TEK10 Warm White Downlight Kit Review

General Information

ID #318
SKU EV-TEK10-W-WW
Series EVERGREEN TEK-10
Manufacturer Domus Lighting (other LEDs from Domus Lighting)
Fitting Type Kit (other Kit LEDs)
Light Type Downlight (PAR)
Height 38mm
Diameter PAR33 (104mm)
Weight 183g
Warranty 3 Years
Test Date 2014-09-19
Review Notes A fairly low profile LED, that despite the smallish heatsink doesn't run too hot. Good for ceilings with limited roof clearance. Includes EV-10W-D-250mA 13W dimmable LED power supply. Driver carries RCM and CE approval labels. Dimming free of visible flicker was tested on both a HPM CAT250L leading edge dimmer (see gallery) and a Clipsal 32E450UDM universal dimmer (see results below). Guaranteed by the manufacturer as dimmable on a Domus EV-DIMMER, the light "may work on others but not tested". Very good power factor and reasonably priced.

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: 98° (±49° 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: 16%, Index: 0.048 (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.
