The lantern for people who hate lanterns
The Black Diamond Moji strips the lantern down to its essentials: a frosted globe the size of a hockey puck, one TriplePower LED, and a single dimming switch. It puts out up to 100 lumens, runs on three AAA batteries for up to 70 hours on its lowest setting, and weighs 4.3 ounces with batteries. There's no app, no solar panel, no power bank, no color modes. What there is: the simplest possible way to light a tent, a table, or a dark hallway, from a climbing brand that knows what gear abuse looks like.
One switch, infinite dimming, zero learning curve
The Moji's signature feature is its dimmer switch — not stepped modes, but a smooth slider that lets you dial in exactly the brightness you want, from a soft nightlight glow to the full 100 lumens. The frosted globe spreads that light evenly in all directions with no harsh glare, which is exactly what you want in a small room. A collapsible double-hook loop folds out to hang it from a tent loop or a branch, and folds flat for packing. It is, in the best sense, boring: turn it on, set the brightness, hang it up.
The honest trade-offs of AAA simplicity
Running on three AAA batteries (not included) is both the Moji's virtue and its limit. On the plus side, AAAs are everywhere — you can resupply at any gas station, and the batteries hold their charge on the shelf for years, making this a true stow-and-forget emergency light. On the minus side, runtime on high is about 10 hours, so it's a modest-brightness lantern, not a workhorse. There's also no rechargeable option in this model (its bigger sibling, the Moji+, adds Dual-Fuel battery support and 200 lumens). Retailer figures conflict slightly on max burn time — 70 hours on the lowest setting per some listings, up to 100 hours per others — so treat the extreme end as best case.
Who it's for, and who should skip it
Buy it for the tent, the nightstand, the kids' room, or a second lantern in every car. It's the right call when you want dead-simple light with no charging logistics and you trust shelf-stable AAAs in a drawer.
Skip it if you need serious output or phone charging — the Moji tops out at 100 lumens and feeds nothing else. For a primary blackout lantern, the Energizer WeatheReady 360 Pro gives you five times the brightness and a USB port.

Frequently asked questions
Are the AAA batteries included? No — plan to add your own. Alkaline AAAs are ideal for emergency storage since they hold a charge on the shelf for years; rechargeable AAAs work fine for regular camping use.
How long do batteries last on high? About 10 hours per retailer specs. The dimmer switch is the real endurance trick — dial it down and you stretch into multi-day territory.
Can it survive rain? It's IPX4-rated, meaning splash-proof from any angle. Light rain and splashes are fine; don't submerge it.
Should I get the Moji+ instead? If you want more: the Moji+ offers 200 lumens, Dual-Fuel battery compatibility, and color/strobe modes — at a higher price. The standard Moji wins on simplicity and cost.
Verdict
The Moji is the anti-gadget lantern, and that's its whole appeal: a dimmer switch, a frosted globe, and 100 honest lumens from batteries you can buy anywhere. It won't win a spec war, but it will still be working when the clever ones are dead. Check the current price on Amazon: View on Amazon
