CoeLux Long Sky (AXLS) systems come in two versions with skylight openings that measure approximately 1' X 4' in an approximately 2' x 4' frame using a specialized CoeLux mounting system. They can be used individually or aligned in runs to form a hallway of light delivering more depth perception.&nbsp;<br><br>AXLS-Ice produces a 45-degree beam and a sliver of light in the opposite direction. This feature makes the sun visible from various angles, which is ideal for spaces requiring more lively light.
