When it comes to choosing the right wattage for bathroom lighting, there are several factors to consider, such as the size of the bathroom, the layout, and the desired brightness level. Here are some recommendations from the search results:

• For small or medium-sized bathrooms like half-baths and powder rooms, 45-60 watts are acceptable.
• For the master or guest bathrooms, 75-100 watts is recommended.
• Larry Campbell, a licensed master electrician, suggests using a minimum of two 60-watt incandescent bulbs for bath vanities, which typically produce approximately 800 lumens.
• LED bulbs are a good choice for bathroom lighting because they are energy-efficient, long-lasting, and dont generate as much heat as incandescent bulbs.

Its worth noting that the desired brightness level can vary depending on personal preference and age. For example, staying around 100 watts can aid with vision and safety for seniors. Additionally, dimmers can be installed to provide more lighting options in terms of wattage and brightness.
