Red LED Modules
Maximum Visibility and Attention-Grabbing Power
Red is the colour that best captures human attention. Visual perception studies confirm that our peripheral vision detects red before any other tone, explaining its universal use in stop signs, traffic lights and alerts of all kinds. That is why it remains the first choice for emergency signage, commercial offers and signs that need to stand out from their surroundings.
Technical Characteristics of Red LED
Our modules use LED chips with a wavelength around 620-625nm, producing an intense, pure and highly saturated red. This tone works especially well in low ambient light conditions, where its contrast with the environment achieves maximum visual impact.
The luminous efficiency of red LEDs is naturally high, as the conversion of electrical energy to red light is more direct than for other colours. This translates into lower consumption for the same perceived intensity, benefiting both your budget and the module's lifespan.
- Excellent performance in night signage and low-light conditions
- Low consumption compared to traditional neon or filtered incandescent bulbs
- Lifespan exceeding 50,000 hours under normal operating conditions
- Multiple configurations of power, LED count and beam angle
- Stable colour tone maintained throughout the entire lifespan
Common Uses in Signage
Animated LED pharmacy crosses, illuminated "OPEN/CLOSED" signs, emergency exit signage and discount and promotion signs are classic applications where red LED demonstrates its full potential. In hospitality, bars, restaurants and nightlife establishments regularly use this colour to create atmosphere.
The retail sector leverages red to highlight offers and sales, taking advantage of the colour's psychological association with urgency and opportunity. In industrial settings, it is used for safety signage and marking of restricted areas.
Combine red modules with green modules to create bicolour effects in pharmacy crosses or alternating signage. If you need programmable colour changes, see our RGB range with DMX or WiFi control.
Comparison: Red LED Module 12V vs 24V
Both voltages emit the same wavelength (620–630 nm) and dissipate the same power per module. The real difference is the maximum run length without noticeable voltage drop:
| Feature | Red 12V | Red 24V |
|---|---|---|
| Recommended max run | Up to 20 m per line | Up to 40 m per line |
| Voltage drop | High beyond 15 m | Minimal even at 30 m |
| Pharmacy / emergency cross | 60×60 and 80×80 cm crosses | 100×100 cm or larger |
| Channel letters | Letters up to 40 cm tall | Large letters and continuous facades |
| Power supply | 12VDC IP67 driver | 24VDC IP67 driver |
| Consumption per module | 0.72 W | 0.72 W |
| Wavelength | 620–630 nm | 620–630 nm |
| Ideal use | Small signs, indoor signage | Facades, large crosses, outdoor retail |

How Many Red Modules per m² and per Sign
Reference density for channel letters and standard signage with 3 mm opal acrylic diffuser: 100 modules per m².
| Format | Surface | Red modules approx. | Recommended voltage |
|---|---|---|---|
| Emergency cross 60×60 cm | 0.36 m² | ~36 modules | 12V |
| Channel letter sign 80×80 cm | 0.64 m² | ~64 modules | 12V |
| Cross / sign 100×100 cm | 1.00 m² | ~100 modules | 24V (lower drop) |
| Facade 120×120 cm or larger | 1.44 m²+ | 144 modules min., segmented supply | 24V mandatory |
With thick opal acrylics (5 mm or more), increase quantity by 15–20 % to avoid visible hot spots.
