Pics of a D2S Xenon Bulb

I was playing with the camera taking some pictures tonight when I was changing the lights and thought I'd share what I came up with.

The Good:
Here's a picture of a perfectly good HID bulb. Notice how round and well shaped the light is. The glass is evenly lit around the light arc:

Taken at F8 and 1/2000 sec.

The Bad:
Now here is a pic of a bulb on it's way out. Notice there is a fog on the glass and it is not evenly lit anymore. Even the bulb base is now lit up because of this. Some of the xenon gas has leaked and residue is forming inside the glass of the bulb. As time goes by the glass will deteriorate and fail.

Taken at F8 and 1/2000 sec.

The Beautiful:
Here is a a pic of an HID just after it is turned off after being on for a minute. Notice the bottom electrode is still glowing from the heat and I think some of the xenon gas cooling down. This lasts for only a few seconds of turning the bulb off.

Taken at F2 and 15 seconds.
