A grow light is an electric light to help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour, temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation (e.g. the germination/vegetative phase or the flowering/fruiting phase), and the photoperiod required by the plants, specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.

Grow lights are used for horticulture, indoor gardening, plant propagation and food production, including indoor hydroponics and aquatic plants. Although most grow lights are used on an industrial level, they can also be used in households.

According to the inverse-square law, the intensity of light radiating from a point source (in this case a bulb) that reaches a surface is inversely proportional to the square of the surface’s distance from the source (if an object is twice as far away, it receives only a quarter the light) which is a serious hurdle for indoor growers, and many techniques are employed to use light as efficiently as possible. Reflectors are thus often used in the lights to maximize light efficiency. Plants or lights are moved as close together as possible so that they receive equal lighting and that all light coming from the lights falls on the plants rather than on the surrounding area.

Example of an HPS grow light set up in a grow tent. The setup includes a carbon filter to remove odors, and ducting to exhaust hot air using a powerful exhaust fan.
A range of bulb types can be used as grow lights, such as incandescents, fluorescent lights, high-intensity discharge lamps (HID), and light-emitting diodes (LED). Indoor flower and vegetable growers typically use high-pressure sodium (HPS/SON) and metal halide (MH) HID lights.

Metal halide lights are regularly used for the vegetative phase of plant growth, as they emit larger amounts of blue and ultraviolet radiation. With the introduction of ceramic metal halide lighting and full-spectrum metal halide lighting, they are increasingly being utilized as an exclusive source of light for both vegetative and reproductive growth stages. Blue spectrum light may trigger a greater vegetative response in plants.

High-pressure sodium lights are also used as a single source of light throughout the vegetative and reproductive stages. As well, they may be used as an amendment to full-spectrum lighting during the reproductive stage. Red spectrum light may trigger a greater flowering response in plants. If high-pressure sodium lights are used for the vegetative phase, plants grow slightly more quickly, but will have longer internodes, and may be longer overall.

High-pressure sodium (HPS)

An HPS (High Pressure Sodium) grow light bulb in an air-cooled reflector with hammer finish. The yellowish light is the signature color produced by an HPS.
High-pressure sodium lights are a more efficient type of HID lighting than metal halides. HPS bulbs emit light in the yellow/red visible light as well as small portions of all other visible light. Since HPS grow lights deliver more energy in the red part of the light spectrum, they may promote blooming and fruiting.[10] They are used as a supplement to natural daylight in greenhouse lighting and full-spectrum lighting(metal halide) or, as a standalone source of light for indoors/grow chambers.

High-pressure sodium lights have a long usable bulb life, and six times more light output per watt of energy consumed than a standard incandescent grow light. Due to their high efficiency and the fact that plants grown in greenhouses get all the blue light they need naturally, these lights are the preferred supplemental greenhouse lights. But, in the higher latitudes, there are periods of the year where sunlight is scarce, and additional sources of light are indicated for proper growth. HPS lights may cause distinctive infrared and optical signatures.

Conversion bulbs
Conversion bulbs are manufactured so they work with either a MH or HPS ballast. A grower can run an HPS conversion bulb on a MH ballast, or a MH conversion bulb on a HPS ballast. The difference between the ballasts is an HPS ballast has an igniter which ignites the sodium in an HPS bulb, while a MH ballast does not. Because of this, all electrical ballasts can fire MH bulbs, but only a Switchable or HPS ballast can fire an HPS bulb without a conversion bulb. Usually a metal halide conversion bulb will be used in an HPS ballast since the MH conversion bulbs are more common.

Switchable ballasts
A switchable ballast is an HID ballast can be used with either a metal halide or an HPS bulb of equivalent wattage. Growers use these fixtures for propagating and vegetatively growing plants under the metal halide, then switching to a high-pressure sodium bulb for the fruiting or flowering stage of plant growth. To change between the lights, only the bulb needs changing and a switch needs to be set to the appropriate setting.

Today, we will dive into the extensive world of HPS grow light.

Gavita Pro 1000 DE Complete Fixture

This is one of Gavita Grow light series.

The Gavita Pro 1000 Double Ended is the most powerful and sophisticated indoor grow light available. In greenhouse areas where this unit is being used as supplemental lighting, it can cover up to a 10' x 10' area. If used as a primary light source, the Gavita Pro 1000 Double Ended fixture can cover up to a 6' x 6' area.

The fixture comprises of a ballast, reflector and lamp in one complete compact package. Made according to horticultural standards, the housing of the ballast is sealed.

Technology for high frequency electronic ballast
The high voltage lamp technology results in a better efficiency of the arc tube: more light for the same power (10–25% more than traditional single ended lamps)! These lamps are best suited for extreme high frequency electronic ballasts, creating a stable arc without acoustic resonance, assuring optimal output and a long lamp life. The smaller arc tube and outer balloon require the lamp to be nitrogen filled instead of vacuum, which prohibits it to be air cooled. Air cooling of the lamp results in lower lamp temperature, which results in sub-optimal light output, up to 15% less than specified.

Features & Benefits
Complete fixture
The integration of ballast and reflector results in a compact fixture.

Balanced fixture
The fixture is balanced, so it can be mounted by just two hanging points. This enables much easier installation by brackets from C-profiles for example.

Horticultural design
Our fixture is not a contraption of a remote ballast and reflector: it is a fixture designed as a complete fixture. The high quality white coating is durable and UV resistant.

More information
The high frequency ballast was specifically designed for the Gavita double ended HPS lamp, resulting in an accurate, optimal output, a stable burning lamp and a better light maintenance over time. The ballast is not suitable to run Metal Halide lamps.
The reflector is replaceable (we recommend to do this every year to two years) and there is a choice of replacement reflectors.

Conclusion

Now that you know what two HPS grow lights are superior available right now, it’s just a matter of considering which one fits your grow best.
