There are several types of fixtures and bulbs that are commonly used for underground light. Here are a few examples:
1.LED: LED bulbs are energy-efficient, long-lasting, and emit a bright, cool light that works well for outdoor spaces. They are also available in a variety of colors, making them a popular choice for decorative lighting.
2.Halogen: Halogen bulbs are known for their bright, warm light and are often used for accent lighting. They are less energy-efficient than LEDs, but they can provide a more intense light.
3.Fluorescent: Fluorescent bulbs are efficient and long-lasting, but they are not as bright as other types of bulbs. They work well for general lighting in underground spaces, but may not be suitable for accent lighting.
4.Fiber Optic: Fiber optic lighting systems use small, flexible fibers to transmit light from a remote source to a fixture. This type of lighting can be used for accent or decorative lighting, and is often used in water features, such as fountains and pools.
As for fixtures, there are several options available, including recessed lights, step lights, and path lights. Recessed lights are installed flush with the ground and provide a low profile lighting option. Step lights are installed into steps or retaining walls, and provide safety and accent lighting. Path lights are installed along walkways or paths, and provide directional lighting to guide people through the space.
