Soldering the LED chip and polarity with 99.99% gold wire.
Using famous brand chip inside for lighting source.
Copper LED frame provides better heat dissipation function for LED so that it will have longer lifespan.
660nm Wavelength 5730 SMD LED
660nm LED means the light emitting diode that with 660nm wavelength. But when we discusse about the 660nm LED, it's about the peak wavelength. And each single LED have their own wavelength. For whole batch of red SMD LED in 660nm. There will have a range on it. In this 5730FR667P8L14P2, The range is 665nm to 670nm. 665nm LED lights are commonly used in LED grow lights. This specific wavelength falls within the red spectrum and is known to promote photosynthesis and flowering in plants.
It helps in the absorption of light energy needed for plant growth and development. Therefore, 665nm LED lights are widely used in indoor gardening and commercial horticulture for cultivating various types of plants.
