1. What is 365nm and 395nm light?
2. Color and efficiency different
Before answering which 365nm or 395nm is better for your application, let's pay attention to what are the 365nm UV light and 395nm UV light, what are the difference between them, then we will know how to choose between 365nm and 395nm.
Table: Comparison of 365nm and 395nm light
|365nm light||pale blue-white color|| |
More powerful fluorescence：
Illuminate the tiny particles
|Higher||curing UV glue, UV varnish, surface curing of glue|
|395nm light||Brighter purple color|| |
Lower fluorescent effect:
Illuminate larger particles
|Lower||curing UV coatings and UV inks, determines the depth of curing|
As above image shows, the light can be divided into visible light, ultraviolet light, X-rays and infrared light according to the different wavelength range. The UV light between 100nm and 400nm can be further divided to UVA, UVB and UVC. The 200nm~280nm UVC light usually be used for surface, air and water disinfection; the 280nm~315nm UVB light can be used for plants lighting, medical training, and tanning. The closest UV light to visible light is UVA 315nm to 400nm, and it also called “black light” since it is still an invisible light.
365nm and 395nm UV light are usually be used for curing, and they both have strong penetrating power. Ultraviolet light in the 365nm band is often used for curing UV glue and UV varnish, and the 365nm band is often related to the surface curing of glue. The uv light in the 395nm band is often used for curing UV coatings and UV inks, and the 395nm band generally determines the depth of curing.
Economically, 365nm LEDs are generally expensive. Due to the complex manufacturing process of LED diodes, chips with a wavelength of 365 nm are inefficient and expensive. The exact price difference depends on the product type, but 365nm LEDs are generally more expensive. Therefore, if you prefer a brighter, wider beam and don't need to illuminate the smallest blemishes and spots, a 395 nm LED tape light would be a better fit.
On the other hand, 365nm light is the best UV lights for accurate applications such as currency analysis because it has less visible light and can display fluorescent substances more clearly. If you need a UV light to look for tiny fluorescent spot, the 365nm light is more suitable for you.
• Is 365nm light dangerous?
UV strips that emit above 365 nm emit less harm than UVB wavelengths because they emit in the UVA range. In general, the amount of UV light from a UV lamp is much less than the amount of UVA exposure obtained outdoors on a sunny day.
• Why do I need a 365nm uv light?
365nm light is ideal for a variety of applications such as UV curing, cleaning bathroom and bedroom stains, and cleaning pet stains on carpets. Our UV LEDs or black light strips are made of solid aluminum alloy. For UV lamps in the wavelength range above 365 nm, Suntech uses only pure professional LEDs.
• When do I need use 395nm light?
There are many reasons to choose a 395nm light. Because of their stronger light, you can use them to look for small stains at home or do clearance for your pet. And you can also use this to curing the ink to speed up drying.
