Bayonets are only used for specialty bulbs as far as I know. Normal bulbs are E26, both incandescent and CFL. LED bulbs also come in E26 but are very expensive so far. I have bought a couple of the 20 watt equivalent LED bulbs for my porch lights and a chicken shed. I just leave them on all the time. They only draw about 1.5 watts. They cost me $8.00 apiece, but have been burning continuously for over 2 years. They do not throw enough light to read by, but plenty of light to get by for other tasks and chores.

My yard light is a 200 watt HPS(High pressure Sodium). It has a photocell so it comes on at night. It is an E39. It is much brighter than the 200 watt mercury vapor lamp it replaced.

Cheers

Condolences for your lost...
I lost my suitcase on airport some time ago, still hurting..
Most people think that Finland does not have space program, but that ain't fact.
If you put your suitcase any of local bombers, your luggage never return to earth...

About led's,
I bought one of these ( 2W model ) and have to admit that it gives enough light (90 Lm) to read next to it on couple of yards radius.
I pursosely broke outer class so propably get something like 100 Lm out of it.

After my ESL's run out, I will replace all of those with leds..
Those looks something like hounder time better than ESL's, I took this with my crappy Android but should deliver idea.

Apropoo,
notice that my new blue light lures lot small birds.
Those seems to understand spaces as different areas, so not hitting windows or anything.
Well those eventually lures falcons, try to get you Brink some nice pics about local falcon pies.

Yes, that would be cool!

Nice view out the window. I like the woods.

Some local news. Verso Paper is laying off workers, probably about 175 or so. They have 3 paper machines in the plant, 1 modern and two which are about 100 years old. The old ones are for supercalendared paper, the kind used in advertising inserts. They say they are now too inefficient to be profitable. the plant is in Sartell, MN, a suburb of St. Cloud. The plant has gone through a number of owners in recent years, St. Regis, Champion, International Paper and now Verso. They were saying the demand for the kind of paper produced there is dropping about 3% per year. It is sad to see good jobs go away. Makes me thankful for mine.

Cheers

Like it too, kind of lot.
Unfortunately does not have it any more on workdays, dark when leave and same kind of when return....

Boss seems to like me, so not expecting change on this on this winter
