What's the difference between these BL colours? « on: August 05, 2024, 06:25:28 AM » Author: LightsAreBright27
I am confused about the difference between these bl colours in fluorescent tubes- Philips /01- https://www.lighting-gallery.net/gallery/displayimage.php?album=8026&pos=13&pid=244894 Philips /10- https://www.lighting-gallery.net/gallery/displayimage.php?album=8026&pos=55&pid=243816 Philips actinic BL- https://www.lighting-gallery.net/gallery/displayimage.php?album=8026&pos=38&pid=244045 Narva /073- https://www.lighting-gallery.net/gallery/displayimage.php?album=8026&pos=41&pid=243861 I have seen off-brand bl tubes either having the philips actinic bl colour or the narva bl colour. Can someone tell me the different wavelengths and purposes of each?

All of them are the same color. The Philips /10R have an internal reflector, and the Philips /01 is for the US and Canada markets. The light color actually comes from the mercury vapor. The phosphor emits in the UVA radiation only. These lamps are used in insect trappers and zappers and as an actinic lamp for uses like printing plates making.

I and LightsAreBright27 aren't banned from Google. I didn't noticed the Narrowband UVB on the Philips /01, but only the warnings for the American market.

Thanks for the link! I still don't understand the difference between the actinic bl and the more purplish bl. Also, I am not banned from Google, it just doesn't give proper links anymore (too much ai).
