Hi I want to build a near infrared panel of 830Nm bulbs that can be handheld to self treat my arthritis
Basically something like this: https://redlightman.com/product/infrared-mini-830/ is what I am trying to create, but I simply cannot afford the £100 they are talking about!
I found these https://uk.rs-online.com/web/p/ir-leds/6997685/ and was wondering if these could be used e.g. get 50 of these and somehow embedd them into a circuit board + housing
Any tips hugely appreciated
