|Manufacturer||Lighting Matters (other LEDs from Lighting Matters)|
|Fitting Type||Kit (other Kit LEDs)|
|Light Type||Downlight (PAR)|
|Review Notes||Kit includes a ECOPACT constant current LED driver Model: PE-294B1230. Driver carries C-Tick and CE approval markings. Manufacturers advise this downlight is 'dimmable using any standard trailing edge (or leading edge in some cases) dimmers'. They Recommend using a Luxman T400P for best dimming performance. Dimming was tested using a Clipsal 32E450UDM universal dimmer. Makes use of both a diffuser and a reflector for lower glare. Has a significantly higher CRI value than the average LED. Runs cool with no significant flicker.|

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.
Angle: 81° (±40.5° 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.
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.
Percent: 7%, Index: 0.021 (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.
