Test Date 2013-05-31
Review Notes Light sent in wrong product packaging. Price includes $15.95 for recommended driver KAA-12E35IAD. Unit has large heat sink and runs cool as a result. CRI is excellent for a LED light. Designed to fit a 92mm cut-out. Also available in warm white and smaller size and wider angle. A more expensive non dimmable version with 10 year warranty is also available.
DC Driver voltage output to LED: 34V.
Measured driver current: 342 mA
Claimed light source: Edison Edi-Power HR Series.
Price $69.15 (AUD) from WattSaver Lighting Solutions on 29th of May 2013

Dimming measurements

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.

Distribution Graph

Angle: 32° (±16° 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

Representation of color spectrum

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

Graph of measured flicker

Percent: 14%, Index: 0.044 (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. [More details]
