Designs for Vision (DVI) LED DayLite light for surgical loupes

2017 LED DayLite light for surgical loupes made by Designs for Vision (DVI). Lightly used and still works great. I'm selling this because I recently bought a new pair of loupes with higher magnification along with a newer headlight so i don't need the old one anymore.

Of note - the set came with two charger packs but only one of them works (I tried replacing the battery but it still won't power the light). If you're savvy with electronics you might be able to salvage it.

Designer specs:
Lithium ion battery supply
Adjustable intensity ranging from 10% to 100%
2" light spot at 13" working distance with 9,500 footcandles
Correlated color temperature 5800 kelvin (K)
Battery life ~ 7 hrs (probably slightly less now although you can get replacements online for ~$40)

Set comes with:
Two power packs (only one working currently)
Two holsters
Desktop charger
Operation manual
Clip kit
Headlight cable
LED DayLite headlight with clip-on bracket
Loupes not included
