| So far this is just a Clanny, but in the Mueseler a metal chimney supported on an internal gauze shelf conducts the combustion products to the top of the lamp. |
| Like a Clanny, and the Davy before it, it acts as an indicator of firedamp, burning more brightly in its presence. |
| The Clanny gives more light than the Davy and can be carried more easily in a draught. |
| The glass on a Clanny was secured by a large diameter brass ring which could be hard to tighten securely. |
| It was not a practical success and Clanny subsequently changed the basis of operation of later lamps in the light of the Davy and Stephenson lamps. |
| Subsequently, Clanny incorporated aspects of both lamps and produced the ancestor of all modern oil safety lamps. |
