15W ASTRON UV-A lamp 45 cm SHATTERPROOF

refill lamp for many insect traps of Alcochem and Pest West series

SP stands for shatterproof, in which case a plastic sleeve is placed around the lamp. This means that if the glass is broken, it cannot spred.

Especially around food production, this is very importatnt.

About the UV-A lamp and their replacement:

There's still little or no awareness of the fact that UV-A light dimiminishes over time, and as a result, lamps are either not replaced or are replaced too late.

This will cause a fly trap to work less effectively or even not at all.
