H-20A-COB
The H-20A-COB is a sewing machine lamp with a single COB LED, drawing 3W and designed for use on 110V or 220V supplies. It delivers a broad, even pool of light from a single emitter, which reduces glare and shadow on the needle plate. The COB design is ideal for consistent illumination across the stitching area, especially on dark or textured fabrics where a uniform light field improves visibility. The lamp is built for industrial sewing machines and fits standard mounting points without modification.

Why Buyers Choose This Model
Key Benefits
- Single COB LED creates a smooth, even light field without hotspots or dark spots
- 3W power draw keeps energy cost low across large machine fleets
- 110V or 220V operation means one model covers both major voltage standards
- No moving parts in the light source—no dimming knob to jam or fail
- Compact head design fits under tight machine heads and avoids interference with handwheel or presser foot
- Even light distribution reduces eye strain during long stitching sessions
Problems It Solves
- Multiple small LEDs create uneven lighting with bright spots and dark zones, which the COB’s single emitter avoids
- Knob dimmers fail in oily or dusty environments; the H-20A-COB has no mechanical adjustment
- Factories using separate 110V and 220V lamps face higher inventory and ordering complexity
- Overhead lighting often casts shadows from the operator’s hands; a machine-mounted COB lamp puts light where it’s needed
- Standard LED arrays can cause glare on reflective or dark fabrics; the COB’s soft spread reduces this
Who It Is For
- Garment factory maintenance managers replacing lamps across a mixed-voltage floor
- Sewing machine dealers installing lights at point of sale or service
- Machine builders specifying a standard light for OEM integration
- Importers sourcing a single model for markets using 110V or 220V
Where It Is Used
- Industrial sewing lines working on dark or black fabric where shadowing from multiple LEDs causes visibility issues
- Topstitching and embroidery stations requiring a consistent, shadow-free light field
- Factories with mixed 110V and 220V machines across the same floor or building
- Maintenance teams replacing bulbs in high-volume lines where reliability is critical
- Machine builders integrating a low-profile, high-visibility light as an OEM fitment
Technical Features
- Single COB LED emitter
- Input voltage of 110V or 220V
- 3W power consumption
- Fixed brightness output
- Compact lamp head with standard mounting
- No dimming mechanism
Materials
- COB LED chip on a high-conductivity thermal base
- Moulded plastic lamp head and housing
- Standard mounting bracket with screw holes for machine head attachment
Quality Control
- Every lamp receives a 2-hour high-voltage test before it leaves the facility
- LED chips are sourced from world-known brands rather than unbranded stock
- Visual check of the lamp head, cable, and mounting bracket before packing
- Input voltage compatibility verified on assembled units
Customisation Options
- OEM logo on the lamp head or housing
- Cable length and plug type to suit the destination market
- Own-brand retail or bulk packaging
- Mounting bracket variants for specific machine heads
How To Use It
- Mount the lamp on the machine head using the standard screw holes
- Position the lamp so the light covers the needle plate and presser foot area
- Ensure the lamp head does not interfere with the handwheel or thread path
- Use only on machines with 110V or 220V supply—verify voltage before connection
- Wipe the lens with a dry cloth to maintain light output; avoid abrasive cleaners

How It Compares
| H-20A 20 LED SMD lamp | The H-20A-COB uses a single COB LED for a softer, more even light field. The SMD version has 20 discrete LEDs, which can create hotspots and uneven illumination. The COB is better for dark fabrics and long-term visibility. |
|---|---|
| H-36D 36 SMD LED lamp | The H-20A-COB has a single COB emitter for a broad, even light. The H-36D uses 36 SMD LEDs with touch dimming, which gives higher peak brightness but more directional output. The COB is better for consistent illumination without adjustment. |
| Overhead factory lighting | A machine-mounted COB lamp delivers light directly to the needle plate, where overhead lighting cannot reach. It uses less than 10% of the power of a typical overhead fixture. |
Questions About This Product
Can the H-20A-COB run on both 110V and 220V
Yes. The lamp is designed for either 110V or 220V supply. No switch or adapter is needed.
What is the difference between the H-20A-COB and the H-20A SMD lamp
The H-20A-COB uses a single COB LED for a smooth, even light field. The H-20A uses 20 discrete SMD LEDs, which can create uneven lighting with bright spots.
How much power does it draw
3W.
Is the brightness adjustable
No. The H-20A-COB has a fixed brightness output.
Can we have the lamp with our own logo and packaging
Yes. We produce OEM versions with your logo on the lamp head and your own packaging.
What certification does the lamp carry
Please ask us for the current certification documents for your market and we will send what applies to this model.
