The future of indoor growing lies in LED lighting, and many cultivators are recognizing the need for energy-efficient solutions by making the switch from HPS to LED technology. If you’re among those transitioning, you might be wondering how to fully leverage the advantages of LED lighting and ensure the success of your grow. To help you, we’ve compiled five crucial tips how to smoothly transition from HPS to LED lighting to follow during the transition process.


The L90 rating, as applied to LEDs, denotes the approximate duration (typically in hours) within which an LED light source is expected to diminish to 90% of its original lumen output. Essentially, it represents the time it takes for the LED to experience a 10% decrease in brightness, reaching 90% of its initial light emission.

For instance, if an LED holds an L90 rating of 50,000 hours, it signifies that after roughly 50,000 hours of continuous operation, the LED’s brightness will have declined to 90% of its original level. It’s important to understand that the L90 rating serves as a means to assess the LED’s lumen preservation over time, aiding in the estimation of its functional life and performance sustainability within various lighting applications.

LED manufacturers and lighting industry standards commonly specify L90 ratings in technical data sheets, enabling lighting designers and users to make well-informed choices when selecting LED products for specific applications. Moreover, L90 values are frequently utilized in lighting design computations to gauge the expected light output of an LED source over time and its anticipated lifespan before encountering a particular degree of lumen reduction.


Let’s clarify the difference between an LM80 report and an L90 report:

LM80 Report

LM80 (Lumen Maintenance Test for LED Light Sources) is a standardized testprocedure developed by the Illuminating Engineering Society (IES) that focuses on evaluating the lumen maintenance of individual LED-light sources (LED chips). The LM80 report provides data on the lumen output of the LED-chips over time, typically up to 6,000 hours of operation. This data allows manufacturers and users to understand how the light output of the LED-chips degrades as they age. It does not provide information about the lifespan of the entire LED fixture.

L90 Report

An L90 report, on the other hand, provides information about the lifespan of an entire LED lighting fixture. It is not a standardized test like LM80 but rather a way to indicate the operational life of the LED fixture. The “L90” value represents the time it takes for the LED fixture’s light output to degrade to 90% of its initial output. In other words, it estimates the point in time when the LED fixture will have retained 90% of its initial brightness, and it has typically reached the end of its useful life.

In summary, the main difference between an LM80 report and an L90 report is that LM80 is focused on testing and reporting the lumen maintenance of individual LED-light sources (LED chips) over time, while L90 is a measure used to estimate the operational life of an entire LED lighting fixture, indicating when it reaches 90% of its initial brightness. Both are essential in understanding the performance and reliability of LED lighting systems, with LM80 providing insights into LED-chip degradation, and L90 offering an estimation of the fixture’s useful life.


A TM-21 test report offers several benefits to LED manufacturers, lighting designers, and end-users as it provides valuable information about the expected lumen maintenance of LED light sources over time.

Some of the main benefits of a TM-21 test report are as follows:

  • Lumen Maintenance Projection: The TM-21 test report projects the lumen maintenance of LED light sources over an extended period. It allows users to estimate how much light the LEDs will produce after a certain number of hours of operation, typically up to 6 times their tested lifetime. This information is crucial for making informed decisions in lighting design and specifying LED products for various applications.
  • Useful Life Estimation: By knowing the expected lumen depreciation rate, users can estimate the useful life of an LED source. The TM-21 test report helps to understand how long the LED will maintain a certain level of brightness before it reaches a specified percentage of its initial lumen output (commonly L70, L80, or L90).
  • Product Comparison: TM-21 test reports provide a standardized way to compare the lumen maintenance characteristics of different LED products. This enables users to evaluate and select LED sources based on their long-term performance, helping to choose reliable and durable lighting solutions.
  • Warranty Determination: For LED manufacturers, TM-21 test reports can be used to determine appropriate warranty periods for their products. Knowing how the lumen output will change over time helps set realistic warranty durations that align with the product’s expected performance.
  • Energy and Cost Savings: Understanding the lumen maintenance of LED sources allows end-users to calculate long-term energy savings and estimate the total cost of ownership. Efficient and long-lasting LEDs result in reduced energy consumption and maintenance costs over the product’s lifespan.
  • Regulatory Compliance: In some regions, TM-21 test reports may be required to meet certain regulatory standards or certifications related to energy efficiency and product performance.
  • Marketing and Confidence: Providing TM-21 test reports to customers demonstrates transparency and confidence in the LED product’s performance. It reassures buyers that the manufacturer has tested and projected the product’s lumen maintenance in a standardized manner.

Overall, TM-21 test reports are valuable tools that contribute to better-informed decision-making, increased confidence in LED products, and the promotion of more efficient and reliable lighting solutions in the market.
