Review Notes Third generation of consumer LED bulb from Philips. It replaces their similar looking 12.5W globe and their 13W globe. At the time of the review this is the brightest bayonet style globe available on the market. Efficiency is also excellent, especially considering the frosted cover. CRI is average & flicker level is acceptable. Runs just a little hot, is slightly oversized and isn't dimmable however. If you want a really bright LED, this is the globe you want.
Price $19 (AUD) from Bunnings Warehouse on 6th of May 2015

Distribution Graph

Angle: 167° (±83.5° 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: 26%, Index: 0.074 (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.
