High-Efficiency Light Bulb

A lightbulb comprising:

• a base having an enclosure with a socket means at a lower end thereof and a base connector means at an upper end thereof, the enclosure including a circuit means mounted therein for conveying electric power from the socket means to the connector means;
• and
• a selectively detachable bulb means having a bulb connector means mechanically and electrically cooperative with the base connector means to secure the bulb means to the base and conduct electrical power therethrough, the bulb means further including a glass bulb fixed to the bulb connector means and enclosing a non-opaque, substantially hollow capsule that includes within a filament and a non-reactive gas sealed therein, a pair of lead wires traversing the capsule and electrically connected to the bulb connector means;
• whereby with the bulb means coupled to the base and power applied to the socket means, electrical power flows through the socket means, each connector means, the lead wires, and the filament to light the lightbulb.
