| Color | Blue |
| Brightness | 4000 lumens |

| Best for | Campers and emergency kits that want a hands-free, waterproof lantern with adjustable brightness |
Product Overview
iodoo builds this as a dual flashlight and lantern, rated 4000 lumens at 30W, aimed at camping, emergencies and hurricane preparedness where an IPX5 waterproof rating matters. The hook and magnet base is built for hanging the light upside down over a tent or workspace to spread light across a wider area hands-free.
Worth flagging: the feature text states a 180 day replacement or risk-free refund warranty, while the separate manufacturer warranty field for this listing states 90 days. The two figures conflict, so it is worth confirming the actual warranty term with the seller before relying on either number.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
30W light engine for a clear view in dark environments.
Built for extreme weather, camping and emergency use.
Fully encapsulated pack removes incompatible-battery replacement risk.
Hangs upside down for hands-free, wide-area lighting.
Short press adjusts brightness, long press switches to flash or SOS mode.
Design and Build Quality
The light carries a built-in, fully encapsulated battery pack that cannot be swapped out separately. iodoo states this design removes the safety risk of someone fitting an incompatible replacement battery, though it also means the light stops working outright if that sealed battery eventually fails.
Mounting is handled through a hook plus a magnet on the base, letting the lantern hang upside down for wider-area lighting. iodoo's own instructions note checking that the magnetic hold is firm before relying on it, to prevent the light from falling.
Performance in Everyday Use
Output is rated at 4000 lumens from a 30W light engine, with a short press of the switch adjusting brightness and a long press switching into flash or SOS mode for signaling.
The IPX5 waterproof rating is positioned for extreme weather use, including emergency and hurricane scenarios, rather than light drizzle alone.
