Information here about Weston's Music Hall opened in 1857. There is a long description of it here along with mention of the Chandeliers supplied by Defries:

The hall is lighted with five magnificent glass chandeliers, furnished by Messrs. Defries, the well known firm of Houndsditch. The central one weighs nearly one ton, and is eleven feet in diameter. Messrs. Patrick and Sons, of Westminster Road, were the general contractors for the work, which, we are bound to say, has been brought to so successful a termination.'
If Defries weren't using chandelier parts made by their own company, it might also be possible they perhaps used parts from Pellatt's? Another line of investigation perhaps? Pellatt's Falcon Glassworks were based in a similar area south of the now Tate I think or around that area.
I'm interested because it's fascinating glass of course, but also because I recently discovered my great grandfather and grandfather were Deptford born. Great Great Grandfather worked in Southwark and my great grandfather would have been around there as a kid when these light displays were being used
