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

Aiden Tsang
💧 Even though we say "waterproof," water resistance can vary greatly depending on the IPX standard. It's important to choose a waterproof flashlight with the appropriate IPX rating for your usage scenario, such as rainy weather, waterside activities, or professional use.

What is the IPX waterproof standard?

IPX (Ingress Protection) is a waterproof performance rating based on the international standard IEC 60529. The higher the number, the greater the waterproof performance and the wider the range of environments in which it can be used. When choosing a flashlight, it is important to check the IPX rating that matches your usage scenario.

IPX Rating List

IPX0
No waterproofing
IPX1
Resistant to vertical dripping water
IPX2
Resistant to dripping water at up to 15° tilt
IPX3
Resistant to spraying water at up to 60° angle
IPX4
Resistant to splashing water from any direction (daily life waterproofing)
IPX5
Resistant to water jets from any direction
IPX6
Resistant to powerful water jets (M39 equipped)
IPX7
Resistant to immersion in 1m of water for 30 minutes
IPX8
Resistant to immersion in water beyond 1m depth

Difference between Daily Life Waterproof (IPX4 equivalent) and IPX6

Recommended Models by Use Case

Scenarios where M26 is suitable

Ideal for everyday outdoor use, camping, disaster preparedness, and other uses where splashing water resistance is sufficient. With a large 5000mAh battery and Type-C charging for long-term use, it is recommended for those who prioritize cost performance.

Scenarios where M39 is suitable

Ideal for fishing, waterside work, outdoor professional work in heavy rain, and other uses requiring waterproof performance that can withstand strong water jets. It offers professional-grade specifications with IPX6 waterproofing, 3M impact resistance, and ultra-high brightness from an XHP160 chip.

Frequently Asked Questions (FAQ)

What is the difference between IPX6 and IPX7?
IPX6 indicates resistance to powerful water jets, while IPX7 indicates resistance to immersion in 1m of water for 30 minutes. If there's a chance of dropping it into water, IPX7 or higher is necessary, but IPX6 is sufficient for use in rainy weather or by the water.
Is it okay to use a daily life waterproof flashlight in the rain?
It's generally fine in light rain, but it's best to avoid using it in heavy rain or environments where it might be directly splashed. If you need reliable waterproof performance, we recommend the M39 with IPX6 or higher.
Which is more suitable for fishing, M26 or M39?
For fishing, as there's a possibility of direct splashing, we recommend the M39 with IPX6 waterproofing. The M26's daily life waterproofing might not be sufficient for heavy splashing.
Does waterproof performance deteriorate over time?
Yes, waterproof gaskets deteriorate over time. If using for a long period, we recommend checking the waterproof performance regularly and refraining from waterside use if you notice any abnormalities.
