Horticulture lighting

The BLV brand has been an established name in the field of horticultural lighting for almost two decades, and its HORTURION® HPS lamp series as well as our power supplies enjoys a worldwide reputation. With undiminished intensity and great success, the company continues to invest in the research and development of conventional lamps: In 2020, with the BLV HORTURION® intense, we were the first company to launch an HPS lamp with 1150 W / 2400 µmol/s output. This was followed in July 2021 by the world’s most efficient 1000 W HPS lamp with 2180 µmol /s light output: HORTURION® HPS 1000 W DE EL supra plus.

We have also significantly expanded our production capacities to meet the increasing demand for conventional greenhouse lighting. In 2017, a new and state-of-the-art production facility was inaugurated at our sister company Ushio Poland.

Customers from a wide range of growing sectors, from vegetable and flower farms to cactus growers, trust the quality and performance of the BLV HORTURION® series.

The growth of courgette under different light spectra

More information

HPS lamps have shown proven benefits as grow lights in the last 30 years. Their colour is richer of red and far red light which stimulates elongation growth and optimised fructification.

In a nutshall: HPS lamps are advantageous if you want to:

  • promote photosynthesis
  • improve growth
  • increase yield

However, there are many crops and growing methods where it is also advantageous to use MH lamps.

The main difference between metal halide and high-pressure sodium lamps is their colour spectrum: MH lamps have a higher amount of UV and blue light and less red and dark red light. The higher amount of blue light strongly suppresses elongation growth and ensures a rapid reproductive phase.

UV light stimulates the formation of anthocyanins and polyphenols, two plant pigments that enhance leaf and blossom colour.

In addition, the MH lamps’ colour spectrum is much closer to that of sunlight, resulting in significantly better colour rendering.

At a glace: MH lamps are advantageous if you want to

  • encourage compact growth and blossoming in decorative plants
  • enhance leaf pigments in coloured vegetables (e.g. lollo rosso)
  • make shrubs more resistant
  • enrich secondary metabolites in the pharmaceutical and cosmetic industry

It’s not an easy task to define the best solution. BLV will consult you on all aspects and will help you to find the lighting solution that really fits your needs.

The light output of a high-pressure sodium (HPS) lamp is the key element determining its efficacy.

For a long period of time the output of a 1000 W HPS lamp was restricted to 1950 µmol s-1. The reason for the restriction was the gas pressure inside the burner and the technology used to ignite the lamp.

In these lamps the ignition current ran from one electrode through a conducting strip in the ceramics to the other electrode. The necessary flow of current from the electrode to the strip established a limit on the gas pressure inside the burner. Once the temperature was high enough the gas inside the burner ignited; the lamp glowed.

Some years ago, a new BLV HORTURION® lamp was launched, which pushes the output from 1950 µmol s-1 to 2100 µmol s-1. By emitting 150 µmol s-1 more than a common lamp (+7.7 %), the BLV HORTURION® 1000 W HPS sets a new benchmark in regard to efficiency. The technology is a quantum leap towards cost efficient high density production.

This new lamp generation was made possible through optimization of the gas pressure and the co-development of a novel ignition technology: the HORTURION® triple capacitor.

The triple capacitor directs the ignition current not only to the electrode but also directly to the strip. Once the gas is ignited, the triple capacitor closes the connection to the strip and prevents flow of current through the strip. Disconnecting the strip during operation is essential because a constant electric field would enable sodium atoms to diffuse through the ceramics. Diffusion changes the chemical composition of the gas in the burner, leading to early failure and a reduced light output.

Due to the triple capacitor technology the gas composition in the burner is constant. The stability of the gas composition in the burner reduces the light depreciation and guarantees the maximum light output throughout the life time of the lamp.

In thousands of tests the HORTURION® triple capacitor has shown reliable ignition, high light output and stable gas conditions inside the burner. Hence, the HORTURION® triple capacitor guarantees greatest reliability and very high output for the entire service life, making the BLV HORTURION® HPS one of the most efficient and most stable HPS lamps currently available.
