New idea - glowing bulbs

[See previous]

The idea is so simple once you see it that your why-didn't-I-think-of-that circuit nearly shorts out from the overload:

Terrorist-Proof Lighting Illuminates Without Power

From the article: The gist of the idea is, "Let's paint bulbs with glow-in-the-dark paint so that they glow after you turn them off." What could be simpler than that? In this case, it would appear that they are mixing the glow-phosphor into the light-phosphor that is already present inside the fluorescent tube -- a nuance that is even more brilliant. It's not the sort of bulb you would want in a bedroom probably, but in any sort of office or industrial environment it would be perfect.

Comments:
I am in pain - that idea is so so obvious!
 
And great for practical jokes.
 
That idea has been around for quite awhile.
