The product
A node on the network, not just a power supply
DALI runs on two polarity-free wires and carries 64 addresses per line, organised into 16 groups with 16 stored scenes, dimming from 0.1% to 100%. DT6 handles dimming; DT8 adds colour control on a single address; D4i adds energy and diagnostic data from the same pair of wires.
The premium addressable tier has historically been supplied by imports. Our position is a DALI-2 certified driver engineered, assembled and tested in India — with local warranty handling and an engineering response measured in days, not quarters.
- Constant-current output regulated across the published power classes
- Short-address programming and query verified at end of line
- Dimming curve validated against the DALI standard, not datasheet claims
- Commissioning application for installers and specification teams
Power classes
Where each class is installed
| 20 W | Recessed downlights, 2×2 panels Hotels, retail, corridors, washrooms |
|---|---|
| 30–40 W | 600×600 panels, troffers Offices, classrooms, hospitals |
| 50–75 W | Linear high bay, battens, track Parking, retail, light industrial |
| 100 W | Warehouse high bay, street light Logistics parks, municipal roads |
| 120–140 W | Tunnel, flood, high-mast Tunnels, sports, ports, airports |
Interoperability
Tested against reference controllers and third-party gear on a live network before the test-house submission.
Enclosure options
Indoor bodies plus conformal-coated and potted variants for IP-rated outdoor and tunnel duty.
Thermal margin
Magnetics and component stress reviewed at the top of the ambient band, then proven in 60 °C burn-in.
Service model
Warranty register per project batch with serial-level build reconstruction.
One line builds the whole family: changeover between power classes is a fixture and program change, not a re-launch.
Technical specification
Indicative engineering envelope
Values shown define the platform family. Per-model datasheets are issued against the frozen configuration for the ordered SKU.

Certification
Independent verification, per model
DALI-2 is a product test. Test specifications derive from published parts of the device standard and run on approved equipment; results are submitted per model and independently verified before the listing is issued. That is the difference from self-declared "DALI compatible".
- DT6 — device type 207 of the protocol standard
- DT8 — device type 209, colour control on a single address
- Listing in the public product database with logo rights while membership is active
- Quoted directly in tender responses as evidence of scope
India compliance stack
- BIS CRS registration for control gear; IS 10373 series scope confirmed per model
- IEC 61347-2-13 for luminaire control gear safety
- CISPR 15 and IEC 61547 for emissions and immunity
- RoHS declarations and E-waste producer responsibility for the finished unit
- ISO 9001 quality management covering the production plant
Certification is an ongoing membership obligation
Only active members can certify, and a listing lapses if membership lapses. We carry that obligation as a standing programme item so a specified product stays provably certified for the life of the warranty.
Test & burn-in
What every unit proves before it ships
Dielectric withstand
1.5 kV AC plus insulation resistance measured on every unit at end of line.
Output accuracy
Constant-current regulation verified to ±3% across the load range.
Power quality
Power factor, total harmonic distortion, efficiency and standby power.
Protocol communication
Short address assignment and query answered on a real DALI bus.
Dimming curve
Full 0.1–100% travel checked against the reference curve.
Colour point
DT8 SKUs verified on target colour before release.
Burn-in soak
6–8 hours at 60 °C, then a complete re-test of the same parameters.
Reliability audit
Sampled surge, 85 °C / 85% humidity and thermal imaging on production parts.
The traceability argument
Serial number, DALI short address and firmware checksum are logged to MES for every unit, linked to the component lots that built it. Inside a five-year fixture warranty, that record is the only way to bound a population at risk instead of replacing a whole project.
Who specifies these
Customers and channels
Luminaire manufacturers
OEM supply of certified drivers integrated into panels, high bays, battens and street fixtures.
EPC and smart-city tenders
Project lots with listed certification, batch traceability and scheduled dispatch.
Specification & design consultancies
Product-database evidence, dimming and colour data, and commissioning support at handover.
Interoperability context
The addressable control-gear category is dominated by premium imports from European and Asian manufacturers, alongside fast-growing certified lines from Chinese makers and regional specialists. Domestic buyers — luminaire brands, contractors and tender authorities — mostly source certified drivers from abroad today. Our programme exists to change that for projects that need a certified, locally supported product.
Third-party brand names are the property of their owners and appear here only to describe the category and interoperability landscape.
