Question

To save energy and prevent warming, I use ...................... instead of incandescent bulbs.

Answer 1

CFL (Compact fluorescent light) bulbs use less energy than incandescent bulbs (about 70% less energy). Incandescent bulbs emit a continuous spectrum of electromagnetic radiation including infrared radiation and visible light. These bulbs get hot very fast and thus, consume much energy. CFL bulbs emit only a few wavelengths of UV light which are converted into visible light and thus, they consume less energy though they take more time to warm up.

So, the correct answer is 'CFL'
