Are there any UV flashlights that use a smaller wavelength than 365 nm, that you know off? Closer to uvb
Everything I see on the net is 365-400
Thanks
not really, not only true uvb leds are very expensive per watt, but they are not safe for an average consumer either, no manufacturer wants that liability. YUou can buy leds yourself and build a light with them, just make sure you use quartz glass, anything else will not pass low bandwidth
ok I’ll just get the malkoff
What is your intended use? Most florescent objects react to specific wavelengths of light. 365nm is good for a whole bunch of stuff so going lower often doesn’t result in meaningful gains, especially given the high cost of MW LEDs.
