Solatube Highest Performance Guarantee
All day long. All year long.

Highest Performance Guarantee
Thank you for purchasing a Solatube Daylighting System featuring breakthrough technology for higher performance. Solatube International, Inc. guarantees that when using the Natural Effect Lens**, the 160 DS and 290 DS Daylighting Systems deliver more Average Daily Light on an Annual Basis (as determined by the methodology set forth below) than other passive tubular daylighting devices having the same "L over D ratio" (as defined below) that are widely commercially available on the market at the time of your purchase. We are totally confident that no other product offers the total annual performance of a Solatube product. We will give you YOUR MONEY BACK (retail purchase price) if you find such a product.

Limitations on Guarantee

Offer excludes new products manufactured by Solatube International, Inc. The guarantee excludes all other products, except Solatube 160 DS and 290 DS products, manufactured by Solatube International, Inc. Offer expires one year from product purchase date.

Methodology for Determining Average Daily Light on an Annual Basis (ADLAB)
The ADLAB is determined by measuring the light output of a system at each hour during daylight hours on the 21st day of March, June, September and December. To determine the ADLAB, these measurements are then added together and divided by the total number of measurements taken. To compare ADLABs, the systems compared must have the same ratio of Length of daylighting tube divided by the Diameter of the tube opening. This is called the "L over D ratio." Testing must be completed by a certified testing agency.
