These new skylight tubes transmit light so efficiently, that on a clear moonlit night, it glows indoors. Natural light makes most things look better indoors. In the kitchen, foods look more appetizing than under bulbs. The acrylic rooftop dome and diffuser block nearly all of the furniture fading ultraviolet rays. A bathroom or dressing area is another excellent location for a skylight tube kit.
Some models now have optional ceiling vent kits to light and vent the bathroom with one unit.
The trim ring around the decorative ceiling light diffuser is also an air inlet vent which is attached to a flexible duct. This duct branches off to the side of the skylight tube inside the attic. The fan uses a GFCI-protected circuit. Since it is located well up inside the duct near the roof, it operates quietly. If you surf the Internet or read home magazines, it seems like everyone is selling skylight tube kits.
