4 points for choosing a flashlight for summer nighttime outings

① Compact & Lightweight: Fits in a yukata or pocket

When attending fireworks displays and summer festivals, you want to keep your belongings to a minimum. A compact model that is palm-sized and weighs around 100g can be carried in the sleeve of a yukata, a pouch, or a pocket. Models with clips can be attached to bags.

② Waterproof Performance: Handles sudden summer rain and sweat

Summer brings a high risk of getting wet from sudden torrential downpours, sweat, and playing in rivers. Choosing a waterproof model with IPX5 or higher will provide peace of mind. For details on waterproof standards, please refer to the IPX Waterproof Rating Guide.

③ Appropriate Brightness: 200-500lm is sufficient for night roads

For walking home from fireworks displays or taking a night stroll, 200-500lm is sufficient. Too much brightness can be bothersome to people around you. Models with multiple brightness modes allow you to adjust according to the situation. For guidance on choosing lumens, please refer to the Lumens Selection Guide.

④ Long-lasting illumination: Peace of mind even on long journeys home

Returning from fireworks displays and summer festivals can be time-consuming due to crowds. Choosing a model that can illuminate for 5 hours or more in medium brightness mode will provide peace of mind. USB rechargeable models can also be recharged with a mobile battery.

Frequently Asked Questions

Is it strange to bring a flashlight to a fireworks display?
Not at all strange. The path home from fireworks displays often involves crowds, dark alleys, and steps, so a flashlight is an effective safety measure. A compact model can be carried discreetly in a pouch. It's especially essential if you're with children or the elderly.
Can it be carried with a yukata?
Compact models like the M19 can be carried in the sleeve of a yukata, a drawstring bag, or a pouch. Models with clips can be attached to the outside of your bag. Heavy models are not suitable for yukata, so we recommend choosing a lightweight and compact model.
How can I use it without bothering others?
In crowded areas, use low to medium brightness mode and shine the light towards your feet so it doesn't directly hit other people's faces or eyes. It's good manners to use high brightness mode only in dark places with fewer people.
