I want to know the answer to the following question:
What percentage of energy does a standard light bulb actually convert to visible light?
All the background I'm provided with is that "Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%.". Is that enough to answer the question?
Answer: yes
