Whose using Xenons?

I was always told to use mirrors whenever placing a xenon source at an extreme or odd angle, so I would say yes you probably should use mirrors.

Get someone to sit in front of a car in day light, and light his face using the car]s beam. If anyone has done
it already I would be glad if you could post pictures of the result. Thanks in advance.

Nothing like a Xenon for getting the effect of rays of sunlight.

As for the mirror, you are correct. Use a mirror when the light is tilted to extreme angles and be concious of the mirror's distance from the unit. Closer is better with xenons. I'm sure that you know how hot the beam can get at certain distances from the light. I witnessed an electricians baseball cap start to smoulder while the tip of his head was in the beam of light. It was funny...after everyone realized that he wasn't injured.
Changing xenon bulbs is a very hazardous job. Be sure whoever is changing the bulbs is wearing a face shield and heavy duty gloves. The bulbs can explode violently.

I've started using xenons to get nice clean shafts of light. I am really impressed with their punch and evenness. There is also a soft gentle quality to the beams that I don't see in a HMI 6k Par with a spot lens. I'd love to here other peoples experiences with Xenons. Also do I need to use mirrors when pointing straight down? I know I used to.
Xenon lamps are definitely rated for operation at only certain angles. Otherwise the plasma becomes unstable.
As most of you know, xenon lamps are the primary lightsource used for theatrical projection, and pretty much have taken over the spotlight market from carbon arc.
Here is an excellent technical manual that discusses xenon lamp operating parameters:
And a safety manual:
Remember, if you handle a xenon lamp without proper eye protection, it may be the last thing you will ever see!
