I’m planning a custom setup with red and infrared LED strips, from 635 nm to 940 nm, for plants, health devices, and home security.
I’m trying to figure out:
Which wavelength works best for my application
Which LED type (SMD2835 vs 5050) fits different areas
How to combine strips for best results
For example, I’ve heard 660 + 730 nm is great for plants, and 850 + 940 nm is good for night vision.
Anyone here who’s done a similar custom setup? How did you choose the combination, placement, and type of strip? Would love to hear your tips or examples!
Thanks for sharing your setup plan — this is a great example of where a custom LED solution really makes sense.
In practice, the best wavelength and LED type usually depend on how each area is used. For plant applications, 660 nm red is commonly used for growth, while 730 nm far-red is added for flowering control or light-cycle adjustment, so that combination is a solid choice. For home security, 850 nm works well with most cameras due to higher sensitivity, and 940 nm is often selected when a more discreet, no-glow setup is preferred.
When it comes to LED type, SMD2835 is typically used in smaller or indoor areas where even light, lower power consumption, and long operating hours matter. SMD5050, with higher output, is better suited for spaces that need stronger coverage, such as greenhouses, outdoor zones, or areas with longer distances.
For mixed applications like yours, many users plan the setup by function: selecting the wavelength first, then choosing the LED type and spacing based on distance, run time, and heat management. Proper placement and control (timers or controllers) also play a big role in getting consistent results.
It’s good that you’re thinking about combinations and layout early on — that usually leads to a much smoother installation and better long-term performance.
