Quick Answer:
LightWave® Roll It! runs up to 40 ft (480″) continuous in the standard format, 4″ wide, at 2.15 W/ft and 130 lm/W. The high-output roll runs 33 ft 4 in at 3.5 W/ft. One correctly sized driver can power a full standard roll, so long coves, signs and bar fronts can be lit without splices.
Large-format LED light sheets ship in continuous rolls up to 40 feet — long enough to cover expansive feature walls, backlit signage, transit corridors and trade-show backdrops as one seamless run instead of a stitched grid of panels. For designers and contractors sizing a wall bigger than a standard 12″ × 24″ sheet, a large-format roll is usually the right specification.
LightWave® Roll It! is the rollable member of the flexible LED light sheet line — same ultra-thin (<7 mm) profile, same adhesive-backed, cuttable substrate, delivered on a spool for fast on-site handling and one uninterrupted power run.
What Is a Large-Format LED Light Sheet?
A large-format LED light sheet is a continuous, flexible LED backlighting substrate delivered in a roll rather than a fixed panel. It gives designers the ability to specify one long, seamless run across an entire surface — no visible seams, no cumulative brightness variation from panel to panel, and only one power supply for the whole length.
LightWave® Roll It! ships in continuous rolls up to 40 ft. Cut along marked lines to length, peel the adhesive backing, apply, connect to a single driver at one end.
How long is a LightWave® Roll It! roll?
Powering one long section instead of several smaller panels changes the install economics:
- Fewer drivers and power supplies
- Fewer splices and connectors
- Less wiring clutter behind the surface
- Faster on-site handling — one roll, one run, one termination
- Consistent brightness end-to-end (no panel-to-panel drift)
“Roll It! eliminates the biggest challenge with large installations—seams. At 40 feet continuous, we can light entire walls with perfect uniformity.”
— Aweyer, Lighting Applications Engineer, LUXX
What is the difference between standard and high-output Roll It!?
Roll It! ships in two verified format families. Both are 4″ wide and adhesive-backed with CRI >80. The difference is Kelvin range and light output per area:
| Format | Length | CCTs Available | Power / ft | Output / ft | Efficiency |
|---|---|---|---|---|---|
| Standard Roll | 4″ × 480″ (0.1 × 12.2 m) | 3500K, 5000K, 6500K | 2.15 W/ft (7 W/m) | 280 lm/ft (920 lm/m) | 130 lm/W |
| High-Output Roll | 4″ × 400″ (0.1 × 10.16 m) | 1800K, 2700K, 3000K, 3500K, 4000K, 5000K, 6500K | 3.5 W/ft (11.7 W/m) | 350–450 lm/ft (1170–1520 lm/m) | 115–130 lm/W (100 lm/W at 1800K) |
Choose Standard when the design specifies daylight white and efficiency matters more than absolute brightness — typical for retail feature walls and general architectural backlighting. Choose High-Output when the design needs warmer CCTs (hospitality, restaurant, residential) or when the diffuser or material sitting in front of the light is heavy and needs more lumens per square foot to punch through.
Why does a continuous roll need fewer drivers?
Every splice between LED panels is a potential brightness drift, a potential failure point, and a labor line item. A 40 ft continuous roll replaces what would otherwise be roughly twenty 12″ × 24″ panels stitched together — with all their driver leads, connectors and visible seams.
To size the driver for a run, multiply the run length by the power-per-foot figure above (add 15–20% headroom). Or use our LED power supply calculator to get an exact figure with headroom baked in.
Where is a large-format LED sheet roll used?
- Retail display walls — one continuous glow behind a full-height feature wall
- Backlit signage and billboards — long-format channel letters, halo-lit signs, static graphics
- Airport, subway and transit corridors — continuous overhead or wall runs down long circulation zones
- Trade show booths and event backdrops — full-height backlit brand walls, fast install and teardown
- Long hallways, staircases and corridors — wayfinding light, no visible fixture, no repeating hotspots
- Warehouse and industrial task lighting — continuous under-shelf or work-zone illumination
- Architectural cove lighting — long ceiling and wall coves, one driver per cove instead of one per section
Can you combine rolls and sheets?
Roll It! covers the primary square footage of a large surface quickly. When the design hits an intricate corner cutout, a curved column, or a structural obstruction, connect a Gen 1 Plus sheet to the roll. The two are engineered to match — same LED spacing, same output, same color — so the transition is seamless and the whole surface reads as one uninterrupted glow.
See our cuttable LED sheets page for how to trim to any custom shape on site.
How do you install an LED light sheet roll?
Cut to length along marked lines. Peel the adhesive backing. Apply to a clean, flat or gently curved surface. Connect to a matched constant-voltage driver sized for the run length. For installs behind fabric or diffuser panels, use the screw spacer set to hold the sheet off the forward material — this controls hotspots and dissipates heat.
