Quick Answer:
Roll It! ships in continuous lengths up to 40 ft, which covers most large-format runs without a splice. Standard draws 2.15 W/ft and High-Output 3.5 W/ft, so a full 40 ft run needs roughly 103 W or 168 W respectively with 20% headroom applied. Fewer joins means fewer drivers, fewer splices, and no dark intervals across the surface.
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.
LightWave® Roll It! — Up to 40 ft Continuous
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)
Two Roll Formats: Standard vs High-Output
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.
Fewer Drivers, Fewer Splices, Cleaner Install
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 Large-Format LightWave® Fits
- 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
Combining Rolls with Cuttable Sheets for Custom Shapes
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.
Installation Overview
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.
Large-Format LED Light Sheet FAQs
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. LightWave® Roll It! ships in continuous rolls up to 40 ft, letting designers specify one seamless run instead of a stitched grid of panels.
How long can a LightWave® roll run continuously?
Up to 40 feet in a single continuous run, powered from one driver at one end.
What is the difference between the Standard and High-Output roll?
The Standard roll (4″ × 480″) ships in 3500K, 5000K and 6500K daylight whites at 2.15 W/ft with 130 lm/W efficiency. The High-Output roll (4″ × 400″) ships in the full range from 1800K amber through 6500K daylight at 3.5 W/ft with 350–450 lm/ft output — brighter per foot, warmer CCTs available, higher power draw.
Can I combine a Roll It! run with cuttable LightWave® sheets?
Yes. Roll It! and Gen 1 Plus sheets are engineered to match, so you can run the roll across primary square footage and drop in cuttable sheets for curved cutouts, columns and custom shapes without visible seams or brightness mismatch.
How many drivers do I need for a 40 ft run?
One matched constant-voltage driver, sized to the total wattage of the run plus 15–20% headroom. Multiply run length by the power-per-foot figure — 2.15 W/ft for the Standard roll, 3.5 W/ft for the High-Output roll — or use our LED power supply calculator.
Is Roll It! cuttable?
Yes — cuttable along marked lines to any length you need on site, same as every other LightWave® variant.
