Does anybody have any experience using Solartube (Tubular Daylighting
System) in EQuest? On Equest 3-61e, I was able to pick Tubular
Daylighting system, but software crashed all the time. Now I got Equest
3-63. It seems to be more stable than previous version. Does this
tubular daylighting system actually dim artificial lighting according to
accommodate foot candle set point inside of room? Did anybody
experienced a problem with tubular daylighting system?
