Backlighting works only when the chosen material transmits enough light. Do not assume every marble, quartz or countertop slab will glow. Keep front lighting as an option for opaque materials or for showing surface finish.
Test the actual slab before designing the display
Use a sample with the intended thickness, finish and backing. Check the veins, dark areas, visible LED points and edges under the venue’s ambient light. Compare it illuminated and unlit: backlighting changes the presentation and does not necessarily show the colour a buyer will see in normal use. Antolini’s Alluminate collection, for example, uses specially thinned stone for backlighting; it is not evidence that any untreated slab is suitable.
Choose the correct panel version
Our 480 × 240mm flexible stone backlight panel uses DC24V. Fixed-white versions are 3000K, 4500K or 6500K, each rated 24W with 288 LEDs; they need a compatible power supply, without a CCT controller. The 3000K+6500K tunable-white version is rated 48W with 576 LEDs and needs both a compatible power supply and CCT controller. A driver-only package does not supply that controller.
The listing specifies CRI90+ and a 120° beam. Neither CRI nor LED count guarantees the appearance through stone. Compare colour-temperature choices on the actual sample rather than assigning a mandatory temperature to beige, grey or white stone.
Plan coverage, mounting and access
Test the panel layout and distance to the slab before fixing the cavity depth. Look for dark seams, bright points and uneven edges; do not assume direct contact or one universal gap works. Have the stone fabricator confirm independent support for the slab: the LED panel is not its structural support.
This model specifies screw mounting, not an adhesive backing. Keep screws away from LED cells, conductors and connectors. Cut only along its marked 20 × 20mm grid; separated sections need correct reconnection and insulation. Confirm bend limits, heat dissipation and service access before building the enclosure. Do not infer a 0.6mm thickness or a permissible bend radius from the word “flexible”.
Size the electrical system and rehearse installation
Four fixed-white panels have a rated total of 96W; four tunable-white panels total 192W. Select a compatible DC24V supply, cabling and, where needed, controller for the complete connected load, using the equipment maker’s design margin and instructions. Do not connect these panels directly to mains power. Confirm polarity, connections and the venue’s electrical requirements for the complete assembly.
Run a full-size trial long enough to assess the installed system’s heat and lighting, then practise packing and assembly with the stone protected. There is no guaranteed five-minute assessment or 30-minute setup. Send dimensions, thickness, a sample or photos, available cavity depth and the desired fixed or adjustable colour temperature through our contact page before ordering.
