COB LED MR16 7W Spotlight Review

General Information

ID #217
Series N/A
Manufacturer Ebay seller: australiandoll (other LEDs from Ebay seller: australiandoll)
Fitting Type MR16 (other MR16 LEDs)
Light Type Downlight (PAR)
Height 75mm
Diameter PAR16 (50mm)
Weight 63g
Warranty 2 Years
Test Date 2013-10-24
Review Notes This is the most efficient MR16 tested to date. But it also has one of the worst CRI values seen to date. As with many EBay lights performance claims have been exaggerated. Ships in a white box with no markings. Carries CE approval and RoHS labels. No RCM or C-Tick approval. Claimed light source: Epistar Chip. Manufacturer claims this globe is dimmable. Severe flicker and no dimming when connected to a leading edge dimmer. Severe flicker on most dimming levels and limited dimming performance was measured using a universal dimmer. Use on either leading edge or universal dimmers will likely damage the electronics and consequently shorten the life of this globe.

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: 70° (±35° 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: 4%, Index: 0.009 (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.
