DiCUNO 100Pcs 5MM Pre Wired 12V Warm White LED Diodes, 9.4 Inch/24CM Ultra Bright Light Emitting Diodes Assorted Color Kit Box for Circuit Science Experiment, DIY Lighting Projects

These are super handy, initially got them for a wood/epoxy project and I've used them for a little bit of everything from home decorating, Halloween decorations, etc Very easy to work with, especially when used with the battery hook up harnesses and mounting clips, but even without very easy to use and excellent brightness which can be adjusted depending on the amount of lights you write together. Well worth the price!

Great pack of LEDs even came with a couple freebies these lights are very well packed in a fancy box and look very good I would 100% recommend over all other lights I have they are super bright and easily to install since it’s only 5mm

These are pre wired with a resistor for a 12v power supply. They worked perfectly on my project, they are quite bright, and are a perfect white color. The white ones on the bridge in the attached photo were done with this product.

So I will start off by saying that by all means I am no expert. Making and using this was my first time ever creating a project that involved lights, more specifically micro led lights. So take this from someone who is not a professional throwing out a bunch of technical terms that the average person won’t quite understand, to include myself more than anyone. I spent hours and days researching the best method. I want to share this with everyone. The best advice is advice from person to person on the same level of understanding. (Noob to Noob). 1. The lights are great, bright and very durable. The price for all of these is amazing especially coming with pre-soldered resistors. 2. The description also says that all wire are copper. However, this is not the case (at least for me) as you can see in the 2nd picture, the left two are copper and the right two are silver. Only a handful of my 100 lights are copper. So that is a downside and is very misleading and disappointing. 3. While this is not mentioned in the description but other customers have shared pictures, my wires came in a paper type box rather than a nice plastic container than can be continuously utilized. It’s a bummer yes, but not a huge deal. Refer to my 1st picture. 4. Tip from me to any newish person to this hobby/craft. Almost everyone says or displaying using a 9v battery. While this does work, it is not the most efficient. I am currently using an Amazon Basics 12 23a battery. Much smaller and much cheaper. Also, I did try both batteries and even tried using AA, and a C battery. One thing I want to mention is that the 12v 23A battery is by far the best in terms of brightness and portability/small factor. While they may not last as long, weight and size reduction outweighs longevity of a big clunky battery. To reiterate, if you plan on getting these, go for the 23A battery with a battery holder like in my picture (all from Amazon). Using the 9v battery when connecting multiple lights was very dim. The same setup with the 23A was really bright. 5. If you wish to connect multiple lights to a switch and battery, the best way is to connect all the lights in a parallel method (positive to positive and negative to negative). Refer to picture for this as well. All black (negative) wires are connected together and all colored (positive) wires are connected together. This is the best method in terms of brightness as well. I tried this is a series connection as well and was very dim. Also when adding a switch, both ends need to be connected to the positive wires from the lights and positive wire from the battery holder. The negative wire from the battery connects to the negatives wires from the lights. 6. I also wish the seller would list more specifications regarding these lights such as the specific ohm resistor used, which is a 560 ohm resistor. Confirmed by color code on resistor (green, blue, brown, gold. +- 5%). Had to figure that out myself. Check image for reference (excuse the soldering on that, I’m new to this). Also I wish the seller would make smaller ones of these lights such as 3mm (these are 5mm) or even micro SMD (surface mounted device). Again these lights are great just some things to consider. In summary: 23A battery means brighter lights than any other battery. Parallel connect the led wires (positive to positive and negative to negative). Definitely a good buy by all means. Definitely recommend these lights.

Bright and good quality. Nice pre-wired leads for you project

I love these LEDS. They are useful for a number of various modeling projects and can be used for other projects as well. I use them for model railroading buildings etc...

Just used 2 of them. For gauges that had none. Work great so far. Not to bright. Thank you for extra 3 that were shipped.

I picked up the "warm white" LED's for illuminating my O scale buildings, and they are ideal for this. Running on ~12V the light is a bit bright for my application, but you can easily tone that down. That said, they are great bang for the buck and the leads are nice and long, which is awesome for wiring up on the layout.
