How to Choose a Waterproof Flashlight: IPX Rating Differences and a Comparison of Aestiquo M39 and M26

Aiden Tsang
💧 The waterproof performance varies greatly depending on the IPX rating. It is important to choose a flashlight with a waterproof rating suitable for your intended use, such as in rainy weather, near water, or for professional applications.

What is the IPX waterproof standard?

IPX (Ingress Protection) is a classification of waterproof performance based on the international standard IEC 60529. A higher number indicates better waterproof performance and a wider range of environments in which the product can be used. When choosing a flashlight, it is important to check the IPX rating that matches your intended use.

Frequently Asked Questions (FAQ)

What is the difference between IPX6 and IPX7?
IPX6 indicates resistance to strong water jets, while IPX7 indicates resistance to immersion in water up to 1m for 30 minutes. If there's a possibility of dropping it in water, IPX7 or higher is required, but IPX6 is sufficient for use in rainy weather or near water.
Can I use a daily life waterproof flashlight in the rain?
It is fine for light rain, but we recommend avoiding use in heavy rain or environments where splashes directly hit the flashlight. If reliable waterproof performance is needed, please choose the M39 with IPX6 or higher.
Which is more suitable for fishing, M26 or M39?
For fishing, as there is a possibility of direct splashes, we recommend the M39 which is IPX6 waterproof. The M26's daily life waterproof may not be sufficient for heavy splashes.
Does waterproof performance deteriorate over time?
Yes, waterproof gaskets deteriorate over time. For long-term use, we recommend regularly checking the waterproof performance and refraining from using it near water if you notice any abnormalities.
