Key Differences
A bulb is the source of light, often containing a filament or a set of LEDs that illuminates when electricity passes through it, whereas a lamp is the complete apparatus that includes a bulb as well as additional components such as a base, shade, and power mechanism.
Bulbs are primarily categorized by their light source, such as incandescent, fluorescent, or LED, while lamps are distinguished by their design and functionality, including table lamps, floor lamps, and wall lamps.
While bulbs are designed to be replaceable components of lamps, offering various levels of brightness and color temperatures, lamps are designed to enhance the aesthetic and functionality of a space, incorporating styles that complement decor and provide desired lighting effects.
Bulbs are evaluated based on their energy efficiency, lifespan, and light output, whereas lamps are often chosen based on their material, design, and the type of lighting they provide, whether it's task, ambient, or accent lighting.
In terms of technological advancements, bulbs have seen significant innovations, such as the transition from incandescent to LED technology, which offers greater energy efficiency and longevity. Lamps, on the other hand, have evolved in design, incorporating smart technology that allows for adjustable light settings and integration with home automation systems.
