ECO Farm 240W Quantum Board LED Grow Light With LM561C / LM301B Samsung Chip Evaluation
We are now opening the ECO FARM QUANTUM BOARD LED GROW LIGHT.
They sealed all the gaps with tape, but the tape was pasted neatly, which did not affect the appearance. Now we open the package with paper cutting knife to see what was going on inside. As you can see, inside the large carton, all around, including the top and bottom, are filled with airbags, this kind of shock protection is too much.
Let's take this light out and put it on the table for you to see. Look from the outer packing, concise and clear. The best part is that the color picture of this product is pasted on the side so that you can know the product inside without opening the box. This is a thoughtful design.
We then open the individual product packaging box, the first thing you see is a white, thick enough soft foam foam foam layer, and is filled on both sides and all sides, this protection is too abnormal.I'll show you the pictures.
As we continue to open it, we can see the well-placed lights and their accessories. The place where the product is placed and the place where the part is placed are separated by a small protective layer to prevent metal or other aluminum products in the part from getting into the light and causing damage to the light, and the main part is also sealed with anti-static bags to prevent light beads from being damaged.
Let's take everything out and put it on the table so we can be more careful. As you can see, the parts are metal hangers, copper columns, connectors, Dimmer, power supplies, and power cords.
Let's take a look at the manual first. The manual is very thick and there are seven languages. I will take two pages of the manual in English and show them to you.
Of course, the light certification is also complete. CE and RoHS are available, and the quality is guaranteed.
Here are the lights and some accessories, I'll take a picture to show you.
The light has a total of 576 beads, including two-color ranges. Among them, 504 beads emit warm white light with a color temperature of 3200K.72 beads emit red light, and the wavelength of red light wave is 660nm.
First measure the spectrum of ECO FARM QUANTUM BOARD LED GROW LIGHT.
Now I hang up this light, put it straight and flat, and set up a coordinate system for spatial measurement of this light according to my previous practice of doing evaluation. As shown in the figure below: from the bottom of this light, which is the center point of the light bead face, vertically downward, is the z-axis. From the center of the bead face, the centerline parallel to the long side of the rectangle is the X-axis, and the centerline parallel to the short side of the rectangle is the Y-axis.
Let me show you our measuring instruments again. We take these two meters, and we put them on the Z-axis, 24 inches above the light, and we measure them.
Here is the spectrogram that we measured with this instrument, and I took the data out of the instrument, and you can see clearly that the spectrum of this light is pretty good.
Here is the spectrogram of the plants growing light under the brand Fluence, which is very well known in the plants grow light industry.
Here is the spectrogram of the plants grow light under the brand Fluence, which is very well known in the plants grow light industry.
Again, let's measure the area of the light when growing plants
1. Let's first measure the spatial distribution of the light quantum flux density of this light
We placed the measuring mesh cloth with the dimensions I had drawn before directly under the light, and then measured the quantum flux density of light at each point on the mesh cloth by setting the distance between the light bead and the mesh cloth as 12 inches, 18 inches, and 24 inches respectively.
The whole process is quite complicated, that is, constantly changing the position and height. I have sorted out the specific measurement values for you and marked them directly on the measuring grid. As shown in the following three pictures.
The photon flux density of ECO FARM QUANTUM BOARD LED GROW LIGHT (experimental measurement diagram)
Let's take the data from the above three measurements, and from the side view, we can make the following conical light distribution map.
The simple calculation method of how much area a plants planting light can cover is to find the distance between the boundary and the center point of the photosynthetically available light quantum flux density (PPFD) value of 150, within this radius, it can meet the lighting demand of seedling period.
The other is to find the distance between the boundary and the central point with the value of the photosynthetically available light quantum flux density (PPFD) of 600, which can meet the illumination requirements of the growing period and flowering period of plants within this radius.
2. How much area can this growing light cover if it is used to grow plants seedlings?
We used the usual small pot with a square opening, with a size of 3.93 inches (10 cm). ECO FARM QUANTUM BOARD LED GROW LIGHT can cover an area of 14.3 square feet or 108 plants. The appropriate light intensity of plants seedlings was 200±50
Using ECO FARM QUANTUM BOARD LED GROW LIGHT in the nursery, the top of the seedling was about 36 inches (91.44 cm) from the light, and the maximum coverage radius was 24 inches, according to the measurements. As shown in the figure below.
If you use the ECO FARM QUANTUM BOARD LED GROW LIGHT on a large scale in a nursery area, a light can cover 3.3 feet times 4.25 feet is equal to 14.3 square feet. Because of the large area, the light will be superimposed, so that the edge will also reach PPFD. As shown in the figure below.
