Our Verdict

The Black Diamond Moji is a nifty little lantern for camping adventures when you want to light up a tent for one or two people. It's compact, relatively lightweight and easy to use. Because it fits easily into a backpack water bottle pocket, it's a good addition to a weekend backpacker's kit. It's not quite as versatile as some of its counterparts, but it delivers solid performance as a durable, reliable lantern. It's about as straightforward as a lantern can get; there really just aren't a lot of moving parts on this thing. Maybe best of all, it comes at an affordable price.

Our Analysis and Test Results

The Black Diamond Moji outshines some of its compact competitors. It's bright for its small size and very easy to use. It's not going to knock your socks off if you're trying to light a large space, but it's a nice choice for tent time reading or playing cards with a friend.

Performance Comparison

This compact lantern has easily accessible batteries  while remaining highly water resistant. A standard headlamp for scale.

At 100 lumens, the Moji is not nearly as bright as some other lanterns that we tested, but we were still able to do most everything we needed to. Its lowest setting has a shine radius of about 18 feet, while its brightest setting reached the corners of a 15' x 25' room. We preferred to use it in our tent at night to play cards and read.

We like the light quality of the Moji more than other lights with blue/white LEDs. It's a little warmer, and the opaque plastic cover diffuses it a little better. This lantern also has a light 'memory', meaning that if you turn it off and turn it on again, it will remain at the same brightness until you dim or brighten it.

At top  the Moji lights up a 2-person tent and a wide area around it. On bottom  the Luci Outdoor 2.0 lights up the same tent  but with a much smaller additional radius.

The Moji is durable, primarily because there really just aren't very many parts to break. It has a simple, elegant form that stands up well to regular use and being carried around in a bag all day. The plastic light cover could certainly get dinged up if it was dropped on an asphalt surface, but it wouldn't impact the overall performance of the product.

It has an advertised Ingress Protection rating of 4 (IPX4), which means it should stand up to splashing water coming at it from any direction. We left ours out in the rain for several hours and even dunked it in a river just to make sure — it still works great; the light turns on, with no obvious water seepage or damage. The X indicates that it hasn't officially been rated for solid particle resistance, but the seal on the battery cover keeps out the regular "dirt-y-ness" of a campsite.


The Moji is almost as basic as a lantern can get. Press the power button once to turn it on, again to turn it off, and hold it down in between to either dim or brighten it. It comes with opposed metal hooks on top so it can easily be attached to a carabiner, or hung from a clothesline. The logo on top is also reflective, which makes it easier to spot at night.

Because of how compact it is, if you don't have anywhere to hang the Moji, you are out of luck. It has no stand or legs, so resting it light side down on the ground or a table means that almost none of the light shines where you need it. Flipping it over so that the light is shining straight up makes it uncomfortable to look at and casts heavy 'telling a ghost story' shadows on people and objects around it. It does have small rubber nubs on the cap to rest on, but we wouldn't bat an eye if they weren't there.

The Moji lit up in the foreground with its larger sibling  the Apollo  behind it. Both come with opposing metal hooks for easy hanging.

The Moji also comes in five colors (vibrant orange, process blue, graphite, dark berry, and fern) if that's your thing.

Ease of Use

This lantern is very easy to use. Unscrew the rubberized top, insert the required three AAA batteries and you're good to go. Its single power button is textured, so it's easy to locate on the lantern in the dark. Beyond that, there's not a whole lot else to 'use' on this thing, which may be ideal for the purists among us.


At 4.3 ounces (with batteries!), it's one of the most compact lights in this review. It's 2 ¼ inches in height, with a diameter of 2 ¾ inches, also making it one of the most compact lanterns we tested. We love that it fits in the palm of a hand, so it can easily stand in for a flashlight in a pinch.


We think the Moji is a really solid value. Not only is it one of the least expensive lanterns in this review, but it is durable and should last for many, many years of good use. It is also less expensive than headlamps of equivalent quality, so it's worth a look if you are choosing between one or the other.


The Moji continues what we have come to expect from the Black Diamond line. Though we would definitely opt for something larger and more powerful if you are looking for a single campsite lantern, we really have no major complaints. In the Moji, you get a compact, lightweight, bright-enough lantern.
