What owners report

Sofirn LT1/4 sources reviewed

The LT1 is the camping lantern enthusiasts actually recommend, and the reason is colour temperature mixing: it ramps continuously from very warm to cool white, with a separate red channel, all under Anduril. Being able to dial a warm, low, red-shifted light in a tent — and a bright neutral one for cooking — is what separates it from every generic lantern.

Build quality is good, with thick even anodising and no sharp edges. The complaints are small and physical: the carry bail is squeaky and gritty in use, and the bottom cap threads are awkward to start because of a large, stiff spring. It runs on four 18650s for genuinely long runtime. Note that the later LT1S dropped Anduril for a Sofirn-designed interface, which reviewers regard as a downgrade from the original's main strength.

Consistently praised

Continuously variable colour temperature from very warm to cool, plus a red channel
Full Anduril, which is what makes the CCT mixing worth having
Four 18650s give genuinely long runtime
Good build: thick even anodising, no sharp edges
The warm end preserves dark adaptation far better than a generic cool-white lantern

Common complaints

The carry bail is squeaky and gritty in use
The bottom cap is awkward to start on its threads because of a big stiff spring
Four cells to buy, charge and keep matched
Bulkier than a collapsible lantern for backpacking
The later LT1S traded Anduril for an in-house UI — a step back, not forward

Questions people ask

Why does colour temperature mixing matter on a lantern?: A tent at night wants warm, dim light that doesn't wreck your night vision or attract insects as strongly; cooking or repairs want neutral white. One lantern doing both, on a slider, is genuinely more useful than two fixed ones.
LT1 or LT1S?: The LT1 keeps Anduril and takes four cells for long runtime. The LT1S is smaller, collapsible and takes one cell, but dropped Anduril. Choose the LT1 for capability, the LT1S for packability.
How long does it run?: On four 18650s at a usable indoor level, comfortably a full weekend of evenings. Turbo drains it far faster, but a lantern is rarely a turbo device.
Does it need all four cells?: It's designed around four and they should be the same brand, age and charge state — mixing cells in a multi-cell light drives the weakest one into over-discharge.
