Features of DF50 & DF60 Series Backlighting Shutter Led Bar
1. Two Power Distribution Architectures for Different Project Requirements
The DF Series includes both DF50 and DF60 models to accommodate different commercial backlighting projects. The DF50 Series is ideal for standard advertising light boxes and retail displays, while the DF60 Series features a heavy-duty power distribution design for long cascade installations and oversized illuminated signage. This dual-series structure allows customers to select the most suitable solution based on project scale, installation distance and power distribution requirements.
2. Long Cascade Design Reduces Wiring Complexity
Unlike conventional LED light bars, the DF60 Series is engineered with a 14AWG high-current trunk cable, supporting up to 20A current capacity. This significantly reduces voltage drop during long-distance installations and minimizes the number of power injection points required. For large-format light boxes, fewer cable connections mean faster installation, cleaner wiring and lower maintenance costs throughout the project lifecycle.
3. Multiple Configurations for Flexible Light Box Design
ATo accommodate different cabinet sizes and illumination requirements, the DF Series offers multiple LED quantities, bar lengths and LED spacing options. Customers can choose between 100 mm or 150 mm LED spacing and 480 mm or 960 mm bar lengths, allowing designers to balance brightness, installation cost and lighting uniformity for virtually any light box project.
4. Fast and Flexible Installation
Designed with modular connectors, the LED bars can be connected quickly and securely. Their lightweight aluminum construction allows fast installation while reducing maintenance time for commercial lighting projects.
DF50 & DF60 Series Backlighting Shutter Led Bar Dimensions

The dimension structure of YS-DF50310-196 & YS-DF60310-196 LED Light bars is identical to the above drawing, with only two differences: total overall length extended to 960mm and upgraded to 12pcs 2835 LED beads per strip for higher brightness output.

DF50 & DF60 Series Backlighting Shutter Led Bar Wiring Diagram & Installation Guide
Installation for DF50 series LED Light Bar
1. the main line of this LED bar is 18AWG, and the maximum load current is 10A
2. When a single main line is connected to power supply (DC12V), maximum of 10pcs 12LEDs can be connected
3. This product uses two main lines, as long as keep one line can be lighted

Installation for DF60 series LED Light Bar
1. LED Spacing 100mm, Input voltage DC12V
2. 4pcs 300W power supply (suggest 300W power supply, so directly one main line to connect)
3. 80pcs led bar, the cascade length is 8 meters. (e.g. the light box thickness is over 80mm, led spacing is 150mm, 80pcs is a total of 12 meters)

1. LED Spacing 100mm, Input voltage DC24V
2. 4pcs 300W power supply (suggest 600W power supply, so directly one main line to connect)
3. 4 lines all are connected to the power supply, 160pcs led bar, the cascade length is 16 meters (e.g. the light box is over 80mm, the spacing is 150mm, 80pcs is a total of 24 meters)

Comparison of DF60 Series Long Cascade & DF50 Series Ordinary Cascade LED Bar
Both DF50 and DF60 shutter LED bars adopt stable DC12V constant voltage design for signage backlighting, the core difference lies in internal main wire specification and applicable cascading layout range to match different project demands.
1. DF50 Standard Cascade Version (18AWG main wire)
Equipped with 18AWG power wire, it is the ideal economical choice for conventional medium & small-sized channel letters and short indoor light boxes. It meets the basic layout needs of most regular commercial signage projects with moderate cascading length limit, bringing cost advantages for standard-size orders.
2. DF60 Long Cascade Version (14AWG thickened main wire)
Upgraded with thicker 14AWG heavy-load wire with higher current carrying capacity, which effectively reduces voltage drop during ultra-long series connection. This layout maintains consistent brightness across the whole oversized billboard, perfectly tailored for extra-long wall signage, airport and mall large-scale light box projects requiring extended wiring distance.
You can select the suitable series according to your actual light box total length, layout size and project budget.

Recommended Applications for DF50 & DF60 Series Backlighting Shutter Led Bar
1. SEG Fabric Light Boxes
The DF Series is specifically developed for SEG fabric light boxes, delivering bright, even illumination across large graphics while minimizing hotspots. Its modular design allows installers to quickly configure different light box sizes, making it an excellent solution for retail stores, shopping malls and branded interior displays.
2. Large Commercial Advertising Displays
For oversized advertising light boxes, maintaining consistent brightness across the entire display is critical. The DF60 long cascade series supports extended installations with reduced voltage drop, making it especially suitable for shopping centers, airports, subway stations and other commercial environments where large-format illuminated graphics are required.
3. Architectural Backlighting
4. Large-Scale Signage Projects
