ECO Farm 1000W Double Ended HPS Controller Compatible Grow Light Kit Evaluation

January 15, 2020

1. Now we unpack the 1000W Double Ended HPS Controller Compatible Grow Light Kit

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, metal sling, power cord and so on

There is also a switch for electrical plugs in different countries, which is commendably adaptable to all plugs

2. Let’s measure the spectrum of the ECO Farm 1000W Double Ended HPS Controller Compatible Grow Light Kit  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 this light provides plenty of green and red light band, can well meet the requirements of our plant, but the from 400 to 550 the band is a bit poor, you may know that HPS is not the same as the LED, its spectrum is not can adjust, so the HPS lamp is spectrum, this also is the defect of HPS lamp, we at the time of planting, according to the different stages of growth, it is best to add a can provide blue leds to make up for it.

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

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 24 inches, 30 inches and 36 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 light 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 light cover if used for plants seedlings?

 The appropriate light intensity for adult plants  was: 800±200 mol/m^2/s, and we chose the commonly used medium pot with a square mouth during the growing period and a mouth size of 11 inches (27.94 cm). ECO FARM 1000W DOUBLE ENDED HPS CONTROLLER COMPATIBLE GROW LIGHT KIT can cover an area of 23.61 square feet (2.19 square meters), or 24 plants.

  According to the measurement data, when the ECO FARM 1000W DOUBLE ENDED HPS CONTROLLER COMPATIBLE GROW LIGHT KIT was used in the growing area, the height from the top of the plants seedling to the LIGHT was about 33.00 inches (83.82 cm), and the maximum coverage radius was 34.00 inches.As shown in the figure below.

   For large growing areas where plants is growing and flowering, the LED lights require one light for every 23.61 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 the intensity of this lamp is relatively high, but the spectrum is relatively concentrated. Therefore, I suggest that when HPS is used as the main growth lamp, it is better to use it together with a blue LED lamp at the seedling and growth stages, so as to make up for this defect.

   4. Let's check the quality of this light  

  Let's take a look at the light bulb, which has a cylindrical glass inside it, and this is the HPS light bulb, and just to give you a little bit of an idea, with current technology, the light efficiency of HPS is usually 140lm/W, and the quantum flux efficiency of converted photosynthetic light is about 2.3umol/s/W.

  Finally, let's take a look at the heat dissipation of this lamp. The luminous tube of this lamp and the power supply are provided with a reflective cover and two heat insulation covers. The distance is also relatively large. 


  Judge from all of the details, 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 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 lamp is really save electricity, first we look at its instantaneous power, display is 1191.2 w, although this lamp in ECO Farm is sold according to 1000 w, but the actual hand me the lamp power can be output 1200 w power, that is mean you actually buy on a 1000 w to 1200 w HPS grow lights.


   From the picture, we can see that we lighted this lamp for 885 minutes in total. The actual power consumption is only 17.26 kwh, and 24 hours is 1440 minutes. In this way, the power consumption for 24 hours a day is about 17.26 * 1440/885 = 28.08kwh.  

  At $0.125 a kilowatt-hour, you could cover 23.61 square feet of plants growing space for $3.511 a day.1 square foot (sq.ft)=0.092903 square meters (sq.m), which is the area that can cover 2.19 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 15 square meters, then 7 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 16.00 USD.

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

(1) the spectrum is very good, and the HPS lamp is also very suitable for growing plants. 

(2) the illumination area is relatively large, which can be regarded as a relatively large area in the 1,200-watt  planting lamp. 

(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 1000w plantation lamp on the market, and in fact the maximum power output is still 1200w. 

(5) it is can adjust the brightness of the lamp, 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 plants , and also can choose the appropriate power and not waste electricity, it is for small farmers tailor-made products. 

  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.
