The large review about LED Grow lights

Changing housing spaces into a garden

People who love their plants, endeavor to create the best conditions for them to make them grow and flourish properly. Not only water but also right lighting is essential. A lot of plants depend on a continuously high supply of light. But the weather cannot always provide perfect circumstances. Spatial and lighting conditions also play an important role at home.

When there is not enough day light, special lights are required which provide the optimal supply. An LED lamp for plants is excellent for this purposes. The low energy consumption is the major advantage. The extremely energy-efficient grow lights can be used several times a day for a long period of time without having a guilty conscience about the environment or the fact that electricity costs might grow. Using the modern LED technology, the need of light can be covered for all plants, no matter where their are placed.

An additional advantage is the minimal development of heat. While other lamps can heat up and damage plants or need a lot of energy to cool down, LED lamps guarantee a gentle provision of light.

This lamp is predominantly meant for usage in greenhouses because it has 100 luminous diodes which each a power consumption of ca. 3 watt. The company Galaxyhydro also provides a grow light with 600 watt. Three quarters of the diodes included produce a red light. Additionally, infrared rays are also used. The growth of flowers, plants and vegetables should be influenced so that the cell division is stimulated. The infrared light shines less light in service than the other lights. This is a general feature and doesn’t represent any defects.

Comparing the German and the American Amazon website wich each other, it reveals that the American reviews are way better than the German ones when it comes to this lamp. According to the producer, the cooling system is supposed to be noiseless. There are two ventilators that are responsible for the heat dissipation and are approved by the independent testing center UL. The embedded IC prevents the light from flickering. The description of the product says that the light produces a bright light with a secured PAR-value. The life span of the grow light is up to 50.000 hours.

This product by VIPASPECTRA is a full spectrum grow light for all kinds of indoor plants, vegetables and flowers. It is ideal for all growth stages. This grow light offers a very bright light with 450 watt. The special thing about it is the fact that the case consists of a cooling heat sink to prevent heat extension. Extra high speed cooling fans run 70% cooler than HID lights. The producer claims that the full spectrum of this light provides plants with everything they desire in a natural sunlight. The product has the opportunity to switch between spectrums, the veg and a bloom switch.

In addition to that, reflector series by VIPASPECTRA are scientifically engineered to keep the balance with high PAR-value and a suitable coverage. It is not waterproof. The life span of this light lasts up to 100.000 hours. The scope of delivery includes one reflector, a hanging kit and a power cord of 6ft.

According to some reviews by customers, the power cord is too short so that the application area might be restricted. Furthermore, some complained about the lights being too hot for the plants or not hot enough so that their plants wouldn’t grow. Others claimed about flickering light or malfunctions of the buttons. The product is able to be controlled by a timer which enables individual adjustments. Most of the customers are satisfied with this product, though and would argue that it is worth its money due to its features.

Frequently Asked Questions about Grow lights

What effect does a grow lamp have?

Funktionsweise einer Pflanzenlampe

The LED grow lamp provides the required light to the plant for the energy extraction and hence for the thrive, if insolation doesn’t suffice. Through photosynthesis, a plant converts light and carbon dioxide into energy. Chlorophyll is responsible for this purpose. There are two different types of chlorophyll, namely chlorophyll a und chlorophyll b. Chlorophyll absorbs particularly light with the wavelength of 440 and 660 nm. Chlorophyll b absorbs particularly light with the wavelength of 460 and 630 nm. This wavelengths are at least necessary for a breeding of plants completely without sunlight.

Can a grow light support every plant?

Unterstützung von Pflanzen

Yes, a grow light can basically support every plant to grow and bloom. The wavelength of the light can have different effects on different kinds of plants. This is especially relevant for pros. All LEDs that sine in a blue and red spectrum, can be used for domestic purposes when there is a lack of daylight.

Which frequency ranges are being used?

Frequenzbereiche

Most of the LED grow lights shine in a spectral range of 430-500 nm and 610-730 nm. The first one appears bluish to the human eye, the second one reddish, so that a LED grow light emits a purple light. Some lamps only use two wavelengths of this scope, others cover the whole spectrum.

How many lumens does a plant need?

The amount of lumen of a LED grow light is irrelevant for the breeding of the plants because it only specifies how bright a lamp is for the human eye and does not reveal the amount of electro-magnetic energy which can be implemented by the plant.

Grow lights use a spectrum of wavelengths that is quite dark for the human ability to see but ideal for the energy extraction of plants. The energy which encounters plants as photon, is specified as photon flow density (PPFD) or rather as the PAR-value.

Which advantages does a LED grow light have over a sodium pressure lamp?

Compared to high pressure sodium lamp and metal halide lamps, LED grow lights seem to be quite expensive. But taking the life span of the lights into account, a LED lamp can provide a life span of partly 50.000 hours. Compared to a conventional lamp which can provide about 30.000 hours, it is obviously improved. The applied electricity is almost completely converted into light and hardly in heat by what the lamp does not overheat. This has the effect that no elaborate nor energy wasting cooling is needed. Oftentimes, a passive cooling is enough.

High pressure sodium lamps mainly produce light in a yellow-red spectrum and metal halide lamps particularly in a white-blue spectrum. Therefore, each of them support only phases of blooming or growing. LEDs however, enable a precise selection of color range so that it can be adapted specifically to the stadium of plant growth. A lot of LED grow lights have different modes whose light is perfectly adjusted to growth or bloom. Through the accuracy which LEDs produce wavelengths for the photosynthesis, the light efficiency is tremendously high. Almost all of the emitting light can be used by plants. Using conventional lamps, only half of the light can be absorbed.  

Enough light for every plant

Lighted Plant

LED grow lights help a lot of people to provide their plants with the needed supply of light, no matter if you are a gardener, a hobby gardener, if you just like plants or a shopkeeper of a flower shop. They speed up the upgrowth and take care of a dense growth. Ideal conditions can also be established for exotic plant species. The variety of products is huge and one can spend a lot of money for such a lamp without problems.

The products presented here are rather affordable. But more power costs more. Just as the grow lights by VIPASPECTRA, for example. Who is not in possession of a greenhouse and only wants to take care of indoor plants or vegetables like tomatoes, can choose a cheap version like the ones by TaoTronics. Both lamps are equipped with 12 LEDs ans are similar to each other. A good compromise to the other two lamps is the one by Galaxyhydro considering both, price as well as their power.

LED grow lights are perfectly suitable for darker rooms and places with too little light. During darker seasons, plants also get the light they require. Every plant can be nourished properly this way – reliable and economical thanks to the LED technology.
