LM301H EVO QS Series full spectrum led grow lights
The LM301H EVO grow lights is excellent for growers who require the finest illumination quality. ICEVER's EVO series is an improvement over the previously launched QS and QB series, since it replaces all primary LED chips with Samsung LM301H EVO. Furthermore, red and blue light chips from Osram and Seoul have been incorporated to broaden the spectrum in these areas, making it even more ideal for cannabis production. The LM301H EVO grow lights utilizes high-quality LED chips, making it one of the most comprehensive and well-suited devices for plant supplementary lighting on the market today.

The LM301H EVO grow lights features both Quantum Board and Grow Bar designs, as well as the popular dimming knob and independent power/UV/IR/R switches seen in the QB and QS series. Furthermore, the LM301H EVO series is compatible with the smart control systems used in the QB and QS series, allowing gardeners to monitor grow tent inside conditions and alter the growing environment remotely at all times.
WHY CHOOSE LM301H EVO SERIES ？
Previously, common LED chips utilized in the growing market, such as the LM301B, LM561C, and Cree CXA3070, were created and developed for general illumination and displays rather than plant grow lighting. However, because of their superior performance, many individual growers widely accepted them as additional light sources for grow light. Because these chips were regularly cited in many growing-related forums or personal blogs, they gained appeal among plant light producers and became more included into LED grow lights.

However, general-purpose illumination LED chips are developed with human vision in mind, having many functions that are unneeded for a plant. Furthermore, plants require a certain light spectrum that is difficult for the human eye to identify. As a result, more worldwide LED chip makers, including Samsung, Osram, and Cree, have begun to invest in plant lighting research and development.

The LM301H EVO is a professional LED chip launched by Samsung for full-spectrum grow lights, so the grow lights using this professional chip more suitable for cultivation. This is especially true for plants like cannabis, which require the synthesis of special compounds. Compared to our other grow light series, the LM301H EVO full-spectrum LED grow lights have higher PPE, longer lifespan, and a more excellent spectrum.

  • ⭐⭐⭐LM301H EVO led grow lights have Industry-leading Spectrum
    17270766104650Based on the official technical specifications and related documents of Samsung's LM301H EVO, it is evident that spectrum optimization is the primary goal of the LM301H-EVO. A comparison reveals a clear shift in the spectrum (shown in Samsung’s official image, presumably of the Mint white model LED). Samsung has shifted the spectrum towards the left, moving the blue light peak to 437nm.

    Samsung believes that compared to the 450nm spectrum peak, a 437nm spectrum peak is more suitable for the ratio of chlorophyll A and B and for photosynthesis. This view aligns with Bridgelux’s perspective that the 437nm blue light has a more direct impact on photomorphogenesis in plants, particularly in regulating the plant’s biological clock and photoreceptive responses. Grow lights using the LM301H EVO chip can perform better in blue light.1727076618339117270766204362

    Additionally, the red light region in the LM301H-EVO is significantly reduced, providing the full spectrum led grow lighting industry with a purer choice. Grow lights OEM manufacturer can more precisely customize the spectrum using a tailored LED chip mix, making the adjustment process of grow light spectrum more controllable. Currently, LM301H-EVO is highly popular among DIY grow light enthusiasts and a frequent topic of discussion in forums. Increasing amounts of real-world data and case studies are proving the effectiveness of LM301H-EVO for plant cultivation. More and more individual growers or farms are willing to incorporate LM301H-EVO grow lights into their growing systems or indoor grow tents for cannabis. Due to market demand, LM301H-EVO has already been included in the customization range. Feel free to contact Icever for inquiries.
  • ⭐⭐The lifespan of grow light has been further extended
    The other optimization directions of the LM301H-EVO grow light are also based on the actual experiences of growers, including the heat dissipation and sulfur resistance characteristics of the LED chips:


    1727076950978 Heat Dissipation
    In past LED packaging technologies, the electrodes were located on top of the chip, which affected both the light output and heat dissipation of the LED chips. The Flip-chip technology places the chip upside down, with the electrode facing downwards, effectively alleviating heat accumulation and improving the overall stability of the LED. This Flip-chip technology, mentioned in the Samsung LM301H-EVO report, was originally used in high-brightness display applications but was introduced into the plant light design field due to its advantages. For more information about Flip-chip technology, refer to Stirling, G., Toh, H., & Stirling, A. (2020). Lighting system with optimized color output for horticulture. U.S. Patent No. 20200388728. Retrieved from Justia Patents.
    The optimization of heat dissipation is aimed at reducing ventilation costs for growers. Whether in small indoor grow tents or large-scale grow operations, heat dissipation is crucial. Currently, mainstream heat dissipation relies primarily on two methods: product heat conduction and ventilation system heat dissipation. Optimizing the heat dissipation of LED chips can alleviate this issue at its source, reducing the costs users might incur in their ventilation systems.

