Can I use a lower-wattage bulb?

Yes, you can use a lower-wattage bulb in your home. However, what you need to keep in mind is that a lower-wattage bulb will not provide you with the same level of brightness as it would using a higher-wattage bulb.

So if you are looking to save energy, it’s much better to use a lower-wattage bulb in the right fixture.

Can I use a 60-watt bulb in a 40-watt lamp?

Yes, you can use 60 Watt in 40 Watts light bulbs. But it’s always better if you use 60 watts bulb than 60 watts light bulb. Because if you use 60 watts in 40 watts light bulb,

it might get fit in its place, but it will get heated up more than it should. And the more the wattage of the bulb, the more it will get heated up.

Difference between 40w and 60w bulb

For one, the higher the temperature of the light produced by the lamp the more energy it consumes.  So a 60W bulb will use 60 watts.  But it might be using only 50W of power to produce its light.  

For example, a 60W bulb may use 25W to power the filament, 25W to have the lamp warm up, 10W for the ballast, and 10W to power the electronics load.  So for this example, the bulb is consuming 50W of energy.

The difference between the 40W and 60W is 10W.  This may not sound like a lot, but it could be the difference between putting your desk light and the night light on and off.  So, if you find yourself needing to save energy and you’re using a desk lamp, switch to a lower-watt bulb.
