Hello,
I wanted to ask if you could help me with a power supply problem?
I have a visor light therapy device (for use above the eyes) the battery of which is defective. (Please ignore the arrows in the picture). This is the second time that the battery broke (second device). I have opened the device now, and as a test, I connected two AAA batteries (1.5V) to see whether it would otherwise still work, and indeed the LEDs lit up as usual.
I would like to either connect power directly via an adapter OR use a battery. Because of the Zebralight, I will soon either buy an Eizfan Lux S4 or (most likely) a Vapcell S4 plus, if that is relevant as information.
Since I am not familiar with electronics, it would be great if someone could tell me
- which voltage I should set for an adapter that I would then use for direct power supply
- which battery I should be using if I use a battery — it is important to me that it is protected and as safe as possible.
- I would also like to carry the battery by cable in a different place than directly on the head / eye as a safety measure, if you could tell me what kind of cable would be suitable for this (1 meter) ….? I would be attach the battery/battery holder as a belt clip.
The device is the FeelBrightLight Visor Deluxe (or something like that). A “cheap Chinese device presumably ”designed by doctors Canada”, which still seems to me to be the best or one of the best considering alternatives. (luminette 3 / Re-timer / Pegasi 2 —— either blue / white instead of green, or light from below instead of above)
(I don’t want to destroy the electronics with too much voltage, or have too little light as a relult of too little voltage.)
Thank you a lot!
PS. The battery has been discarded of and the wires leading to the battery is where I attached the two AAA non-rechargeable batteries.
