It pulled in more moths than the 6 watt actinic I would otherwise have been using, but almost certainly less that a 125 watt white lamp would have. The main drawback I found was the price of the lamps and their ridiculously short service life. I tried two lamps and neither lasted much more than a year. I always keep a record of trap on and off times so I was able to work out the total burn time of each lamp and neither managed more than 200 hours, which is pretty poor. I believe it is the thick Woods glass envelope that shortens their life, by hindering the cooling of the lamp, leading to overheating. I now use a 22 watt circular, green actinic and it pulls in as many moths and species as the black MV, if not more.Mark Evanshttps://www.blogger.com/profile/02372785801699168219noreply@blogger.comtag:blogger.com,1999:blog-7553355011221187801.post-27871114515212590512014-07-04T21:15:23.768+01:002014-07-04T21:15:23.768+01:00Hi

The two nights I used an MV I was getting twice as many moths, of 70+ species, although a lot of the higher number of moths was taken by Heart & Dart and Dark Arches!<br /><br />One day in 2012 (in Bucks) I ran an MV and a 15W actinic adjacent to each other, with similar results (295/65 vs 117/48) and it was noticeable that there were some species that came to the actinic and not the MV.<br /><br />Hope this helps!<br /><br />Dave Davehttps://www.blogger.com/profile/00362910513148365379noreply@blogger.com
