gray lantern

Brightness ranges from about 44 lumens up to around 1,000 lumens. Reported runtimes commonly fall around 20–24 hours, varying by model and power source.

Many models offer water- or weather-resistance; some are described as waterproof (IPX4) or as water- and heat-resistant for outdoor use.

Gray lanterns include LED-based lighting (COB and other LEDs), traditional kerosene or lamp-oil flames, and decorative candle-style lanterns with no electrical light source.

Solar decorative lanterns are described as having a solar panel for charging; some models list a 1 AA alkaline battery as optional or included for backup power.

Many portable gray lanterns include foldaway or non-slip handles, built-in hanger rings, and collapsible designs for easier carrying, hanging, and storage.
