Types of Light Bulbs and Their Characteristics

The video tutorial explains the differences between incandescent, halogen, fluorescent, and LED bulbs. Incandescent bulbs are simple but inefficient, converting most energy to heat. Halogen bulbs are more efficient and last longer but get very hot. Fluorescent lamps are efficient but contain mercury. LEDs are the most efficient and long-lasting, using significantly less power. The video concludes with recommendations based on energy savings and lighting needs.

Which type of light bulb is known for its simplicity but inefficiency?
