Product Information

This 5050 Double Row LED Strip Light emits bright 660nm red light, the 660nm wavelength is a red light and presents a deep red light performance. 660nm is used in red light therapy, a photobiomodulation or LED light therapy that safely and painlessly treats the skin and body, and has many health benefits for human beings.

The 660nm wavelength emitted by the 660nm led strip is very effective in red light therapy because it is compatible with human cells, close to the resonance frequency of cellular tissues, and is the best single wavelength for stimulating and treating damaged or abnormal human cellular tissues. 

The double rows of 5050 SMD LEDs enhance the brightness performance of this 660nm red led strip, you don't have to spend money on expensive red light therapy at beauty salons or medical clinics anymore, with this deep red 660nm led strip, you can DIY your red light therapy space at home. 

High power red light 660nm led strip will generate heat, it is recommended to use aluminum profiles as mounting channels.

Exceptional 660nm peak—Perfect for the flowering stage!

I've been looking for a high-intensity 660nm source to supplement my indoor grow setup during the bloom phase. Most "red" strips are just standard 620-630nm, but you can really tell the difference with this Deep Red 660nm wavelength. The double-row design provides a massive boost in PAR output compared to single-row strips. I’ve noticed a significant improvement in flower density since adding these to my racks. The build quality of the 5050 chips is robust, and the copper PCB handles the heat well for a strip this powerful. If you’re serious about your spectrum and need high-output red light, this is the professional way to do it.
