Deal starts at 2.59pm today (05 Feb). 47% off. Current price is £49.87 so I make that a discounted price of £26.43.
It's the B22 Bayonet bulb which doesn't seem to get discounted as frequently as the Edison bulbs. Amazon mobile app says it's Prime customers only, but desktop says Early Access which might mean it will be opened to non Prime customers after a period of time. It doesn't say whether only 1 or multiple permitted, often it's just 1.
Best way to find it is to go to 'Today's Deals' then filter on 'Department: Lighting' and then scroll down.
This is my first post so go easy on me! Been using hotukdeals app for a few months now and it's been very useful to me, so this is me paying back to the community.
