Whitepapers & publications

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.

E.M.I A double-edged sword

The introduction of high frequency electronic remote ballasts into the market has created a new problem: electromagnetic interference (EMI). EMI consists of high frequency signals which are either conducted or emitted in the form of radio waves.

Calculating with light

It seems so easy. You have a few trays of plants, so what keeps you from just hanging a few lamps above them? If you surf the forums, people are really clear about how to do that - a 1000W HPS does a 4 x 4 space, right? Wrong.

LED's, A bright future?

Leds are the future"... How often have you heard that in the past few years? So, is the future already now, or are we getting there? Is LED the new "wonder light", or do we still have to learn to appreciate LED?

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.
