Philips 9.5W Warm Glow LED Review - if you want a dimmable LED with no buzz and no flicker, read this

Light quality: Very good. We could not tell the difference between this and an incandescent bulb.
Light quality when dimmed: Excellent. The bulb dimmed very smoothly with no flicker using both our leading and trailing edge dimmers. Not only that, its colour temperature changed slightly just as incandescent bulbs do.
Buzz/hum: None detectable.
Buzz/hum when dimmed, Lutron MACL-153M (leading edge) dimmer: Barely perceptible. It is unlikely you would hear the buzz in a quiet room.
Buzz/hum when dimmed, Leviton 6615 (trailing edge) dimmer: Completely silent.
RF interference: It was difficult to detect electromagnetic interference, even with a meter.
Price: $11.98 at Home Depot Canada.
