When transmitting light two important considerations are Light transmission and Diffusion. When a clear material is used, direct light is allowed with maximum light transmission but introducing glare (spots of intense bright spots and shadows), hence light needs to be diffused for uniform transmission.Rigid And Flexible Light Tubes
A rigid tube is used where there are no obstructions and light is made to pass vertically from the roof to the diffuser. The system is ideal when you want access to direct light with high intensity.
A flexible light tube brings in the flexibility to mold the light pipe in case of obstructions. This can slightly reduce the light intensity compared to a rigid tube. This works well in case of retrofit buildings.
Benefits Of Using Tubular Daylighting Devices
Access to natural light – improves the wellbeing of the occupants
Affordable with very less maintenance
Green and environment-friendly
Reduced Energy costs over the long-term
To summarize: Before considering going for tubular daylighting, understand the how tubular skylights are better compared to other devices. Does it provide the lighting to suit your needs? Look at what type of tubular daylighting to use. Consider a quality provider who meets your requirements.
