In the Box

I bought the Leschi from Amazon. Here’s what I got:

• The lantern flashlight
• A user guide

Power Source

• Battery: 1 x AAnot included

The compartment is at the bottom. Unscrew it, drop the battery in, and screw it back on.

Light Modes

One button does everything. A firm press turns it on and off, and a light press cycles the modes.

• Modes: Strobe → Low → High

The memory setting is a strange one. Turn it off on Low and it comes back on High. Turn it off on High and it comes back on Strobe. It always jumps one mode ahead, which isn’t very useful.

Run Times

I timed each mode on Eneloop batteries that are already a few years old. I stopped the clock once the light started dimming and flickering, so the second column is how much longer it kept going in that state.

Mode	Run time	Then dim & flickering
High	4 hrs	+2.5 hrs
Low	11 hrs	+2 hrs
Strobe	3 hrs	+2.5 hrs

Lumen Output (Lantern)

I set the Leschi to its lantern setting and read each mode with a lux meter at a fixed distance.

• High: 125 lumens
• Low: 33 lumens

Lumen Output (Flashlight)

UCO publishes no flashlight figure, so I used a ceiling bounce test instead.

• High: 517 lumens21 lux – ceiling bounce test
• Low: 49 lumens2 lux – ceiling bounce test

Note: A ceiling bounce gives only a rough estimate, not a lab measurement. Mine was taken under a 9.2ft ceiling, over 265.12 sq ft of floor area.

Shine Distance (Lantern)

I set the lantern on a pole, then backed away with the lux meter until it read zero, and measured back to the lantern.

• High: 2.58ft
• Low: 1.94ft

Beam Distance (Flashlight)

Same method on a trail, with the flashlight on the ground.

• High: 48.2ft
• Low: 24.1ft

UCO markets 279ft on high. My meter cuts off at a zero-lumen reading and theirs measures out to full-moon lighting, so the two numbers aren’t describing the same thing.

Hook & Strap

• Strap: shock-cord
• Fits around: up to 1.5in diameter

IP Rating

• Tested: IPX5moderate rain

I left it out in 25 minutes of moderate to heavy rain, then ran every mode again.

Everything still worked and the battery compartment stayed dry. Only the lantern housing got damp.

Drop Testing

It takes drops from hand height and holds up fine.

Materials

• Body & lighting housing: high-grade plastic
• Battery housing: aluminum

Warranty

• Warranty: 1 year

Portability

• Weight (with battery): 2.57oz
• Weight (no battery): 1.62oz
• Packed size: 3.9 x 1.25in
• Extended length: 5.15in

Pros, Cons & Recommendations

Now, what are the pros and cons, and would I recommend the UCO Leschi LED Lantern?

Pro #1 – Inexpensive

It’s a very inexpensive lantern flashlight, about as cheap as a 2-in-1 gets.

Pro #2 – Portable

At 2.57oz it’s small, light, and it hangs off almost anything.

Pro #3 – Good beam distance

48.2ft on high is genuinely impressive for a flashlight this size, and it was more than enough to camp with.

Con #1 – Low shine distance

As a lantern it lights up a 1 to 2-person tent at most, and High is barely better than Low.

Con #2 – Not feature-rich

At this price a lot is missing. There’s:

• No proper memory setting
• No battery indicator lights
• No mobile charging
• No magnetic base

Con #3 – Inconsistent run-times

The run-times were inconsistent. Sometimes they came in under what I measured here, sometimes over, which made this testing difficult to pin down.

Con #4 – Inconsistent high brightness

Those lumen figures are on completely fresh batteries. About an hour in, brightness drops by 30% or more, down to roughly 75 lumens, and it keeps falling from there. Even at full charge, High flickers occasionally.

Bonus – MUST Read!

I measured every number on this page myself.
