The panel shines brightly. Approximately like a 100-watt infrared heating lamp used for warming chicks. All LEDs are working properly. I removed the panel from an old camera that did not have an IR filter. The light from the 850nm LEDs is perfectly visible on such a camera. Especially if you cover the 660nm LEDs with paper (see photo).
The product seems to be good quality very light weight. The red light leds are very bright and strong, so must use eye protection. Can’t wait to use it and hopefully see some results.
Lights appear to be good quality this is based on recovery rate, reduced inflammation and pain in joints. I've recommended this product to several of my martial arts students and they too are getting good results similar to my own. The panels are good but the mounting clips and wires are basically useless, you need to figure out your own system for mounting or preventing them falling over.
It arrived super fast. It has met all my expectations. I have been using it for a week and I have noticed some improvement in my abdominal wall and in the information of my abdomen. I place it directly on my skin, that is, without clothing, at a distance of 30 cm for about 20 minutes every day. Protecting myself with glasses. Just as indicated by the girl in the manufacturer's video. The only thing I didn't like is that the instructions come in English, but I took a photo and passed it to the artificial intelligence, and it translated it and explained everything very well.
The panel is very good, it seems nice and I've started to notice sensations like more fluidity in the blood.
