Drivers & Controls
DALI-2 · 0-10V drive layer. Bluetooth 5.0 SIG Mesh scene control — Super Panel series with built-in gateway, no separate hub required. Native Matter / Thread drivers connect directly to Apple Home, Google Home and Alexa.
The Drive Layer Behind Every HCL Program
Circadian performance depends not just on the luminaire, but on what drives it. SUMLINK specifies drivers and control systems that support the full tunable white arc, ultra-deep dimming, and protocol-agnostic network integration — enabling the time-spectrum programs in the Lighting Programs Library to be deployed without ecosystem lock-in.
Tunable White — 2700–6500 K
Dual-channel drivers maintain independent control of warm and cool LED channels across the full colour temperature range. The smooth CCT arc enables M/P ratio management from morning activation (high melanopic ratio, ≥5000 K) to evening transition (low melanopic ratio, ≤2700 K) — aligned with CIE S 026 circadian lighting guidance.
Ultra-Deep Dimming — to 0.1%
T-PWM technology achieves flicker-free output down to 0.1% of rated lumen output. Low SVM (Stroboscopic Visibility Measure) performance across the full dimming range reduces visual fatigue complaints in prolonged-occupancy commercial environments, without affecting colour consistency at low levels.
Matter over Thread — No Hub Required
Native Thread radio enables direct integration with Apple Home, Google Home, Amazon Alexa, and SmartThings without a proprietary gateway. NFC on-site programming allows zone and scene configuration at the device level during installation — no network dependency required at commissioning.
Protocol-Agnostic Architecture
DALI-2 operates at the drive layer — handling precise dimming commands to the LED array. Thread operates at the network layer — handling mesh communication and ecosystem commands. The two layers are independent: no single-vendor lock-in at either level, and future protocol upgrades do not require driver replacement.
