What is IPX Waterproof Rating for Flashlights? | Differences between IPX4, IPX5, and IPX7, and criteria for choosing in rain and outdoors
What is the IPX Waterproof Rating?
IPX (Ingress Protection) is an international standard (IEC 60529) that indicates the degree of protection electrical equipment has against water ingress. A higher number signifies a greater level of protection, allowing the device to withstand harsher water environments.
Labels such as "IPX5" and "IPX7" found in a flashlight's specifications indicate different levels of water resistance. Choosing a model with an unsuitable rating for your intended use risks malfunction due to rain or splashes.
IPX Level Protection Performance Chart
Suitable for light rain or splashes. Not suitable for heavy rain or direct water jets.
Suitable for heavy rain or hose water jets. Not suitable for submersion.
Suitable for typhoons or heavy sea spray. Not suitable for submersion.
Suitable for submersion and accidental drops in water. Safe for use in rivers and oceans.
Highest level, designed for continuous underwater use like diving.
Recommended IPX Levels by Use
| Usage Scenario | Recommended IPX Level | Reason |
|---|---|---|
| Daily use / Indoors | IPX4 or higher | Minimum for accidental splashes |
| Summer festivals / Fireworks | IPX5 or higher | To cope with sudden evening showers |
| Camping / Hiking | IPX5 to 6 | Anticipating use in rain or by rivers |
| Disaster prevention / Emergencies | IPX5 or higher | Outdoor use during typhoons or floods |
| Fishing / Marine sports | IPX7 or higher | High risk of submersion or sea spray |
| Underwater / Diving | IPX8 | Requires continuous underwater use |
Comparison of IPX Ratings for Aestiquo Models
| Model | IPX Rating | Suitable Scenes | Max Brightness |
|---|---|---|---|
| M19 | IPX5 | Daily use, disaster prevention, camping, summer festivals | 〜3,000lm |
| M26 | IPX5 | Daily use, disaster prevention, camping, summer festivals | 〜3,000lm |
| M35 | IPX5 | Professional use, hiking, rescue operations | 〜8,000lm |
| M39 | IPX6 | Typhoons, heavy rain, harsh outdoor conditions | Over 16,000lm |
For most general outdoor scenarios, such as daily use, disaster prevention, camping, and summer festivals, IPX5 is sufficient. Aestiquo M19, M26, and M35 are all IPX5 compliant, making them reliable for a wide range of uses. If you frequently fish or spend time near water, choose the M39 with IPX6 or higher.

❌ "Waterproof" alone is insufficient
If a product is labeled "waterproof" but does not specify an IPX rating, its level of protection is unknown. Always check the IPX number.
❌ IPX7 does not mean continuous underwater use
IPX7 protects against "submersion at 1m for 30 minutes" and does not guarantee continuous underwater use. For extended underwater use, IPX8 is required.
❌ Waterproof ≠ Dustproof
IPX indicates only water resistance. For resistance to sand and dust, you need to check for a separate dustproof rating like "IP6X." When using outdoors, also check the dust resistance.
