Say goodbye to that dotted line of LEDs showing through your channel. This is the 4 Feet Opaline Diffuser for Aluminum U Shape Profile (SKU DIFF4-OPAL) by LED MONTREAL, a replacement lens — also called a cover, lens or snap-in cover for an LED aluminum channel — designed to slide straight into the LUX710, LUX740, LUX745 and LUX747 extrusions. If you already have a profile installed and you are searching for an aluminum profile for LED strip lighting diffuser that finally hides the chips, this is the piece you are looking for. People shop for it under many names: diffuser for aluminum extrusion, frosted-style lens, opal cover, or simply the white strip that clips on top of an LED channel. It is sold on its own, so you can change the look of an existing run without buying a whole new profile.

The diffuser type here is Opaline, the most closed of the diffuser family. Where a clear lens shows every chip and a frosted lens still reveals pixels once the strip is on, opaline scatters the light so you read a smooth, continuous line of light instead of individual dots. That makes it the go-to choice for anyone bothered by visible LED dots in a cove, a shelf or a handrail. It measures 4 feet long, matching the standard channel sizing, and it is cut to the U shape geometry of the LUX710, LUX740, LUX745 and LUX747, so it snaps in and stays put. It also closes the top of the profile, which keeps dust and fingerprints off the tape underneath and gives the whole assembly a clean, factory-finished look.

Contractors and homeowners reach for this opaline lens in kitchens under upper cabinets, in bedroom coves and tray ceilings, along staircases and baseboards, in retail display cases, reception desks, bar fronts and office millwork — anywhere the light matters more than the light source. It fits the 8 feet interior aluminum U shape profile for LED strip (LUX710), the 8 feet aluminum U shape profile for LED strip (LUX740), the recessed 8 feet recessed aluminum U shape profile for LED strip (LUX745) and the 8 feet aluminum U shape profile for LED strip (LUX747). Order the length you need and turn that dotted strip into one clean band of light.

What this part is
The DIFF4-OPAL is a stand-alone diffuser for an aluminum U shape LED profile — the lens portion only, with no channel and no LED strip included. It is meant for two situations: replacing a lens that was scratched, damaged or lost during a renovation, and switching diffuser styles on a profile that is already installed because the light looked too raw or too dotted. Because it ships as its own item, you can mix styles across a project: a clear or frosted lens where you want maximum output, and this opaline lens where the light source sits at eye level and needs to disappear.

Light quality: why opaline
Diffusers are a trade-off between brightness and how much of the LED you can see. A clear cover renders about 98% of the strip's light but shows every chip. A frosted cover renders about 85% and softens the chips when the strip is off, yet pixels still show through once it is powered. Opaline is the answer when a dot-free, continuous line of light is the priority — it blends the individual emitters into a single uniform glow. That is why it is the usual pick for coves, shelves, handrails and any run seen straight-on. Keep in mind that a more closed diffuser softens more light, so plan a slightly brighter or denser LED tape if the run also has to work for task lighting.

Installation and compatibility
Installation takes no tools and no wiring: the lens slides or snaps into the track at the top of the U channel and can be pulled back out if you ever need to service the tape. Fit the LED strip and its wiring first, test the run, then close it with the diffuser — that way you are never prying a lens off a finished ceiling. For long runs, butt two 4 foot sections end to end and keep the seams away from sight lines, or line the seam up with a profile joint. Verify your channel model before ordering, since this lens is cut for the U shape geometry of the LUX710, LUX740, LUX745 and LUX747 only; it is not intended for other profile families. On the recessed recessed aluminum U shape profile (LUX745), plan the drywall or millwork channel so the lens finishes flush with the surface.

Applications and documentation
In homes, this diffuser is the finishing touch on under-cabinet kitchen lighting, pantry and closet shelving, bathroom vanity coves, basement stair nosings and tray-ceiling perimeters. In commercial work, it tidies up retail shelving and display cases, restaurant bar fronts, hotel corridors, reception desks, gym mirrors and office millwork — the kind of jobs where a client will absolutely notice a dotted strip. Canadian renovators also like that a spare lens can be swapped in years later without touching the aluminum extrusion or the tape. The technical PDF for this diffuser is available in the Documentation tab of this page for your submittals and job files. Pair it with the interior aluminum U shape profile (LUX710) or the aluminum U shape profile (LUX740) for a complete, clean install.
