It depends on the power of the lamps, the period of operation (lighting), their number, and the consumption of the system for controlling their switching on and off. For comparison, it can be written that on average one LED 10W light bulb gives incandescent light, but with a power of 70W. We have bulbs with a power of 1W.

Dear Teodora,

Thank you for your reply. I came across this:

I was wondering if there are some more academic/scientific literature sources available on this topic.

I should also add to my question: is there a theoretical minimum limit for the amount of required syandby power for the so-called smart LED lighting systems (with dimming, etc.)? Or it could ideally become zero in the future?

Dear Aryan,

Consumption can not be zero, but if someone invented bulbs to produce and store the energy they need. And now there are such, street lighting. For a specialized search, he worked for Krasimir Velinov.

see page 29:

" DimTone lamps are controlled by an external dimmer when the lamp is in the ON mode, and there is thus no standby power consumption."

Could you explain it more?

I will read it carefully, I have not worked in this area.

I slightly divert the subject, but it's connected.

Smart technology is a great thing - everything is reglamented and regulated, cash machines are tied to the tax office, energy, gas, water, bills, production, energy quality are monitored. But - it should not have stopped the electricity. In case of an accident, even from a restaurant to have a furnace and bake pizzas, for example, they can not sell anything because the cash register has no connection to the tax office. So, in the smart technologies for certain activities should be included spare battery power.
