Bamboo Tube Filament Bulb: A Segmented Amber Glass Tube That Breaks the Edison Mold

What Is the Bamboo Tube Filament Bulb?

Most vintage Edison bulbs are round, pear-shaped, or T-shaped. The Bamboo-300A uses a long tube with segmented walls that mimic bamboo joints. The shell is amber glass, and a spiral LED filament runs through the middle. The shape is the first thing people notice, and it is what makes the bulb hard to confuse with a standard filament bulb.

The bulb is sold in two lengths with the same diameter and shape: T30185 (185mm) and T30300 (300mm). The 300mm version is the one in the spec sheet below, with 5W, 300lm at 2200K, and CRI Ra>95.

Two Looks in One Bulb

The bulb has two distinct looks depending on whether it is powered:

  • Powered off: The amber bamboo glass has a warm golden tone that works as a display ornament on its own.
  • Powered on: The spiral filament glows through the glass, giving a soft retro light that is brightest along the spiral.
  • Both states: Buyers get a decorative object and a working light source from a single SKU.

Where It Works Best

Pendants and Chandeliers

The tall, narrow profile suits pendants and multi-arm chandeliers, where the long shape reads clearly from below. Several bulbs at different heights create a vertical rhythm.

Cafes, Bars and Restaurants

The warm amber tone and visible spiral suit vintage cafes and bars. The unusual shape is also a good talking point for guests and a photo subject.

Retail and Display

Shops and galleries can use the bulb as a display piece. Because it looks good unlit, it can stay on a shelf or in a window between shows.
