Super Long 2700K to 6500K Tunable Circadian LED Light Sheet Roll - Translucent Stone Backlighting

Designed specifically for backlighting onyx, marble, quartz, resin panels and all translucent surfaces, this revolutionary 240mm wide × up to 10m long rollable light sheet delivers perfectly seamless, dot-free illumination while mimicking natural daylight cycles (2700K warm sunrise → 6500K cool daylight). Ultra-thin, fully cuttable every 21.83 × 21.83 mm, and equipped with built-in screw terminals every 0.5 m – it is the ultimate Human Centric Lighting (HCL) solution for luxury feature walls, reception desks, bars, elevators and wellness spaces. The real game-changer of this ultra-long light sheet is that you buy one single roll, cut and shape it exactly to your project on-site, and still only need one single power injection point — no matter how you configure it.

► Want a perfect 3m × 1.2m L-shaped bar front? Just cut and fold one continuous piece — seamless corner, no visible joints.

► Need to cover a 8m tall full-height onyx wall? Unroll, cut to height, stick — one sheet, one feed, perfectly uniform from top to bottom.

► Running multiple separate panels (e.g. reception desk + side walls)? Cut the roll into any lengths or shapes you need and simply parallel them — still only one power supply and one controller for the entire installation.

We also offer RGBW color changing version for dynamic backlighting. 

Installation Advantages & Smart Control

Cut to exact length on site – no wasted material

Four dedicated solder pads per cut unit for emergency wiring if needed

Board-to-board & board-to-power connection via screw terminals (no soldering, just a screwdriver)

Maximum single-run length on 24 volts: 10m/32.8ft (almost no voltage drop)

Compatible with any external CCT controller, DALI-2, 0-10V, Bluetooth, RF, WiFi, Zigbee, or even simple wall switches (via dimmable driver) for manual circadian tuning

Perfectly flat back + adhesive for direct mounting behind stone within 3–5 mm gap

Advantages over other light sheets

90% less connection work compared to traditional segmented panels

Zero visible seams or frame lines for true floating-stone luxury look

Drastically reduced installation time and cost

Maximum design freedom with minimum electrical complexity

One roll in your hand = infinite custom shapes and sizes, always powered by just one cable. That’s the real meaning of “Super Long” circadian backlighting.

 

Circadian Rhythm Sheet Lighting Control – Simple, Powerful

One full 10m roll at maximum brightness consumes 24V / 520W / ≈22A, so we pair it with rock-solid, installer-favourite components that handle the whole roll (and leave headroom) - products in the kit:

Controller: Mi-light HW2 (need to switch to the 2-channel tunable white output)

– Supports both RF remote (purchase separately) and WiFi/App control (iOS/Android/Tuya/Alexa/Google Home)

– Built-in 30A capacity → comfortably drives the entire 10m roll + extra zones if needed

– Smooth 2700K warm sunrise → 6500K cool daylight transitions, 0–100% dimming, timer & circadian auto-mode presets included

Power Supply: Mean Well UHP-750-24 (750W / 31.3A @24V, UL-listed, PFC, fanless)

– More than enough headroom for a full 10m roll even at 100% brightness

– Ultra-reliable, 5-year warranty, runs cool and silent – perfect for luxury lobbies and hotel installations

Just connect the two outputs of the HW2 controller to the compatible screw terminals on the roll (or parallel multiple sections), plug into the UHP-750-24, and you’re done — one controller + one PSU runs up to 10 seamless meters of dynamic circadian backlighting.
