When I use the overhead light I get too many bugs, not to mention it's not very pleasing. I was thinking of wrapping the post there in Christmas-style lights, but can you find those anywhere during this time of year?
Do you really need lights out there? We have a screened in porch with the exact same fan/light combo and we never turn it on unless one wants to read or if we have company because lights from the inside provide enough illumination, kinda like mood lighting. You might try to find a different globe with a yellow-ish color, not pleasing either but bugs tend to stay away from that frequency of light, or, try Home Depot, Lowes, or patio stores for those outdoor lights you hang out for parties like those red chili pepper shaped ones.
You can probably find those "christmas" lights around. There are actually some lights which are simply christmas type lights in a clear plastic tube to shield it from the elements I've seen folks illuminate decks with.
You can find yellow 'bug lamps' to put in the fixture at either HD or Lowes. My experience with those things has not been good. Yeah, the bulb is yellow, but the light then reflects off the siding (yours appears to be light grey or white) and the bugs show up anyway.
Think it's called rope lighting. You could spiral them up that post and make it look pretty cool. I'd suggest staining/painting that pole first for a more "finished" effect.
Did you see that kegerator thread ? You look like a prime candidate
If I do rope lighting down the post, should I fasten it to the post in any way (other than at the top and bottom - to keep the even spiral spacing), and if so, what would I use?
