Our Holston74 series is a 2.91" x 2.91" section large plastic square tube. This extruded plastic square tubing is made of strong polycarbonate and is available in frosted white. We can also supply this as a smoky black LED diffuser tube on request. This square LED Linear pendant channel can be used for event lighting, table lights and stage lighting.

The acrylic square tube appears as a solid white or black when they are unlit, and take on the LED color when illuminated. This is particularly effective when combined with RGBW LED lighting or RGB pixel LED strip for stunning visual effects and the square tubes can be installed side-by-side to create a wall with multiple columns of lighting effects.

These square plastic tubes are strong enough to be self-supporting, which allows for many imaginative installations such as a horizontally suspended tube light (from each end) or a vertical pendant light (from one end), as a floor standing column or pillar light, as a square LED ceiling light, or simply as a wall mounted fixture. The large size of these plastic square tubes is particularly effective for a feature lighting in larger spaces such as theater halls and outdoors.
