What this review found
The OSRAM Night Breaker LED Smart ECE H11, model 64211DWNBSM-ECE, recorded 1,192 lux at 50V, 1,568 lux at 50R and 1,670 lux at EMAX. The measured chip/emitter thickness was 2.446 mm. The emitter-area temperature was 74.3°C after 20 minutes, and operating noise was 48.9 dBA at 3.5 cm.
The nine-point record shows a stronger centre and 50R result than the outer 25R value. The 25L and 50L readings were 366.6 lux and 516.4 lux. B50L was 32 lux and is treated separately because it is glare-control-related. EMAX is a peak reference, not a complete beam rating.
Product identity and approval record
Product: OSRAM Night Breaker LED Smart ECE H11
Model reference: 64211DWNBSM-ECE
Format: H11
Recorded scope: packaging, physical construction, H11 interface, optical evidence, emitter-area temperature and operating noise.
An approval document is on file for the identified OSRAM product. The model reference is included because it is the documented product identity available for this page. No approval number or holder is inferred. The approval record and this bench evaluation are separate evidence.
R37-defined requirement: the approval record relates to the regulated light-source category and required marking. Same-setup comparison: the images and measurements shown here. Not tested under the official approval procedure: the local setup does not establish official type approval, vehicle-specific fitment or complete road performance.
Packaging and included parts
The package images document the visible presentation, included contents, external package dimensions and empty-package weight. They describe the reviewed package record only. Retail packaging and included parts can differ by market or configuration, so the images should be used as a check against the product supplied.
OSRAM H11 fitment and construction
The product overview shows the OSRAM-marked H11 body, front emitter area, mounting base, rear cooling structure and connected lead. The side, top, connector and dimension views provide physical reference points for comparing the bulb with the original lamp. They do not confirm dust-cap closure or clearance in a specific vehicle.
The emitter close-up shows the front light-source area. The adjacent external-micrometer image records a chip/emitter thickness of 2.446 mm. This is a physical reading from the photographed product. It is not an R37 regulatory dimension and does not independently determine the beam pattern.
Test method and evidence boundary
Illuminance was recorded at the defined E-Mark panel points at 3.5 m, in a 26°C room, after 30 minutes of operation. The documented optical records use 13.2 V where that condition is stated. Emitter-area temperature was recorded after 20 minutes. Operating noise was recorded at 3.5 cm. These are same-setup conditions, not the official approval procedure.
The white-wall photograph shows the visible beam on the test surface. The rainbow map shows relative hotspot distribution. The E-Mark composite supplies numerical readings at defined positions. Together they describe the recorded setup. They do not establish a complete angular scan, vehicle fitment, service life or approval conclusion.
White-wall beam pattern
The white-wall photograph records the visible low-beam spread, transition and brighter areas produced by the OSRAM unit in the test optic. It is useful for inspecting shape alongside the panel readings. Aim, reflector geometry, camera exposure and vehicle headlamp design can change the image in use, so it is treated as visual evidence rather than a full road assessment.
Rainbow map and hotspot distribution
The rainbow map shows the relative colour distribution and the stronger hotspot areas in the recorded beam. It adds spatial context to the white-wall photograph and helps explain why individual panel readings should be read by location. Its colour scale is not a substitute for lux and does not independently establish glare control.
E-Mark panel and complete nine-point table
The composite records nine illuminance values in lux. Keeping all points visible makes the distribution easier to inspect than a single peak headline.
| Point | Measured illuminance | Reading area |
|---|---|---|
| 25L | 366.6 lux | Left-side point |
| 50L | 516.4 lux | Left-side point |
| B50L | 32 lux | Glare-control-related point |
| 50V | 1,192 lux | Centre point |
| 25V | 1,022 lux | Centre point |
| 75R | 1,037 lux | Right-side point |
| 50R | 1,568 lux | Right-side point |
| 25R | 361.8 lux | Right-side point |
| EMAX | 1,670 lux | Peak reference |
The left-side readings were 366.6 lux at 25L and 516.4 lux at 50L. Centre readings were 1,192 lux at 50V and 1,022 lux at 25V. Right-side readings were 1,037 lux at 75R, 1,568 lux at 50R and 361.8 lux at 25R. B50L was 32 lux and remains a glare-control-related reading. EMAX was 1,670 lux and remains a peak reference.
Temperature and operating noise
The measured emitter-area temperature was 74.3°C after 20 minutes. It describes the photographed point and operating condition. It is not ambient temperature, driver-box temperature, Tcap or a prediction of long-term service life.
Operating noise measured 48.9 dBA at 3.5 cm. This is a close-range test reference. It can differ from the sound heard in a vehicle because of enclosure, distance, installation position and surrounding noise.
Using the results and final assessment
The OSRAM record is most useful as a distribution profile. It combines a strong 50V value of 1,192 lux and 50R value of 1,568 lux with lower outer points, including 361.8 lux at 25R. The 2.446 mm measured chip/emitter thickness is a physical reference that should be read with the beam photographs, not used as a standalone performance rule.
Before installation, confirm the H11 interface and compare the base, connector, rear cooling structure, driver and dust-cap space with the intended lamp. After installation, verify seating, rotation, beam aim and glare in the actual headlamp. The documented connector does not prove fitment for every vehicle.
The OSRAM Night Breaker LED Smart ECE H11 64211DWNBSM-ECE has a documented package and construction record, 2.446 mm measured chip/emitter thickness, a complete nine-point table, 74.3°C emitter-area temperature after 20 minutes and 48.9 dBA noise at 3.5 cm. The images and values provide a practical evidence record for this product and setup. Approval markings and vehicle-specific conditions still need separate verification.
