General Energy Star Luminaire Requirements Correlated Color Temperature (CCT)
The luminaire must have one of the following designated CCTs and fall within the 7-step chromaticity quadrangles as defined in the Appendix.
Nominal CCT 2700K 3000K 3500K 4000K Color Maintenance
Target CCT (K) and tolerance 2725 ± 145 3045 ± 175 3465 ± 245 3985 ± 275
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.
Color Rendering Index (CRI) Dimming
Warranty
Target Duv and tolerance 0.000 ± 0.006 0.000 ± 0.006 0.000 ± 0.006 0.001 ± 0.006
Minimum CRI (Ra) of 80. In addition, the R9 value must be greater than 0. 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. A 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 Bases MR16 | 06.26.2012 | Page 2 MR 16 | Date: 06.26.2012 | OS SJ AE | RS CE
Must be a lamp base listed by ANSI.
General Energy Star Luminaire Requirements For lamp power ≤5 W and for low voltage lamps, no minimum power Power Factor
factor is required For lamp power >5 W, power factor must be ≥ 0.70 Note: Power factor must be measured at rated voltage.
Minimum Operating Temperature
Integral lamp shall have a minimum operating temperature of -20°C or below. ≥ 120 Hz
LED Operating Frequency
Note: This performance characteristic addresses problems with visible flicker due to low frequency operation and applies to steady-state as well as dimmed operation. Dimming operation shall meet the requirement at all light output levels.
Electromagnetic and Radio Frequency Interference
Integral LED lamps must meet the appropriate FCC requirements for consumer use (FCC 47 CFR Part 15).
Audible Noise
Integral lamp shall have a Class A sound rating.
Transient Protection
Power supply shall comply with IEEE C.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.
Operating Voltage MR16 | 06.26.2012 | Page 3 MR 16 | Date: 06.26.2012 | OS SJ AE | RS CE
Lamp shall operate at rated nominal voltage of 120, 240 or 277 VAC, or at 12 or 24 VAC or VDC.
MR 16 – Energy Star Criteria Item
ENERGY STAR Requirements
Definition
Directional lamp means a lamp having at least 80% light output within a solid angle of π sr (corresponding to a cone with angle of 120°)
Minimum luminous efficacy Lamp diameter ≤ 20/8 inch
40 lm/W
Color Spatial Uniformity
The variation of chromaticity within the beam angle shall be within 0.006 from the weighted average point on the CIE 1976 (u’,v’) diagram.
Maximum lamp diameter
Not to exceed target lamp diameter
Maximum overall length (MOL)
Not to exceed MOL for target lamp
Minimum center beam intensity - MR16 lamps
Link to online tool at http://www.drintl.com/htmlemail/Energystar/Dec09/ESIntLampCenter BeamTool.zip (Note: maximum allowable beam angle = 50°.)
Lumen Maintenance
≥ 70% lumen maintenance (L70) at 25,000 hours of operation
Rapid-Cycle Stress Test
Cycle times must be 2 minutes on, 2 minutes off. Lamp will be cycled once for every two hours of required minimum L70 life.
