Question

What is the difference between incandescent and LED bulbs?

Answer 1

Differences between incandescent and LED bulbs are given below:

Incandescent	LED bulbs
1. When an electric current heats a tungsten filament wire, it glows, or incandesces, and produces light.	1. When a voltage is applied to negatively charged semiconductors, light-emitting diodes (LEDs) produce light.
2. Incandescent bulbs come in a variety of colour temperatures. Soft White (approximately $2700\mathrm{K}–3000\mathrm{K}$), Cool White $(3500\mathrm{K}–4100\mathrm{K})$, and Daylight $(5000\mathrm{K}–6500\mathrm{K})$ are the three primary options for consumers.	2. LEDs are available in a variety of colour temperatures ranging from $2200\mathrm{K}$ to $6000\mathrm{K}$ (from "warm" yellow to light or "cool" blue).
3. When an incandescent light bulb reaches the end of its useful life, it does not generally flicker or cycle on and off. Rather, incandescent light emits less light before completely failing at the end of its useful life.	3. LEDs are ideal for turning on and off on purpose because they respond almost instantly (there is no warm up or cool down period). They produce constant light with no flicker.
