Why choose a local IR LEDs supplier you can trust
When your project depends on near-infrared illumination - cameras, night-vision prototypes, proximity sensing or remote controls - waiting weeks for parts kills momentum. Communica offers practical advantages that matter: accessible stock across branches, VAT invoicing for institutions, and experienced staff who advise on part fit and drive circuits so your build works first time. For campus teams and small production runs, that translates to fewer procurement headaches and faster iteration.
Stock depth and brand coverage
We stock common emitter packages, high-power IR LEDs, and maker-friendly modules from brands you recognise. Browse related ranges on our Shop by Category and see brand options via Shop by Brand.
Local logistics that reduce lead time
Order online or reserve stock and collect from Samrand, Pretoria (CBD) or Cape Town branches - details on hours and collection at our Samrand, Pretoria (CBD). For academic purchases we provide VAT invoices and can support departmental quoting for bulk orders.
Key specification callouts - pick the right IR LED
Not all IR LEDs are interchangeable. Choose by wavelength, radiant intensity, viewing angle and forward current. Below is a compact spec comparison for typical project choices so you can decide faster at checkout.
| Type | Wavelength (nm) | Typical Vf (V) | Radiant intensity | Use case |
|---|---|---|---|---|
| Standard 940nm 3mm | 940 | 1.2 - 1.6 | 0.5 - 5 mW/sr | Proximity sensing, IR remote less visible |
| High-power 850nm SMD | 850 | 1.4 - 1.8 | 50 - 500 mW/sr | Night-vision illumination, cameras |
| Wide-angle emitter | 850 - 940 | 1.2 - 1.6 | Lower intensity, wide beam | Close-range image uniformity |
Compatibility guidance and accessories
Match LED wavelength to your sensor/camera sensitivity (850nm is brighter on many CMOS sensors; 940nm is less visible to the eye). Add resistors, constant-current drivers or IR LED arrays for even illumination. You can explore full product ranges on our All Products index.
Specification examples you can use immediately
Two quick specs to copy into requests or quotes: 1) High-power IR array: 850nm, 1W/ch, 350mA per LED, SMD5050 package; 2) Discrete emitter: 940nm 5mm through-hole, If max 50mA, viewing angle 20°. Include these lines when you contact us so our team can check local stock and recommend bundles.
