Recommended 24V power supply
BG-0318-2824-0640 uses 50W per sheet at 24V DC. We size drivers at 80% of rated output, so they run cool and leave headroom:
| Power supply | Rated output | Max sheets per driver (80% load) |
|---|---|---|
| Mean Well LRS-350-24 indoor, dry locations |
350W | 5 |
| Mean Well HLG-320H-24 IP67, damp locations |
320W | 5 |
For larger layouts, split the sheets into groups with one driver per group and feed each group separately. See all 24V LED power supplies for light sheets, or send us your layout for a free power plan.

Where the BG-0318 LED Sheet Works Best
BG-0318 is the high-density RGBCCT sheet: 640 small LEDs give a smooth surface for color scenes and high-CRI tunable white from the same panel. It suits premium backlit stone, hotel and restaurant feature walls and showrooms.

Cutting and Installing the BG-0318 LED Light Sheet
The BG-0318 is a flexible LED sheet on double-layer FPC, 1.6 mm thick, with 3M adhesive backing and screw-mount accessories. It can be cut along the marked lines with a minimum cutting unit of 30.6 × 30.6 mm; shapes follow that grid. Sheets can be joined with the supplied connection wires to cover large areas. For backlit stone, onyx, marble or resin, mount the sheet 30–80 mm behind the surface: thin, highly translucent materials need the larger distance or a diffuser, while denser materials can sit closer. Allow for the height of the input connector when planning the cavity.
Matching Power Supply and Controller
The BG-0318 uses 6-wire input (V+, R, G, B, warm white, cool white) at DC 24V. With a Mean Well HLG-320H-24 (320 W) loaded to 80%, one driver powers about 5 sheets of BG-0318; a Mean Well HLG-150H-24 powers about 2 sheets. Keep each driver at or below 80% of its rated power and split large surfaces into several zones rather than using one very large driver. For dimming and color control we recommend a 5-in-1 RF controller such as the HX-SZ900-R5 (RGB+CCT mode, up to 960 W at 24V). It also supports wireless and RJ45 wired sync between zones. Do not combine a dimmable driver with a PWM dimming controller in the same zone.
BG-0318 vs Similar LED Sheets
Compared with BG-0297 (360 × SMD5050, 125 mm cut), BG-0318 has a finer 30.6 mm cutting grid and Ra >95 white, so it is the better choice for shaped panels and thin stone.
BG-0318 LED Sheet FAQ
Can the BG-0318 LED sheet be cut to a custom shape?
Yes. Cut only along the marked lines; the smallest cutting unit is 30.6 × 30.6 mm, so curves and angles follow that grid. Send us your drawing and we will check the layout before production.
How much space do I need behind the stone or panel?
We recommend 30–80 mm between the LED sheet and the translucent surface. Thinner, more translucent materials need more distance or a diffuser to hide the LEDs; the sheet itself is 1.6 mm thick, plus the height of the input connector.
What is the minimum order, and can I get a sample?
Orders start from one sheet. Samples are available for a fee and usually arrive in 7–10 days, including shipping.
Which power supply and controller should I use?
BG-0318 is a DC 24V product. With a Mean Well HLG-320H-24 (320 W) loaded to 80%, one driver powers about 5 sheets of BG-0318; a Mean Well HLG-150H-24 powers about 2 sheets. For control we usually recommend a 5-in-1 RF controller such as the HX-SZ900-R5 (RGB+CCT mode, up to 960 W at 24V).
