LED Light Bulbs Key Product Criteria

Performance Characteristics:Current Criteria:
Correlated Color Temperature (CCT)Nominal CCT: 2700K, 3000K, 3500K, or 4000K
Color MaintenanceThe change of chromaticity over the minimum lumen maintenance test period (6000 hours) shall be within 0.007 on the CIE 1976 (u�,v�) diagram.
Color Quality (Color Rendering Index or CRI)CRI >= 80, R9>0
DimmingIf a product is dimmable, packaging must state this. Minimum efficacy, light output, CCT, CRI, and power factor of dimmable lamps will be confirmed with the lamp operated at full power.
WarrantyA warranty must be provided for lamps, covering material repair or replacement for a minimum of three (3) years from the date of purchase.
Allowable Lamp BasesMust be a lamp base listed by ANSI.
Power FactorFor lamp power <= 5W and for low voltage lamps, no minimum power factor is required.
For lamp power >= 5W, power factor must be = 0.70.
Minimum Operating TemperatureIntegral lamp shall have a minimum operating temperature of -20�C or below.
LED Operating Frequency>= 120 Hz
Electromagnetic and Radio Frequency InterferenceIntegral LED lamp must meet the appropriate FCC requirements for consumer use (FCC 47CFR Part 15).
Audible NoiseIntegral lamp shall have a Class A sound rating.
Transient ProtectionPower supply shall comply with IEEE C.62.41-1991, Class A operation. The line transient shall consist of seven strikes of a 100kHz ring wave, 2.5kV level, for both common mode and differential mode.
Operating VoltageLamp shall operate at rated nominal voltage of 120, 240, or 277 VAC, or at 12 or 24 VAC or VDC.
