B&Q Philips Hue Color Bulbs £40 with Code: CLUBD86S and free delivery. Cheapest these have been in 2017!
B&Q have been doing a discount on £50+ items but didn't stock any Color hue bulbs so it was only good for multiple hue dimmer switches, until today! They now do Hue Color Bulbs V3 for £50- but if using the code CLUBD86S4 at checkout the price is brought down to £40! (only seems to work for one bulb per order at this price) and still qualifies for free delivery (for orders over £50)
Cheapest Price i have seen since before Christmas, £50 everywhere else. Voucher Code valid until end of January so be quick
Note: you need the Hue Hub for it to connect to so will not be any use on its own unless used as an expensive plain LED bulb. This is the richer color bulb (V3)
EDIT: They now stock the B22 version as well which will also qualify for same offer:http://www.diy.com/departments/philips-hue-led-colour-ambience-smart-light-bulb-bayonet-cap-b22/1525075_BQ.prd
