Didn't do a  jack o lantern this year. Just put up some strings of lights in seasonally appropriate colors. (and connected to the controllers I use for Christmas lights)

A circline would be cool  lighting for one.

Yoink!

Liberated these brand new TL-Ss from the recycle bin at a hardware store near me. I saw them, and literally made a little jump when i figured out they were warm white. Although these were not uncommon in trains and such, finding them in consumer hands was incredibly rare. So i really wonder what person had this bunch of tubes stashed away.

I have no use for 8 of these. I'm gonna save two, for use with a Stabilux-style ballast (incandescent lamp serving as a ballast and to fill in the gap in red light emission) and one spare. Should serve me for the rest of my life.

The others i have already offered for free pickup on a different forum, but keep your eyes open - if no one there wants them, i'll give them away here.

I also took an 8w 830 tube (since i actually use 8w fluorescents to fill in dark corners) and a 4w 640 because they're cute and it's nice to put them in my battery operated fluorescent lamp.

Yeah maybe, they are actually replaced in all the underpasses down the road in the 2nd link.

These could be maintained by the city of LA rather than CalTrans as the overpass is above a city street. If an agreement is made, CalTrans can hand over maintenance of lights that they installed that light a city street over to a city.

Changing of the seasons...

Over the past few days been putting up Christmas trees & stringing lights on them in the familyroom.
Also took down my 'flag of lights' in that room.

Other than things like marking boards to cut, I rarely use pencils. Much prefer pens if I need to write something.

As far as what pencil, I don't care...a pencil is a pencil to me. I'd just buy whatever's cheapest.

Today's cat lamp: Deluxe HPMV (Philips HPL-N Deluxe, 50w).

Phone's just set to auto everything, but no AI retouche of course.
She's  looking up at me, because i had the audacity to stop petting her for a few seconds.

Do contribute with your own pets and lamps!

I made a mock-up for adding lighting to our show case with scientific instruments (spot the 90w sox! That's my private property), taxidermied animals and historical media things i found in the building like video tapes and diskettes. It's always been very gloomy because the hallway is not that bright. If you walk past, you cannot look inside due to the glare from other lighting and from outside.
I have gotten enough 'Yes, that's good!' reactions, to now start making a full budget estimation.

I am pretty happy with how it looks. 2700k instead of 3000k LEDs would have been nice, but because the hallway light may be converted to 4000k leds at some point, the 3000k you see in this picture will stand out nicely and 2700 will definitely look too yellow.
Spot lights would have been most eye catching, but since there is no room inside of the show case to point them at the front of the artifacts, and shining them through the glass would cause tons of glare, i opted for LED strips.

The LEDs used are strips with Epistar SMD2835 ones with a CRI of >90 that can run at a maximum of 40mA a piece, though they will not be running full blast probably. In total, there will be about 16 meters of LED strip in the entire show case totalling close to 160w - one strip of 50cm below each shelf, hidden from view and glare by a piece of angled aluminium. Everything will be dimmable with a random PWM dimmer i have, and the power comes from an old server PSU. The main 12v bus will be inside the closed-off cabinets that the show case is sitting on, with a spur going up to each set of shelves.
The extra light is very welcome in the gloomy hallway, currently lit by 1 56w 830 fluorescent per 6 meters i think.
