs – a bright future?

LEDs have come a long way since their first introduction. Overhyped, overpriced and underperforming at introduction, now a viable option… at a price!
From: Garden Culture US 8

LIGHT MATTERS 1

Quantity
How much light do you give your plants? And how does that matter?
From: Garden Culture US 9

LIGHT MATTERS 2

Quality and quantity
How does light quality and quantity influence your yield? Is there a “magic spectrum”?
From Garden Culture US 10

LIGHT MATTERS 3

Lighting rooms instead of plants
How would you like to get 25% more yield from the same light installation you have now? Stop spilling light!
From Garden Culture US 11

LIGHT MATTERS 4

The five most common errors
I don’t care what your buddy tells you: These are the 5 most common misconceptions about lighting and lighting plants.
From: Garden Culture US 12

LIGHT MATTERS 5

Compared to the sun…
What is the best light for plants? How does that compare to the sun? Common sense and the science behind it all.
From: Garden Culture US 13

LIGHT MATTERS 6

Ceramic Metal Halide lighting -
the definitive guide

So you are wondering about CMH, CDM, LEC? What does it mean? How does it compare? Theo Tekstra explains you the science and the hype.
From: Garden Culture US 15

LIGHT MATTERS 7

Lighting control -
To dim or not to dim

What is the purpose of lighting control? How can you use that to your, and the plant’s advantage?
From: Garden Culture US 16

LIGHT MATTERS 8

Lighting safety
There are loads of safety aspects to consider when installing and using high intensity lighting. Beware and be safe!

Typical applications for 750W lamps are vegetative rooms, combinations with plasma lighting, smaller rooms with lower intensity and rooms with a limited distance to the crop. 
Gavita was the first to introduce a 750W double ended lamp and fixture for horticulture, increasing the efficiency of single ended 750W fixtures by about 20-30%. They are now the standard in horticultural lighting for 750W systems. 
Gavita pioneered the use of double ended lamps in this industry. These professional lamps offer you the highest output and light maintenance in the market today. Backed by decades of horticultural experience, Gavita recommends these lamps for use in her professional fixtures in horticulture. 
Our DE lamps output 15-35% more PAR light than traditional single ended lamps and have a much better light maintenance, which means that you only have to change your lamps once a year. 
The double ended construction enables the arc tube to be in stable the center of your reflector, for optimal optical placement. No more sagging heavy lamps in your reflector that destroy the throw of your fixture.  The absence of a frame wire further increases the output and uniformity. 
The  narrow lamp reduces interference with reflected light from the reflector. It is nitrogen filled instead of vacuum, allowing the arc tube to be smaller while maintaining the correct arc tube temperature. You should not use our double ended lamps in direct air cooled fixtures, as they cool under the optimal temperature, reducing the output considerable. 
The smaller arc tube results in a higher light density than single ended lamps, improving the penetration of your crop.
Higher light output results in lower infra-red output, as energy in a lamp is converted to light and heat: The more light, the less heat is generated.

Always make sure that you run lamps at 100% for at least 100 hours to stabilize the lamps, before you dim or boost the lamps.
