Ever wondered which is the brightest sun tunnel?
What makes the brightest sun tunnel all comes down to physics; forget the marketing waffle. To get the most daylight down in to the room below, from a clear dome on the roof, via a shiny tube, you need the most reflective material possible. Which is where Solatube sun tunnels win hands down,
every time. That's because only Solatube uses 99.7% reflective tubing, whereas everyone else uses 98% reflective. It may not sound like a big difference but consider this:
*Each time light bounces it loses either 2% of its light with 98% material, or just 0.3% with 99.7% tubing
* So, over an average tube run of say 10 bounces 98% reflective tubing loses a massive 20%
of the light
* 99.7% reflective Solatubes lose just 3% over the same tube
run
* That's a BIG difference
This means that you need a much larger diameter system to deliver the same amount of light as a smaller Solatube.
Ultimately, the Solatube sun tunnel is the brightest system available, and delivers more light than any other. This video demonstrates, in a very simple, non-scientific way the significant difference between, the Solatube sun tunnel and other sun tunnel systems.
