RULES (updated 01/22/25)

Be respectful: no harassment, hate speech, bigotry, and/or trolling. To be concise, disrespect is defined by escalation.
Encourage conversation in your OP. This means including heavily implicative subject matter when you can and also engaging in your thread when possible. You won't be punished for trying.
Avoid controversial topics (politics or societal debates come to mind, though we are not saying not to talk about anything that resembles these). There's a guide in the protocol book offered as a mod model that can be used for that; it's vague until you realize it was made for things like the rule in question. At least four purple answers must apply to a "controversial" message for it to be allowed.
Keep it clean and SFW: No illegal content or anything gross and inappropriate. A rule of thumb is if a recording of a conversation put on another platform would get someone a COPPA violation response, that exact exchange should be avoided when possible.
No solicitation such as ads, promotional content, spam, surveys etc. The chart redirected to above applies to spam material as well, which is one of the reasons its wording is vague, as it applies to a few things. Again, a "spammy" message must be applicable to four purple answers before it's allowed.
Respect privacy as well as truth: Don’t ask for or share any personal information or slander anyone. A rule of thumb is if something is enough info to go by that it "would be a copyright violation if the info was art" as another group put it, or that it alone can be used to narrow someone down to 150 physical humans (Dunbar's Number) or less, it's considered an excess breach of privacy. Slander is defined by intentional utilitarian misguidance at the expense (positive or negative) of a sentient entity. This often links back to or mixes with rule one, which implies, for example, that even something that is true can still amount to what slander is trying to achieve, and that will be looked down upon.

I have an offgrid solar system and have been wanting to do improve on lighting situation for a while. Got tired of dealing with rechargeable led lanterns burning out and 5v usb bulbs providing just enough.. So, I Made my own offgrid lighting fixture with replaceable led a26 bulbs. I started with a cheap single bulb hanging fixture, cut off the ac outlet end, wired on a 12v car plug, and screwed in a 1-to-3 a26 bulb adapter to get multiple bulbs parallel on the same fixture.

It plugs into my 12v solar system through a car cigarette port plug. I would like to get it on a dimmer at some point but this is sooo nice already. One of the few things I missed was the luxury of good home lighting. It took awhile to figure out a solution that worked.

I was thinking instead of a dimmer switch, maybe power it with a manually adjustable usbc-pd cord. The bulbs are 12-24v. I'm not sure if adjusting the voltage would make it brighter like how I'm expecting though? Is it 6w no matter if 12 or 24v? Might be a fun experiment. Theoretically it's currently consuming 18w to give me afequite home lighting which is about the same as a laptop on at idle. Very nice!

Are you doing some sort of dc/ac inversion? Why not use standard rv or boat 12v lighting?

[–] [email protected] 2 points 2 weeks ago* (last edited 2 weeks ago)

Its 12v dc from batteries straight to the bulbs. They are meant for 12v-24v dc in. Ive never been in boat or rv so I don't know what kind of lighting they use. The 12v e26 led bulbs say they are for RVs and boats so IDK what the difference is. I did what I wanted to do with the voltage and connectors I was familiar with. My other homes had e26 bulbs so why not this one just for 12v? This way I can use the fixture with Car battery or jumper pack battery with a cig plug connection.
