LED bulb is capable of converting 80% of the electrical energy used into light energy. The left over 20% electrical energy is lost as heat energy. Incandescent light bulbs only convert twenty% of the electrical energy used into actual light energy, which means that a staggering eighty% of electrical energy is lost as heat energy. When you compare the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal choice of light bulb is quite understood.

Major disadvantages of using LED lights

The primary limitation is the current high price of LED light bulbs. Even though the price of LED lights in South Africa is steadily decreasing, replacing a 100W incandescent light bulb with a LED substitute can cost about 5000 Rs.

For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs a lot more than make up for the high starting price.
