Treegers LED - Grow Light: balanced lighting for indoor cultivation
The Treegers LED - Grow Light represents artificial lighting intended for indoor cultivation. Full spectrum light from this lighting system is applicable for plant cultivation at various stages of development. Two power configurations of the device are offered allowing the user to select the proper one depending on cultivation area and lighting needs.
Treegers GL300W and Treegers GL420W represent the same LED grow lighting technology offering different power configurations. These configurations make the devices suitable for controlled indoor cultivation systems requiring constant artificial lighting.
Two power configurations for different setups
There are two variants of the Treegers LED - Grow Light with 300W and 420W power configurations respectively. Different power levels allow for choosing the proper lamp for different conditions of lighting depending on the size of growing area, mounting height and other factors.
The 300W model is applicable for low-power configuration while the 420W version can be chosen for high-power setup. Both versions of the lamp are designed as LED grow light.
Even light distribution
Balanced light distribution across cultivation area is important when using artificial light for plant cultivation. The Treegers LED is designed for even light distribution across the area ensuring consistent illumination of plants.
Light distribution depends on mounting height and lamp positioning. It is possible to adjust the configuration depending on the area and development stage of the plants.
Passive cooling
The Treegers LED - Grow Light uses passive cooling system thus reducing the necessity of additional fans inside the lamp. Passive cooling makes the device simple and excludes the presence of additional mechanical elements in the lamp.
It is also an important aspect for indoor cultivation area since additional moving components or fan noise is undesirable. The device can be installed in any lighting setup without any problems.
Optional 0-10V dimming control
When the light intensity control is necessary, the optional Treegers Precise T Dimmer 0-10V can be used with Treegers lighting system. 0-10V dimming system allows adjusting the light output according to the setup needs.
Dimming gives additional control over the artificial light supply to the plants. It is useful when the light levels differ during cultivation of the plants at various development stages.
Flexible lighting configuration
Combination of Treegers LED grow lights and optional dimming system allows configuring lighting system to fit the needs of indoor cultivation area. Selection between 300W and 420W lamps is the first step while the addition of optional 0-10V dimmer gives the opportunity to control light intensity.
Treegers LED - Grow Light is applicable for full-spectrum, consistent distribution and controllable indoor lighting setup.
Differences between GL300W and GL420W
The GL300W and GL420W share the same full‑spectrum LEDs but mainly differ in power and coverage.
GL300W LED – when to choose
Best for smaller tents around 80×80 to 100×100 cm. Lower power draw (300W), less heat and still plenty of light for hobby growers and compact spaces.
GL420W LED – when to choose
Best for 100×100 to 120×120 cm or when you want higher light intensity on the same area. More light and potential yield, but also higher power use and heat.
In short: choose the GL300W for efficiency and small setups, the GL420W for maximum light and slightly larger areas.
