Thats the most expensive flash light I've ever seen!!

I've used red filters for many years in astronomy as it preserves night vision. I now use red led coin cell lights ($8) as they are a truer red and plenty bright for what I do. I wear a lanyard around my neck when camping that has a whistle compass, white coin cell light, and red coin cell light. Inova lights are my personal favorites. Anything more that those are overkill for my use.
