The Cascade38 series is a round acrylic LED lighting tube with a 1.50" diameter manufactured in the USA. It features a slot that allows an aluminum LED mounting plate to slide in, acting as a physical carrier and heat sink for the LED strip.

These LED tubes are similar from Smokies38, crafted from high-quality, shatter-resistant acrylic that is designed to withstand the elements and are safe to use in outdoor applications. When unlit, the tubes appear as a solid white color, but they take on the LED's color when illuminated, creating a visually striking effect, especially when combined with RGB or RGB pixel LED strips.

These LED diffuser tubes boast robust construction, enabling them to be self-supporting for versatile installations. They can be suspended horizontally from both ends as a tube light or vertically from one end as a pendant light. They can be used as freestanding floor lamps or column lights or mounted on walls as fixtures.
