can i use a bulb with lower wattage

by Ozella Deckow Published 3 years ago Updated 2 years ago

A bulb with a lower watt can safely be used in a high wattage-rated light socket as it’ll draw less electricity and produce less heat. But a bulb with a higher watt than a bulb fixture can tolerate can’t be used as it’ll pull more electricity than the fixture is designed and can cause fire threats.

As long as you don't go over the manufacturer's recommended wattage, you'll be safe. If your fixture doesn't have a wattage recommendation, the rule of thumb is to choose bulbs with 60-watts or lower.Mar 10, 2017

25W in a 20W socket is 25% oversized. so just as bad. There's a good chance that something will break, and it might be the transformer in the base of that lamp, that part is most unlikely to have 25% excess capacity.

What will happens if you put a 60 Watt in a 40 watt?

jm1 wrote: Higher wattage alone doesn't make the bulb burn out faster, but the rating partially has to do with heat/fire. For example, the fixture may only be designed to handle the heat of a 40W. Put in a 60W and the heat increases, there's not enough ventilation, and the bulb prematurely fails due to the higher heat.

Can you use 40W instead of 34W?

Usually it's fine to swap a 40W tube with a 34W tube, but some ballasts can overheat with a 34W tube installed. Check the ballast to see if it says it's rated for 34W tubes, and if it doesn't then check with the manufacturer of the ballast.

What does lower wattage mean?

Lower wattage means less heat from the bulb so the socket will last longer. Modern compact fluorescent and LED bulbs produce more light for a given wattage than an incandescent bulb, so you can more light from a lamp if you use one of them.

What is the wattage of a socket?

The watt rating on a socket is the maximum wattage (based on using an incandescent bulb) that can be used without overheating and potentially causing damage or even a fire. So a socket rated at 60W may have a 60W or lower incandescent bulb in it. However, this is rated at the actual power, not equivalent light.
