Summary: BESTVA Double Chip Grow Light Series Review
We have analyzed the features of BESTVA DC 1000w, 1500w, 2000w & 3000w and reviewed their characteristics and performance in detail in the earlier portions of the review. This box summarizes our findings. above are given some of the Pros and Cons of the BESTVA DC LED grow lights, and below are our recommendations.
The BESTVA models in this review are high performing grow lights devices and by considering the Pros and Cons, we can easily analyze that they check most of the major requirements.
The full light spectrum is suitable for cultivation of plants, vegetables, and flowers. These are also low-priced devices as compared to their competitors.
However, the PPDF values at a height of 24” is low as compared to the competitors. In order to obtain greater light density, the coverage area will have to be compromised.
We recommend these BESTVA grow light models to medium and larger growers, since in those cases the suitable light density and required light spectrum will be available throughout the entire plant lifecycle. For smaller scale grow rooms you may find the BESTVA 600w more suitable.
Are you in search of a suitable grow light for cultivating your indoor hydroponic plants? If the answer is yes and if you have just started out looking, you may be bombarded by an inrush of information that you may not readily understand.
There is a huge variety of grow lights available in the market and while they may be suitable for certain conditions, not all of them may be suitable for reproducing conditions that you need. There are different parameters of analyzing the performance of a grow light i.e. light Spectrum, PAR, PPFD value, Energy consumption, etc. We will discuss below the performance of BESTVA DC series grow lights with respect to these parameters to assist the readers in making an informed decision.
BESTVA is among the most popular designers and manufacturers of grow lights for high-quality indoor cultivation of plants, vegetables, and flowers. BESTVA DC series grow lights are full spectrum grow lights, which are specifically designed to provide an advanced full light spectrum. It has been studied that the plant lifecycle consists of 4 different stages i.e. Germination, Vegetation, Pre-flower & flowering.
During these stages of the plant lifecycle, they need exposure to different wavelengths of the visible light spectrum for growth and nurture. In this review, we will analyze the full light spectrum produced by BESTVA DC series grow lights and determine if it caters to the basic needs of the whole photoperiod of plants growth or not?
Those lights, which have a better replacement index for HPS lights, are considered more energy efficient. BESTVA grow lights are available in different power rantings i.e. 1000W, 1500W, 2000W & 30000w having multiples of 10W dual chip LEDs. Below we will tabulate their respective, actual power draw and the HPS replacement index

Construction & Design
BESTVA LED 1000w, 1500w, 2000w & 3000w Review
BESTVA Dual Chip LED Grow Lights have a solid, compact and lightweight design, which complies with the international standards of quality and safety.
The outer panel of the grow lights is made up of Aluminum, which is a lightweight metal with an ultimate tensile strength of 290 MPa. This provides high strength and durability to the outer core of the panel.
The front face of the panel is made of glass through which light escapes into the surroundings. The base of the LED board is made of a reflective material, which focuses the scattered photons of light towards the coverage area.
Other grow lights: ViparSpectra Reflector Series
During the operation of the LED grow light, high-energy photons of light are produced and since the light has to be operational for a major portion of the day, there is a need for an advanced cooling and heating dissipation system.
There are 2-3 fans at the backside of panels of the grow lights of different ratings, which keep the system cool, and dissipate the heat energy into the atmosphere. Similarly, there are sinkholes at the back, sides, and face of the panel through which the heat radiations can escape into the environment.
Multiples of Dual Chip 10W LEDs designed and manufactured by Bridgelux/Epileds are installed in the panel depending upon the power rating of the panels i.e. 1000W has 100 LEDs, 1500W has 150 LEDs, 2000W has 200 LEDs and 3000 has 300 LEDs. These LEDs are distributed into different colors in order to produce a full light spectrum. The LEDs are oriented at an angle of 120o in order to achieve maximum coverage area.
The design and construction of the device complement its long life, which is estimated between 50,000 – 100,000 hours of operation. The grow lights are manufactured in a factory in China where every item is subjected to a 72 hours uninterrupted aging test and 300 current impact tests before being approved for usage.
Energy Usage and Efficiency
BESTVA LED grow lights are highly energy efficient as compared to reflective series lights, HID lamps and HPS lights and a comparison to this effect has been made in Table 1 above.
These lights produce low levels of heat while converting most of the electrical energy into wavelengths of photons having photosynthetic importance. The LEDs used in the panel are manufactured by EPILEDS having >95% power factor.
