6.5W GU5.3 LED Lamp Review

General Information

ID #202
SKU 871829121781700
Series myAmbiance
Manufacturer Philips (other LEDs from Philips)
Fitting Type MR16 (other MR16 LEDs)
Light Type Downlight (PAR)
Height 48mm
Diameter PAR16 (50mm)
Weight 48g
Warranty 1 Years
Test Date 2013-09-23
Review Notes Claims similarity to 35W halogen MR16. Carries CE and C-Tick label. Was unable to find any applicable warranty details for Australian sales. Would have scored higher except for lack of dimming and warranty info. Overall a reasonable MR16 offering. If dimming is required there are two more expensive 7W versions of this light. Version #1, Version #2. In some markets this light is called the "CorePro LEDspotLV", product code 929000211302
Price $24.98 (AUD) from Bunnings Warehouse on 20th of September 2013

Distribution Graph

Angle: 32° (±16° 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: 1%, Index: 0.002 (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.
