The initial colour rendering index (CRI) of a LED module is measured.
Compliance:

For all tested LED modules in a sample the measured CRI shall not be lower than 3 points

from the rated CRI (see Table 1).
10 LED module life
10.2 Lumen maintenance
Replace Subclause 10.2 including its title, with the following new subclause:
10.2 Luminous flux maintenance

The rated luminous flux maintenance factor may vary depending on the application of the LED

module. Dedicated information on the chosen percentage should be provided by the
manufacturer.

NOTE 1 As the typical life of a LED module is (very) long, it is within the scope of this standard regarded

impractical and time consuming to measure the actual luminous flux reduction over life (e.g. L ). For that reason

this standard relies on test results to determine the expected lumen maintenance code of any LED module.

NOTE 2 The actual luminous flux maintenance of LED modules can differ considerably per type and per

manufacturer. It is not possible to express the luminous flux maintenance of all LEDs in simple mathematical

relations. A fast initial decrease in luminous flux does not automatically imply that a particular LED will not make its

rated life.

NOTE 3 Other methods providing more advanced insight in luminous flux depreciation over LED module life are

under consideration.

This standard has opted for “lumen maintenance codes” (see Figure 2) that cover the initial

decrease in luminous flux until an operational time as stated in 6.1. There are three codes

which define luminous flux maintenance in percent of the initial luminous flux (see Table 6).

Table 6 – Lumen maintenance code at an operational time as stated in 6.1
Luminous flux maintenance Code
≥ 90 9
≥ 80 8
≥ 70 7

The initial luminous flux shall be measured. The measurement is repeated at an operational

time as stated in 6.1. The initial luminous flux value is normalized to 100 %; it is used as the

first data point for determining LED module life. The measured luminous flux value at an

operational time as stated in 6.1 shall be expressed as maintained value (= percentage of the

initial value).

It is recommended to measure the luminous flux at 1 000 h intervals (expressed as a

percentage of the initial value) for a total equal to an operational time as stated in 6.1.

NOTE 4 This will give an additional insight as to the reliability of the measured values, but assigning a code does

not imply a prediction of achievable life time. LED modules with a higher code could be better or worse than LED

modules with a lower code.

For marking of the luminous flux maintenance factor x and the lumen maintenance codes, see

Table 1.

Compliance at 25 % of rated median useful life L with a maximum of 6 000 h test duration:

For compliance of family members, refer to 6.2.3.

An individual LED module is considered as having passed the test when the following criteria

have been met.

1) The measured luminous flux value at 25 % of the rated median useful life (with a maximum

duration of 6 000 h) shall not be less than the initial luminous flux, multiplied by the rated

luminous flux maintenance factor x.

2) The calculated luminous flux maintenance (being the ratio of the measured maintained

and initial luminous flux) shall correspond with the “lumen maintenance code” as declared

by the manufacturer or responsible vendor.

Given a sample of n LED modules according to Table 7 being subjected to the 25 % of rated

median useful life test with a maximum of 6 000 h, it is deemed as having passed the test, if

at the end of the test, at least 90 % of the LED modules have passed.

Method of measuring LED module characteristics
A.1 General

Unless otherwise specified in Clause A.1, for general conditions of photometric and

colorimetric measurements CIE S 025/E:2015, Clauses 4 and 5 apply.

Unless otherwise declared, LED modules do not require any ageing prior to testing. An ageing

period of up to 1 000 h may be specified by the manufacturer.

Unless otherwise specified, all measurements shall be made in a draught free room at a

relative humidity of 65 % maximum.

The temperature at the t -point shall be set at the recommended maximum LED module

operating temperature value, t for the measurements. If not accessible, the
p rated

manufacturer shall indicate a temperature monitoring point. If heat sinks are needed for the

correct operating of the LED module and the LED module does not have a heat sink, a

suitable temperature controlled heat sink may be used.

Interpolation techniques for photometric and colorimetric data at t may also be applied (see

also CIE S 025/E:2015, Annex C for information). Measurements may be performed at

different temperatures. For this, the relation between the two temperatures (t and a
