Hi! So It is impossible to say without knowing how long the lamp cord is. It also depends on what furniture is under the lamp: if there is a large coffee table directly under the lamp, for example, the husband is not going to be standing under the lamp!
Let the original electricity units used without energy savings be 100 units.
After the first energy saving improvement, the energy used
is 100 U - 25% of 100 U = 75U
After the second energy saving improvement, the energy used is
75U - 55% of 75 U = 33.75 U
After the third energy saving improvement, the energy used is
33.75 U - 20% of 33.75 U = 27U
Therefore, the overall percentage saving is 100U - 27U = 73U or 73%
