Reading At Night By Invisible Light

Among the more pointless things I’ve done recently is install a blacklight CFL in my bedside lamp. This is to encourage me to take up reading books again. Do you follow? It’s a simple idea really. I’ve grown so used in the last decade or so to reading from screens that paper seems a bit weird now. But turn on a UV lamp and what happens to a book? It glows. Like a screen!

Bleaching agents in the paper must make it fluoresce. Not all the fibres seem to have it equally though, and the page takes on an oddly speckled, grainy look. It is bright enough to read by though, just about.

All right to be honest this isn’t really why I got the bulb. I bought it because I’d never seen a blacklight CFL before, it wasn’t expensive, and I thought it was too interesting not to buy. In action it seems more violet than invisible, but white things around the room glow in an eerie way. The shirts I have hanging look particularly fierce, and the pale neon emanating from my map of Europe hints at the trippy possibilities. This all gives the room an… interesting look – somewhere between clinical laboratory and tatty ghost train.

And I notice that it actually makes the photochromic lenses of my glasses go dark, so it really does seem to put out a healthy (?) amount of ultraviolet light. Perhaps if I sleep with it on I’ll get a tan this summer.
