21W 24VDC Rigid LED Light Bar for Tension Fabric Light Boxes

The Rigid LED Light Bar, also called Edge-lit LED Module or strip, is specially designed and produced by Lumening for tension fabric light box signs

This Light Bar is to be installed along the inner sides of both single-sided and double-sided fabric light boxes. Equipped with 7 high-power LEDs from CREE-LED, leader of the industry, combined with high transmittance concave optics, the bar can brightly and spotlessly illuminate your light boxes.

All Lumening products are fully customizable to best fit your light boxes and signs.


Product features:

Quality Light source: This 21W Rigid LED light bar uses 7 pieces of CREE XLamp High Power LED to deliver the highest lighting-class performance in the industry. They are long-lasting, highly reliable and energy-efficient. Color temperatures ranging from warm white to cold white are available to choose from.

Longer lighting distance for wider light boxes: Redirected by high-transmittance PMMA optics, light from the LEDs is bound within the beaming angles of 9 degrees and 50 degrees perpendicularly, when lighting across 2 opposite sides, This light bar is able to brightly and evenly illuminate 100 cm to 250 cm of light box fabric with no white spots and shadows.

Great Thermal dissipation: High quality Aluminum PCB effectively conducts heat away from the LEDs, creating an ideal working condition for the LEDs and other electronic components over running hours.

Ideal Driving method: This rigid LED light bar comes with an on-board constant current power unit that feeds the LEDs with fine-tuned and steady amps, optimizing the LEDs over all performance. The light bar itself is driven by 24 Volt Direct Current power supply.

Easy Installation: This LED bar is designed to install along the inner side of the light box’ aluminum frame by means of screws and nuts or heat-conducting adhesive tape that requires little professional skill.

Simple connection: Connection between light bars is plug and play with no restriction of polarity, completely straightforward and worry-free.

Dimmable: This light bar is dimmable with PWM method.

Cuttable: This product is cuttable from around the middle to fit various lengths of light boxes.

Fully tested: Every bar is a survivor from thorough and harsh aging test before shipping. Good quality is ensured.

Energy-saving: Power consumption of the product is up to 75% lower than conventional light box lighting with fluorescent tubes.
