What class of fixtures uses LED lights instead of conventional tungsten lamps?

LED fixtures are specifically designed to utilize light-emitting diodes (LEDs) as their primary light source, distinguishing them from conventional types of lighting. This technology offers significant advantages such as energy efficiency, longer lifespan, and reduced heat output when compared to traditional incandescent or halogen fixtures, which are based on older technologies like tungsten lamps.

While halogen fixtures and incandescent fixtures use tungsten lamps that produce light through heating a metal filament, LED fixtures leverage a completely different mechanism that converts electrical energy directly into light. This not only allows for brighter output with lower power consumption but also provides greater color versatility and options, including color-changing capabilities.

Fluorescent fixtures, on the other hand, work on a different principle involving gas and phosphorescent coatings. They do not utilize LED technology. Therefore, LED fixtures stand out when considering classes of lighting that use LED light sources specifically.
