💡 FAQ - Light Bulbs

🔹 What are the main types of consumer light bulbs?

The four most common types are:

1. 1.Incandescent – Traditional bulbs, inexpensive but inefficient. 

2. 2.LED (Light Emitting Diode) – Very energy-efficient and long-lasting. 

3. 3.CFL (Compact Fluorescent Lamp) – More efficient than incandescent but contains small amounts of mercury. 

4. 4.Halogen – A type of incandescent that is slightly more efficient and brighter. 

🔹 What does “lumens” mean?

Lumens measure brightness. The higher the lumens, the brighter the bulb. Wattage measures power consumption, not brightness.

🔹 What is color temperature (Kelvin)?

Color temperature affects the appearance of light:

• •2700K–3000K: Warm white (yellowish - mimics incandescent bulbs) 

• •3500K–4100K: Cool white (neutral) 

• •5000K–6500K: Daylight (bluish white) 

🔹 Are all bulbs dimmable?

No. Not all bulbs are dimmable—check packaging or product specs. Dimmable LEDs require an LED compatible socket and dimmer switch.

🔹 How do I choose the right bulb base?

Common base types include:

• •E26 (standard screw base) – most common in U.S. homes 

• •E12 (candelabra) – used in chandeliers and decorative fixtures 

• •E14 (candelabra) – European base 

• •GU10 / MR16 – often used in spotlights or track lighting 

🔄 Comparison: Incandescent vs. LED Bulbs

✅ Summary:

• •LEDs are the best choice for most applications due to energy savings, long lifespan, and cooler operation. 

• •Incandescents may still be preferred for certain decorative or specialty lighting but are being phased out in many regions.
