Many consumers are asking why the temperature rising test for 12V pool light is so important,

1. Compliance requirements

International standards (e.g., IEC 60598-2-18, UL 676) clearly require that underwater replacement of swimming pool lights must pass a temperature rise test to ensure compliance with safety certifications (e.g., CE, UL).

Some national regulations require that swimming pool equipment in public places must pass temperature rise tests before it can be put into use.

2. S

1)Aging of materials (such as sealant failure, plastic deformation), resulting in water leakage or short circuit.

2)Risk of electric shock (high temperature may accelerate insulation deterioration).

3)Risk of scalding (for example, the surface temperature of the lamp is too high, which may cause injury to the human body).

The temperature rise test ensures that the temperature does not exceed the safety limit when the underwater pool lights led is working at the rated power.

3. Performance and life

High temperature will reduce the life of the LED light source (such as accelerated light decay) or damage the electronic driver components.

The temperature rise test can verify that the heat dissipation design is reasonable and avoid premature failure of lamps due to overheating.

So you see, temperature rise testing can not only meet market access, but also identify design defects in advance and improve product reliability.

Heguang Lighting is a professional manufacturer of IP68 underwater lights.

1. Test standards

Usually refer to IEC 60598-1 (general requirements) and IEC 60598-2-18 (special requirements for pool lights), or UL 676 (North American standard).

2. Test conditions

Lamps work in the harshest conditions (such as rated maximum power, confined environments, or simulated pool water temperatures).

The test time is generally in a heat-stable state (usually lasting 4-8 hours until the temperature change is < 1℃/ hour).

3. Measuring points

Key parts: LED board, LED driver, shell surface, cable interface, etc.

Tools: Thermocouple or infrared thermograph to record temperature data.

4. Criteria

The temperature rise of each component shall not exceed the standard limit (e.g.

Insulation material: <=90℃ (IEC standard)

Contact surface: <=60 ℃ (requirements for scald prevention)

5. Environmental simulation

Part of the test will be carried out in the water temperature control box to simulate the actual environment of the pool (such as the water temperature of 25℃~30℃).

The best underwater pool lights that passes the temperature rise test can not only ensure the safety of users, but also extend the service life and reduce maintenance costs, which is an indispensable part in product development. Contact us now if you have any pool light bulb enquiry!
