OSRAM LINEARlight LM01A-S1 – “Super Red” rigid LED module 633 nm, 10 V, 4 W (32 LEDs), cut every 4 LEDs
The OSRAM LINEARlight LM01A-S1 is a rigid Super Red LED module (peak wavelength ≈ 633 nm) designed for contour, signaling, and accent lighting applications where intense, homogeneous, and reliable red light is required. Each board integrates 32 LEDs with a total power consumption of 4 W at 10 V DC (typical current ≈ 0.4 A), a wide 120° beam angle , and cut-off points every 4 LEDs to adjust the length without compromising functionality. Its narrow form factor of 448 × 10 × 4 mm and Ø 4 mm mounting holes facilitate quick installation using standard screws or hardware.
This module is perfectly suited to OSRAM OPTOTRONIC 10–10.5 V power supplies and connects exclusively in parallel (multiple boards can be connected in parallel within the converter's range). It is PWM dimmable on the secondary side using compatible OT DIM controllers , simplifying integration into projects with intensity control. Furthermore, it supports OP 4×1 (20°) snap-on optics to concentrate the beam when greater spot illumination is required.

Frequently Asked Questions
-
How is it fed? With 10–10.5 V DC from a constant-voltage source (e.g. OPTOTRONIC 10.5 V). Size the power as number of plates × 4 W + margin.
-
Can I cut the board? Yes, every 4 LEDs (minimum module 56 × 10 mm). The sections retain their functionality.
-
Can it be dimmed? Yes, by PWM on the secondary side with an OSRAM OT DIM or another compatible 10V PWM dimmer.
-
How do I connect multiple boards? Only in parallel , respecting the total current and cable cross-sections.
-
Is there optics to narrow the beam? Yes, the OP 4×1 reduces the angle from 120° to ~20° in color.
Installation Notes
- Respect polarity and parallel wiring; do not connect in series.
- Fix using the Ø 4 mm holes of the PCB or compatible hardware; avoid stress on soldering.
- For dimming, install the PWM dimmer (OT DIM) between the 10–10.5 V source and the boards.
- Maintain the temperature of point T c within the manufacturer's limits to maximize service life.
