So I have heard that fluorophores glow under UV light, so I was wondering what is the minimum amount of UV light needed to make the fluorophores glow and what would be the minimum amount of electricity required to make that much amount of UV light.

Also, is there any other type of light that makes fluorophores glow but requires a lesser amount of electricity?

    $\begingroup$ There is no minimum, per se, though you will encounter a limit of detection issue as you decrease the UV excitation light intensity. As for electricity, there are various electrically powered UV light sources, e.g., UV LEDs, UV fluorescent lamps, UV lasers, etc. Their efficiencies vary greatly. $\endgroup$ – Ed V Apr 16 at 12:25
  • $\begingroup$ @EdV Could you suggest to me a device that releases UV light and is small, light, inexpensive, and uses less electricity than an LED or at least a similar voltage to it? $\endgroup$ – Aster17 Apr 16 at 13:05
  • $\begingroup$ What specific chromophore are you interested in? You may be able to tailor the light source specifically to the absorbance wavelength of your chromophore to reduce power consumption by the lamp. $\endgroup$ – Andrew Apr 16 at 13:13
  • $\begingroup$ @Andrew I don't have an exact fluorophore or chromophore, but rather a mixture of 3 fluorophores, quinine, rhodamine B and fluoroscecin. $\endgroup$ – Aster17 Apr 16 at 13:14
