I saw some one mention the short arc xenon lamps, i have a working unit that was originally used for a fiber optic light pipe used in surgery, there is still a spot light you can buy called a Maxa Beam, I see them used in movies all the time and owned one till some one stole it, they use a 70 watt short arc and non of these should ever be operated with out some form of shield due to UV and the insane pressure the operate at. I have HID systems on my quad and they are more like a metal halide and operate at presures of over 400 psi and the final thing is i built a test fixture that uses the projection lamps from DLP tvs and projectors. Those lamps use xenon and mercury if memory serves and they call them UHP Ultra high pressure and they some times explode as a fail mode and the flying quartz can even cause additional damage in the tv, one unit i serviced destroyed the color wheel and light tunnel, i even found bits in the section with the color wheel. For there size the amount of light is amazing, Going back to HID I have 3 systems in service that i use for work lights, 9 watts, 21 watts and 35 watts. the 21 watt unit i made with a magnetic base for working on tv's, the little one is modded to fit inside a spot light that was halogen, the 9 watt emits allmost 900 lumens and on battery lasers about 4 times the run time, the 35 watt is just a hella de housing on a tripod with the ballast mounted under a carrying handle, it is a spare unit from the ones on my quad, about 3200 lumens i think and i have 3 on the quad. I also use a 100 watt metal halide for my bearded dragons and a modded 35 watt metal halide for my living room
sorry for drifting off topic but i love HID lamps as much as i love lasers.
Gas lasers and lamps I will still always love more then diode units as you can see it doing something, you can see the guts working if you will, glowing gas and high voltage always more fun
