Lightbulb Moment

B&Q this evening - yes, Saturday nights are full of surprises :-(

We were 'just' collecting a lamp we'd ordered. Of course it didn't come with a bulb, but it did say on the box the type that was needed. 

Half an hour at least was spent browsing the lightbulb aisle. Remember when the choice was 60 or 100, clear or pearl ?

I left TM to it and looked for a picture, having not go round to taking any earlier. 

I wonder if this actually sheds any light ....
