OSRAM LM01A-W1-847 – Rigid LED module LINEARlight white 4700 K (10 V, 32 LEDs, 120°)
The OSRAM LINEARlight LM01A-W1-847 is a highly reliable, rigid LED bar with 32 diodes mounted on a PCB, providing a neutral white light of 4700 K. Designed for constant 10 V DC power supply and intended for modular installations, it can be cut into 4-LED segments (56 × 10 mm) without affecting the operation of the remaining segments. Its dimensions of 448 × 10 × 4 mm , 120° beam angle , and Ø 4 mm mounting holes facilitate quick and secure installation on profiles, guides, or mechanical supports. Optimized for OSRAM OPTOTRONIC power supplies , it is PWM-controlled with OT DIM controllers, enabling integrated dimming and control in professional applications.
Main features
-
4700K white light (code 847) with a 120° beam angle for uniform illumination.
-
32 LEDs per module; dimensions: 448 × 10 × 4 mm.
-
Segmentation: cuts allowed every 4 LEDs (56 × 10 mm segment) without loss of function.
-
Voltage: 10 V DC (operating range 10…11 V DC).
-
Typical power and current (W1-847): 3.2 W and 0.32 A. (The W2-847 variant is 4.0 W.)
-
Typical luminous flux: 29 lm.
-
Electrical connection: only in parallel ; up to 3 consecutive modules can be installed from each power point.
-
Easy assembly: Ø 4 mm fixing holes; compatible with OSRAM CONNECT connectors (OS-LM-2PIN, OS-LM-CONN).
-
Regulation: by PWM using OSRAM OT DIM controllers on the secondary side.
-
Optional optics: OSRAM OS-OP 4×1-20 system to reduce the beam to ~20° (white).
-
Serving temperature (Tc): −30…+75 °C; storage: −40…+85 °C.
Product benefits
-
Real modularity : possibility of cutting into 4 LED sections to precisely adjust the length of the project.
-
Professional integration : designed to work with OPTOTRONIC and OT DIM controllers on 10V lines.
-
Clean and reliable installation : standard 4 mm drill holes and connectivity ready; screen-printed polarity “10V +/−”.
-
Homogeneity : 120° beam that favors continuous lines of light or uniform injection in diffuse guides.
-
Scalability : parallel connection and up to 3 consecutive modules per power point to extend runs with electrical stability.
Use cases
- Contour and accent lighting in furniture, shop windows and interior architecture.
- Light injection in diffuse or transparent light guides .
- Signage, backlighting and projects with 0–10 V + PWM control via OT DIM.
Frequently Asked Questions
-
Can it be dimmed? Yes, via PWM using OSRAM OT DIM controllers on the secondary side.
-
Can I cut the bar? Yes, in units of 4 LEDs marked on the PCB; the rest of the module continues to function.
-
Is series connection allowed? No; only parallel connection for safe current sharing.
-
How many modules can I power online? Up to 3 consecutive modules from each power point.
-
Is there optics to focus the beam? Yes, the OS-OP 4×1-20 reduces the beam to ~20° in white versions.
Installation recommendations
- Use a 10V constant voltage source with protections (short circuit, overload and over temperature).
- Respect the polarity 10V +/− ; reversing it may damage the module.
- If the source can supply >2 A, protect the line with fast-blow fuses in the wiring.
- The module is supplied without conformal coating ; for environments with humidity or dust, install in a suitable enclosure or apply specific conformal varnish.
