When choosing a lamp, it is common to come across two technical concepts that may raise questions: operating hours and number of cycles.

Although they may seem similar, they refer to different aspects of durability and lighting performance.

In this article, ASLO explains these concepts clearly and simply, so you can make better choices.

What are operating hours?

Operating hours refer to the total time a lamp can remain switched on until it reaches the end of its useful life.

For LED solutions, these values often range between 10,000 and 50,000 hours. The higher the number, the greater the expected durability, which is especially relevant in places where lights stay on for long periods, such as industrial environments, corridors, or outdoor areas.

What is this indicator for?

• To predict when lighting will need to be replaced.
• To estimate maintenance costs over time.
• To choose solutions suitable for prolonged use environments.

 

What is the number of cycles?

The number of cycles indicates how many times a lamp can be switched on and off before it starts losing performance, showing its ability to withstand frequent and intermittent use.

Each cycle corresponds to a complete on/off event, so in spaces where lighting is activated many times a day, such as garages, bathrooms, or corridors with sensors, this indicator becomes especially important.

What is this indicator for?

• To assess resistance to repetitive use.
• To determine if the lamp is suitable for automatic systems or sensors.
• To ensure performance remains stable under very frequent use.

 

How do these two concepts differ?

Operating hours → Total time the lamp stays on.

Number of cycles → Number of times it can be switched on and off.

Both indicators are essential to evaluate a lamp’s true durability.

By interpreting them together, you can choose the ASLO solution that best suits your environment.
