When purchasing your LED grow light the choice of products and suppliers can seem very confusing. The truth about LED grow lights. When choosing a suitable LED grow light customers often find that there is a lot of conflicting information with regards to different wattage's , colour spectrums, different sized LED's and seemingly overly optimistic estimations of the equivalent output CFL / HPS / HID lighting solutions.
The choice can be simplified a great deal with just a small amount of knowledge which is outlined below. What type of lights do plants need to grow? This question is really the most important issue to bear in mind when comparing different types of grow lights. Traditionally light bulbs have been measured in terms of Lumens. When thinking about the lighting needed to grow plants one needs to gain an understanding of what types of light plants respond to.Traditionally the solution has just been to use the most powerful HPS / HID lights which although effective only have a small percentage (15-30%) of their actual output in the correct spectrum for plant growth. One of the key advantages to LED lighting is that the wavelength of the LED can be specifically manufactured to coincide with the wavelengths that plants require to grow.
This means as well as being more efficient at converting electricity to light in absolute terms LED's used for growing can also be refined only to produce the spectrum of light which the plant will use to grow. This means that watt for watt LED can be 15 times more efficient than HPS / HID lighting at producing growing light for plants. This means less heat, and less electricity costs.
Below is a chart of the plant growth plotted against light wavelengths. From this chart it is possible to see which wavelengths of light will produce growth in plants and then it allows us to make up a specification of LED light which outputs only the light at the wavelengths which are useful for plant growth for the maximum growth potential. Below is a break down of the different wavelengths of light and the effect each one has on plant growth. The Peak growing wavelengths for plant growth occur at 425nm and 460nm and again at 640nm and 670nm. To get maximum plant growth it is ideal to target any lighting specifically around these frequencies.Any lighting out side of plant growth frequencies can actually be damaging to the plants as described in the data below. The wavelengths of light are on the bottom scale and the plant growth repsose is charted in the vertical axis (higher numbers on vertical axis = better growth as measured by chlorophyll production). How the Sunlight Effects Plant Growth.
UVC ultraviolet range which is extremely harmful to plants because it is highly toxic. Includes harmful UVB ultraviolet light which causes plants colors to fade.
Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth. Start of visible light spectrum. Process of chlorophyll absorption begins.
UV protected plastics ideally block out any light below this range. This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. This range includes the green, yellow, and orange bands and has less absorption by pigments.
This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.
All energy absorbed at this point is converted to heat. The above information can be simplified into a measurement called PAR (photosynthetically active radiation) This measurement is similar to Lumens, however whereas lumens measure visible light output PAR measures light output of wavelengths which are applicable to plant growth. Very simply the higher the PAR reading the better the light for plant growth, regardless of wattage and regardless of Lumen output. When considering plant growth PAR is the most important measurement to consider.Coming soon we will be publishing our test results from all of our LED and CFL grow lights and also publishing the results from market leading HPS / HID lighting solutions to ensure that the customer has all of the information needed to make an informed decision when purchasing lighting for plant growth. Our powerful 240w LED grow light will replace a standard 600W to 700W HPS/HID grow lights, saving you 7 0% on electriciy. Benefits of Green Lamp LED boards. 20% more PAR than 1W boards.
Larger heatsin ks and fans for cooler running temperatures. The 240W LED panel utilizes highly efficient, wide angle 3 watt LEDs, using only the exact spectrums required for plant photosynthesis. The light spectrum is tailored to the absorption spectrum of chlorophyll, caroten, phycoerythrin and phycocyanin. It's ideal for all phases of plant growth, and works well with any indoor garden, whether hydroponics or soil based.The directional nature of the LEDs ensures 100% of the light is pointed downwards so no reflective material is needed. The low heat emission also eliminates the need for ducting and heat exhaust fans. Built-in thermo-sensitive devices cut off power supply if over-heating happens, either due to high ambient temperature or ventilation problems.
3 top quality heavy duty fans are used to cool the unit. This Grow Baord is built to the highest standards - top quality.It is not a light weight flimsy construction - it is very solidly built and. + Help to save the Planet. With daily use, this Green Lamp Grow Panel will save. Of CO2 per year compared to the Halogen equivalent. Next Day UK Mainland = FREE. FREE POST ON ANY ADDITIONAL PANELS.
