KAR Light
KAR Light: light in niches, steps and ceilings
LED lighting for stairs, niches 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.
01 · Who it is for
KAR Light: 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).
02 · What the system consists of
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
03 · How it works
How it works
- 01Light 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.
- 02Control is an add-on
A controller in the LED box and a wall panel give scenes, brightness and schedules. If they are off, the basic scenario still works.
- 03Stairs
Sensors 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.
- 04Calculated for the site
Power per channel, 24 V cable cross-section by length, power supply margin, box ventilation with a thermostat — calculated before purchase, not after.
04 · Three levels
Basic / Mid / Premium
- Everything in Basic
- A controller in the LED box: brightness, scenes, schedules
- A wall panel with our interface
- Light groups per room
- Everything in Mid
- Music-reactive light, with a safe children's mode
- Link with sound and the Smart Home
- A UPS for the stair lighting box, «night» and «guests» scenarios
The content of each level is confirmed after a site visit; the price is in the estimate, not on the site.
05 · What the work includes
- Site visit, measurements and a scheme for the site
- Equipment list and power and cross-section calculation
- Sourcing via KAR Supply (price options)
- Installation of profiles, strip, box, sensors
- Tests: stairs switch on with the hub off, box heating
- As-built scheme, cable-end labelling, instructions
What is not included
- Finishing works (tile, plasterboard) — a separate estimate, but we agree the details in advance
- The home switchboard and supply — separate work by project
- Certification of devices as a finished product for sale
06 · Stages of work
Stages of work
01
Request and photos
Plans, photos of niches and stairs, where you want light.
02
Visit and measure
Heights, ceiling angles, tile depth, cable routes.
03
Scheme and calculation
LED box, groups, power, sensor positions.
04
Options and sourcing
Basic / mid / premium, supplier comparison.
05
Installation
Cables and profiles first — before tile and ceiling; then strip and box.
06
Testing and handover
Check without the hub, heating, photos, scheme, instructions.
07 · Timing
- What affects timingScope and number of zones, the finishing stage on site, supplier availability and how fast decisions are made.
- When we name the timingAfter a site visit and calculation: it is fixed in the estimate and work plan, stage by stage. We do not promise fixed timing in advance.
- What must be done on timeCables and boxes go in before walls and ceilings are closed. Equipment can be chosen and installed later.
08 · What we need from you
- Floor plans or photos of the rooms; the electrical and finishing design if available
- Access to the site for a visit and measurements
- A decision on the level (basic, mid, premium) after the calculation
- One contact person who approves decisions and changes
- The finishing schedule, so cables go in before walls are closed

10 · FAQ
FAQ
The page describes the solution and is not a public offer. Composition and calculation are set after a site visit.
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?
A 24 V supply 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.
