The T60x185W is a tall tubular decorative bulb (60mm diameter × 185mm height) featuring six precision vertical pleats running the full length of its frosted glass shell. These aren't subtle surface marks — they're deep, structural folds that create alternating flat faces and recessed valleys around the tube's circumference.
The result is a bulb that produces alternating bands of bright and soft light — the flat faces glow evenly while the recessed folds create darker channels between them. This mimics the way candlelight flickers and shifts, producing a warm, hazy atmosphere that solid-wall tube bulbs simply cannot achieve.
Why exactly six pleats? The number is carefully chosen:
A common problem with tube bulbs is internal shadowing — a single straight filament lights one side while leaving the opposite side dim. The T60x185W solves this with twin 300mm filaments that are tightly wound around each other in a double helix configuration.
This twisted-pair design ensures:
The tall, slim profile makes it a natural fit for table lamp fixtures where the bulb is partially or fully visible. The pleated texture adds character to even the simplest lamp base, transforming a basic fixture into a vintage statement piece. At 460lm, it provides genuine reading-level ambient light.
In upward-facing chandelier arms, the vertical pleats are fully visible from below — each bulb becomes a faceted column of warm light. Multiple T60x185W bulbs in a single fixture create a cathedral-like effect with their combined pleat patterns.
Wall sconces that expose the bulb benefit enormously from the pleated texture. The alternating bright-dark pattern projected on the wall behind creates depth and atmosphere that smooth bulbs cannot. Dimmed to 30%, it serves as a perfect night-time corridor guide light.
The tubular form and faceted texture align with industrial design language — the pleats reference corrugated metal, factory piping, and machine-age aesthetics while the warm frosted glow softens the industrial edge. It bridges raw and refined.
Our product range includes many globe (G-series) decorative bulbs. The T60 tube serves different needs:
Available at MOQ 1000 pieces. The six-pleat frosted glass uses a specialized tubular mold. Customization options include color temperature (2200K–3000K), glass finish (standard frost, deep frost, or semi-clear), and pleat depth (standard or shallow). Lead time 15–30 days. Full CE, RoHS, UL certification.
The pleated structure actually increases rigidity compared to a smooth cylinder — the folds act like structural ribs. Combined with thickened hard-material glass, the T60x185W is more resistant to shipping stress than it appears. We use individual tube-specific protective packaging.
Yes — it operates in any orientation. However, the visual effect is designed for vertical mounting (pleats running up-down). Horizontal mounting still works technically but the pleat shadows project differently and the aesthetic impact is reduced.
Standard T30 tubes have smooth clear glass and visible straight filaments — a classic Edison aesthetic. The T60x185W is wider (60mm vs 30mm), frosted (soft diffusion vs clear), and pleated (textured vs smooth). It's a more substantial, more atmospheric product that creates ambiance rather than simply displaying filaments.
Yes — we offer standard depth (pronounced pleats with strong light-dark alternation) and shallow depth (subtle texture with gentler gradation). Standard is recommended for maximum atmospheric impact; shallow works for settings where subtlety is preferred.
A single 600mm filament would be fragile and prone to sagging. Two 300mm filaments wound together provide the same total luminous length with better structural support, more even light distribution, and built-in redundancy. If one filament developed an issue, the other would continue operating.
