A proper lighting system is an important factor for indoor cultivation. LED lights are considered the best cost-effective artificial light source that allows plants to produce more buds and flowers at high growth rates. These are much more energy-efficient when compared to standard halogen, high-pressure sodium (HPS), fluorescent or metal halide (MH) grow lights. ViparSpectra is a leading brand in the LED grow light industry with a long history of 10 years and its XS 1500 grow light is an excellent energy-efficient 2’ x 2’ grow light that just consumes 150 W. The dimensions of XS 1500 LED grow light are 14” x 10.8” x 3.0” and it carries only 5.62 lbs. Unlike traditional grow lights, LED grow lights can be specially tuned to the specific spectrum required for a specific growth stage.

LED Grow Light Efficacy Parameters
There are various other terms such as PAR, PPF, PPFD, voltage, photon efficiency, uniformity ratio, lumens, etc., which are used intermittently to describe the efficiency of LED grow lights. PAR represents photosynthetically active radiation and is usually located between light with wavelengths between 400 nm and 730 nm. The PAR value for the XS 1500 rises to 1470 at a hanging height of 12 inches. XS 1500 contains 288 LEDs of different 3000K warm white, 5000K white, 660nm deep red, and 730nm IR LEDs and produces full-spectrum light which is suitable for all growth stages of the plants.
Role of PAR in Plant Growth
The PAR band begins with the violet spectrum (380 nm to 450 nm). Light in this range is thought to improve flower color, potency, and taste and does not play an active role in the photosynthetic process. After that, the blue spectrum of light is between 450 nm and 495 nm, which is very important in the photosynthetic process. Light of this color is most often used in the sprout and vegetative stages of growth because it promotes the rapid growth and development of plants. After the blue spectrum, wavelengths from 495 nm to 570 nm represent the green spectrum of light. Plants absorb very little green light energy, but there are reports that small amounts can affect growth. The wavelength of yellow light energy ranges from 570 nm to 590 nm. Although of little importance in photosynthesis, yellow/red light promotes the emergence and is essential during the flowering period of plant growth. The final color of the visible light spectrum is red. It has wavelengths in the range of 620 nm to 730 nm. This light is needed during the flowering season. The efficient light spectrum of XS 1500 grow light can increase yield up to 50%.
Efficient Photosynthetic Photon Flux (PPF)
PPF, which stands for photosynthetic photon flux, is a measurement of photosynthetically active photons emitted from an LED grow light every second. PPF values measured in micromole/second (μmol/s) are the key to finding total optical output that contributes to photosynthesis. The ViparSpectra XS-1500 produced a usable PPF of 279.7 µmol/s. In addition to PPF, the effectiveness of LED grow lights also depends on a balanced spectrum, energy efficiency, and thermal management. It is also important to measure the amount of photosynthetic light produced by converting electrical energy into PAR photons called photon efficiency (μmol/J). The XS 1500 grow light has high efficiency up to 2.9 μmol/J. The ViparSpectra XS 1500 provides up to 50% higher real power and at least 70% higher PAR outputs than other manufacturers.
Calculation of Grow Light Efficiency
Grow light efficiency is calculated by dividing PPF by wattage. This is an important factor for large producers. PPF does not indicate how much of the measured light hits the plant (PPFD), but it is an important indicator in calculating the efficiency with which a lighting system creates PAR. XS-1500 gives an elite usable photon efficiency of 1.83 µmol/w. However, the light output of LED lights is not determined solely by the watt input. Instead, it depends on the quality of the component and the overall design of the specific optics used, drivers, LED chips used, chip density, heat sink, waterproofing, and so on.
Best-in-class Samsung LM301b Diodes and High PPFD
The XS series (XS 1500) features Samsung LM301b diodes, Mean Well driver, quantum board style fixtures, and ribbed aluminum heat sinks. Without an efficient heat sink, when the temperature of the electronic circuit board (backplane) containing the LED rises, the efficiency of the LED decreases significantly, so as the wattage increases, the efficiency of the LED decreases. In other words, an LED driven at 3 watts emits about one-third of the light of the same LED driven at 1 watt. Therefore, the challenge for growers is to determine the manufacturer of the grow light that provides the optimum light spectrum and light intensity to maximize profits. Different levels of light (PPFD) are required at each stage of plant development. The ViparSpectra XS 1500 produces an excellent maximum PPFD of 1470 with a 12″ suspension height.
Passive Cooling
Like other appliances, LEDs generate light and heat. The higher the wattage, the greater the heat, and the more cooling is required. Every watt produces 3.41 Btu of heat, which needs to be cooled. This is an important variable in specifying the electricity load of a facility and also affects the ongoing electricity rate. Therefore, just because a manufacturer sells high PPFD grow lights does not mean that they are the best grow lights for a growing environment. Also, placing the LED printed circuit board on an aluminum substrate allows heat to be dissipated towards or away from the plant, depending on how it was designed. Good heat dissipation is essential for long-term illumination during the different growth stages of the plants. The XS 1500 LED grow lights consist of an aluminum heat sink. It is designed to extend the cooling area to ensure good heat dissipation. Heat also affects in several other ways. First, the fixture’s thermal management system pulls heat away from the LED and dissipates it, preventing the thermal diode from failing prematurely. Second, the aluminum plate, the most common substrate on which LEDs are mounted, also helps to dissipate heat from plants. The XS series optimizes the cooling system by increasing the heating emissions by 30%, which significantly slows down the diode decay rate. The hottest temperature recorded on XS 1500’s heat sink was 59.2 oC. The XS-1500 is a fairly small light and is a very good option for the grower to get started on a small budget.
Flexible Dimmer Knob and Water Resistant Board
Light intensity is one of the most important measurements to know when comparing grow lights. However, it is better to have a certain degree of luminosity. If the light intensity is too strong, the tissue of the plant will burn. Another important function of LED glow lights is the ability to dimming according to the environment or specific physiological parameters to precisely control the PPF. The dimmer design of XS 1500 frees growers from complex brightness controls. It incorporates a dimming knob on the unit side and the growers have the liberty to adjust the light intensity from 5% to 100% brightness. Due to the different growing stages, this knob is very convenient for growers to operate on actual growing occasions. The IP 65 water-resistant board saves LED lights from any water splash damage.
Long Life Span, Fast Delivery, and Warranty
For all types of lights, the amount of light emitted (measured by lumen or PAR photon irradiance) decreases with use. The output of traditional incandescent HPS and MH bulbs decreases much more rapidly than LEDs. The life span of XS 1500 is 100,000 hours, depending on operating conditions and other factors. ViparSpectra offers a 3-year warranty, 30-day duty-free refund and returns, and fast delivery. Global warehouses of the company are built in most countries including the United States, CA, AU, and EU to provide better after-sales service. The company can ship the order in 1 business day.
