6W GU10 WW LED Lamp Review

General Information

ID #134
SKU ZD-0626
Series N/A
Manufacturer Ecolume (other LEDs from Ecolume)
Fitting Type GU10 (other GU10 LEDs)
Light Type Downlight (PAR)
Height 57mm
Diameter PAR16 (50mm)
Weight 60g
Warranty 1 Years
Test Date 2013-05-28
Review Notes Jaycar claim a lifetime of 30,000+ hours but also state their warranty period is just 3 months. Dimming performance was rather poor. Light output was excellent, for a small GU10, despite being just below their 530lm claim. Claims to use a Shineon 6W LED chip. Also available in cool white.
Price $29.95 (AUD) from Jaycar Electronics on 26th of May 2013

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: 51° (±25.5° 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: 3%, Index: 0.007 (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.
