In this Flashcards Friday episode, we take the science of light bulbs out of the hardware aisle and into everyday life. Most people assume a bulb is just a bulb, but the truth is that the type you choose affects your energy bill, eye comfort, the way your rooms feel, and even the safety of your fixtures. From LEDs to incandescent filaments, from color temperature to socket fit, this episode breaks down the science behind the glow. You'll walk away with practical knowledge you can use immediately, all through the lens of curiosity and real-world physics.

1. The science behind the most common types of light bulbs - You'll explore how incandescent, halogen, CFL, and LED bulbs actually produce light, why some run hot while others stay cool, and what those differences mean for your home and energy use.
2. Why color temperature matters more than most people realize - You'll learn how warm, neutral, and cool tones affect visibility, mood, and comfort, and how to choose the right color temperature for different rooms in your home.
3. How to choose a bulb that safely fits your fixture - You'll understand why the right socket base, wattage rating, and fixture requirements matter, and how picking the correct bulb prevents overheating, flickering, or damaged lamps.
