Rigid wall washers cannot follow a radius and cannot fit a shallow reveal. Our silicone and TPU wall washers bend to a 60 mm diameter, seal to IP65 or IP67, and are specified by wash height — not by wattage.
Pick the constraint on your drawing and the range narrows to the bodies that fit it. Full specs are on every card, no hovering needed.

Every wall-washing problem we are asked to fix comes down to one of these four.
A rigid extrusion is a straight line. On a radius you butt short lengths together and every joint reads as a dark break — exactly where the curve is most visible.
Reach is set by beam angle, not power. Too wide and the wall is bright at the bottom and grey at the head; too narrow and you get a hot stripe.
Deep bodies need a deep pocket. On a slim soffit, a window head or a joinery detail, a 20 mm-plus profile simply will not go in.
UV turns cheap PVC opaque, and a body that is only shower-resistant fails in a drainage channel or under a pressure washer.
Read down the middle column for what we do; read the right column for which family to specify.
| On-site problem | What we do | The number to check | Specify |
|---|---|---|---|
| Joints show on a curved wall | Continuous bendable body — the run turns with the wall instead of being cut into chords | Bending Ø 60 / 100 / 150 / 400 mm | HL-WL1616 · HL-WL2Q48 · HL-WL13Q · HL-WL2620Pro |
| The wash does not reach the top | Beam angle selected from the wall height, backed by a published wash-height chart | 6 angles, 15° to 20×55° | HL-WL2620Pro |
| No depth for the fixture | Ultra-slim body that still produces full wall-washing output | 18.5 × 9.5 mm · 1,919 lm/m | HL-WL2Q48 |
| Water ingress in a channel or under a hose | PU-potted TPU body, or one-piece silicone extrusion | IP67 / IP65 | IP67: HL-WL2Q48 · HL-WL13Q36 · HL-WL13Q42 |
| Scallops and dark bands on the wall | Optical lens, plus an asymmetric polarised option for wide, flat coverage | 30°/45°/60°/20×45° · polarized 115×50° | HL-WL2Q48 |
| A colour run has to follow the architecture | Addressable colour built into the same bendable body | DMX512 · 6 pixels/m · 256 grey levels | HL-WL13Q36 · HL-WL13Q42 · HL-WL2620Pro |
Find your wall below. Each one names the families that suit it and why.

The hardest case for a rigid washer, settled in a single run. No joints on the radius, no chord-cut gaps.

Set the body in the soffit and let it graze the wall above. Six beam angles match the reach to the wall height.

CRI 90 keeps stone, stucco and paint reading true. The slim body disappears into a shadow gap instead of sitting on the surface.

Colour runs and chases built into the wall line — addressable per pixel, following the curve without a visible joint.

Cut on site to match each flight. 5 m from one feed, or 10 m in total by feeding the middle of the HL-WL1616.

