We took everything out and put it on the table so that it looked nice and carefully.
Below are the various sides of the main light, I took a picture for everyone to see.
Below are photos of spare parts, including anti-glare sunglasses, ratcheting pulleys that can be raised and lowered, metal slings, and power cords.
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 center line parallel to the long side of the rectangle is the X-axis, and the center line parallel to the short side of the rectangle is the Y-axis.
We take two measurements, and we put them on the Z axis, 24 inches above the light, and we measure them.
Here is the spectrum that we measured with this instrument, and we took it out of the instrument, and you can see that the spectrum is pretty good.
Here is the spectrogram of the plants growing light under the brand Fluence, which is very well known in the plants growing light industry. You can refer to it.
As you could see the spectrum of this lamp and fluence are very close, and this lamp has three kinds of light to choose from, which can meet the different needs of the seedling, growing and flowering stages of plants. Of course, this lamp is not very powerful. In some large-scale planting scenes, we'd better add a low-power HPS high-pressure sodium lamp or CMH metal halide lamp to make up for it.
3.1. Let's first measure the spatial distribution of the light quantum flux density of this lamp
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 relatively tedious, the position and height are constantly changed. 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.
Let's take the data from the above three measurements, and from the side view, we can make the following conical light distribution map.
A simple calculation method for the area covered by a plants planting lamp is to hang the lamp to a certain height to ensure the central photosynthetic effective light quantum flux density (PPFD) value is 200 μmol / m ^ 2 / s, and then find the effective photosynthetic efficiency The light quantum flux density (PPFD) value is 150 μmol / m ^ 2 / s, the distance from the boundary to the center point. Within this radius, it can meet the lighting requirements of the plants seedling stage. The other is to hang the lamp to a certain height to ensure the photosynthetic effective light quantum flux density (PPFD) value of the center point is 800 μmol / m ^ 2 / s, and find the photosynthetic effective light quantum flux density (PPFD) value of 600 μmol / m ^ 2 s The distance from the boundary to the center point, within this radius, can meet the lighting requirements of the plants growing period and flowering period.
Let's look at the effective exposure data of this light in this way.
3.2. How much area can this plants planting lamp cover if used for plants seedlings?
The appropriate illumination intensity of plants seedlings was 200±50 mol/m^2/s. We chose a small pot with a square mouth and the size of the pot mouth was 3.93 inches (10 cm).On the other hand, ECO FARM 480W LED grow lights can cover an area of 24.58 square feet (2.28 square meters), or 182 plants.
According to the measurement data, using the ECO Farm 480W LED indoor planting light in the seeding area, the height of the plants seedling top from the light is about 38 inches (96.52 cm), at this time, the maximum coverage radius is measured to be 15 inches. As shown in the figure below.
If the ECO Farm 480W LED lights are used in a large area of plant nursery, a light can cover an area of 5.00 feet times 4.92 feet is equal to 24.58 square feet.Because of the large area, the lights will stack up, and the edges will reach PPFD: 150 mol/m^2 s. As shown in the figure below.
3.3. How much area can this led light cover for the growing and blooming period of plants?
The suitable light intensity of plants seedlings is 200 ± 50 μmol / m ^ 2 / s. We use small flower pots with square mouths for common plantsseedlings. The mouth size of the pots is 3.93 inches (10 cm). In the nursery area, the ECO FARM 480W LED GROW LIGHT DXG plantsplanting lamp can cover an area of 24.58 square feet (2.28 square meters), which can cover 182 plants seedlings.
According to the measurement datas, using ECO Farm 480W LED light in the growing area, the height of the plants seedling top from the light is about38.00 inches (96.52 cm). At this time, the maximum coverage radius is 15.00 inches. As shown below.
For large growing areas where plants is growing and flowering, the LED lights require one light for every 6.22 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/m^2 s. As shown in the figure below.
From the above data, it can be seen that this kind of light has strong light gathering ability, so its effective coverage area is relatively small. If the planting area is large, a lot of lights need to be arranged closely.
I suggest you can match HPS or CMH to do a mixed light scheme, so that can be a good solution to this problem. 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 take a look at the light beads, which are made by the 3030 Chips.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.
Finally, let's take a look at the heat dissipation of this lamp. The lamp itself has a small fan inside. When the lamp starts running, the fan is turned on, which can effectively dissipate heat.
In addition, the shell of the LED lamp of this lamp is an aluminum substrate, the aluminum substrate is very thick, and the heat capacity is relatively large. The surface area of the heat-dissipating aluminum profile is also large enough to quickly dissipate the heat of the lamp beads.
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.
Finally, we will be the light for a period of time, to see the actual power consumption, we use an electric power testing instrument to actually look at this light is really save electricity, first of all, we look at its instantaneous power, the display is 419.1 w with instructions for the 7480 w is similar, instantaneous power near the average power fluctuation is a normal phenomenon.
From the picture, we can see that we lighted this lamp for 233 minutes in total. The actual power consumption is only 1.60kwh, and 24 hours is 1440 minutes. In this way, the power consumption for 24 hours a day is about 1.60 * 1440/233 = 9.89kwh.
At $0.125 a kilowatt-hour, you could cover 24.58 square feet of plants growing space for $1.236 a day.1 square foot (sq.ft)=0.092903 square meters (sq.m), which is the area that can cover 2.28 square meters.
If you cover growing and flowering areas, you can cover 6.22 square feet.1 square foot (sq.ft)=0.092903 SQM (SQM), which is the area that can cover 0.58 SQM.
If your room is 5 meters wide and 6 meters long and 30 square meters (323sq.ft), remove the non-growing area in the space, and the growing area is about 20 square meters, then 28 of these lights will be enough. The lighting time for plants growth is usually only 16 hours per day, so the real daily electricity cost should be 23.19USD.
(1) the spectrum is very good, very close to the spectrum of the authoritative plants cultivation light of Fluence brand.
(2) the illumination area is relatively large. In the 480-watt planting light, 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 480-watt grow light on the market.
(5) The spectrum of this lamp can be adjusted to a certain extent, so that the most suitable spectrum can be selected at different growth periods.
