With the 10w Goodden in a similar bucket 12 sp.
Apparently similar habitats and there was not more than 70m between them but the 8w is a new lamp so I wonder if its true that the efficacy of UV diminishes with age and long before the lamp itself gives out?
I'm so fed up with tiny catches I'm changing all my lamps and investing in new batteries as some are 8 years old and took a hammering in the near zero temps in Sweden last month.
A snippet from UK moths blog: EU directives about lamps are going to impact on supplies of MV lamps so stock up if you use them.
Pic below is my only micro: Eulia ministrana. Just to cheer up Ina!
* 8w fixed vanes from Batty very easy to erect if not to carry and he says guaranteed to fire up every time, true enough so far.
