SKU EE-04-051
Series Home-Line
Manufacturer EcoEnergy (other LEDs from EcoEnergy)
Fitting Type MR16 (other MR16 LEDs)
Light Type Downlight (PAR)
Height 45mm
Diameter PAR16 (50mm)
Weight 45g
Warranty 1 Years
Test Date 2014-05-15
Review Notes Accepts 12V AC/DC. Claimed 35W incandescent replacement. Carries CE approval label. Was found on sale in Estonia, but vendor appears to be a Polish company. Didn't meet its specifications when tested with a common electronic transformer. Output is about the same as a 20W Halogen. Light isn't dimmable and power factor is rather poor. There is also a GU10 version of the globe. We estimated a life of 15,000 hours as the vendor doesn't state expected lifetime.

Distribution Graph

Angle: 105° (±52.5° 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: 1%, Index: 0.003 (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.
