Diameter: the xenon festoon light bulbs have a T3-1/4 bulb with a diameter of 13/32in
Length: the maximum overall length (MOL) is 1-22/32in
Color Rendering Index: CRI is 100 for all xenon light bulbs (100 is considered to be the best)
Good Lamp Life: 5,000 hours of rated life on average
Easy Lamp Handling: unlike a halogen light bulb the glass envelope of a xenon light bulb may be touched with bare hands (while the lamp is cool) without causing the lamp to fail prematurely
Lamp Choice: if the xenon festoon light bulbs are being used for Task Lighting or indirect lighting (under cabinets, under shelves, over cabinets, or inside cabinets), we recommend that you use frosted light bulbs. If, however, the xenon festoon light bulbs are being used for Accent Lighting to illuminate items that should “sparkle” (jewelry, china, crystal), then we recommend that you use clear light bulbs.

Do xenon festoon bulbs give off any UV and do they give off a lot off heat? We have these bulbs inside of 20 museum exhibit cases and I am concerned about the preservation of the objects on exhibit.
Thanks for your help.

Yes, xenon light bulbs emit heat and UV rays. Generally speaking, they do emit less heat/UV than halogen and incandescent sources.
If you are overly concerned about UV/heat I would strongly suggest using LED festoons instead because they emit far less heat and do not emit UV rays - http://www.pegasuslighting.com/led-festoon-base-light-bulbs.html

They do get hot; all xenon, halogen and incandescent in general produce much heat. For less heat use the much more expensive LEDs. Halogen bulbs give a fair amounts of UV and should have UV filters; they will fade paint pigments. I use over-wattage 12V halogens with filters and dimmers for my paintings - the UV is reduced (as is color temperature in general) when not at full intensity. Xenon emits UV in varying degrees depending on their design; I think you should put a UV impervious glass over the bulbs. You are correct to be concerned.
