Tunable White & CCT LED Drivers
Brightness and Colour-Temperature Control for Modern Lighting
JSK URJA develops tunable-white LED driver solutions for professional lighting, automation and OEM applications requiring brightness control and adjustable white colour temperature.
Lighting concept
What Is Tunable White Lighting?
Tunable white lighting allows a luminaire to vary the appearance of white light from warmer to cooler tones while also enabling brightness control where supported by the driver and control system.
No medical, wellness or productivity outcome is implied. Published model JUDCTDN-6-23W uses phase-cut CCT control and is not DALI DT8.

Technical questions
Frequently Asked Questions
What is a tunable white LED driver?
It is a driver/control solution designed to manage brightness and the balance between warm-white and cool-white LED channels, subject to the selected product and control method.
What is CCT control?
CCT control adjusts the appearance of white light from warmer to cooler tones by managing compatible white LED channels. It is distinct from RGB or full-colour control.
Is the published tunable-white driver DALI DT8?
No. JUDCTDN-6-23W uses phase-cut CCT control. DALI DT8 remains a technology topic pending product approval.
Can phase-cut control be used for tunable white lighting?
Phase-cut-based CCT control can be developed using suitable driver and control strategies. It must be specifically designed and is not supported by every phase-cut dimmer.
Does JSK URJA develop tunable white LED drivers in India?
JSK URJA develops tunable-white and CCT-control technology through its in-house R&D and production capabilities in India. Individual models are published after verification.
