Automatic On/Off SAF-T-GARD Floodlight

This is an 85 watt floodlight made by GE, which is unique in that it has a built-in light sensor to turn the bulb on or off automatically, depending on the amount of ambient light. This photocell sensor was mounted on a gray plastic strip on the side of the bulb, and it had to be designed in such a way that the bulb's own light would not turn it off.

There is a small halogen capsule inside this bulb. Early halogen capsules like this one can suddenly explode, usually towards the end of their life, and send shards flying everywhere. To mitigate this problem, early halogen bulbs have very thick glass envelopes (like on this bulb), which would nullify the effect of the halogen capsule exploding.

These bulbs do not work well indoors. If you do use it indoors, it will stay lit on low power during the day, thinking it's dusk or dawn. It doesn't go directly from on to off; Apparently it also has its own built-in dimmer. This one is from circa 1994, and is long gone from store shelves, much like most halogen light bulbs.
