Question
Which glows brighter?
- Incandescent bulb
- Halogen bulb
- CFL
- All of them have same price
Hint:
Bulbs used in functions are halogens
The correct answer is: Halogen bulb
- Halogen bulbs have a fragile quartz envelope and brittle filament wire. Because they operate at higher temperatures, halogen bulbs have higher color temperatures and produce brighter light than incandescent bulbs.