    a general rule of thumb we use in the lighting industry is that for every three watts of lighting reduced, air conditioning is reduced by one watt. If we assume a ~40% reduction in lighting watts compared to HID, this works out to a potential 13% reduction in electricity consumed by your HVAC system when switching to LED grow lights. Your actual results may vary. Environmental grow room configuration, airflow, and many other factors influence HVAC needs and related HVAC energy consumption


    Sulfur Resistance
    17270769647292The Samsung LM301H-EVO also has sulfur resistance as an enhancement direction. This is primarily to solve the issue of sulfides in fertilizers or other plant supplements volatilizing in high humidity conditions during cannabis production, which can adhere to the surface of the LED grow light and degrade light quality (Especially for wavelengths with weaker penetration abilities, this is why we need to regularly clean the surfaces inside the grow tent and the grow lights within the grow tent.).

    This is accomplished using the Titanium Oxide Coating depicted in the image
     
    By adopting these two enhancements, the Samsung LM301H-EVO full spectrum led grow lights increase the lifespan of LED chips from both internal and exterior perspectives. The internal Flip-chip technology improves heat dissipation and stability, guaranteeing that the product functions at the proper temperature. Combined with active and passive cooling methods, this significantly prolongs the lifespan of the grow light. The external sulfur-resistant material protects the LED chips from corrosion by sulfides, which is also beneficial for extending the product’s lifespan and reducing the frequency of replacements. This is why ICEVER choses the Samsung LM301H-EVO as the primary lighting chip for this grow light series.
     
  • LM301H EVO grow lights have Industry-leading PPE
    If you're using a grow tent for indoor cultivation, it’s easy to find from your electricity bill that the component of your grow tent kit consuming the most energy is your full-spectrum grow light. Most of the cost recovery from LED grow lights comes from electrical service savings, which includes both the ventilation and lighting systems.
     
    The PPE of Samsung’s LM301H EVO chip reaches 3.14 μmol/J. A higher PPE value means that the LED grow light can produce more photons using the same amount of electrical energy (for instance, the maximum PPF of 3000K LED chips is 0.557, and for 5000K LED chips, it is 0.587). To explain this in a more straightforward way, it allows you to save electricity during future cultivation activities. Grow lights equipped with the Samsung LM301H EVO chip can help you conserve energy in the future while also delivering superior lighting for your plants.17270774463223

    According to the official experimental data from Samsung, we can see that the PPE of 5000K LED chips improves by an average of 2% when driven by a 65mA current and under 25°C conditions. Additionally, as the driving current increases, the 437nm wavelength LED chips are able to maintain high PPE levels. Therefore, you don’t need to worry too much about the lighting stability of the LM301H EVO grow lights.
  • Two designs that align with growers' usage habits.

    LM301H EVO QB Series The LM301H EVO Series grow lights currently come in two different designs: the more concentrated quantum board (QB) and the grow bar (QS), which has a more evenly distributed light source.



    LM301H EVO QS Series full spectrum LED grow lightThe quantum board has a smaller size, taking up less space overall, and the emitted light is more focused. This type of grow light can be chosen with slightly lower power, paired with a small grow tent. This way, light can be maximized in the small space, providing plants with comprehensive illumination.




    The grow bar, on the other hand, offers a wider coverage area with more evenly distributed light, but it is larger in size compared to the quantum board. LM301H EVO V3 PRO Series full spectrum LED grow light

     

     

    As mentioned in the QS and V3 pro introduction, this design can greatly reduce the difficulty of use for the user, making it ideal for scenarios where multiple grow lights are used together. Using a grow bar in your indoor grow tent kit is also a good choice, but please note that grow bars are more suitable for medium to large grow tents.
  • The LM301H EVO grow light features smart control capabilities
    The LM301H EVO grow light supports smart control, including both Bluetooth and Wi-Fi modes. Both options allow users to adjust the lighting combination modes and output power through their mobile phones, ensuring that they can monitor the status of their plants at any time.