3. How much of the growing and flowering plants can be covered by this plants planting light?
We used a medium-size pot with a square cut in the growing season. The pot size was 11 inches (27.94 cm). ECO FARM QUANTUM BOARD LED GROW LIGHT can cover six square feet, or nine plants, during the growing season. The appropriate light intensity for adult plants was 800±200 mol/m2s. Using ECO FARM QUANTUM BOARD LED GROW LIGHT in the growing area, the top of the plants leaf is about 18 inches (45.72 cm) from the light. As shown in the figure below.
For large areas where plants is growing and flowering, the LED lights require one light for every 9 square feet. Because a large area is uniformly arranged with multiple lights, the lights will be superimposed, so that the edges will also reach PPFD: 600 mol/m2·s. As shown in the figure below.
From the above data, the intensity of this light is not particularly high, the coverage area is not particularly large, so if you are a large area of planting, you need to arrange a lot of this light. So I suggest, when large area planting, the best with an HPS high-pressure sodium light or CMH gold halide light so can make up for this defect. As for how to prepare and arrange such a hybrid light source, you can contact Mary, director of product sales at ECO FARM GREEN INC., whose engineers will help you design a hybrid light source solution for plants cultivation for free.
Let's see the quality of this light
Let's take a look at the light bead first. From the details of the light bead, we can see that this light bead is a light bead of the SAMSUNG brand from South Korea. This kind of light bead is the main application in the plant light industry at present. It has a high photosynthetic quantum number efficiency and is a light bead that saves electricity.
Let me show you the power supply again. This is the power supply of the Ming Wei brand in Taiwan. This brand is the most famous power source in the global power industry.
Finally, let's take a look at the heat dissipation of this light. The aluminum substrate of this light is directly connected to the large aluminum alloy heat dissipation plate behind it. The aluminum substrate is very thick, with large heat capacity.
Judge from a few details above, this light, true quality is good. Mary, director of product sales at ECO FARM GREEN INC., told me they offer a three-year warranty on the light, with free warranty and replacement service for three years. I think the quality of this light will not be any problem after three years.
Let's take another measurement to see if this light saves electricity.
Finally, we use an electric power testing instrument to actually check whether this light is really power-saving. First, we see its instantaneous power, which shows 238.3w, which is similar to the 240w given in the manual. It is normal for the instantaneous power to fluctuate near the average power.
Now let's turn this light on for 7 hours to test the actual power consumption.
As can be seen from the picture, we have lit this light for 419 minutes in total, and the actual electricity consumption is only 1.54kwh, while that for 24 hours is 1440 minutes. In this way, the electricity consumption for 24 hours in a day is about 1.54*1440/419=5.29kwh. At $0.125 a kilowatt-hour, you could cover 12 square feet of plants nursery space for just $0.66 a day.1 square foot (sq.ft)=0.092903 square meters (sq.m), which means it can cover 1.1 square meters. If you cover growing and flowering areas, you can cover 8.2 square feet.1 square foot (sq.ft)=0.092903 SQM (SQM), which is the area that can cover 0.77 SQM. If your room is 5 meters wide and 30 square meters long, remove the non-growing area in the space, and the growing area is about 20 square meters, then 26 such lights will be enough. The lighting time for plants growth is usually only 16 hours per day, so the real daily electricity fee should be 11.47USDPersonally, I think this light is especially suitable for small tent planting. One light is enough for one tent. Mary, director of product sales at ECO FARM GREEN INC., told me that the lights are used in one of their small tent sets. You can go to their official website ecofarm.ca to buy, will be cheaper.
The following is my evaluation of the advantages and disadvantages of this plants planting light after the actual test.
Finally, I will give you a summary of the actual measurement of this light, this light has the following five advantages:
(1) the spectrum is very good, very close to the spectrum of the authoritative plants cultivation light of the Fluence brand.
(2) the illumination area is relatively large. In the 240-watt planting lamp, it can be regarded as illuminating a relatively large area.
(3) the quality is really excellent, the main core components are the brand products produced by big factories, the application of three years should not be bad.
(4) the price is really cheap. You can hardly find a cheaper 240-watt plants light on the market.
(5) it is can adjust the brightness of the light, so it is very good for small farmers, the pot seedling stage can turn the light power is small, the growth and flowering again big, just a light can meet the growing plants , and also can choose the appropriate power and not waste electricity, it is for small farmers tailor-made products.
The disadvantages of this light are as follows:
(1) this light is only coated with waterproof paint, and it is directly exposed to the air, so it is basically not waterproof. If you use spray irrigation, you can't use this light.
(2) the intensity of this light is not particularly high, if you are a large area of planting, it is better to cooperate with an HPS high-pressure sodium lamp or CMH gold halide lamp, so as to make up for this defect.
At this point, we have completed the evaluation of this light. If you are interested in this light or other products, you can contact Mary, product sales director of ECO FARM GREEN INC., LTD.
