Sorry Fulk, only just saw this, but see that Rob has got in there ahead of me. Look forward to seeing the results Rob!Hi Chunky,
I have some PF 200 MEGA-FLASH bulbs that have been in my possession for several years . . . I keep thinking I'll find a use for them, but haven't done yet. They look like the ones in the picture above, except that they're clear rather than blue-coated.
If you want them, you can have them; I live just south of Kendal if that's any use in arranging a pick up (I'd be a bit reluctant to post them).
