Mono Lens 10W LED Downlight White Review

General Information

ID #246
Manufacturer Domus Lighting (other LEDs from Domus Lighting)
Fitting Type Kit (other Kit LEDs)
Light Type Downlight (PAR)
Height 90mm
Diameter PAR35 (110mm)
Weight 334g
Warranty 3 Years
Test Date 2014-02-05
Review Notes ±15° adjustable gimbal frame. Suitable for 70 mm cutout, includes adaptor ring to suit 90 mm hole. Includes 10W Evergreen LED power supply, EV-10W-D-230mA. Driver carries C-Tick and CE approval labels. Claimed light source: Sharp COB LED chip. Advertised as dimmable with most Australian dimmers. Leading edge and universal dimmer circuit were both tested with no visible flicker, however dimming range was rather limited (does not dim very low) on a 32E450UDM universal dimmer. Dimming performance was measured using a HPM CAT250L leading edge dimmer (see results below).
Price $52.80 (AUD) from on 4th of February 2014

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: 57° (±28.5° 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: 2%, Index: 0.005 (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.
