How Bright Is the Light From A Tubular Skylight?
Natural Light Tubular Skylights illuminate the equivalent of up to 300 to 1,450 watts of incandescent lighting varying on the model installed (see chart below), but without the heat gain of traditional lighting. Additionally, Natural Light Tubular Skylights filter out 99% of the harmful UV rays that fade furniture and carpeting. And because they operate using free solar power, Natural Light Tubular Skylights are energy efficient and will help reduce your electric bills!

Natural Light Tubular Skylights Are Engineered to be the Best!
The main component of the Natural Light Tubular Skylight is a super reflective, mirror-like light pipe with a 98% reflectivity rate. The entire length of the pipe’s interior is coated with the reflective surface that is responsible for bouncing sunlight several times as it travels through the tube. This coating is called Miro-Silver.
Miro-Silver versus Multi-layer Polymeric Film (MPF)
Many other tubular skylights use a much thinner, less reflective material called Multi-layer Polymeric Film (MPF). A series of tests were conducted comparing the Miro-Silver® light pipe to the more standard Multi-layer Polymeric Film (MPF). The test’s purpose was to measure the amount of light reflected at different times of the day – particularly when the sun’s angle is low and light is really needed (early morning and late afternoon).
Light reflection measurements were taken with the sun’s angle at 13.8 and 40 degrees on a 10 foot long x 12″ diameter tube. The test results prove that Natural Light’s Miro-Silver light pipes transmit much more light between 13.8 and 40 degrees than the standard Multi-layer Polymeric Film.
