Features of 2LEDs High Efficiency LED Modules

1. High-efficiency 2-LED configuration

The YS-MA2321 integrates two SMD2835 LEDs into each module and delivers up to 122 lm from only 0.72W, providing a higher light output per module while maintaining a luminous efficacy of up to 170 lm/W.

2. 170 lm/W high luminous efficacy

Designed for energy-conscious signage applications, the module combines high-output SMD2835 LEDs with an efficient optical design to produce strong illumination without requiring excessive electrical power.

3. Constant-current design for stable output

The optical characteristics of the MA2321 make it suitable for relatively shallow and medium-depth illuminated signs, including light boxes and channel letters with approximately 4–16cm internal depth.

4. Flexible module cascading

The standard cascade quantity reaches 20 modules. Depending on the power supply arrangement, up to 20 modules with one-side power supply or 40 modules with two-side power supply can be connected, giving sign manufacturers flexibility when planning different installation sizes.

2LEDs High Efficiency LED Modules Layout Density Guidelines

These tested layout density guidelines apply to our High Efficiency LED Modules for backlit sign and light box builds. Use the table below to find recommended LED spacing, units per square meter, and expected surface illuminance based on your light box thickness, so you can design a uniform, well-lit sign with accurate material and cost planning.

Light Box Thickness(mm)	LED Spacing(mm)	Installation density(PCS/m²)	Surface illumination(Lux)
40	80*60	208	7000~8000
60	100*80	125	4000~5000
80	140*120	60	2000~2500
100	180*160	35	1200~1500
130	200*200	25	700~900
160	200*200	25	700~900

Remark:
(1) The above lighting data is tested by this module 6000K color temperature
(2) The thickness of the acrylic whiteboard is 2.5mm, and the light transmittance is 54.4%;
(3) The luminance of this example is the lowest luminance value under the condition that the thickness of the surface is uniform;
(4) The above data is for reference only;

Recommended Applications for 2LEDs High Efficiency LED Modules

1. Illuminated light boxes

Suitable for backlighting light boxes with approximately 4–16cm depth, providing broad light distribution across the sign face while allowing installers to arrange modules according to the dimensions of the box.

2. Channel letter signage

The 2LEDs configuration provides a higher light output per module for illuminated channel letters, helping sign manufacturers achieve the required brightness with an appropriate number of modules.

3. Medium-size illuminated signage projects
