Description
DL-LWW2321 | 23x21mm Linear Wall Washer Lighting 48LEDs/piece | IP65 Featuring versatile optical options including 25°, 35°, 45°, and a specialized 35×45° asymmetric lens, this fixture provides targeted light distribution for varying wall heights and throw distances. The 35×45° oval beam angle optimizes light efficiency by directing energy precisely along the vertical facade, minimizing ambient light spill, optical distortion, and glare. Superior Color Quality.Selected LED chips with high color rendering and strict capacity division ensure high color consistency when multiple lamps are continuously spliced. After secondary optical structure optimization, there are no mixed color halos or yellow circles at the edge of the light output, which can truly restore the delicate texture of stone, wood grain, and wall coatings. Engineered to IP65 ingress protection standards, the linear fixture features specialized sealing compounds and anti-UV optical materials to resist moisture, rain, and UV degradation. The corrosion-resistant anodized/powder-coated finish ensures long-term structural integrity in both challenging outdoor elements and indoor damp environments. Equipped with a 270 ° adjustable angle mounting bracket and waterproof quick connect connector, it greatly simplifies on-site construction positioning and multi lamp series wiring. Simultaneously supporting personalized engineering options for customized length, color temperature, and shell color. Ideal for architectural facade grazing, indoor ceiling coves, landscape retaining walls, bridge accents, and commercial gallery displays.

Frequently Asked Questions
What beam angles are available for the DL-LWW2321 23x21mm Linear Wall Washer?
Beam angle options are 25°/35°/45°/35*45°, so you can grazing-wash a facade or spread light evenly across a wall from a longer standoff distance.
Is this linear wall washer suitable for outdoor use?
Yes. It is IP65 rated against dust and low-pressure water jets, which suits covered outdoor facades, canopies and landscape walls. For continuous immersion or heavy pressure washing, ask us about higher IP options.
Can the length and power be customised for my project?
Yes. Standard build is 0.5~3m custom with a power range of 8~20W. Send your run length, mounting method and control (dimmable / DALI / 0-10V) requirements with your quotation request and we will configure the fixture.
