High pressure sodium lamp spectrum mainly yellow light output, apply to blossom and bear fruit stage can also be used for all plant growth stage
High pressure sodium lamp when using a white gold, have high luminous efficiency, less consumption, long life, light color is good, strong ability to penetrate the fog and trap, the advantages of color temperature 2100 k. Widely used in road, highway, airport, port, dock, station, plaza, street interchange, industrial and mining enterprises, park, garden lighting, and plant cultivation. High color rendering of high pressure sodium lamp is mainly used in the gymnasium, exhibition hall, amusement parks, department stores and hotels and other places lighting.
Start the feature
High pressure sodium lamp starts, in the initial stage is mercury vapor and low-pressure discharge of xenon. At that time, the light bulb working voltage is very low, the current large; To continue with the discharge process, the arc temperature rise, mercury, sodium vapour pressure is decided by the discharge tube cold end temperature, when the discharge tube cold end temperature to achieve stability, discharge will be stable, bulb of luminous flux, work voltage, current and power are in normal working condition. Under normal working conditions, the whole process takes about 10 minutes.
Working circuit system
Working in high pressure sodium lamp circuits in addition to the light bulb, also must be trigger high-pressure sodium lamp inside or outside the trigger high-pressure sodium lamp respectively the corresponding work of circuit, such as light bulbs + electronic ballasts can meet the needs of high pressure sodium lamp to work properly.
At any time of the year (except summer, of course), plants require special care in the form of additional lighting. Lack of light has a detrimental effect on the quality of their fruiting, general condition, growth rate and many other things. During these periods, experienced gardeners are wondering about purchasing and installing additional light. The choice here is quite large, but HPS lamps continue to be especially popular.
It will not be easy for novice gardeners to decide without outside help or prior preparation how to choose and where to buy a HPS lamp. Due to the special specifics of this coverage, it is worth approaching the issue comprehensively and trying to deeply and comprehensively understand the issue. We will look at the basics of choosing HPS lamps
Rules for choosing a HPS lamp
In order to understand how to choose a HPS lamp, you need to get acquainted with the features of its operation and design. Such lighting is usually used for grow boxes. Sodium lamps are a great way to quickly, efficiently and effectively grow crops.
DNAT has many advantages over its analogues:
- high efficiency of use;
- powerful luminous flux;
- large labor resource up to 20,000 hours.
How to choose a HPS lamp is directly influenced by the size of the illuminated area. This could be a greenhouse, a growbox, or a greenhouse. The use of HPS in a residential area should be careful, as they have high light output. It will be better if you install it indoors or on a loggia.
The presence of a large number of red rays in the color spectrum of HPS makes it an indispensable lighting during root formation and during the flowering period of the crop. To achieve maximum effect, it is better to combine HPS lamps with mercury and metal halide models.
The power of a 250 W HPS lamp, placed in a special lamp, can provide illumination of up to 15,000 lux per 1 square meter. This gives DNAT a lot of advantages and benefits:
- high ratio of light output to energy expended;
- HPS light is suitable for growing any plants;
- high demand and popularity;
- the existence of specially optimized models for growing various crops.
