1W mini Globe Review

General Information

ID #176
Series N/A
Manufacturer iGlobe (other LEDs from iGlobe)
Fitting Type B22 (other B22 LEDs)
Light Type Globe
Height 68mm
Width 45mm
Weight 46g
Warranty 5 Years
Test Date 2013-07-30
Review Notes Claimed replacement for 25W incandescent, but in our opinion it is closer to a 10W incandescent. Regardless of this, it is still reasonably efficient and very low wattage. Power factor is very poor, but at 1w it doesn't matter too much. CRI is poor. Some sensitive people may perceive some 100Hz flickering. Even light distribution. Would make a good night light. Carries C-Tick N30601, no RCM or Australian recognized electrical safety approval marking.

Distribution Graph

Angle: 151° (±75.5° 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: 89%, Index: 0.244 (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.
