Core advantages

Compact, precise and beautifully controlled.

Flash integrates optics, structure, glare control and accessories into one complete architectural lighting system, giving designers freedom without compromising performance.

01

Compact profile

25mm and 35mm linear profiles for subtle integration into architectural details.

02

Ice Cube Optics

Refined optical engineering for clean beams, high uniformity and efficient transmission.

03

Low-glare comfort

Nano Louvre and shielding options provide precise cut-off control.

04

Outdoor durability

IP66 protection and 1000-hour salt spray resistance for demanding environments.

01 / Compact body

Small profile, strong architectural presence.

Flash is available in 25×32mm and 35×32mm profiles, balancing discreet integration with professional output.

25×32mm profile: 18W/M and 24W/M.
35×32mm profile: 36W/M for higher output requirements.
Designed for façades, details, corridors and landscape structures.
02 / Ice Cube Optics

Refined optics for clean, elegant light.

The Ice Cube Optics system is engineered to create precise beam quality, high light transmission and smooth uniformity in a compact linear form.

Clean beam edges and controlled distribution.
High optical efficiency for architectural surfaces.
A distinctive optical identity for the Flash series.
03 / Asymmetric distribution

More light where the architecture needs it.

Advanced asymmetric distributions improve effective light utilization on the target wall, reducing unnecessary spill and visible glare.

Up to 85% use ratio for wall washing applications.
Up to 70% use ratio for mini-tilt wall grazing.
Stronger surface brightness with better visual comfort.
04 / Wall washing

Smooth vertical illumination for large surfaces.

Flash wall washing creates a clean and balanced wash across façades and interior feature walls, helping surfaces appear calm, bright and refined.

Suitable for 1000mm, 1500mm and 2000mm setback conditions.
Designed for high wall coverage and smooth brightness transition.
Ideal for hotels, public spaces and exterior façades.
05 / Wall grazing

Texture becomes visible through controlled contrast.

Flash wall grazing emphasizes material depth and vertical rhythm, revealing stone, concrete, timber and decorative surfaces with clarity.

150mm, 200mm and 250mm installation distances for different texture effects.
Strong visual depth for rough surfaces and crafted materials.
Stable beam performance with low-glare control.
06 / Sloped grazing

Precise light control for angled surfaces.

Flash sloped grazing maintains a clean perpendicular lighting effect even on inclined mounting surfaces, helping avoid dark areas and discomfort glare.

Designed for angled façades, canopies and sloped architectural forms.
Reduces visible glare compared with conventional tilted light.
Keeps architectural rhythm clean and visually comfortable.
07 / Nano Louvre

Glare control without losing the elegance of light.

The integrated Nano Louvre system shields the light source from direct view while preserving smooth beam quality and high wall brightness.

Integrated 60° cut-off angle design.
35° shielded viewing condition for improved visual comfort.
Suitable for pedestrian zones, corridors and close-view applications.
08 / Accessories

A complete system for real project conditions.

Flash supports multiple anti-glare and installation accessories, allowing the same product family to adapt to façades, landscapes, ground installations and structural details.

External visor, external louvre and internal Nano Louvre.
Surface mounting, extension arm, in-ground profile and ground spike.
Designed to simplify installation and maintain optical alignment.
09 / Reliability

Built for demanding outdoor environments.

With IP66 protection, architectural-grade powder coating and 1000-hour salt spray resistance, Flash is engineered for long-term stability in challenging environments.

Multi-step pre-treatment for superior corrosion resistance.
UV-stabilised surface finish for long-term outdoor appearance.
Breathing valve supports durability under changing outdoor conditions.
10 / Customization

Configured around the design intent.

Flash can be customized across power, optics, finish, installation accessories and wire outlet position, helping designers respond to specific architectural requirements.

Higher-power options for demanding projects.
In-house optics for particular applications.
RAL colors, white, bronze, green and tailor-made accessories.
Performance

High surface utilization. Low visual disturbance.

Flash improves how light reaches the target surface, supporting efficient, comfortable and expressive architectural lighting.

85%Use ratio for wall washing asymmetric distribution
70%Use ratio for wall grazing mini-tilt asymmetric distribution
60°Integrated cut-off angle with Nano Louvre system
System flexibility

A complete platform for architectural linear lighting.

Multiple optics, controls, finishes, anti-glare accessories and installation options support both standard applications and tailor-made project requirements.
