ECO Farm 360W ZB-X6 COB Full Spectrum LED Grow Light Evaluation

January 14, 2020

1. Now we unpack the ECO FARM 360W COB LED GROW LIGHT

Below are the various sides of the main light, I took a picture for everyone to see.



2. Let’s measure the spectrum of the ECO FARM 360W ZB-X6 COB LED grow light first

  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 that this laight can feed our planting requirements in the most important blue and red light bands, but it is a little unsatisfactory in the band of 500 to 600. We better add a low power when planting HPS high pressure sodium lamp, or CMH metal halide lamp to make up for it.

3. Let's measure the coverage area of this lamp.

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 how much area a plants  planting lamp can cover is to find the distance from the center point of the boundary of the photosynthetic effective light quantum flux density (PPFD) value of 150 μmol / m2s. Within this radius, the plants seedling stage can be satisfied Lighting requirements.
The other is to find the distance from the center point of the boundary of the photosynthetically effective photosynthetic quantum flux density (PPFD) value of 600 μmol / m2s. Within this radius, it can meet the lighting requirements of the plants growing period and the flowering period.

3.2. How much area can this plants  planting lamp cover if used for plants  seedlings?

 The suitable light intensity of plants seedlings is 200 ± 50 μmol / m ^ 2 / s. We use small flower pots with square mouths for common plants seedlings. The mouth size of the pots is 3.93 inches (10 cm). In the nursery area, the ECO FARM 360W LED GROW ZB-X6 plants planting lamp can cover an area of 28.41 square feet, which can cover 256 plants seedlings.

  According to the measurement datas, using ECO Farm 360W ZB-X6 LED light in the growing area, the height of the plants seedling top from the light is about 51.00 inches (129.54 cm). At this time, the maximum coverage radius is 32.00 inches. As shown below.

  If the ECO Farm 360W ZB-X6 is used in a large area in a nursery area, a lamp can cover an area of 5.33 feet by 5.33 feet equal to 28.41 square feet. Because of the large area, the light will be superimposed, so that the edge will reach PPFD: 150μmol / m2s. As shown below.

3.3. How much area can this led light cover for the growing and blooming period of plants?     

  We use medium-sized pots with square mouths that are commonly used for plants growth. The size of the mouth is 11 inches (27.94 cm). In the growing season, ECO Farm 360W ZB-X6 can cover 4 square feet, which is 4 plants plants. The suitable light intensity for adult plants is 800 ± 200μmol / m2s. ECO Farm 360W ZB-X6 was used in the growing area. The height of the top of the plants leaf was about 26 inches (66.04 cm) from the lamp. As shown below.

   For large growing areas where plants is growing and flowering, the LED lights require one light for every 4 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, the intensity of this lamp is not particularly high, and the coverage area is not particularly large, so if you are planting in a large area, you need to arrange a lot of this lamp.

  So I suggest that when planting in a large area, it is best to cooperate with an HPS high pressure sodium lamp or CMH gold halogen lamp, so that this defect can be compensated.

4. Let's check the quality of this light

  Finally i took this light apart and looked at the situation inside. Let's first look at the situation of the lamp beads. From the details of the lamp beads, this lamp bead is a German OSRAM brand lamp bead. This lamp bead is the mainstream lamp bead currently used in the plant lamp industry. This lamp bead has high photosynthetic quantum number efficiency and is a relatively energy-saving lamp bead.

  Let's take a look at the heat dissipation of this light. This type of heat dissipation is aluminum alloy profile. The aluminum substrate is very thick and the heat capacity is relatively large. The surface area design of the heat dissipation aluminum profile is also large enough, and the ventilation design between the aluminum grids of the profile is also Excellent, can 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. 

5. Saving electricity bill

  Finally, we will lighting item 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 358.6 w with instructions for the 360 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 644 minutes in total. The actual power consumption is only 3.82 kwh, and 24 hours is 1440 minutes. In this way, the power consumption for 24 hours a day is about 3.82* 1440/233 = 8.59kwh.

  At $0.125 a kilowatt-hour, you could cover 32.1 square feet of plants growing space for $1.07 a day.1 square foot (sq.ft)=0.092903 square meters (sq.m), which is the area that can cover 2.98 square meters.   

If you cover growing and flowering areas, you can cover 4 square feet.1 square foot (sq.ft)=0.092903 SQM (SQM), which is the area that can cover 0.37 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 42 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 30.07USD

6. The following is my evaluation of the advantages of this planting light after the actual measurement

(1) The light intensity is sufficient.
(2) The quality is really excellent. The main core components are brand products produced by major manufacturers. It should not be broken after three years of application.

At this point, we have completely evaluated this lamp. If you are interested in this lamp or other products, you can contact Mary, product sales director of ECO FARM GREEN INC.
