OSRAM LINEARlight LM01A-T2 - Green Rigid LED Module 525 nm (10 V, 32 LEDs)
The OSRAM LINEARlight LM01A-T2 is a rigid green (525 nm) LED strip/module designed for signage, contour lighting, and edge lighting applications. Its rigid circuit board integrates 32 LEDs with a 120° beam angle and offers a total power of 4 W at 10 V DC , with a current of 0.4 A per module. The modular design allows for segmentation into 4-LED units (every 56 mm) without loss of functionality. Connection is exclusively in parallel , and a maximum of 3 modules per branch is recommended.
Optimized for OSRAM OPTOTRONIC power supplies, it allows PWM dimming using compatible control interfaces (e.g., OT DIM) installed on the secondary side of the power supply. It features 4 mm mounting holes for direct attachment and supports accessory optics that narrow the beam, facilitating everything from continuous lines of light to accent lighting. The operating temperature range of the green version is -30–75 °C , and the module does not have a factory-applied conformal coating, so it must be properly housed/protected in humid or dusty environments.

Frequently Asked Questions
Can the strip be cut?
Yes. The module allows cutting into 4 LED segments (56 mm) marked on the PCB.
How do I connect it?
Parallel only . From the same feeder point, a maximum of 3 modules per branch is recommended.
Can the brightness be adjusted?
Yes, by means of PWM on the secondary side using OSRAM OT DIM interfaces with OPTOTRONIC constant voltage sources.
Is it suitable for outdoor use?
The module does not have a conformal coating. If moisture/dust is present, it must be mounted in a luminaire/housing with adequate protection or have a specific PCB coating applied according to the manufacturer's recommendations.
Are there optics to narrow the beam?
Yes, there are accessory optics that can reduce the angle from 120° to ~20° in color modules.
Installation and connection
- Respect polarity ( 10 V ± on designated pads) and avoid mechanical stress on the PCB.
- Use screws with insulating washers to protect tracks.
- If the driver can exceed 2 A, incorporate fast-blow fuses into the design.
- For humid environments, complete cuts and wiring before applying a conformal coating suitable for LED/PCB.
Compatibility and accessories
-
Drivers: OSRAM OPTOTRONIC constant voltage (~10.5V recommended by the manufacturer).
-
Control: OSRAM OT DIM (0–10 V) with PWM output on the secondary side.
-
Optics: OS-OP 4×1-20 family for narrowing the beam (color).
-
Connectivity: feeders and connectors specifically for LINEARlight.
