This is an 85 watt floodlight made by GE, that has a built-in photocell that turns it on/off depending on the amount of light that is around the bulb. The photocell was carefully designed so that it would not turn the bulb off because of the bulb's own light. This is a halogen floodlight, so it is made of thick glass, to protect people from a rupture of the internal halogen bulb. These lamps were not very effective because most floodlights are usually placed indoors in dark places, so the result was that it will stay lit on low power when indoors. It doesn't go directly from on to off; It turns on progressively as light is needed. This one is at least 5 years old (7-5 years), and most likely out of production.
