The SpectraBULB X20 is a 21W LED bulb that effectively illuminates about 30x30 cm. For a 60x60 cm space, a single one will not be enough for uniform coverage; multiple bulbs would need to be placed, which will slightly increase consumption. It includes silent fans that help prevent overheating, which is appreciated in a small volume. Its modest power also ensures reasonable energy consumption. In summary, for a 60x60 micro-cultivation, it can be suitable but requires good arrangement and proper ventilation to optimize light without creating excessive heat.
The SpectraBULB X20 20W is perfectly suited for a 40x40 cm grow tent. Its full spectrum effectively supports both growth and flowering. For this small area, you have an excellent balance between light power, low heat production, and lighting quality, ideal for maximizing your plants' development without overcrowding the space.
The SpectraBULB X20 horticultural LED bulb from GreenVisuaLED delivers a power of 20W with a neutral horticultural spectrum, close to natural light, often around 3000K. It is designed to cover an area of approximately 30 x 30 cm.
For a 60 x 60 cm cultivation area, it is recommended to use multiple bulbs to ensure homogeneous and adequate brightness. The precise light intensity in lumens is not specified, but this COB LED provides effective lighting with a 60° angle suitable for indoor cultivation.
In summary, for this area, plan for at least four SpectraBULB X20 to ensure good plant development through optimal lighting.
This feature makes the SpectraBULB X20 an economical and effective choice for small indoor crops, with a coverage suitable for an area of approximately 30x30 cm.
The SpectraBULB X20 by GreenVisuaLED is ideal for covering a surface of 30 x 30 cm indoors. For optimal lighting and healthy growth, place it about 40 cm above the foliage. It is perfect for small crops, such as orchids, houseplants, or bonsais.
The SpectraBULB X20 features an efficient heat sink that provides passive and silent cooling, without a fan. This design effectively manages the heat generated by its LEDs, even in confined environments. With a moderate power of 20W, heat generation remains limited, reducing the risk of overheating.
To ensure optimal lifespan and stable performance, it is recommended to maintain minimal airflow around the bulb, even in tight spaces. This simple yet effective combination ensures reliable heat dissipation, securing your indoor cultivation.
For the horticultural bulb SpectraBULB X20 by GreenVisuaLED, the light output expressed in micromoles per second per watt (μmol/s/W) is unfortunately not officially communicated by the manufacturer. This data is essential for measuring its ability to stimulate photosynthesis, but it remains unavailable in public technical information.
For reference, similar modern horticultural LEDs typically show an output between 1.5 and 3 μmol/s/W. The SpectraBULB X20, equipped with OSRAM COB LEDs and a neutral white horticultural spectrum, is designed to offer efficiency suitable for an area of about 30 x 30 cm, suggesting balanced horticultural performance although no precise figures are published.
For accurate calculation or in-depth technical comparison, we recommend using a certified PPFD sensor to directly measure the photosynthetically active light flux in your setup.
The SpectraBULB X20 is a horticultural LED bulb with a standard E27 socket, making it compatible with most smart plugs or switches available on the market. Although it is not dimmable and does not have built-in home automation features, you can easily integrate it into your home automation system via these external accessories.
With this solution, it becomes very simple to automate its lighting and adjust schedules according to your needs, using platforms like Google Home, Alexa, or HomeKit. This method is ideal for optimizing the management of your horticultural lighting without technical complexity.
The COB technology combined with the 10 2W LED chips in the SpectraBULB X20 horticultural bulb offers a perfectly mixed light spectrum, very close to natural light. This ensures an optimal uniformity for several varieties grown simultaneously, preventing one plant from being favored at the expense of another.
The COB generates a powerful and concentrated flux with an angle of about 60°, significantly improving the light penetration through the foliage. The 2W chips complement this diffusion by ensuring uniform coverage of about 30x30 cm, limiting shadow areas and promoting balanced lighting on all plants.
Finally, this combination offers excellent energy efficiency at moderate power (20W), ideal for healthy, economical, and quiet indoor cultivation.
The SpectraBULB X20 is ideal for optimally illuminating an area of about 30 cm by 30 cm, or 0.09 m². This lighting allows for uniform growth thanks to a spectrum close to natural light and a diffusion angle of 60°, with a recommended distance of about 40 cm between the bulb and the plants.
To cover a larger area, such as 60x60 cm, it is necessary to use multiple bulbs to ensure homogeneous lighting and harmonious plant development indoors.
To effectively adjust the SpectraBULB X20 according to the growing phases, position the bulb about 40 cm above the foliage to ensure good light penetration without the risk of burning.
During the growth phase, prefer a lighting duration of 12 to 18 hours per day to stimulate photosynthesis. During flowering, reduce to about 12 hours to mimic the natural cycle and promote floral production.
The SpectraBULB X20 emits a fixed neutral white horticultural spectrum, suitable for all stages. As it is not dimmable, modulating the intensity is done by adjusting the distance to the plant. For more precise management, using connected bulbs with a dedicated application will allow you to optimize the duration and light intensity according to your needs.
For larger crops, it is recommended to install multiple bulbs while respecting their coverage area of about 30 x 30 cm, to ensure even lighting.
For the LED horticultural bulb SpectraBULB X20 from GreenVisuaLED, the total luminous flux in lumens is not specified, but its power consumption is 21 Watts, providing a white light close to natural light, very suitable for growth.
The optimal coverage on the ground is approximately 30 x 30 cm. For a dense cultivation, it is recommended to position the bulb about 40 cm above the foliage to ensure an even distribution of light on the plants.
The SpectraBULB X20 is designed to cover about 30 x 30 cm with a power of 20W and an angle of 60°. For a 60 x 60 cm grow tent, a single bulb will not be sufficient to ensure homogeneous and effective lighting.
For this space, it is recommended to use about 4 bulbs to achieve optimal coverage and support healthy growth of your plant. Otherwise, consider a more powerful lighting solution suited for this area to ensure uniform light.
The LED horticultural bulb SpectraBULB X20 - GreenVisuaLED consumes precisely between 20 and 21 Watts, making it an economical solution for indoor cultivation.
However, the total luminous flux in lumens is not officially communicated by the manufacturer, which is common for this type of lighting optimized for photosynthesis. This bulb uses OSRAM OSLON SSL COB LEDs with a 60° beam angle, efficiently illuminating an area of approximately 30 x 30 cm.
To assess its energy efficiency in cultivation, it is preferable to rely on a direct measurement of the PPFD (photosynthetic photon flux density) with a specialized sensor, as the yield in micromoles per joule is not specified but is generally between 1.5 and 3 μmol/s/W for similar LEDs.
The SpectraBULB X20 LED horticultural bulb is designed to last approximately 50,000 hours before its performance begins to decline significantly. This longevity corresponds to several years of indoor use, thanks to its 20-watt Full-Spectrum COB LEDs and quality manufacturing.
It comes with a 2-year commercial warranty. To best preserve its performance, it is recommended to position it about 40 cm from the plants' canopy and ensure good ventilation around the bulb.
