For those seeking a truly modular sign, or preferring to maintain a uniform look where rounded airfield signage is already installed, we are pleased to offer the patented D-Lux. The D-Lux is a formidable upgrade from standard curved signs. The appearance may be familiar, but the high quality and thoughtful engineering is refreshingly new.


• Patented modular curved sign design.
• Lowest VA loads: Most efficient ETL Certified L-858 signs available.
• Years of reliability, durability and performance.
• Withstands harsh weather conditions and jet blast.
• Uses quartz or incandescent 6.6A 45W lamps.
• Easy-open top requires no tools for re-lamping.
• Optional passive, non-inductive control provides near-unity power factors on all regulator steps.
• Optional Herculens panels available in Size 1 & 2.

Our L-858 taxiway guidance signs are manufactured in the USA with the patented D-Lux design, the best modular design in airfield signage. Each module of a D-Lux sign is mounted on an evenly spaced pair of legs. The D-Lux slip flanges hold the legs secure with almost no gap in the assembly. Environmental forces are shared by the legs and cabinet, and not concentrated on the hardware.

On a D-Lux, each rounded face is made from expertly formed acrylic. Size 1 and 2 signs can be fitted with the optional Herculens panel, which is CNC machined from 3/8" thick acrylic. The Herculens is factory installed on our Size 3 D-Lux, allowing the sign to shed jet blast without the use of bothersome flimsy plastic internal bracing or gimmicky cabinet "upgrades" employed by others.

Connecting the legend panels are translucent panel joints, which are welded together with adhesive and then additionally reinforced with stainless steel hardware.

Every D-Lux module features a top that is designed to easily guide the top edge of panels into place when it is replaced after re-lamping, and is fixed to the sign with two turn fasteners. No tools are required for re-lamping. The D-Lux uses familiar and inexpensive 6.6A 45W lamps, either quartz or incandescent. Configurations using miniature 12v 20w lamps are also available.

The D-Lux base model brightness controls use familiar technology that has been proven for years in the field. Better, the D-Lux also features a Style U power control system as an option - a passive, non-inductive design that exhibits near-unity power factors on all regulator steps.
