How LED vs Incandescent Bulbs Make Light (and Heat)

How do LED and incandescent bulbs make light so differently? This clear explainer shows why old bulbs heat a tungsten wire until it glows (blackbody radiation) while LEDs skip the heat and turn electricity straight into photons (electroluminescence). See exactly how white LEDs use a blue chip and phosphor, what’s inside a screw‑in LED bulb, and why a 9 W LED can match a 60 W incandescent. We’ll compare lumens, watts, color temperature, CRI, dimming, and lifetime, plus the real energy savings you’ll see at home.
