In general, a lamp uses less watt (power), but actually depends on the power of the lamps in question. For example, if you have a table lamp with two 100W lamps, it is obvious that it uses less power than a ceiling lamp with a 100W lamp.

Yes, you can replace fluorescent tubes with LED tubes or LED built-in devices. If you are not ready to replace the fluorescent device and you simply want to replace bulbs, you can use plug-and-play, direct wire or hybrid LED tubes.

LED lamps require much less power than CFL or incandescent lamps, so LED lamps are more energy-efficient and long-lasting than other types of lamps.

True, fluorescent lighting reduces the useful life of the lamps, but the lamps are designed to be lit up to seven times a day, without any effect on your life.

It's safe to leave a light on all night when people can be confused when they wake up. Low-energy lamps burn the equivalent of a 20-watt lamp.
