Help finding a 120v led

I am making a lamp from wood and resin and want to put a light inside to shine through the resin. I can’t seem to find a 200 ish lumen led with a rocker switch I can mount on the outside of the lamp so they can turn it off and on. Does anyone know where I should look for something like this? I would prefer somewhere in the states as I don’t have a month to wait for it. TIA, Tim

Wellp, you can gut a LED version of a “40W” appliance bulb for the innards, and use one of those inline switches to splice into the power cord.

I don’t know what the space requirements are or how accessible the emitter will be for replacement if the heat builds up.

E26 vanity bulb with socket and regular house switch would be an easy solution that would make replacements easy, but also frequent and necessary. Those bulbs are inefficient, get hot, and do not last in open air, much less a confined space with no air flow. However, you might ask how often will it even be used?

Dollar tree work lights are another option if color temperature and color rendering choice is something you’re willing to forgo. You can assume 6500K(cold, bluish white) or 65CRI, but it’s going to be all over the place. The good news is you can now supposedly order as few as 4 of the ones I see on there now. Used to be you had to order a whole case of like 48 or 84 or something nutty like that. They’re like 60 lumens so 4(which you could place in 4 directions) would be 240 theoretical lumens. One of them says “X lumens” lol so I have no idea.

You’re still going to need to power them, as they take 3x alkaleaks. You can just power them directly with an AC to DC 4.5V wallwart if you can solder. Depending on what wallwarts you have available, you could get little CC buck/boost converters to power the COBs directly. Probably easier to just use the shitty little driver they have in there and just solder your wires in the alkaleak bay. But lets say if you did have a 9V or 12V or 18.5V laptop charger, you could get a little CC(constant current) buck converter to drive the cobs directly. This would give you the opportunity to put a dimming knob in the mix.

Thanks Lightbringer,I didn’t know you could take them apart and they would still work.

Thanks Robin,I found a lamp socket with 2 circuits and that will solve the switch part but you brought up something I didn’t think about, heat. It is an inclosed space and it will double as a hidden stash place. That’s why I didn’t want to go with a bulb but it looks like it will be the easiest. I see on Amazon they have a .5 amp 50 lumen. I will get one of them and see how much heat it produces. Thanks for the info and heads-up about the heat.

Yeh, just gotta be verrrrrrrry careful.

Some might have discrete chips on a framework, others a COB-on-a-slab, you can hunt around and look through the “bulb” to see which kind it has.

200 lumen should be the equvalent of a 25-watt candelabra bulb (looks like something that goes in a chandelier) You should be able to find them pretty much anywhere if you dont like those…

they will but they can be hazardous

for instance it may be that all metal exposed after disassembling, is live with 120VAC

you will also have to be sure it does not get too hot

heat sink fins will still have to be exposed

and it will not be waterproof unless you make it be
