Well it's the middle of summer, the longest day, so I thought I would make an inappropriate post.
I've been sorting through my fathers stuff in the loft, and opened some boxes of photography gear. There's some lightbulbs in boxes. A couple of red ones for darkroom use, and a couple of very ordinary looking clear pearl ones.
A look at the box tells me they are Philips Photoflood, with an ridiculous rating of 275 Watts. Though dad's are ancient 1970's ones, they are still available today:

I suspect they would probably melt most lamp fittings, and wouldn't have a long life, either, but it's good to see that such excessive products still exist in these days of CFL's.
And yes, I tried one briefly, mackerel was it bright, glad I didn't look directly at it, black spots on your retina aren't good for lookahead.
But come winter and dark evenings, I just might have a play with one.
Footnote: My 200 Watt one I bought last autumn made it through winter, doing a grand job, but it expired in March, so I'm planning ahead, I can't cube in dingy light.
