You may want to consider using warm, ambient lighting to create a cosy and inviting atmosphere in an Irish pub. This can be achieved through the use of wall sconces, pendant lights and table lamps. You can also use dimmer switches to adjust the lighting levels depending on the time of day or the desired ambiance. Additionally, consider incorporating traditional Irish elements into the lighting design. Traditional lighting in pubs often incorporate natural materials such as wood and copper. Some examples of traditional Irish pub lighting options include:

Lanterns: Lanterns made of glass or metal can be hung from the ceiling or placed on tables for a warm and inviting ambiance.

Wall sconces: Wall sconces made of brass or copper can add a traditional touch to an Irish pub.

Chandeliers: Wrought iron chandeliers can add a rustic touch to the space.

Celtic knotwork lamps: Intricate knotwork designs which are a traditional Irish decorative element.

Candles: Candlelight can be used to create a warm, inviting atmosphere in an Irish pub and can be placed on tables or in lanterns.

These lighting options can be used to create a warm and inviting atmosphere in an Irish pub and help bring out a traditional Irish feel to your Irish pub or restauarant.
