Goal Zero Lighthouse 600 review: a rechargeable room lantern with a crank for power outages

This is a research-based review, based on manufacturer specs and published data. We do not test products. Specs come from Goal Zero's Lighthouse 600 product page and FAQ, checked November 1, 2026. Safety guidance comes from the CDC.

A flashlight shows you a path; a lantern lets a family eat dinner, play cards and read. In an outage that runs past the first night, a good room light does a lot for morale and safety. It also replaces candles, which the CDC advises against when battery-powered light is available.

The Lighthouse 600 is Goal Zero's mid-size lantern. It combines a 600-lumen light that can shine from one side or both, a lithium battery that can also charge a phone, and three ways to recharge: USB, a Goal Zero solar panel or a built-in hand crank.

Who should buy it

• Households that want one main lantern for a kitchen or living room during outages lasting several days.
• People with a power bank, power station or solar panel: the lantern recharges from any USB source in about 6 hours.
• Anyone who prefers warm light at night. Goal Zero rates the LEDs at 3,500 K warm white.

Who should skip it

• Buyers who want hours of maximum brightness. Both sides on high lasts 2.5 hours per charge.
• Households that would rather stock disposable batteries than recharge. The lantern takes no AA or D cells; a battery lantern such as the Energizer WeatheReady runs on stored D or AA cells.
• People storing it in a cold garage or car. Goal Zero lists an operating range of 32 to 104°F.

Strengths

• Very long low mode. Up to 320 hours with one side on low, or 180 hours with both sides on low.
• Three ways to recharge. USB in about 6 hours, a Nomad 10 solar panel in as little as 6 hours of sunlight, or the hand crank.
• Crank as last resort. Goal Zero rates 1 minute of cranking for 10 minutes of low light, enough to get through a night with no other power.
• Charges a phone. The USB output delivers up to 7.5 W, and the lantern can charge and discharge at the same time.
• Directional light. Lighting one side halves the drain when you only need light on a table or a wall.

Drawbacks

• 2.5 hours at full output. Both sides on high drains the battery fast; use low or one side.
• Small battery for phone charging. 18.98 Wh is a modest store. Every phone top-up comes out of your lighting time.
• Solar panel sold separately. The Nomad 10 is a separate purchase.
• Storage maintenance. Goal Zero recommends charging it every 3 months, and lists the battery's life as hundreds of cycles.
• Not waterproof. Goal Zero lists no water rating.

How it compares

Using it in a long outage

Make one charge last a week

Goal Zero's runtime table is the planning tool. With one side on low, a full charge lasts up to 320 hours. If the family uses it 5 hours each evening, that is about 64 evenings in theory (320 ÷ 5), far more than any one outage. Both sides on high for the same 5 hours empties it in a single evening. Most households land in between: one side on high while cooking and cleaning up, then low for the rest of the evening.

1. 01Charge it fully from a wall outlet when a storm is forecast.
2. 02During the outage, recharge it in the daytime from a power bank, a power station or a Goal Zero solar panel, so the stored battery is reserved for night.
3. 03Avoid using it to charge phones unless nothing else is available. A power bank such as the Anker 737 holds far more.
4. 04Keep the crank as the reserve. Ten minutes of cranking gives about 100 minutes of low light.

Storage between outages

Goal Zero's FAQ recommends charging the lantern every 3 months, and its spec table says to charge every 3 to 6 months in storage. Set a reminder. Store it indoors: the listed operating range is 32 to 104°F, so a winter garage or a hot car trunk is the wrong place. A lantern that sits dead in a closet for a year is no better than no lantern.

Pair the lantern with a headlamp per person, such as the Black Diamond Spot 400, and one long-throw flashlight like the Fenix PD36R PRO for checking outside. Never use fuel-burning lanterns, grills or camp stoves indoors for light or heat; they produce carbon monoxide.
