|Manufacturer||Ebay seller: australiandoll (other LEDs from Ebay seller: australiandoll)|
|Fitting Type||GU10 (other GU10 LEDs)|
|Light Type||Downlight (PAR)|
|Review Notes||This is the most efficient GU10 tested to date. But it also has the worst CRI value seen to date. Ships in a white box with no markings. Carries CE approval and RoHS labels. Claimed light source: 7W Epistar chip. Dimming tested using a Clipsal 32E450UDM Universal Dimmer as dimming performance was much poorer on our standard leading edge dimmer (see gallery).|

Graph notes: Dimming performance can be highly dependant on the type of dimmer, the number of lights in the circuit and other factors. Results in your house might vary. Mouse over the graph for more details. Position 10 = Not dimmed. Position 1 = Fully dimmed.
Angle: 72° (±36° 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.
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.
Percent: 66%, Index: 0.121 (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.
