Types of bulbs
There are several types of light bulbs, each with unique features and uses. Here's a breakdown of the main ones:
💡 1. Incandescent Bulbs
- **How they work:** Electric current heats a filament until it glows.
- **Pros:** Cheap, warm light, dimmable.
- **Cons:** Inefficient, short lifespan, mostly phased out.
- **Use:** Older homes, decorative fixtures.
💡 2. Halogen Bulbs**
- **How they work:** Similar to incandescent but filled with halogen gas for higher efficiency.
- **Pros:** Brighter, more efficient than incandescents, dimmable.
- **Cons:** Hot to the touch, shorter lifespan than LED.
- **Use:** Headlights, spotlights, under-cabinet lighting.
💡 3. CFL (Compact Fluorescent Lamps)**
- **How they work:** Electric current excites gas inside the bulb, producing UV light that fluoresces.
- **Pros:** More efficient than incandescent, lasts longer.
- **Cons:** Contains mercury, takes time to warm up, not always dimmable.
- **Use:** General lighting, offices, energy-saving retrofits.
💡 4. LED (Light Emitting Diode)
- How they work: Electrons pass through a semiconductor, emitting light.
- Pros: Highly efficient, long-lasting, cool to the touch, dimmable, available in many colors and shapes.
- Cons: Higher upfront cost (but dropping fast).
- Use: Everywhere homes, offices, outdoor, smart lighting.
💡 5. Fluorescent Tubes**
- **How they work:** Similar to CFLs, but in long tubes.
- **Pros:** Good for large spaces, energy-efficient.
- **Cons:** Bulky, contains mercury.
- **Use:** Schools, offices, garages, warehouses.
💡 6. Smart Bulbs**
- **Type:** Usually LED-based.
- **Pros:** Controlled via smartphone, voice assistant, programmable, color-changing.
- **Cons:** More expensive, requires a hub or app.
- **Use:** Home automation, mood lighting.
