SewGlo™ is electroluminescent thread — a cold light source you sew directly into fabric with a standard sewing machine. No rigid components. No added weight. No electronics on the run. Just light, built into the textile itself.
Standard lighting has no place in a garment. SewGlo™ does. It's not a retrofit, not a clip-on, not a battery pack sewn into a pocket. It's light engineered as thread — manufacturable, washable, and built for the way clothing is actually made.
Electroluminescence is the emission of light from a phosphor material when excited by an alternating electrical current. SewGlo™ applies this at the thread scale — embedding the phosphor layer within a flexible, sewable filament that integrates directly into textile manufacturing processes.
A conductive copper core carries the alternating current that drives the light emission. It's thin, flexible, and engineered to survive the mechanical stress of sewing machine needles and fabric movement.
A zinc sulfide phosphor coating surrounds the core. When excited by AC current, the phosphor emits a continuous, even glow — no hotspots, no pixel separation, no LEDs to fail. The light is distributed along the entire length of the thread.
A protective polymer jacket makes the thread machine-sewable and fabric-safe. It protects the phosphor layer through needle penetration and movement, while maintaining flexibility for drape and comfort.
| Light Source | Electroluminescence (EL) Cold light — no heat generation, safe for direct skin contact and all fabric types |
| Installation | Standard sewing machine compatible No special equipment required. Sews like standard decorative thread |
| Power | AC inverter required (battery-operated or wired) Compact battery packs available for wearable applications. Low voltage, low current draw |
| Colors | 11 colors available White, blue, green, teal, yellow, orange, red, pink, purple, UV reactive, and custom |
| Rigid Components | Zero on the run The only hardware is the external inverter/power source — kept off the garment entirely if desired |
| Compatible Fabrics | Any standard textile Woven, knit, denim, nylon, polyester, canvas, and specialty fabrics |
| Minimum Order | Contact for wholesale pricing Available in bulk spools for production runs |
Embroidered glow lines, illuminated panels, and light-up accents integrated directly into costume construction. No battery packs stuffed in hidden pockets.
Runway and editorial illuminated apparel where aesthetics and construction quality are non-negotiable. SewGlo™ keeps the garment as the focus, not the hardware.
High-visibility illumination sewn directly into vests, jackets, and uniforms. Active light source — not reflective — for environments where passive reflectivity isn't enough.
E-textile developers and smart apparel manufacturers use SewGlo™ as the illumination layer in integrated systems — paired with conductive threads, sensors, and microcontrollers.
If your project needs more than illuminated thread — flexible EL profiles, architectural LED, or fiber optic cable — the full product line lives at Ellumiglow.com. One source for lighting technology that standard suppliers don't carry.
SewGlo™ is available in production-quantity spools for manufacturers, fashion labels, theatrical costume houses, and safety apparel producers. We work directly with brands to spec the right color, quantity, and power system for the application.
