Meeting Global Standards
QELT-220-UL (AC220V) Newly Obtains UL(RU) Certification
When opening a distribution panel, technicians often face the same challenges:
shadows, blind spots, fatigue, and small wiring mistakes.
In environments where inspection, replacement, and expansion tasks occur frequently, lighting is not just a convenience—it is a fundamental element that directly affects work quality and safety.
The QELT-UL series by Qlight is a LED lighting solution specifically designed for distribution panels, already meeting global safety standards through UL(RU) certification.
With the newly obtained UL(RU) certification for the AC220V specification, the QELT-220-UL can now be applied more broadly—not only for domestic control panels but also for export-oriented panels and projects requiring North American compliance.
Why UL(RU) Certification Matters
UL(RU) certification is one of the most recognized safety standards required for the North American market, verifying strict criteria such as:
· Electrical safety
· Insulation performance
· Withstand voltage standards
With this certification, the QELT-220-UL is no longer simply a panel light for domestic applications, but a distribution panel LED lighting solution designed to meet global engineering standards.
Key Advantages of the QELT-UL Series
1. Wide downward light distribution optimized for enclosed panels
Inside a distribution panel, what is needed is not light that spreads far outward, but light that spreads widely downward.
The QELT-UL series is designed to maximize downward illumination coverage, improving visibility within confined panel spaces and enabling safer and more efficient maintenance work.
2. Terminal Block Integrated Structure for Easy Wiring
When considering wiring organization after installation, ease of connection directly translates into cost efficiency on site.
The QELT-UL features an integrated terminal block (terminal box type) design, simplifying wiring work for users and reducing installation time.
3. Direct AC LED Control System | Minimizing External Power Supply Requirements
Reducing external power supply configuration, installation space, heat generation, and additional wiring allows for a much cleaner panel design.
The QELT-UL is designed to operate with direct AC voltage input, minimizing the need for a separate power supply unit.
4. Length Options to Match Panel Size and Installation Conditions (200 / 300 / 400 / 500 mm)
The QELT-UL series offers four length options (200 / 300 / 400 / 500 mm), allowing users to select the most appropriate model according to lighting coverage and panel installation conditions.
5. Detachable Mounting Bracket | Flexible Installation
Avoiding unnecessary rework—such as modifying panel holes due to mismatched mounting distances—greatly improves installation convenience.
The QELT-UL adopts a detachable mounting bracket design, allowing adjustment of mounting hole spacing for greater installation flexibility.

FAQ (Frequently Asked Questions)
Q1. Is this a waterproof product?
A. The QELT-UL is a non-waterproof model, designed for protected environments such as inside distribution panels or control cabinets.
Q2. How should I choose the appropriate length?
A. For larger panel working areas or panels with internal obstacles, a 300–500 mm model is recommended. Selection can be supported using luminous flux and illuminance data for each length option.
Q3. Is installation complicated?
A. Not at all. The terminal block integrated structure and detachable mounting bracket design provide flexibility in wiring and mounting, reducing the installation burden on site.
Recommended For
- Sites with frequent distribution panel inspection and maintenance
- Where regular inspections, component replacements, or expansion work are common, and clear visibility of the working area directly impacts safety and work quality.
- Customers who want to reduce terminal and labeling identification errors
- In environments where poor internal lighting makes it difficult to identify terminals and markings, leading to rewiring work or downtime.
- Panels with tight internal space
- Where installation and wiring become cumbersome due to limited panel space.
- Customers who prefer simple wiring structures
- Where shorter installation time and simpler wiring are preferred over additional power supplies or complex wiring systems.
- Projects with various panel sizes and installation conditions
- Where different panel specifications exist within the same project, requiring flexible length options (200 / 300 / 400 / 500 mm) for optimal installation.
- Projects requiring UL-related compliance (for export markets or North American applications)
- Where certification and regulatory compliance are critical, and the selection criteria must be clearly documented.
- Equipment managers who want to improve operator satisfaction and visibility
- Where operators often say, “The inside of the panel is always too dark when we open it.” and improvements in visibility and reduced fatigue are desired.
