ECO FARM GA 96 X 3 LED GROW LIGHT EVALUATION

January 21, 2020

1. We are now unpacking ECO FARM GA 96 X 3 LED GROW LIGHT

Let's take everything out and put it on the table so we can be more careful.

Here are the different sides of the light, and I'll show you.

The following is the photo of the spare parts, including ratchet pulley, metal rope, and power cord

2. First, measure the spectrum of ECO FARM GA 96 X 3 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 lamp 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 lamp 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.

We measured two meters, 24 inches above the light, on the Z-axis.

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 cannabis grow light under the brand Fluence, which is very well known in the cannabis grow light industry.

We can see that this light is the most important red light band is very good to meet our planting requirements, but although the red light segment is good, but some other band is not satisfactory, we had better add a low power HPS high-pressure sodium lamp, or CMH metal halide lamp to make up for it.

3. Let's test the coverage area of this light when planting marijuana

3.1. 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.

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 marijuana grow lights, how much can cover area of the simple calculation method is, to turn the light on a certain height to ensure that the center of photosynthetic photon flux density effectively (PPFD) value is 200 mu mol/m ^ 2 / s, and then find the photosynthetic photon flux density (PPFD) effective value is 150 mu mol/m ^ 2 / s boundary distance of center distance, in the radius scope, can meet the demand of marijuana in seedling stage lighting.

Let's look at the effective exposure data of this light in this way

3.2. How much area can this cannabis grow light cover if it is used for hemp seedling cultivation?

The appropriate illumination intensity of cannabis 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). ECO FARM GA 96 X 3 LED GROW LIGHT can cover an area of 12.40 square feet (1.15 square meters), or 99 plants.

According to the measurement data, when ECO FARM GA 96 X 3 LED GROW LIGHT was used in the nursery area, the height of the top of the cannabis seedling was approximately 36.50 inches (92.71 cm) from the light, and the maximum coverage radius was measured to be 13.50 inches. As shown in the figure below.

If the ECO FARM GA 96 X 3 LED GROW LIGHT is used on a large scale in a nursery area, a lamp can cover 3.92 feet times 3.17 feet equals 12.40 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.

According to the above data, the intensity of this light is not high, and the light gathering ability is relatively strong, that is, the illumination range is relatively small, and the coverage area is too small during the growing and flowering period, so if you are planting a large area, you need to arrange a lot of this light densely. Therefore, I choose to use it to grow seedlings.

So I suggest this light had better be used at the seedling stage if want to be used at the growing area and flowering period especially when the flowering period, had better cooperate with a kind of HPS high-pressure sodium lamp or CMH gold halide lamp, can overcome this defect so.

4. Let's have a look at the quality of this light

I finally took this light apart to see the inside situation, let's first look at the situation of the light bead, from the details of the light bead, this light bead is the Korean brand SAMSUNG. This kind of bead is the main application in the grow 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 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.

5. Let's take another measurement to see if this light saves electricity.

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 126.6 w with instructions for the 130 w is similar, instantaneous power near the average power fluctuation is a normal phenomenon.

It can be seen from the picture that we have lit the light for a total of 350 minutes, and the actual electricity consumption is only 0.71 KWH, while that of 24 hours is 1440 minutes. In this way, the 24-hour electricity consumption of a day is about 0.71*1440/350=2.92kwh.

At $0.125 a kilowatt-hour in the U.S., you can cover 12.40 square feet of marijuana growing space for just $0.365 a day.1 square foot (sq.ft)=0.092903 square meters (sq.m), which is the area that can cover 1.15 square meters.

If your seedling area is an area of 10 square meters (107.6sq.ft) with a width of 2 meters and a length of 5 meters, 9 of these lamps will be enough. The lighting time for seedling breeding is usually only 16 hours per day.

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

Finally, I will give you a summary of the actual measurement of this light, which has the following five advantages:

(1) the spectrum is very good, very close to the spectrum of the authoritative cannabis cultivation lamp of Fluence brand. 

(2) the illumination area is relatively large, which can be regarded as a relatively large area in the 130-watt cannabis grow light.

(3) the quality is really excellent, the main core components are the brand products produced by big factories, the application of two or three years should not be bad.

 (4) the price is really cheap. You can hardly find a cheaper 130-watt cannabis grow 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 lamp power is small, the growth and flowering again big, just a light can meet the growing marijuana, and also can choose the appropriate power and not waste electricity, it is for small farmers tailor-made products.

At this point, we have completed the evaluation of this light.

Finally, I am very happy to share all kinds of interesting things about marijuana with you. Please also help me post this assessment thumb up, forward it and comment on it so that more people can see it and we can have more influence.
