Update number 1. Still an hour from dusk. Just thought I'd let you all know a few thing. First it runs fine in the rain. Never occurred to me that topic never came up in my research. Secondly 1/2 acre unit came with 1 mosquito attractant. Cool. I'll wait to use though. Do a before and after thing. Lastly see attached photos on my comment for bulb model numbers I snapped a shot of out of the manual. Says they should be replaced annually fyi. Been on 3 hours still no zaps. It's day light and raining. Counting down the hours to dusk.
