Light emitting diodes are used to emit light! They can be used in flashlights, car headlights and traffic signals. Originally they were used for digital displays on clocks and calculators. There are many used for simple indicators such as on flash drives and under status lights in computer equipment. If you have a CAPS lock key light on your keyboard, it is an LED.

The use of LEDs is to save a electricity, they consume less power than a light bulb, and last longer.

LED's or `light emitting diodes' are solid state lights, meaning that they have no filament, which generate their light as power is applied to a junction which could be made up of many different materials such as gallium arsenide. Depending on the materials used, the light can be several different colors ranging from red to white and all colors between.
Many times in the epoxy shell in which the electronic junction is encapsulated, they'll add an additional `doping' compound to assist in the light producing a different or enhanced color. For instance a white LED is usually a blue LED which is `doped' to produce a white light. Over a period of time, the white LED will start to get bluish as it ages and the doping `wears out'.

1] to display a condition on a panel
2] In great quantity it can be used as a lamp or light illumination
And there many types of the same family that give out infrared. ultraviolet and many other colors just by shifting to a low or hi in the color spectrum range.
No.
lighting stuff?

LED's
LEDs come in different types based on how they’re used. The most common ones are: Miniature LEDs – Used in remote controls, indicators, toys High-Power LEDs – Bright and long-lasting, used in industrial lights RGB LEDs – Change colors, great for displays and mood lighting SMD LEDs – Found in strip lights, TVs, and flat panels COB LEDs – Give strong, focused light, perfect for spotlights and studio setups Bi-color & Tri-color LEDs – Offer multiple colors in one unit If you’re looking for professional lighting—like for film, photo, or ad shoots—brands like Godox and Aputure offer solid options. But for serious, high-performance studio lighting, Ilfords Cine Lighting Equipment (available on Pepagora) brings lighting tools that are built for creators. Whether you’re an indie filmmaker or running a small production team, they understand your struggle for quality lighting without blowing the budget. It’s made for creators, by people who get it.
Maybe it's used more? I don't Know.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Halogen Bulbs
Yes, LEDs are dimmable.
LEDs are used in traffic lights, on computer lights, car lights and indicators. You can also purchase LED flashlights and torches. Can be used in small devices for a variety of uses.
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.
