Need help : brightness of UV flashlights comparative to the white or blue LEDs ?

I was wondering how's the brightness of an UV flashlight comparative to white LEDs one ? I have never had such a light.
I had 2 INOVA X5s : one white and one with blue LEDs...I had the impression that the blue one was a bit brighter than the other one.
The same impression I have it when comparing my 2 T3 TIROS INOVAs : white LED and blue LED.

I know the UV is used to check the money and some liquids ...but I was curious about the brightness...
How's the tint also ? Purplish-blue ?

Any suggestion would be much appreciated ! Thank you !

You can't see UV, so the light(the violet that you can see) will appear dimmer for the same watt imput.

Hi Radu,

There are some interesting comments on the Inova X5 UV flashlight from owners posted on Amazon.com.
