The Actual Lumen Maintenance Life is not guaranteed by this laboratory it is merely a standardised method of extrapolation. The data specified in this report relates to the sample measured under standard conditions specified in the Test Specification, and may not necessarily relate to other similar luminaires or other operating conditions. The tests and measurements covered by this document are traceable to Australian national standards of measurement. This report shall only be reproduced in full unless approved in writing by Light Emission Distribution Laboratory (LEDLab).

Product

Luminaire Type: HiBay

Name of Product: 90w LED High Bay Model/Catalogue number: 61900-90

Description: Suspended IP65 Hibay Black Body Glass lens 195mm

LED Brand Name/ Model No: Osram DURIS S 5 GW PSLR31.EM

Driver Brand name/Model No: Osram Optronic OT 165/170-240/1A0 4DIMLT2 E

Results

Supply Voltage 254.0V (1.06x rated voltage) 50Hz, Current 0.345A and Power 83.6 W at 0.955 Power Factor.

In-Situ Temperature Measurement Test (ISTMT) on LED measuring point 59 Deg C

Total driver output current being supplied to panel 560 mA.

Consideration of LED arrangement, yields an LED drive current of maximum 70mA. Note that the drive current

employed in the LM80 report is 160mA.

Conclusion

The calculator below gives a projected 70% lumen maintenance life under normal operating conditions of 61,100

hours, however, according to IES TM-21-11 the luminaire manufacturer can only claim “6 times the test hours” or

54000 hours. At 54000 hours of life, the lumen maintenance is projected as 73.15%.

Test specifications

The luminaire was tested in accordance with the procedures given in IES LM-84-14, "IES Approved Method for

Measuring Luminous Flux of LED Luminaires" using the In-Situ Temperature Measurement Test (ISTMT) referred

to in IES TM-21-11 “Projecting Long Term Lumen Maintenance of LED Light Sources". In particular, the method

of Test is described in IES LM-84-14 Annex A Recommendations for Measurement of In-Situ conditions LED Case

Temperature, TS. In addition, the conditions of test are as specified in AS/NZS 60598.2.1:2014 Clause A17; this

refers to Clause 12.4 of AS/NZS 60598.1.

Use has been made of IES LM-80-2008 test report Test Documentation No.: Osram Test Document no: 160022W1,

Osram Opto Semiconductors and the Energy Star Calculator Spreadsheet based around IES TM-21-11. This method

is the preferred Option 1 in Appendix 1 – US Department of Energy –Guide to evaluating LED lumen

maintenance.pdf.

The data specified in this report apply to the luminaire with the components nominated and only if it uses the LED

package described in the above LM-80 report, and will not be applicable to the use of other LED sizes or ratings,

other drive Currents, nor to any other luminaire of similar design.

Test Configuration & Method

The luminaire was measured for LED Chip temperature at the point marked TMPLED on the DURIS S 5

GW PSLR31.EM chip by the laboratory as this is specified in the Test Documentation No.: 160022W1 – 3rd

February 2016.

• The Report gave chip dimensions Illustration 1 this laboratory concluded the yellow section of the chip

measures 3.3 mm long by 3.1 mm wide. The chips in the luminaire were inspected and measured in Length

3.3 mm long by 3.1 mm wide. This laboratory concludes the chip is the same shape and size as shown in the

Report but cannot be held responsible that the chip is the same. Responsibility for this rests with the

luminaire supplier.

• The luminaire as supplied by the client was tested in the controlled temperature room at 40 Deg C as it was

marked Ta = 40°C.

• The luminaire was hung facing down as it is constructed with suspension points.

• The LED was measured with a fine 36-gauge Type K thermocouple glued with two part clear epoxy to the

TMF point in the Report, see Illustrations 1 and 2.

• A calibrated reference thermometer together with the thermocouple of total Uncertainty 0.4 Deg C was used to

take this measurement.
