Model: DL-LWW2321

Overview
The DL-LWW2321 23x21mm Linear Wall Washer is an IP65-rated linear wall washer measuring 23x21mm with 48LEDs per piece. It offers 25°/35°/45°/35*45° beam angle options, 8~20W power range and dimmable drive, and is built to order in custom lengths of 0.5~3m custom for facade grazing, column and wall-washing projects.
Description
This 23x21mm linear wall washer lighting offers precision 25°, 35°, 45°, and 35x45° asymmetric beam angles for uniform architectural facade grazing. Delivering an 8 to 20W power range with smooth dimmable performance, selected LED chips eliminate edge halos across structural surfaces. Engineered with IP65 ingress protection and anti-UV materials, this robust fixture resists moisture, rain, and outdoor corrosion in demanding environments. An adjustable 270-degree mounting bracket and waterproof quick connectors simplify on-site positioning and series wiring for architectural lighting projects. Available in OEM custom lengths from 0.5 to 3m, factory-direct options support tailored shell finishes and color temperatures for wholesale project supply.

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.
What are the key specifications of #DL-LWW2321?
DL-LWW2321 | 23x21mm Linear Wall Washer Lighting 48LEDs/piece | IP65: 8~20W power. Photometric files, wiring diagrams and test reports are available in the downloads block on this page.
How bright is #DL-LWW2321 and how wide is the beam?
Beam angle is 25°、35°、45°、35*45°. Mounting depth, diffuser transmittance and LED pitch decide the final uniformity, so plan the channel depth together with the density rather than the wattage alone.
Is #DL-LWW2321 dimmable?
Dimming: Yes. It works with constant-voltage PWM, 0-10V, DALI or TRIAC control as long as the driver and controller match the input voltage. For flicker-sensitive spaces such as studios and hospitals ask for a high-frequency PWM driver.
