The term "kuthuvilaku" refers to a traditional oil lamp used in South India, particularly in the Tamil culture. In other languages and regions, it may be known as "nilavilakku" in Malayalam, "diya" in Hindi, "deepam" in Telugu, and "vilakku" in Kannada. These lamps hold cultural and religious significance and are often used during special occasions, prayers, and festivals.

The "kuthuvilaku," also known as "nilavilakku," is a traditional oil lamp commonly used in South India, especially in Tamil Nadu and Kerala. It typically consists of a brass or bronze base with an elongated stem and multiple spouts for wicks. These lamps are often adorned with intricate designs and are considered auspicious in Hindu culture.

The kuthuvilaku holds symbolic significance, representing the dispelling of darkness and the spreading of light, both literally and metaphorically. It is commonly lit during religious ceremonies, prayers, and festivals, signifying the presence of the divine and the triumph of good over evil.

During festive occasions such as Diwali, Karthigai Deepam, and other celebrations, families and communities light kuthuvilakus to create a warm and welcoming atmosphere. The gentle glow from these lamps adds a sense of serenity and spirituality to the surroundings.

The practice of lighting kuthuvilakus is deeply rooted in tradition and is often passed down through generations as a cherished custom. The flickering flames of the lamp hold cultural, religious, and social significance, symbolizing hope, positivity, and the celebration of life. There are several types of kuthuvilakus, each with its own unique design and purpose. Here are a few common types:

Thookku Vilakku: This type of kuthuvilaku is suspended from a height using chains or ropes. It is often hung in temples or outdoor spaces during festivals and religious ceremonies.

Standing Vilakku: This is a traditional floor-standing oil lamp, usually made of brass or bronze, with an ornate stem and multiple spouts for wicks. It is a common household item and is used during daily prayers and special occasions.

Hanging Vilakku: Similar to the thookku vilakku, this type is designed to be hung from the ceiling or a support structure. It is often used to decorate homes and temples during festive occasions.

Kamatchi Vilakku: This is a special type of kuthuvilaku featuring a design that represents the goddess Kamatchi. It is considered highly auspicious and is often used in temples and during religious ceremonies.
