LED Grow Light for all types of plants with adjustable spectrum. Suitable for hydroponics applications, indoors cultivation of chili and herbs, house plants and vivariums of special plants like orchids. Effective 1W LED chips with optical lenses and optimized combination of blue, orange and red wavelengths in a lightweight frame. Red LEDs can be turned off in order to support vegetative plant growth or to make light color neutral for photographing etc. Due to the amount of wide spectrum white LEDs, the light color is not too irritating to be used in normal living quarters even when all the red LEDs are on.
20W LED light fixture is designed to replace a fluorescent tube light fixture with 2-3 HO tubes and polished reflectors of similar length. As LED diods concentrate light more effectively to the desired direction, this light has a longer effective lighting distance than fluorescent tubes. It has a passive silent cooling system without integrated cooling fans.
Although externally similar with LED light fixtures offered under other brand names, this model is more advanced in both operation and light spectrum. Power switch has three positions; all LEDs on, only white + some blue LEDs on and power off. This allows the user to turn off colored LEDs and illuminate a target with white light. This is very useful for photographing. In other similar light fixtures, the switch operation is the opposite (blue LEDs on - all LEDs on – Off) and the fixture cannot be used to produce neutral white light. The light spectrum has been optimized for plants so there are both red and blue wavelength LED chips along white ones, while the other similar light fixtures only have blue and white LEDs.
This light type is originally designed for aquariums, due to which it has extendable legs can be mounted directly on aquarium glass walls (max. 12mm glass). Legs are removable and the holes for the rods go through the entire light fixture frame. This enables to make extended custom legs from any 4mm round steel or aluminum bar and to mount several light units to each other.
Due to the removable legs and their drilled through holes, this light fixture is easy to suspend with wire or even strong fishing line. Suspension is very usable mounting method for a grow light when plants are not grown in a terrarium or vivarium. As the transformer is in a separate unit which is connected to the 12V light panel with a quick-detachable cable, the light fixture is very lightweight. This makes suspension application easy and the light panel can be placed directly on plant vivarium or terrarium top cover with or without mounting legs.
NOTE!When the power of LED light is compared to the power of other lighting technologies (fluorescent tubes, metal halide lights etc.), it is important to understand the effect of different wavelengths to the visible light. Human eye observes white full spectrum light (comparable to the natural sunlight) as the brightest light. Specialized artificial light that only contains narrow spectrum of blue or red wavelengths or a full spectrum light that has a color temperature (K) significantly different than natural sun light is not observed to be as bright as white light, although the actual light radiation is the same. For example, a 20W daylight fluorescent tube with 6500K-10 000K spectrum (= cool white light) looks brighter than a 20W 2700K tube (= warm white / yellowish light) or a 20W red-blue plant tube when evaluated by human eye, although they produce exactly the same amounts of light energy.
LED light that has been designed to be optimal for live plants has LEDs that produce just red and blue wavelengths along white LEDs. The larger the portion of colored LEDs, the more optimal the light is for plant photosynthesis (in comparison to the consumed electricity), but the less bright the light seems to be to human eyes. Therefore, LED vs. other lights efficiency comparison means the efficiency from the plant photosynthesis perspective, not by a human eye observation. For example, if a LED fixture that has colored LEDs is said to be comparable in light power to three (3) fluorescent tubes, the light efficiency observed by human eye should be compared to three red-blue plant fluorescent tubes, not to three white daylight tubes.
