Question

Once upon a long time ago, we only used little incandescent light bulbs to show if something was turned on or not and big incandescent light bulbs to light up rooms and as car headlights.
why we don’t use them so much anymore.

Answer 1

as we know that we are more advanced from before so we do not use this types of bulbs anymore because this types of bulbs uses a large amount of electricity and gives a very little light and now for led's led uses a very little amount of electricity to work and gives us a large amount of lights in return. And another major point of it is that it is so high cost but led's are so low costs.and a longer life.

hope it helps.
