365 nm vs 395 nm UV LED Strip Lights
Our business is platinum photographic printing. I have 10 meters of 395nm strip. I am building an exposure unit with those. I believe the sensitive area for a pt. print is around 300 to 400 nm and glass is about 300 nm cut off. The glass is needed. Is there an advantage to using 365 nm UV strips? How much, if any, can voltage boost output -- considering air cooling? is there an advantage to using UV floods?
We don't have any official support for exposure unit installations, but other customers have reported much success using our UV LED strip lights for screen printing applications.
We believe that the 365 nm may be a more effective wavelength given that this wavelength level is a "deeper" UV-A wavelength that may be a closer overlap with the sensitivity range of various emulsion materials. We do not believe that the 300 nm cut-off glass will be an issue.
The products are rated at 12 volts only, and over-drive is not supported and will likely lead to premature failure, even with sufficient cooling.
The UV floods can also be an option, though achieving uniformity may be a bit more challenging. For example, please see our irradiance charts for the UV flood light below:
