Thick Glass Sylvania 50w Halogen Capsylite Bulb

This halogen bulb was made in the very late 90's. The glass envelope is heavily sculpted and very thick, and was manufactured by Sylvania. I used to like it so much that I originally chose it as the background picture for this website, back when I was a teenager and my collection was really small.

Curiously, a lot of sellers on eBay have put these up for auction thinking they are old, collectible bulbs, which they're really not. I have one only because I saw it in a store years ago, and I bought it at retail price, for a mere $5. A quick online search in March 2020 revealed that some people still have them in stock.

There is a small halogen capsule inside this bulb. Early halogen capsules could suddenly explode, usually towards the end of their life, and send hot shards flying everywhere, so in order to compensate for this problem, early halogen bulbs like this one had to have very thick glass, thick enough to readily contain such an explosion.
