Tips: With 20mm PCB ,it means it has been soldering tin,saving your cost and time,
 ( LED and PCB had soldering together )

395-400 nm: high brightness, poor fluorescence effect, high cost performance, suitable for checking banknotes, grasping scorpion, curing, fluorescent reflection of special substances, etc.

When 395-405nm is luminous, the brightness of the naked eye is higher, the color is partial blue, and the fluorescence effect is slightly worse. It is suitable for RMB checking, grasping scorpion UV curing nail and special substances fluorescence reflection.
 
410-420nm luminance is visible to the naked eye with high color, color, blue, and blue. It can not be used for LED plant light fishing water aquarium fish tank lighting etc.

380-385nm: light to the naked eye can be seen a little more purple light, light slightly more than 365, with good fluorescent effect, cost-effective, suitable for checks, bills, stamps, tobacco and wine cosmetics, fluorescent identification, jade amber and amber color.
 
355-400 nm: high brightness, poor fluorescence effect, high cost performance, suitable for checking banknotes, grasping scorpion, curing, fluorescent reflection of special substances, etc.
