ageing |
|
Ageing is a very important process in order to stabilise the quality of a lamp after its production. Early failures due to broken or short-circuited filaments as well as air leaks can be eliminated by the ageing process. The filament will also be burned-in and will therefore reach a higher light value stability. |
 |
In general, the filament is subject to change within the first 16 operating hours, afterwards it will stabilise. All our lamps are being aged up to 16 hours at nominal voltage, and have to correspond to the catalogue data after the ageing process.
Additional ageing up to 100 hours can be necessary for very special applications, especially if very uncommon tight MSCd-tolerances have been specified. |
