The Samsung LM301H EVO is considered better than the Samsung LM301B for several reasons:
Efficiency: The Samsung LM301H EVO has a higher efficacy (efficiency) compared to the Samsung LM301B. The LM301H EVO has an efficacy of up to 3.10 μmol/J, whereas the LM301B has an efficacy of up to 2.92 μmol/J. This means that the LM301H EVO can produce more light output per watt of energy consumed, which can result in significant energy savings and increased overall performance.
Spectral output: The LM301H EVO has a broader and more uniform spectral output compared to the LM301B. This means that the LM301H EVO can provide a wider range of light wavelengths, which can be beneficial for plant growth and overall health.
Durability: The LM301H EVO is designed to be more durable and long-lasting compared to the LM301B. It has a higher operating temperature range of -40°C to 85°C, compared to the LM301B's range of -30°C to 85°C. This means that the LM301H EVO can withstand more extreme temperature conditions, which can increase its lifespan and reliability.
Overall, while the LM301B is still a great LED for plant growth, the LM301H EVO is a more advanced and efficient LED that offers several advantages over its predecessor.
