What's the best LED chip for growing? Meet the powerful LM301H EVO LED chip.
The importance of high-quality chips in LED grow lights cannot be overstated, as they play a crucial role in determining the overall performance and success of indoor horticulture. They can help LED lights improve the efficiency of converting electrical energy into light available for plant growth, providing the most suitable spectrum for plant growth, thereby increasing crop yield.
As we have previously explained in another article, LEDs are built using a chip that performs an electroluminescence process, which transforms an electric current into photons.
However, the quality of LED chips on the market varies. It is best to choose an internationally renowned and market-tested brand such as Samsung, Bridgelux, Osram, and so on.
In this article, we will show you the best LED chip, the Samsung LM301H EVO, which was introduced in Mars Hydro's FC Quantum Bar LEDs.
Meet the pioneering LED chip brand in the market, Samsung
Samsung LED chips offer numerous advantages due to their advanced technology and innovation, such as high efficiency, long lifespan, excellent color reproduction, wide range of color temperatures, versatility in application, low heat emission, eco-friendliness, etc.
And Samsung continues to innovate and launch new series of chips, which are commonly used in LED grow lights:
Samsung LM301B Series: Optimized for horticultural lighting applications, providing high photosynthetic photon flux (PPF) and full-spectrum output for healthy plant growth.
Samsung LM301H Series: an improved version of the LM301B chips, offering higher efficiency and enhanced light output for horticultural and general lighting applications.
Based on the LM301H series chips, Samsung launched this year the LM301H EVO chip series, specially designed to meet the needs of growers, with a plant-centric spectrum, aiming to achieve stronger and more valuable harvests while consuming less energy.
To meet market demand and improve customers' planting efficiency, the Mars Hydro brand replaced the LM301B series chips originally used in the FC Quantum Bars series grow lights with the LM301H EVO series chips.
Why do Samsung LM301H EVO chips become the game-changer for LED grow lights?
The innovative plant-centric spectrum enhances plant photosynthesis and results in improved growth
Based on research into the significant impact of light spectra on plant growth, Samsung has innovatively developed a plant-centric spectrum with a peak at 437 nm, utilizing its world-class spectral engineering technology. Compared to the 450 nm spectral peak of normal full-spectrum LED lights, the 437 nm spectral peak is more suitable for the chlorophyll A and B ratio and photosynthesis.
And compared to common white LEDs or combinations of blue and red LEDs, LM301H EVO LEDs adopt a shorter wavelength plant-centric spectrum, promoting higher quality plant growth, larger and thicker leaves, and more robust fruits. It also stimulates secondary metabolites like phenols and flavonols, thereby improving the nutritional quality of plants.
For example, experimental results showed that tomatoes grown under the plant-centric spectrum of Samsung LM301H EVO chips had a whole shoot fresh weight of approximately 2.98 kg/plant, leaf area of approximately 1,966.2 cm²/plant, sugar content around 4.3%, and a yield of about 2.38 kg/plant. Compared to tomatoes grown under other normal full-spectrum LED lights, the whole shoot fresh weight increased by 20%, leaf area increased by 5%, sugar content increased by 15%, and yield increased by 25%.
Furthermore, this newly designed spectrum effectively inhibits the growth of microorganisms such as bacteria and fungi, resulting in longer storage for crops.
Top-tier market PPE facilitates increased crop yields while saving energy
To provide customers with a more efficient light, the PPE of the Samsung LM301H EVO chip has reached 3.14 μmol/J. What does a high PPE value indicate? It indicates that the LED chip can produce more usable light with less energy consumption, making it more efficient for plant growth.
The most important point is that LED chips with high PPE provide a greater amount of photosynthetically active photons, which directly contributes to increased plant growth rates. And plants receive more light energy to fuel photosynthesis, leading to higher biomass production and faster development.
Furthermore, the higher the PPE of LED chips, the more light energy will be available for plants to convert into chemical energy through photosynthesis. As a result, plants can produce more carbohydrates, which are essential for the development of fruits, flowers, and other plant products, leading to improved agricultural yields.
Additionally, LED chips with high PPE are more energy-efficient, as they produce more usable light per watt of electrical energy consumed. Growers can achieve the same light intensity and plant growth with lower energy consumption, leading to reduced electricity costs and a more sustainable cultivation operation.
Note: Although the PPE value of a single Samsung EVO chip is 3.14 μmol/J, the PPE of a complete grow light cannot reach this value. This is because the PPE value of a complete grow light is determined by the number and arrangement of chips in different grow light models. And the PPE of the entire light takes into account the combined efficiency of all chips, including losses incurred from optical losses and thermal management. It provides a more accurate representation of the actual energy efficiency of the entire lighting system.
Samsung LM301H EVO chips feature a special device architecture that ensures exceptional performance and stable operation for a wide range of lighting applications.
Flip-chip technology effectively manages heat and ensures stable operation
The Samsung LM301H EVO chip adopts flip-chip technology, where electrical connections are made directly to the front (emitting area) of the chip. This connection method allows for efficient heat dissipation, as the heat generated during operation can be more effectively conducted away from the active region. Additionally, due to their enhanced thermal management, flip-chip LED chips can handle higher power levels and current densities.
Technological expertise maintains performance in high-sulfur environments
Samsung LM301H EVO chips can resist corrosion caused by sulfur compounds, protecting delicate semiconductor layers from external contaminants. Even when exposed to high-sulfur environments, LED chips can ensure their lifespan and stability. According to tests, the flip-chip technology of EVO chips ensures that the chips maintain up to 99% of PPF (Photosynthetic Photon Flux) maintenance in high-sulfur environments.
What improvements have been made to the FC series LM301H EVO LEDs after the chip upgrade?
Enhanced efficiency: The Samsung EVO LED chips have improved the photosynthetic photon efficacy (PPE) of Mars Hydro FC series LED grow lights. This means that for every watt of electricity consumed, the grow lights can generate more usable light. It provides crops with sustainable, reliable, and stable energy efficiency, resulting in reduced electricity costs.
Increased PPFD and uniform light distribution: The Samsung LM301H EVO smart FC series grow LED offers impressive PPFD, making it ideal for commercial cultivation and enhancing flowering for superior crop quality and higher yields. The LED chips on each light bar are strategically arranged in an optimized pattern, ensuring uniform light distribution that promotes consistent plant growth, preventing concentrated hot spots in the center.
Optimized full spectrum, rich in red and blue: The distinct spectrum blend of FC series Samsung LM301H EVO LED grow lights includes a precise mixture of blue and red light, complemented by an ample amount of green light to promote optimal plant growth. Blue light stimulates vegetative growth and facilitates the accumulation of vital phytochemicals, while abundant red light accelerates the maturation process and enhances the quality of buds and flowers. Additionally, the inclusion of sufficient green light ensures essential plant development and improves light penetration throughout the canopy.
In conclusion, Samsung LM301H EVO chips have emerged as a game-changer in the LED grow light industry, revolutionizing indoor plant cultivation. With their advanced technology and superior performance, these chips offer numerous advantages that significantly impact plant growth and overall efficiency.
