Any leads on where to get light fixtures like this in kochi?

Same as the title, Any leads on where to get light fixtures like the ones below in kochi? Rental or purchase can be fine, it's for a short film shoot. The pictures below are flameproof factory lights. It need not be flameproof, but the look should be like the ones below. Very gritty, bulky and should remind of lights used in prisons or asylums. Any leads/contact regarding factory lights would be huge. Thank you!
