- LED performance is subject to inherent variability due to manufacturing processes, so LED manufacturers sort LEDs into performance bins to improve consistency. However, binning does not correct for variability. - LED output degrades over time through lumen depreciation. The rate of degradation depends on factors like operating temperature and conditions. Proper ventilation and operating within specified ranges can provide long service life. - The document provides specifications for Traxon Cove Light AC HO and HO Graze LED lighting fixtures, including lumen output, beam angle, efficacy, dimming compatibility, and more. Photometric data is given for different models and color temperatures.

LED CHARACTERISTICS Because LEDs are semiconductor devices, their performances are subject to inherent variability commonly found in semiconductor industry. To improve consistency in performance across the
same product, LED manufacturers “sort” LEDs into bins according to different preset parameters, such as forward driving voltage, illumination, etc. Whereas binning is a sorting function, it is not a correction process.
Inherent variability in the manufacturing process results always in different binning distributions according to different production lots. Traxon uses automatically binned LEDs on its products, thereby minimizing output
variations within the model range.
As with all electronic devices, LED output degrades over time – a term called lumen depreciation. This also explains why it is nearly impossible to expect photometric performances of two LED products with different
service life spans to be the same. The rate of LED degrade is a complicate function of many factors such as operating efficiency, duration of continuous operation, and more significantly, environmental conditions (ambient
temperature for example). If allowed working under optimal operating temperature range and with good ventilation, LED devices enjoy long service lives over conventional light sources. When using/installing LED devices,
care should be taken to ensure that the devices will operate within the operating conditions specified in respective product literature.
Lumen measurement compiles with LM-79-08 standard.
Lumen maintenance is calculated based on LM-80 compliant measurement.

Cove Light AC HO / HO Graze
The Cove Light AC HO offers a range of cold, neutral, or warm white
with a 120x120 degree beam angle for general lighting, wall washing,
and alcove illumination, while the Cove Light AC HO Graze offers higher
brightness and further options in optics. Controlled by leading/trailing
edge phase-cut dimmers, the Cove Light AC HO/HO Graze offers 100%
to 5% dimming resolution without flickering, and boasts 60 - 69 lm/W.
