Robin,
You may find the Popular Mechanics article following illuminating - pun intended.
http://www.popularmechanics.com/technology/gadgets/tests/incandescent-vs-compact-fluorescent-vs-led-ultimate-light-bulb-test#slide-1
Be sure to click the "view larger" beneath each photo of a light bulb to see the spectral curve, which will tell you how much UV light is present. Below (less than) 400 nm is UV. 400 nm and slightly above is violet visible light, which also is high energy but some is necessary for the appearance of true colors. Please notice that even for the same type of bulb, different manufacturers/models have different spectral curves, so it is possible to pick and choose for a particular application, but you must request the spectral curve from the manufacturer. Do not expect to walk into Home Depot and find this information.
Incandescent bulbs are being phased out by Federal law. It may, or may not - we will have to wait and see - still be possible to get incandescents when they are officially phased out, but finding alternatives is a good idea. I agree that the future probably is LEDs, but they still need a bit of development to have adequate spectral curves, light appearance, and reasonable cost. But they will get there eventually, assuming something better does not come along.

Subject: [MUSEUM-L] compact florescent bulbs in historic houses
For the historic house museum folks on the list -
What have you decided to do regarding using compact florescent bulbs in historic lamps and in the rooms of your historic houses? Are they safe to use in situ?
Thanks,
Robin
