Light bulb moment

A very dreich day weather wise. Need to finish my marking this weekend so I suppose it's good day for this. Went for a quick coffee with thechimp, thebear and mazgilchimp1990. After leaving them, I came across an unusual busker, playing his digereedoo. What a missed opportunity. Very annoyed with myself! Instead for today's blip, I've taken a photo of a new light we have just bought which has a retro bulb.
