| Review Notes | Carries CE approval markings. Company doesn't list any part number or model number for this globe. Company claims efficacy of 65lm/w. But also claims 3W and 250lm (which would be 83lm/w). They further claim you "will save you over 400% in energy operating costs". Neither of these claims make mathematical sense. Otherwise it is a pretty reasonable small LED globe, assuming you don't need dimming. |

Distribution Graph
Angle: 140° (±70° 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: 2%, Index: 0.003 (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.
