What makes the best grow light?
To help you choose from the wide variety of shapes, sizes, wattages, prices, and more. that can be found on the Internet, let’s see what are the really important criteria to take into account before buying.
- The price will depend mainly on the quality of manufacture, but also on certain options which can bring a real advantage to the use.
- For the panels, some models offer fans associated with aluminum heatsinks or the possibility of chaining several panels in the same installation.
- For lamps, the options that can influence the price are the number of heads, switches, and the ability to vary the lighting intensity.
- For bulbs, it is mainly the quality of the heatsinks that can make the difference.
- Be careful to adapt the power of your installation to your needs. Indeed, it will be very different for a small bonsai or a palm tree over a meter high.
- An important selection criterion is also the warranty period for the equipment. The longer it is, the more confidence the manufacturer has in the origin of the parts and their manufacturing and testing process.
#1. The light flux supplied by LED
You should know that not all plants have identical needs and tolerance levels in terms of light flux.
This is because each species has a maximum value of light that it can absorb before taking damage. Unfortunately, this value is difficult to know and it will be necessary to base yourselves on studies and research carried out according to the different types of plants on this subject.
To have an estimate of the exposure required for each plant, you can go to the Conservation Nature site and in particular to their plant encyclopedia to find out about the different needs of plants (sun / partial shade/shade).
#2. The light spectrum emitted by the lamp
The concept of the light spectrum is very important in the choice of horticultural LEDs. These are the set of wavelengths that are emitted by a source of light, be it the sun or artificial light. The part of the light spectrum visible to our eye extends from 400 nm to 700 nm. Below 400 nm, we speak of ultra-violet and beyond 700 nm, it is infrared.
When all the wavelengths are united in the same luminous flux, the light appears white to us, but if we separate them they are then perceived by our eye as distinct colors. This is what happens when sunlight is diffracted by water drops and we see it as a rainbow.
#3. Power supply
The peculiarity of LEDs is that they cannot work directly on the household electrical network at 230 volts.
In the case of horticultural LED panels, it is preferable to take a model with the remote power supply, rather than integrated, to prevent the heat generated by it from accumulating with that of the LEDs.
#4. The cooling system
The heat is extremely important in the field of lighting it with horticultural vocation or not.
Even though LEDs produce less heat than other technologies, this heat is not negligible and must be taken into account. For panels of a certain power, it is imperative to dissipate the heat to guarantee the life of the lamps, but also in the case which interests us, to avoid temperature increases detrimental to the plants.
There are two cooling techniques: active dissipation and passive dissipation.
- Active dissipation
The active dissipation is based on fans that extract hot air around the lamps so that it is replaced by cooler air. This principle is simple and proven because it is used in many everyday devices.
- Passive dissipation
The passive dissipation as the name suggests is not based on any moving part, but on the presence of a piece of metal put in direct contact with the heat source (that is to say, the lamps). Metal has the physical property of dissipating heat in the surrounding air, thereby cooling lamps.
#5. Noise problems
In addition, a poor quality lighting device can in some cases produce annoying hissing or noise.
In conclusion, it can be said that the lower the quality of the lighting device, its components, and its manufacture, the higher the risk of noise pollution.
#6. Sealing of the lighting system
Certain types of plants require fairly high humidity and temperature (carnivorous plants for example). It is therefore strongly recommended to choose lighting equipment that can function and above all withstand these conditions of use.

How can you rate the quality of Led grow light?
#1. The Efficiency
The lighting of LED grow light needs to be equivalent to the lighting emitted by the Sun. These light sources not only allow plants to grow through photosynthesis but also activate fruiting or flowering thanks to the time of light, Photosynthesis. Without light, plants will quickly weaken (yellow leaves) and die. This process converts atmospheric carbon dioxide and water into carbohydrates (sugars). Chlorophyll is a pigment that absorbs the red and blue components of light and gives leaves their green color.
Light is essential to the success of your hydroponic system or soil.
#2. The Intensity
To enhance the intensity of horticultural lighting, reflectors are perfect. Some bulbs will need ballast like HPS and MH bulbs.
Maybe you want to get straight to the point, in this case, Culture Indoor offers you pre-designed interior luminaires to adapt to any surface. Find kits CFL or kits HPS / MH our
How Should We Measure LED Grow Light? Light intensity or intensity can be measured by the total wattage of LED grow lights. The higher the power, the brighter the light. Another measure is lighting the plants with lamps. Another measure is the photosynthetic active radiation (PAR) of plant growth lamps, which measures the efficiency of plant growth lamps by plant photosynthesis.
The PAR value was measured as the photosynthetic photon flux density (PPFD) µmol / m2 / s in micromoles per square meter per second. PPFD measures the amount of PAR light (photons) reaching the surface of the plant per second. The effective PAR must be above 500 μmol / m2 / s to be effective for plant photosynthesis.
G8LED grow lamps have a high PAR of 600-1700 μmol / m2 / s, which means they are very efficient in growing plants. G8LED lamps maximize the energy consumed by the light to provide maximum power output. Grow healthier, intensely flowering plants with more trichomes. G8LED lamps allow you to grow plants with great taste, aroma, and power.
#3. The Range
Your choice of LED garden lights will depend on the surface you want to illuminate. The light coverage of LEDs is determined by their lens angle which varies from 20° to 160°. The larger this angle, the larger the coverage area of the lamp. On the other hand, the photon flux and hence the illumination intensity will decrease accordingly, as it is distributed over a larger area.
Wide lens lights can be very useful for seedlings or young shoots, as they can be placed closer to them and at the same time provide a little extra heat to them.
It is usually advisable to illuminate an area larger than that covered by vegetation to avoid losses to the sides, but this then leads to unnecessary heat consumption and production. So, if possible, calculate the exact size of your area and choose the lights that best suit your needs.
#4. The ratio of different wavelengths/colors of light
The concept of the light spectrum is very important in the selection of LED garden lights. This is the set of wavelengths are emitted by a light source, be it the sun or artificial light. The part of the light spectrum that our eyes can see ranges from 400 nm to 700 nm. Below 400 nm, we mean ultraviolet, and beyond 700 nm, it is infrared.
- During the development stage of our flora maximum use of light “blue”, a wavelength from 400 nm spectrum to 500 nm.
By providing enough green light to plants during this time, you may find that they have more leaves, stronger roots, and shorter internodes than unexposed specimens. This is because the plant does not need to stretch these stems to get as much light as possible.
- During the blooming stage, they mainly use red light. The wavelengths of the spectrum are from 620 nm to 780 nm.
To make these different colors, there are usually 4 types of LED grow lights on the market:
- LED grow lights (mostly blue)
- Flowered LEDs (mostly red)
- Mixed LEDs (with predefined blue and red distribution)
- Customizable LEDs (allows you to choose colors)
In fact, the majority of commercial horticultural LED panels or lights contain a mixture of colors with a ratio of about 80% red and 20% blue. This is the best compromise because it will fit all situations while avoiding unduly high costs.
It is possible to choose lamps that diffuse the entire light spectrum, thus ensuring that plants always have the wavelengths they need at the right time. Partner of this choice will be higher consumption.
