The deep red 660 nm long wave red light has a high penetrating power. Compared to the invisible infrared 850 nanometers, 660 nanometer red light is lower in energy and has a milder effect on living organisms. The wavelength of 640nm-670nm deep red light is longer than 620nm-630nm normal red light, so 660nm red light is good for plant growth and medical treatments. 660nm deep red led strips provide uniform illumination coverage and are suitable for lighting applications that require uniform lumens over a large area.

• 850nm led light: It is infrared light and is not visible to the naked eye. Although called infrared light, 850nm LEDs emit infrared light along with a weak visible red light.

Moreover, the light of 810nm LED strip, 850nm LED strip, and 940nm LED strip is invisible to the human eye, so this IR LED strip type is usually used for lighting that needs to be unnoticed.

Near-infrared light, ranging up to 1100 nm, penetrates deeper into tissues and can aid in muscle recovery and pain relief.

LED lights can emit 660nm red color light, SMD2835, SMD3528, and SMD5050 can do red light. Using these low voltage DC 12V or 24V deep red 660nm led light strips for light therapy can promote cell regeneration and repair, anti-inflammation, improve blood circulation, reduce pain, and promote wound healing. LED 660nm red light therapy has a positive effect on both skin health and mental health. In plant growth lighting, red light around 660nm has a significant effect on photosynthesis, especially under certain 500nm blue light conditions, which can promote plant growth and flowering. Sometimes 660nm mixed with 3000K/3500K warm white light is also chosen to help vegetable growth.

• 940nm led light: It also belongs to infrared light, which is not visible to the naked eye. Compared with 850nm LEDs, 940nm LEDs emit light at a minimum wavelength at which the intensity of the light it emits reaches a value of 0 is higher than the visible long wavelength of 760nm, so the light emitted by 940nm LEDs is not visible to the human eye.

In the visible light spectrum, the wavelength of red light ranges from about 620nm to 750nm. Compared to 660nm bright deep red light, 730nm far red light is closer to the boundary of infrared light.

730nm light promotes shade avoidance, makes plants taller, and regulates flowering cycles. This wavelength of red light also penetrates deeply into the plant canopy, which enhances photosynthesis and is especially beneficial for ornamental flowers.

In most houses, a medium beam angle, between 40° and 60°, is sufficient to light up a room properly. However, the actual beam angle can vary slightly depending ...

660nm deep red led strip is visible red light (620nm to 700nm). This red light therapy acts on the skin surface (penetrating your body to a depth of about 8 to 10 mm) to stimulate cell regeneration (collagen) and can treat skin conditions such as acne, wrinkles, and age spots, and heal wounds.

The 850nm near infrared light waves have significant applications in the field of phototherapy. 850nm red light therapy penetrates deep into the skin and is absorbed by the water, proteins and pigments in the tissues to generate heat energy. This heat energy stimulates circulation, increases cellular activity, and acts as an inhibitor of inflammation and pathological tissue.

Both 940nm and 850nm near infrared light are invisible and both can be used in night vision systems. The difference is that 940nm is almost completely invisible to the naked eye and cell phone cameras, therefore 940nm is better suited for surveillance scenarios where concealment is required.

Infrared 850 nm IR LED strip light is a kind of strip light specialized in emitting 850 nm wavelength near infrared light with low power consumption and high efficiency, which can be bent, cut and extended according to your needs. 850nm LED has a weak visible red light in dim environment, which is easy to calibrate or confirm the working status, and it is suitable for night-vision equipments, CCTV cameras, security monitoring, machine vision, etc.

The radiation intensity of 850nm is about 2-3 times higher than that of 940nm, so 850nm infrared light will be a bit brighter. Therefore, 850nm will have a red burst situation, LED chip will appear visible red dot in the work, 940nm is not have. This can be a disadvantage in infrared lighting applications, but in some cases this visibility can help to confirm the operational status of the IR led strip.

660nm belongs to visible light, the color is deep red; while 850 nm light belongs to invisible light, which can only be seen under the camera equipment. 850nm IR light wavelength is more powerful than 660nm wavelength to penetrate the tissue, and able to reach the deeper tissues of the body. Therefore, 660nm led strip is commonly used for surface skin problems and cosmetic issues, while 850nm infrared light is more suitable for deeper tissue treatments.

In agriculture, 660nm red light led strip and 730nm far-red led strip are used in plant growth lighting systems to promote plant photosynthesis.

940nm wavelength is located in the infrared lights spectral range, invisible to the naked eye. 940nm invisible infrared technology is widely utilized in applications such as night vision devices, remote controls, security cameras, and other applications to provide clear night vision while maintaining surveillance invisibility. The 940nm IR light has a good transmission capacity in the atmosphere, which makes it suitable for long-distance transmission and telephoto shooting.

Our infrared (IR) and near-infrared (NIR) light led strips are available in 660nm, 730nm, 810nm, 850nm, and 940nm wavelengths. These wavelengths are often used in light therapy (photobiomodulation therapy), plant growth, and night vision systems for security cameras.

850nm is a wavelength of light that lies in the near-infrared spectral range (800nm~1500nm), and this band of light is invisible to the human eye. So you can't see with your naked eye whether the 850nm LED strip or light is working or not. But you can see the 850nm LED light beads emitting a faint pinkish reddish dimming light under the cell phone camera and other devices.
