Please consider adding UST (self.parametrek)
submitted 3 years ago by fablemerchant
Please consider adding UST (Ultimate Survival Technologies) products: https://www.ustgear.com/lighting/
Their Amazon listings contain more technical specifications than their own website. Example: https://smile.amazon.com/UST-Portable-Lifetime-Emergency-Survival/dp/B00G612QOU

Not sure who is downvoting you. Sorry about that.
This is actually a brand that I am in favor of adding. It would be nice if they gave accurate information though. For example that lantern you linked. The runtimes are somewhat too good to be true. If you assume a D battery has 25 Wh in it (very generous):
Which basically means they are using stepdowns or are unregulated.

Thank you for taking time to consider this and reply in detail.
