This is a fixed 22 mm panel-mount LED indicator lamp — the most common industrial cabinet panel size — in five colors and five voltages from 12 V DC up to 380 V AC three-phase. AD16-22DS standard form factor, sub-20 mA draw, CE-certified PC body, threaded back ring for solid panel mounting.
Product Description
This is a panel-mount LED pilot indicator lamp with a fixed 22 mm mounting cutout, the dominant size in industrial control cabinets, machine tool panels, and electrical distribution boards. The 22 mm cutout standard is widely adopted across European and Asian industrial equipment, making this lamp a drop-in replacement or upgrade for thousands of installed devices that follow the AD16-22DS form factor.
Five voltage variants (12 V DC, 24 V DC, 110 V AC, 220 V AC, 380 V AC) cover the full spectrum from low-voltage logic indication through three-phase mains; the 380 V variant is specifically intended for industrial three-phase power-on indication where many lower-voltage lamps would not survive. Five colors (red, green, blue, yellow, white) follow IEC 60073 standard convention so installations remain readable across operators and shifts.
Key Benefits
- Fixed 22 mm cutout matches industry-standard industrial cabinet panel size
- 380 V AC variant covers three-phase mains indication — most lamp categories stop at 220 V
- AD16-22DS form factor is interchangeable with the largest installed base of pilot lamps
- Built-in driver circuit — wire directly to selected voltage rail without external resistor
- Sub-20 mA per lamp lets large multi-lamp panels run on small auxiliary supplies
Key Features
The defining feature is the fixed 22 mm cutout combined with the 380 V three-phase variant availability. 22 mm is the standard cutout for industrial control cabinets across most of Europe, Latin America, and Asia, so this lamp lands as a direct replacement on existing machinery without panel modification. The 380 V variant matters because three-phase industrial systems frequently need a "line live" indicator that survives full mains exposure — cheaper indicator lamps that top out at 220 V will fail on 380 V three-phase between phases.

What's Included
- 1 x 22 mm panel-mount LED indicator lamp (per selected color and voltage variant)
Compatibility & Applications
This indicator fits any panel or enclosure with a 22 mm circular cutout, paired with a power source matching the selected variant voltage. Typical applications include:
- Industrial control cabinets and machine tool panels
- Electrical distribution boards and breaker panels
- Three-phase power line indicators (380 V variant)
- Process automation enclosures and PLC interface panels
- Replacement lamps for existing AD16-22DS installations
Not compatible with: 16 mm or 30 mm panel cutouts, voltages outside the 12/24/110/220/380 V supported set, fully submerged use, or applications requiring an audible alarm (use the buzzer indicator variant for that).

Frequently Asked Questions
Why is 22 mm the standard industrial cutout size?
22 mm became the de facto industrial cutout standard because it is large enough to accommodate the threaded mounting collar of common pilot lamps, push buttons, and selector switches with margin, but small enough to fit dense control panels with multiple devices side-by-side. AD16-22 is the most common form-factor specification building around this cutout, and is recognized by virtually every industrial OEM.
Will the 380 V variant survive on actual three-phase power?
Yes. The 380 V variant is rated for continuous duty on 380 V AC three-phase systems and is the right choice when you need to indicate the live state of a three-phase line between two phases. Do not use the 220 V variant on 380 V three-phase wiring — it will overheat and fail.
Can I replace existing pilot lamps on my equipment with this?
If your existing lamp is an AD16-22 form factor (most industrial control panels in service worldwide), this is a dimensional drop-in. Match the voltage variant to your supply and the color to your panel labeling convention. Mounting threads, depth, and projection are the same as the originals.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this 22 mm indicator compare to others in its category?
Within the 22 mm panel indicator category, the meaningful comparison points are voltage range (especially 380 V availability), color range, and form-factor compatibility. This product offers five voltages including three-phase 380 V, five colors, and standard AD16-22DS dimensions — the configuration that fits the largest installed base of industrial-cabinet applications and drives the lowest return rate within our control-component category.
