KAR Light
KAR Light: light in niches, steps and ceilings
Our solution for LED strip installation: profile, 24 V strip, power supply and control are put together in one scheme and calculated for your site. The main rule: basic lighting comes on even when the hub, the network and the controller are off.
Status: the solution is in a pilot on a real site in Phuket; the control hardware is being tested on a bench. It is a project-based solution for a site, not a boxed product in a shop.
Who it is for
- Owners of villas and flats whose project has lighting in niches, on stairs, in ceilings and in the top row of bathroom tile.
- Lighting installers and integrators who need a proven scheme and calculation.
- Venues: bars, restaurants, hotels, showrooms — light scenes and one control panel (after the pilot).
01
How it works
- Light separate from «smart»The strip is fed by a 24 V supply through a separate fuse on every branch. Motion-sensor switching goes through a relay — no hub, no Wi-Fi, no ESP32.
- Control is an add-onA controller in the LED box and a wall panel give scenes, brightness and schedules. If they are off, the basic scenario still works.
- StairsSensors at the bottom and top of the stairs. Two scenarios: a «wave» (steps light one after another) and «all at once». The cable is laid for the «wave» and fits both.
- Calculated for the sitePower per channel, 24 V cable cross-section by length, power supply margin, box ventilation with a thermostat — calculated before purchase, not after.

Components and scheme
| 24 V LED strip | Warm or neutral white; IP65/67 for wet areas |
| Aluminium profile + diffuser | Surface, recessed into tile, in a niche, on a step; fitted to tile depth and ceiling angle |
| 24 V power supply | A separate output for each group; power margin and tropical heating allowance |
| LED box | A cabinet with terminals, a DC fuse on each branch, a fan and a thermostat |
| Motion sensors | Bottom and top of each stair, corridors; power and signal on a separate cable |
| Controller and panel (add-on) | ESP32 controller, a wall panel for an 86 box powered at 24 V DC, a Telegram Mini App for scenes |

FAQ
What if the hub or Wi-Fi is off?
Basic lighting and stair lighting keep working: the supply and the sensor with a relay do not depend on control. This is a pilot criterion — checking stair switching with the hub and controller off.
Is 24 V safe?
Low voltage lowers the risk but does not remove the need to calculate: power per channel, cross-section, protection of each branch, supply heating in the tropics. All of it is in the scheme. Where the law requires a licensed specialist's signature, we bring in a partner.
Can it be installed in finished interiors?
Yes, but with surface profiles and exposed routes. Recessed solutions and hidden cables are better before tile and ceilings.
Do you sell KAR Light separately?
Not yet: it is a solution for a site with installation. Selling a finished device would need separate certification.
Warranty and support?
Terms are fixed in the contract with the executing partner. The scheme, list and instructions stay with you, and elements can be replaced without our software.
The page describes the solution and is not a public offer. Composition and calculation are set after a site visit.
