5mm “through Hole” diodes have an incredibly narrow distribution of light, mostly commonly 20-30 degree angles creating more heat because the epoxy casing acts as a focusing lens.

This equals fewer cells receiving light during a session. A narrow spread of light may be beneficial in some purposes such as treatments that is being performed at long distances, but when we are considering PBM pads, a narrow pin-point spread is not ideal. The “through holes” are closer to a laser diode spread of light than SMD.

Another negative of the “through-hole” is that because they are only a single frequency, most manufacture’s alternate 850 NIR and 630 Red every other row.

This coupled with the narrow spread of the “through-hole” light creates significant coverage voids into the tissue.

SMD’s on the other hand house multiple diodes in each chipset, allowing for a combination of wavelengths being able to be emitted from a single chip set casing.

This is beneficial over an entire pad, as both 850nm and 630nm wavelengths are in each chipset and are evenly distributed throughout the entirety of the pad and are devoid of dead spots of the polychromatic light.

So, our 221 chipsets are actually 442 highly efficient and powerful diodes.

Neurocare Pro’s SMD’s have a much larger spread, with a light emitting angle of 120-degrees (versus 20-degrees of 5mm LEDs).

The bigger the spread, the bigger the target area is exposed to beneficial photobiomodualtion light, which equates for a better treatment and thus, better results.

SMD omits less heat and allows a higher power output and thus more joules entering the cells. In further contrast, the light from an SMD is very diffused, which makes them more suitable for medical applications that require a wide beam angle

The SMD are flat and reset diodes. Neurocare Systems takes great care to make sure that we also deliver added comfort on our boot systems for patients during use.

Our competitors will have you believe that the older “through hole” technology featuring protruding diodes is by design so when these diodes stick into your patients’ tissue and bone, it is closer to the effected tissue and yields better results.

LED PBM penetration studies strongly contradict this nonsense. In fact, the number one complaint from patients is the uncomfortable of protruding diodes, especially if they have edema or other tissue sensitivity.
