| Series | Hue |
| Manufacturer | Philips (other LEDs from Philips) |
| Fitting Type | GU10 (other GU10 LEDs) |
| Light Type | Downlight (PAR) |
| Height | 72mm |
| Diameter | PAR16 (50mm) |
| Weight | 99g |
| Warranty | 2 Years |
| Test Date | 2014-05-28 |
| Review Notes | Light measured based on default start-up settings. No wireless bridge was available at time of testing so dimming performance was not tested. Claims dimming from 5%-100% brightness using Philips' Zigbee Light link based wireless bridge. Not compatible with other dimmers. Claimed maximum lumen output of 250lm@4000K, 6.5W. 6.5W maximum operation power, 0.45W maximum standby power. Claims 16 million colors. Claims CRI>80 from 2000-4000K. Flicker frequency ~= 1kHz so flicker is so fast as to be imperceptible. Carries CE approval label. Wireless bridges can be purchased as part of 3 bulb starter kits for an eye watering $300USD. |

Distribution Graph
Angle: 39° (±19.5° from bottom), Maximum lux:
Graph notes: Shows the intensity of the light when viewed from different angles. Normal omni-directional globes have a fairly constant output all the way around (excepting directly above). Downlights have a narrow range at the bottom in which the light is emmited, this determines their angle.
Spectrum Graph
Graph notes: Shows the breakdown of the LED light into its component colors. With short wavelength ultraviolet on the left and long wavelength infrared on the right. The green line represents the relative absolute strength of the light at each frequency, while the red line represents what the typical human eye would see. The human eye is most sensitive to green light, but much less sensitive to purples and deep reds.
Flicker Graph
Percent: 84%, Index: 0.356 (lower is better in both cases)
Graph notes: Shows variation in light output over 1/10th of a second, with relative light output on the Y axis and time on the X Axis. Measured with a photodiode connected to an Oscilloscope. Ideally the yellow line should be flat. Low frequency high amplitude waveforms mean there is a possibility of noticeable flicker, but sensitivity to flicker varies between people.
