I bought a large china ball from Ikea the other day and fitted it with a 500w EHD bulb from osram. I then proceeded to put 250 inside the ball as a heat barrier so that the paper lantern would not burn. The light from it looks good but I'm still a little nervous to use it for more than a couple of minutes at a time. What are some ways that you guys have made fire safe china balls and fitted them with large bulbs.

Hi,

Have you actually tested the ball for flammability? In any reasonably civilised country I assume there would be codes regarding the combustibility of lighting equipment. Even if not, you can usually get spray-on fire retardant, and it might be a good idea to give it a dousing anyway (does smell of cat's piss, but it stops things catching on fire).

I once melted a big hole in a polyboard with a 2.5K HMI...
