Ihave 2 bulbs one coverts 60% of energy to light 45% which is the most efficient and what happens to the rest of the energy

can someone me with this question asap

60% one is the most efficient one

Explanation: First one is given 60% of light energy out of 100% and second one is given 45% light energy out of 100%. Waste of first one is 40% and second one is 55% .

Then those waste energy is transfer to the heat energy.

When you touch the bulb you feel hot . Its because of heat energy. If the heat loss is less . Bulb is more efficient

that is probably false!
