Bought 3 18W (100W equivalent) bulbs from Wickes today.
£1.99 each normally, on offer 3 for 99p along with other lower wattage 'standard' Philips energy saving bulbs. Screw or standard bayonet fitting.
SKU code for 18W bayonet, 190904. Image for illustration only ('60W' version)
INSTORE ONLY. No expiry date shown instore.
Can normally get 60W equivalent cheap (10 for £1), but not the 100W.
I've found Philips to be the best bulbs.
