Do Bathroom Lights Need To Be Damp-Rated? Lighting Guide

Lights purchased around the house are often damp-rated or wet-rated. Based on how much moisture is being absorbed in that room, these ratings will help determine which style and type of bulb to buy. This often raises the question, do bathroom lights need to be damp-rated?

Bathroom lights need to be damp-rated in high-moisture areas. It’s recommended that lights directly exposed to any moisture should be damp-rated. This includes bathroom lights, basement lights, and any outdoor lighting.

It’s essential to check the damp rating of the lights, especially if you’re purchasing them for your bathroom or outdoor patio. This article will explain what the damp rating means and why it’s both efficient and effective to buy damp-rated light bulbs.

Why Bathroom Lights Need To Be Damp Rated

Bathrooms light need to be damp-rated. Due to the water (hot or cold) that’s generated from the sink and shower, there’s a chance for humidity to rest upon the bulb.

Damp-rated areas include indoor pools, bathrooms, and light fixtures near the kitchen sink/stove. Although there may not be any direct contact made, there’s a chance water could get on the light bulb, which makes it damp-rated.

Answering the question above, bathroom lights don’t necessarily need to be damp-rated, but we highly encourage that you get them.

Lights away from the shower and the sink can be installed as standard lights. However, lights placed directly above a shower bathroom with no casing and damp-rated lights are the best bet.

What Does Damp Rated Mean?

Damp ratings are a rating system given to a light bulb that measures how much moisture it can absorb before faulting.

Light fixtures and ceiling fans should be marked “suitable for damp locations” or wet locations.” These safety labels are marked on the lights and fans to protect the homeowner from faulty or possibly harmful moisture buildup with the electricity.

Rooms that boast atmospheres may warrant a damp rating, such as a bathroom or kitchen space.

According to home electrical, anywhere with light fixtures exposed to water, rain, or heavy storms will often have a wet rating. Here is an example of a light purchase with a damp rating.

This is important to pay attention to, especially if you’re purchasing light bulbs for areas with high moisture.

This article will show you the difference between a damp rated and a non-damp rated light to help you with your buying decisions as a homeowner.

Are Bathrooms Considered A Damp Location?

Yes. Any area directly affected by moisture or any heavy condensation is considered damp. The best way to understand damp locations is essentially any small area or room where moisture can build up over some time.

For example, a bathroom or a sauna room can build up moisture. The bathtub or the shower will build up moisture that typically rises and settles on the light bulbs. If the lights can handle the moisture, they will break or short out.

Simply by ensuring the light is damp-rated, you will save yourself time fixing lights, but you will also save your wallet from spending money on light bulbs.
