Just curious! If someone has received a PM from lightdoctor, just how much are you required to spend upfront to review the light? What does it look like. What batteries are required?

I doubt if I would be interested as I have been using a 60 LED, 3 mode (5, 17, 60 LED), 3X AAA or 1X 18650 battery, ~5 oz umbrella tent light that I bought from Banggood more than two years ago. It meets all my needs for a tent light. If there is no loop in the tent to attach it at the peak you can just use a small binder clip to attach the light hook to the tent seam. The price for the same light has dropped so much you can now buy them on eBay for $6 or less. The price is hard to beat for the results you get.
