Key points of choosing grow lights for greenhouses

As the number of horticulture light brands on the market increases, the difficulty for growers in choosing the right product also increases. As lighting represents an important investment in the entire project, what are the key points that decision-makers need to pay attention to?

Making an informed decision
Electricity consumption is the main energy source for greenhouses/indoor growing. Many projects use the production and unit power consumption ratio as the output indicator. Then there is light efficiency: higher light efficiency means a more bountiful harvest, all other things being equal. Crucial is also to consider the ease of installation.

Convenient installation saves on man-hours and achieves the result of cost reduction. Control over the cultivation is another critical aspect: with dimming control, one can customize PPFD according to the project situation and growth stage. It is like letting "the chef master the heat accurately". Finally, there is the spectrum: the designing of the spectrum is the core technique of horticulture lighting. Dimmable spectrum and experimentally proven light recipe help to improve the quality of production and increases the competitiveness of growers.

“As a horticulture light manufacturer, HarveLite has concentrated on product research and development, now bringing to the market a highly cost-effective product: Solify Pro,” the team with the company explains. “With power 630W, the output reaches 1512μmol/J, which also means the efficiency reaches 2.4μmol/J. There are some brands on the market that use a lot of far-red light products that easily exceed 3μmol/J. Solify Pro’s 2.4μmol/J light effect is based on its full spectrum. In practical applications, Solify Pro can replace 1000W HPS one-to-one without changing the power supply system, bringing about a total of 37% energy savings.”

US Greenhouse Project Manager Jeremy White said: "Solify Pro is installed very easily. One worker can complete the installation. Supporting multi-light interconnection also brings great advantages to actual operation. Overall, it is a product that really easy to use."

HarveLite marketing manager said: "In our product application projects, the actual experience of customers is extremely valuable to us. In addition to the convenient installation, the appearance of Solify Pro is also well designed. With its dimensions engineered, it has the narrowest shadow(and therefore)it won’t block the crops from the natural sunlight. The passive cooling design brings highly efficient heat dissipation with minimized energy costs. It also avoids the high risk of malfunctioning by fan cooling. At the same time, Solify Pro supports different PPFD requirements. A variety of regular lighting designs such as 200, 400, 600μmol/m2/s can be achieved in the greenhouse. In addition, I believe that the 5-year warranty also provides the grower with more insurance and peace of mind."

Now, Solify Pro provides the following spectrum options, which synchronizes growth cycle and the demand for enhancement of flowering:

Afrimedi, a South African medical cannabis grower, applied HarveLite's Solify Pro in their 3000m2 indoor cultivation project. Full spectrum and flowering spectrum products are installed. When asked about the reason for choosing HarveLite products, the technique supervisor said: "Energy consumption is an important issue we are concerned about. The high efficiency dispels my worries. In addition, the dimming function is also very necessary. We can control the output according to the actual planting stage.”

“With an IP66 protection level, there is no need to worry about erosion. It also can be easily washed with a water gun. The patented passive cooling design (EU patent) helps to reduce energy costs remarkably. Solify Pro is more and more favored by commercial projects worldwide,” the HarveLite team continues.

“In addition to providing practical and reliable products, HarveLite also provides users with lighting simulation calculations and project design services. We help customers design the best lighting solution, including the number of fixtures and the light distribution and so on.”
