Wall-Mounted Signal Tower Optimized for Industrial Environments
Audible and Visual Signals in One Unit – A Space-Saving Warning Solution
Warning systems for industrial safety are no longer limited to basic functionality. Today, they are expected to offer installation convenience, space efficiency, and multifunctionality.
To meet these on-site demands, Qlight Co., Ltd. introduces the wall-mounted steady/flashing LED tower lamp, the QWTD Series.
With a slim Ø70 mm design, the QWTD provides up to 5 tiers of visual signals and 5 selectable sound channels simultaneously. Its wall-mountable structure makes it ideal for installation on equipment exteriors, control panel sides, and other confined spaces.
Key Features
1. Integrated Audible & Visual Signaling Design
Selectable 5 sounds out of 20 built-in tones
(Warning tones, special alarms, melodies, alerts, etc.)
Sound output of 85 dB at 1 meter, ensuring effective signal delivery even in wide areas
Up to 5 light tiers with multiple color combinations
(Red, Amber, Green, Blue, White)
Steady/Flashing mode selectable (Models: QWTDL / QWTDLF)
2. Easy Installation & Wiring – Wall-Mounted Design
Low-profile structure minimizes protrusion, reducing risk of external impact or damage
Sliding bracket system allows quick and secure installation
Side lens structure provides excellent horizontal visibility
3. Environmental Durability & International Certifications
Operating temperature range: -30°C to +50°C
Protection rating: IP54 (suitable for indoor or dust-protected environments)
CE certified (DC12V / DC24V models)
RoHS compliant and manufactured through eco-friendly processes
Recommended Applications
Machine tool status indication (Run / Standby / Fault / Maintenance)
Visual signaling for automated production lines
Process visualization in smart factory environments
Worker safety management and warning systems
Practical Value for Customers
“If complex warning light installation and wiring are a burden, QWTD is the simplest alternative.”
Unlike conventional top-mounted tower lamps, the QWTD is designed primarily for wall mounting, allowing immediate installation without equipment modification. In addition, various sound tones and color combinations help maintain visual consistency across industrial sites.
“Machine tool performance is proven through machining — trust is completed through visible signals.”
QWTD – The Clearest Way to Express Your Process Status.
