Innovation en alarme & signal, systèmes et solutions d'affichage d'état visuels et sonores - Qlight

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.

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.

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.

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.

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.

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.

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.

A. The QELT-UL is a non-waterproof model, designed for protected environments such as inside distribution panels or control cabinets.

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.

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.

The QELT-220-UL series combines high illumination, simplified wiring, multiple length options, and the reliability of UL(RU) certification.

If you are looking for a proven LED lighting solution designed specifically for distribution panels, suitable not only for domestic equipment but also for export-oriented projects, the QELT-220-UL series is a practical and reliable choice.
