I’ve got a resin panel and a stone slab, and I assumed one light sheet would treat them the same. It doesn’t. Stone varies across the slab, so colour can change from vein to vein, while resin is more consistent but its tint can shift the white I see.
Variation versus tint
Stone is natural. One slab can have dense, dark veins next to lighter areas, and light does not pass through them equally, so the same sheet can look strong over a light section and muted over a dark vein.
Resin is made, not quarried, so a panel tends to pass light far more evenly. What resin adds instead is tint: a warm-toned or coloured resin filters the light, so a white that looked clean behind stone can look warm or slightly off behind resin.
Colour shift: why the white channel matters more for resin
For stone, one fixed white must survive the slab’s variation. For resin, I often need to tune white against the tint.
The BG-0318 RGBCCT sheet gives me room to adjust, with both a 2700K warm white channel and a 6000K cool white channel, on a 6-core layout (V+/R/G/B/warm/cool), with 640 LEDs on a 490×245mm sheet, at 24V and 50W. Testing both against the actual resin shows which cancels out the tint.
The BG-0313 RGBW sheet leaves less room: 512 LEDs, 45W, 5 cores, but its white is only 3000K or 6000K, so I pick one before ordering, and the sample test has to settle it.
The BG-2002 single-colour sheet suits a job where one tested white already suits both materials: 288 LEDs, 610×305mm, 30W, Ra>95, with no second white to fall back on.
One catch applies to RGBCCT. A normal RGB controller is 3-channel, and it cannot drive the two white channels of a 6-core RGBCCT sheet, so for warm-to-cool tuning I confirm RGBCCT support before ordering.
| Sheet | White | Why it matters |
|---|---|---|
| BG-0318 RGBCCT | 2700K + 6000K | Most room to correct resin tint |
| BG-0313 RGBW | 3000K or 6000K | Pick one white from testing |
| BG-2002 single-colour | One fixed colour | Works when one white suits both |
Testing stone and resin is not the same test
For stone, I test with the real slab, not a photo or a chip from a different batch. I check the darkest vein and the lightest area on the same piece, and look at the full face rather than one bright spot.
For resin, I test with the production resin in its exact colour and thickness, not a clear sample, which tells me almost nothing about tint shift. I test warm and cool white separately, compare the centre with the edges, and note which white I preferred. In a wet area, I confirm the IP rating and driver placement suit it, without assuming a rating for a specific model.
Two physical details matter for either material. The glowing area is 1.6mm thick and the connector is 5.6mm, so I allow 6mm at the connector and 2mm at the glowing area. Larger panels may need multiple sheets spliced on their 3M adhesive backing, and I check the joint too.
For dot-hiding distance, I do not treat stone numbers as a shortcut for resin: stone bands are only a starting point, and the final result always depends on a sample test with the real panel. Distance is covered in the separate resin post: how distance behind a resin panel differs. For stone, see LED light sheet distance to hide LED dots.
Checklist before I choose
- Test the real slab or real resin, in final colour and thickness?
- Stone: checked the darkest vein, not just the brightest area?
- Resin: tested warm and cool white separately?
- Controller supports both whites on a 6-core RGBCCT sheet?
- Allowed 6mm at the connector and 2mm at the glowing area?
- Wet area: confirmed IP rating and driver placement?
FAQ
Can one sheet suit both resin and stone?
Often yes, but I would not assume the same white setting works for both. Test behind each material separately.
Why does resin look different under warm and cool white?
The resin tint filters the light, and warm and cool white interact with that tint differently. Testing both channels on the BG-0318 is more reliable than picking from a chart.
Why is my stone test uneven when my resin test is even?
Stone varies naturally, so a dense vein can read darker than the area beside it. Resin is more uniform, so unevenness there more often points to tint or a joint.
Do I need a different controller to tune white for resin?
I need a controller that matches the sheet. A normal 3-channel RGB controller cannot drive the two white channels of a 6-core RGBCCT sheet.
To be sure, test against the real panel. See the flexible PCB LED light sheets page, then request a quote or a sample and mention the panel material and colour.
