Deco 13 Tilt White Review

General Information

ID #255
Series Deco
Manufacturer Domus Lighting (other LEDs from Domus Lighting)
Fitting Type Kit (other Kit LEDs)
Light Type Downlight (PAR)
Height 45mm
Diameter PAR35 (110mm)
Weight 263g
Warranty 3 Years
Test Date 2014-03-12
Review Notes Includes 13W Evergreen LED power supply, EV-13W-D-330mA. Driver carries RCM and CE approval labels. Advertised as dimmable with most Australian dimmers, including C-Bus. Leading edge and universal dimmer were both tested with no visible flicker, however dimming range was rather limited (does not dim very low) and there was significant dead travel using the Clipsal 32E450UDM universal dimmer (see gallery for dimming profile). Dimming performance using a HPM CAT250L leading edge dimmer was slightly better (results shown below). Suitable for 95mm cutout. 50,000 hr lifetime based on claimed lifetime for other models from the same series.
Price $51.70 (AUD) from on 13th of March 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: 97° (±48.5° 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: 4%, Index: 0.006 (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.
