Re: Exploding bulb questions

I've been lighting with portable mp/tv lights for thirty five years and only had one occasion where a quartz globe exploded. Obviously you should visually inspect the globes and see if there are bulges or other imperfections that would indicate danger, and change them out when this is observed.

Fresenel instruments are safe by virtue of the glass lens, although in large instruments they are expensive to replace. I believe that all the new quartz units come with wire safety protection in order to get their UL listing. I know that K5600 had to provide such a system on their 800 Jokers to sell to Warner Bros. Studios, and they offer it as an option otherwise.

This thread is an important reminder that safety should be constantly considered, but that the incidence of this type of problem is quite rare, so it's often neglected as a concern.
