Fusing of Tungsten Halogen Studio and Theatre Lamps
A lamp normally fails at end of life by fusing of the filament. Often an arc then forms and as there is
little resistance to limit the current this rises to a very high value which if maintained can result in a
serious overload on the envelope and seals. This might result in the lamp shattering. A quick acting
high breaking capacity fuse must be connected in the supply line in all applications. Suitable types are
given in BS88 (IEC 269), IEC 127 or IEC 241.
