30pcs 12 Volt 5mm Warm White LED Lights Emitting Diodes Pre Wired 7.9 inch DC 12v LED Light Clear Lens Small LED Lamps

I ordered these to install into my buddy's Remote Controlled VW Bug build. They look much better than a bright white led, for the more period correct look that we wanted for his rig. The lights came in a zip lock style bag, the wires are not the normal red and black but they do mark which is which.

I use these Soft White LED's for lighting up my model railroad buildings on my O Scale Layout. I also use a AC to DC 12 volt regulated Buck & Boost with these LED's so there is a constant 12 volts for my 18 volt AC transformer accessory output voltage.

Price is right

Good size and brightness and the light from the diode is stable. However, this is the first 12V LED that didnt work on 12 VAC as well. it only had a weak flicker on AC so I had to build a quick converter for my 12VAC train transformer. not a big deal, but never experienced that before with 12 V LEDs. (I know the description said 12VDC, but usually they work on 12VAC as well, at least that was my experience). still worth the price for me, and especially for someone who needs a solid white LED, especially for car/bike/boat applications.

When I first installed them, I thought they were great. Nice and bright. But after several dozen hours of operation, I realized that they lost brightness over time. I'd estimate that they are now only 70% as bright as they started out when first installed. And I didnt realize it at first. I installed the first set and realized that they didnt seem as bright as they should be. So a year later I decided to add more to the project (from the original purchase). When I tested the new ones, they were significantly brighter than the installed ones. I assumed I had power supply or connectivity issues with the first install. Now 2 weeks after adding the new, brighter bulbs, they too are now as dim as the first ones I installed.

They are nice and bright at first as expected. Just do not last very long and start going dim way too soon.

I had been looking for loose LEDs for small projects that LAST longer than a few months. And by a few months, I mean they keep their initial brightness for longer than a few months. After trying a couple other brands, I tried these LEDs and was very disappointed by them fading on brightness in only two weeks of 24/7 use. They still produce light, but not near their initial brightness.

First off, I'd like to start with the fact these things seem to be assembled, or soldered, with tree sap or something extremely weak and inefficient at its job. Look, they're small LEDs with wire as thin as an atom... Handle with care. But in a project using 6 of these, and then having a result of 4 of the 6 fail with the wires just coming right off before the job is done? Get out of here! Also, the warm white variants.....seriously....? Yellow is considered warm white? No.... Yellow is yellow. Warm white is white with a slight orange/red/yellow tinge to it on the wavelength spectrum. What I got was a funny looking yellow LED. Lolll Pass. The rest are not going to be used. Moving on to a better component. These are pretty much useless.
