LED grow light with adjustable spectrum features and advantages
They are adjustable spectrum LED grow lights composed of 12 bar modules. They are suitable for the entire growth stage of plants, from seedling to production to flowering. They are also suitable for growing high-value crops such as marijuana, tomatoes, and strawberries.
✅ Multiple spectrum adjustment designs: Customized from single-way to three-way dimming buttons. This allows you to reasonably and accurately adjust the spectrum according to different growth stages, such as seedling, growth, and flowering, better promote photosynthesis, accelerate plant growth, and improve yield and quality.
✅ Modular structure: Each light bar is independently plugged in and operated. It is easy to maintain, saving time for replacement and assembly. Plug and play. Compact packaging saves transportation costs.
✅ High PPFD output: The PPF per second reaches 3050 μmol/s, and the PPFD can cover 700–2400 μmol/m²/s, which can meet the growth needs of different plants. Accelerate the photosynthesis of branches and leaves and maximize the yield per square meter.
✅ Wide range of use scenarios: home indoor tents, vertical farms, three-dimensional growth racks, container farms, commercial cannabis, indoor greenhouses, and other planting sites.

Adjustable spectrum LED lights Product Detail

High PPFD Analysis
1. Hanging height 30cm (12")
The PPFD from the center to the edge is 1783~810 μmol/m²/s, and the data is a smooth transition, indicating that the lighting is uniform, and this high PPFD LED grow light can meet the high light requirements of the cannabis flowering period.
2. Hanging height 40cm (16")
After increasing the hanging height, the centre area value is still 1600+ μmol/m²/s, and the edge value is 1000 μmol/m²/s. After raising the height, the PPFD value is also stable. Therefore, according to the needs of the plants, users can narrow or expand the range of lighting.
Appearance details design
1. Integrated driver design: the driver power supply and the main body of the lamp are integrated in design, which reduces the risk of the power supply being damp and prolongs the service life; at the same time, it prevents the wires from leaking out, which makes the whole lamp's appearance neater and more beautiful, which is in line with the aesthetic of modern growers.
2. Plug-in module: Make the package compact, save space, reduce transportation costs, and reduce wear and tear; assembly, replacement,t and maintenance are easy and quick.
3. Individual UV Module: 2 UV spectrum light strips are coated with purple color, which makes it easy for users to better identify and rationally use the UV spectrum.
