Here is what I purchased 8 months ago. Sunlight without the UV, 660 and Near Infrared at 850nm...much cheaper that the unit on site here, not as convenient to "wear"...i must admit!
I've been using smaller Red LED units now for years (from the LEDMAN, good fellow to do business with for 12 years...)... the unit below is very powerful and I feel it's useful....was using InfraRed in the 60's for Martial Arts injuries....I'm not young and need special help as here... https://www.alibaba.com/product-detail/HHE-2020-Led-Therapy-Light-300w_62460319980.html?spm=a2700.themePage.5238101000611.17.4f345d28ZwRC3W In SILvation....Douglas H in Oz