PU-potted TPU and one-piece silicone both resist salt, acid, alkali and UV — so a coastal installation does not yellow or craze.
Work down the list. Most specification mistakes happen because the wall is chosen last.
Wall height and the distance you can hold the body off the wall set the beam angle — and therefore the wash height.
Measure the tightest radius on the drawing. Minimum bending diameter is 60, 100, 150 or 400 mm.
IP65 for covered and shower-exposed positions; IP67 where the run sits in a channel or on a coastal elevation.
Single colour, tunable white, RGB, RGBW or DMX512 — decided by what the operator changes after handover.
Almost no one publishes this. On the HL-WL2620Pro, here is the wall-washing height for each beam angle at four mounting distances.
| Beam angle | Body 300 mm from wall | 200 mm | 100 mm | 50 mm |
|---|---|---|---|---|
| 15° | 800 mm | 1,000 mm | 1,400 mm | 1,700 mm |
| 30° | 600 mm | 900 mm | 1,100 mm | 1,300 mm |
| 50° | 550 mm | 750 mm | 900 mm | 1,100 mm |
| 18×20° | 1,000 mm | 1,300 mm | 1,500 mm | 1,800 mm |
Measured with the body held at the stated distance from the wall. The narrower the beam, the higher the wash — and the closer the body, the higher it climbs. Every other family ships with its own chart, which we send with the quotation.
Red VHB backing for a smooth, prepared wall. Fastest route where the surface is flat and clean.
Clips that match the body colour, so the fixing disappears against the wall.
For coastal and high-wind elevations, or anywhere tape alone is not accepted.
The angle can be set after installation, then locked — the most forgiving option on an uneven substrate.
| Family | Section (W × H) | Cut unit on site | Max run from one feed | Body material |
|---|---|---|---|---|
| HL-WL1616 | 16 × 16 mm | 20.83 mm | 5 m — 10 m with a mid feed | Silicone |
| HL-WL2620Pro | 26.5 × 20.5 mm | 250 mm | 5 m | Silicone |
| HL-WL2Q48 | 18.5 × 9.5 mm | 125 mm | 5 m | TPU + PU potting |
| HL-WL13Q42 | 18.5 × 9.5 mm | 166.6 mm | 5 m | TPU + PU potting |
| HL-WL13Q36 | 18.5 × 9.5 mm | 166.6 mm | 5 m | TPU |
Send the wall height, length and finish. We return a fixture layout with the beam angle, the offset from the wall and the spacing between runs.
Pre-production samples for approval before mass production, so the wash and the finish are signed off on the real wall.
Every wall washer family carries a 3-year warranty, across silicone and TPU bodies alike.
Custom length, colour temperature, CCT variants and control protocol — including end caps, connectors and clips to finish the run.
1How far from the wall should the fixture sit, and how high will it wash?
Both are set by the beam angle. On the HL-WL2620Pro a 30° beam reaches about 600 mm up the wall with the body 300 mm away, and about 1,300 mm when you move it in to 50 mm; the 15° beam reaches 1,700 mm at 50 mm. Each family ships with its own wash-height chart.
2Can it follow a curved wall? What is the minimum bending diameter?
Yes — every family is a bendable silicone or TPU extrusion rather than a rigid fixture. Minimum bending diameter is 60 mm on the HL-WL1616, 100 mm on the HL-WL2Q48 and HL-WL13Q36, 150 mm on the HL-WL13Q42 and 400 mm on the HL-WL2620Pro.
3Do I need IP65 or IP67?
IP65 (HL-WL1616, HL-WL2620Pro) is dust-tight and resists water jets. IP67 (HL-WL2Q48, HL-WL13Q36, HL-WL13Q42) adds tolerance to temporary immersion — specify it where a run sits in a drainage channel or gets hosed down. All five are DC24V and built for permanent outdoor installation.
4Silicone or TPU — which one should I specify?
HL-WL1616 and HL-WL2620Pro use optical-grade silicone, which stays soft at low temperature and resists UV, salt, acid and alkali. HL-WL2Q48, HL-WL13Q36 and HL-WL13Q42 use TPU, chosen for yellowing resistance in a slimmer 18.5 × 9.5 mm section; the 2Q48 and 13Q42 bodies are PU-potted. Both are outdoor materials — the real choice is section size and bend radius.
5How long a run can I feed from one end?
A single feed drives 5 m. On the HL-WL1616 you can reach 10 m in total by feeding the run from the middle — 5 m to each side. For longer elevations, plan a feed point roughly every 5 m.
6Can I dim it, or run RGB, RGBW and DMX512?
The HL-WL2620Pro is PWM controlled and is available in single colour, tunable white (2700K + 6500K), RGB, RGBW and DMX512. The HL-WL13Q36 is DMX512-addressable at 6 pixels per metre with 256 grey levels — RGB at 8.5 W / 230 lm/m, or RGBW at 11.5 W / 770 lm/m. The HL-WL13Q42 comes as RGB (6.2 W / 264 lm/m) or RGBW (8 W / 540 lm/m).
7How is it mounted, and can it be cut on site?
Four fixings are standard: 3M VHB tape, silicone clips, stainless steel clips, or an aluminium profile with rotatable brackets that let you set the angle after installation. Every body is cuttable on site — every 20.83 mm on the HL-WL1616, 125 mm on the HL-WL2Q48, 166.6 mm on the HL-WL13Q36 and HL-WL13Q42, and 250 mm on the HL-WL2620Pro.
8What warranty, sample and MOQ terms do you offer?
Every wall washer family carries a 3-year warranty. Pre-production samples and volume pricing are available on request, and MOQ is set per SKU — tell us the project schedule and quantities and we will confirm both in writing.
