Myth or Fact #8: "LED bulbs don't get hot"

MYTHTHE VERDICT
// WHAT YOU WILL LEARN

MYTH: the driver and heatsink get warm, just far cooler than an old bulb.

// LESSON NOTES

"LED bulbs don't get hot." Myth or fact? 💡🔥

❌ MYTH!

1️⃣ WHERE THE POWER GOES: a good LED bulb turns only about 30–45 % of its power into light. Over half still becomes heat — mostly in the base, where the driver and the heatsink are. The beam feels cool because LEDs send almost no infrared forward.

2️⃣ HOW HOT: the base of an LED bulb can reach about 60 °C (140 °F) — too hot to hold! An old 60 W bulb's glass runs even hotter: over 120 °C (250 °F).

3️⃣ HEAT KILLS LEDs: the hotter they run, the shorter they live. Use open fittings — or, for closed glass fittings, buy bulbs marked "suitable for enclosed fixtures".

Cooler, not cold!
