Color Maintenance |
The change of chromaticity over the minimum lumen maintenance test
period (6000 hours) shall be within 0.007 on the CIE 1976 (u’,v’)
diagram. |
| |
|
Dimming
NOTE: DOE is working with NEMA to develop a dimming standard for LED
lamps and luminaires. |
Lamps may be dimmable or nondimmable. Product packaging must clearly
indicate whether the lamp is dimmable or not dimmable. Manufacturers
qualifying dimmable
products must maintain a Web page providing dimmer compatibility
information.
Minimum efficacy, light output, CCT, CRI, and power factor of
dimmable lamps will be confirmed with the lamp operated at full
power. |
|
Power Factor |
For lamp power ≤5W and for low voltage lamps, no minimum power
factor is required
For lamp power >5W, power factor must be ≥ 0.70
Note: Power factor must be measured at rated voltage. |
|
Electromagnetic Interference |
FCC 47 CFR including Part 2 (Equipment Authorization) and Part
18(Technical Standardsand Emission Limits) for consumer RF Lighting
Equipment limits |
|
LED Operating Frequency |
≥120Hz |
|
Transient Protection |
Power supply shall comply with IEEEC.62.41-1991, Class A operation.
The line transient shall consist of seven strikes of a 100 kHz ring
wave, 2.5 kV level, for both common mode and differential mode. |
|
Audible Noise |
Integral lamp shall have a Class A sound rating. |
|
Minimum Operating Temperature |
Integral lamp shall have a minimum operating temperature of -20°C or
below. |
|
Warranty |
A warranty must be provided for lamps, covering material repair or
replacement for a minimum of three (3) years from the date of
purchase. |
| |
|
|
Product Packaging Language |
In English,
or English with additional languages. For products that will be
sold in Canada, packaging
must include both English and French. |
|
Dimmable lamps |
Lamp package and product information sheet must include a caution
label indicating the lamp may not be compatible with all dimmers and
identifying the Web address (URL) to find up-to-date dimmer
compatibility information. |
