The luminaire steps back.
Life moves forward.

A deeply recessed light source draws the space in a more comfortable light. Sit, talk or read, with attention on people and objects rather than bright points overhead.

UGR < 10

UGR is a glare rating. Perceived glare also depends on luminaire placement, viewing direction and room reflectance.

Four expressions.

Focus on a collectible, illuminate a painting or spread a gentle brightness. Different beam angles give light different roles in a space.

A balanced 36° beam for layered lighting.

Adjustable models support up to 30° of aiming adjustment. Choose fixed-beam and asymmetric wall-wash models according to their optical design. Beam angle depends on the ordered configuration. Perpendicular beam diameter is estimated as 2 × distance × tan(beam angle ÷ 2).

JINKHOME product test reference · Darkroom photometry and illuminance. Data is based on the Indoor Luminaire Test Report, at 25.3°C and 65% humidity, using the C-Gamma method, a scan speed of 5.0°/s and a test distance of 11.000 m. This test distance and the reported heights in the illuminance chart above describe different measurements. Darkroom results do not represent actual illuminance in a home.

About the JINKHOME test data

Spectral and darkroom photometric tests are listed separately. Expand the tables above for the two white-light samples' colour and electrical parameters, 15 colour rendering indices, luminous intensity across eight planes and illuminance at five heights.

The data applies to the tested HB-S11-12W samples under the listed conditions, and cannot be assumed for other configurations. UGR depends on room dimensions, surface reflectance and viewing direction. A lighting design must consider the actual room, layout and installation height.

Downloads are JINKHOME presentation editions retaining the recorded measurements, charts and test conditions. They are not newly issued independent test reports.

Bring good light into your home.

Matter is a smart home connectivity standard that works across brands. A compatible Matter driver configuration lets your lighting join supported platforms, scenes, voice control and daily automations.

Dot Stealth includes a driver. Matter connectivity, dimming and colour temperature adjustment depend on the supplied driver's protocol, functions and your home control setup.

Plan your home's lighting in a familiar Home app.

A driver is included with the luminaire. For Apple Home, check that the supplied driver supports the required Matter connection, and prepare the home hub and network required by the platform. Available lighting controls and scenes depend on the device's supported functions.

Explore the connection

The platform sends the scene. The driver responds. The luminaire lights up.

Matched driver included

No separate driver selection is required. Check the supplied driver's protocol and available controls before connecting to a smart platform.

Then check your home network

Requirements for a Matter controller, home hub or Thread border router depend on the supplied driver and platform. Matter does not always use Thread.

Finally, confirm the functions

Dimming, colour temperature adjustment, remote control and multi-platform sharing depend on the driver, platform and home setup.

From design to the light it creates.

Good light begins with
careful installation.

Plan luminaire positions, cut-outs, drivers and service access together, for a clean ceiling and easier maintenance.

Luminaire placement and distribution

Start with what you want to illuminate.

Choose fixed, adjustable or asymmetric wall-wash optics for the objects, walls and activity areas. Consider ceiling height when selecting power, beam angle and spacing.

Cut-outs and ceiling space

Overall dimensions are not cut-out dimensions.

Confirm the selected model's cut-out and fixing method. Allow space for wiring, cooling, the driver and servicing. Plan plaster-in installation before finishing the ceiling.

Driver and electrical connection

Plan the smart controls, too.

Use the supplied matched driver. Installation must be performed by a qualified electrician with power disconnected, following the wiring instructions. Allow space for the driver and servicing. Never bypass the driver to connect the luminaire directly to mains power.

Before you choose,
You may also want to know.

Can the luminaire connect directly to Apple Home or another Matter platform?

A matched driver is included; no separate purchase is required. Platform connectivity depends on the supplied driver's Matter protocol and functions. Prepare the controller, home hub and network required by your platform.

Is a driver included?

Yes. Dot Stealth includes its matched driver, with no separate selection required. Use the supplied driver and allow installation and service space as specified in the wiring instructions.

How do I choose round, square or double models?

Choose the form to suit the ceiling, then the light distribution for the task. Round and square models provide individual light points; double models place two beams at one location. Adjustable models change the beam direction, while asymmetric models illuminate walls.

Can it be installed in a shower or outdoors?

Dot Stealth is rated IP20 for suitable dry indoor environments. Do not install it directly in showers, outdoors or in locations requiring protection against moisture or splashing.

Can renderings and web demos replace a lighting design?

No. On-site results also depend on ceiling height, installation position, surface reflectance, the number of luminaires and the selected optics. Use a lighting design based on the actual project to determine illuminance, spacing and wall effects.
