Buddle was involved with the introduction of the miners safety lamp invented by Humphry Davy being involved in the earliest discussions with Davy in August 1815 and providing "fire-damp" samples for experiments in Davy's London Laboratory.

Xenon arc lamp which poses safety concerns. If a lamp is dropped or ruptures while in service, pieces of the lamp envelope can be thrown at high speed.
