Philips Hue E27 A60 Colour Bluetooth Bulb was $99, now $79 - a $20 saving!
This is the Edison screw fitting, but if you need a bayonet globe, see Philips Hue B22 A60 Colour Bluetooth Bulb.
There seems to be a few deals going across their Hue lighting range.
I actually don't get how people justify a $79 light bulb, i personally use the smart globes from kogan ~$10 on sale. I haven't had issues and it's been 2 years, but if the light bulb fails for whatever reason, you need to replace it for another $79 bulb? what are the pros of getting a branded bulb?