This suggests that only a minimal amount of electrical energy gets wasted as compared to conventional lamps having low power factors. The luminous efficacy of the lights is in the range of 60.14 lm/w, which is reasonably high. The device operates at an input voltage of AC 85V-265V and 50 – 60Hz frequency. The working temperature of the device is -68 – 104oF.
The Light spectrum of a grow light is the most important parameter of determining its suitability for indoor plantation. As stated at the beginning of the review, the plant growth cycle consists of different stages i.e. Germination, Vegetation, Pre-flowering & flowering.
All these stages require different wavelengths of light for proper growth and nurture. The light spectrum or the PAR Zone, which is most suitable for plant cultivation is 400 – 700 nm with little exposure of ultraviolet and infrared radiations as well. In the visible light spectrum, the two essential light wavelengths are Red Color (620nm ~ 660nm) and Blue Color (430nm ~ 460nm). The significance of different light wavelengths during different stages of plant growth is as follows:
- Blue Light: This part of the spectrum i.e. 430 – 460 nm, encourages the vegetation process of the plant growth. It also plays a significant role in root growth and intense photosynthesis. Blue light is often used alone during the early stages of cultivation.
- Red Light: This part of the spectrum i.e. 640 nm – 680 nm, encourages flowering and fruit production. It also plays a significant role in the stem growth process. When plants receive a significant amount of red light, they tend to grow in height in order to get more blue light.
- Most of the green and yellow wavelengths incident on the leaves are reflected, which give the plants their color, however, some portion of these wavelengths also play a part in the photosynthesis process.
BESTVA Dual-chip LED grow lights produce a full light spectrum having wavelengths ranging in between 380 nm – 780 nm. The dual-chip LEDs are distributed in such a way that all the important wavelengths are present during the entire cycle of cultivation. The most significant presence of wavelengths in the spectrum is those of Red and Blue color wavelengths. The relative intensity of blue light is around 1.0 while the relative intensity of red light is around 0.95. A small portion of purple (380 nm – 400 nm), Green (500 nm – 555 nm) and Yellow (555 nm – 610 nm) are also present in the spectrum.
Other: PlatinumLED Grow lights
This shows that all the important wavelengths of the PAR zone are available in the spectrum of BESTVA Grow light. However, another parameter for determining the suitability of the light spectrum is the PPFD values, which suggest the density of the actual light, which reaches the surface. PPDF value is inversely related to the height of the grow light from the surface. However, the height of the light is directly related to the effective coverage area. Therefore, it is expected that for the required coverage area, and a reasonable amount of light or PPFD value will be available for the cultivation.
According to studies, a PPFD value between 500-1000 μ mol/sec.m2 is required for the smooth cultivation of plants indoor. In the table below, we will look at the μ mol/sec.m2 value and the effective coverage area when the BESTVA Grow Lights of different ratings i.e. 1000W, 15000W, 2000W & 3000W, are hanged at a height of 24” from the surface:
The μ mol/sec.m2 values stated in the table above are for light density in the center of the incident surface and these values decrease as we move away from the center. We can see that the PPFD value for 1000W light is below 500 μ mol/sec.m2, which is considered insufficient for high-quality cultivation.
Similarly, the PPFD values for 1500W, 2000W & 3000W are in between 500-1000 μ mol/sec.m2 value but since the values in the table are actually the values in the center, low light density will be available at the corners of the coverage area. For example, for 2000W grow light, only 109 μ mol/sec.m2 light density is available at a distance of 4 ft.
Heat & Cooling
The device has an advanced cooling system with 2-4 fans in different models of the grow lights. The smaller models i.e. 1000 W & 1500 W have 2 fans while the larger models i.e. 2000W & 3000W, have 4 fans. There are sinkholes at the rear and sides of the panel. There are 4 holes in the front glass of the panel as well for the dissipation of heat. The cooling system maintains the inner temperature of the device and keeps it operating at an optimum temperature for a long period.
Some of the significant secondary features of the device are as follows:
- The device can be controlled by a timer.
- LEDs are oriented at 120o for wider coverage.
- There is no need for extra ballast.
- The grow lights have a long lifespan of 50,000 – 100,000 hours.
- 10 kinds of LEDs are used to produce the spectrum.
- 3 years warranty with 30 days nonsatisfaction or return guarantee.
