Review Notes A unique MR16 LED for having a CRI above 90 and using GaN on GaN technology. Unfortunately the trade off is that this is one of the most inefficient LEDs tested. Tests were conducted on a Osram ET-Redback Transformer. This transformer is not claimed to be compatible with SORAA LED MR16s, see their website for a comprehensive list of compatible transformers. Performance might be better on a compatible transformer but many Australian transformers are missing from the compatibility list. This is the hottest MR16 tested by a good margin but vendor claims their GaN technology allows higher temperatures without higher failure rates. High frequency flicker is worse than most LED lights. This is generation 1, there is a improved 2nd generation available.

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: 35° (±17.5° 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

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: 83%, Index: 0.207 (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.
