DiCUNO 100Pcs (10 Colors × 10Pcs) 5MM Pre Wired 12V LED Diodes, 9.4 Inch/24CM Ultra Bright Light Emitting Diodes Assorted Color Kit Box for Circuit Science Experiment, DIY Lighting Projects

These are great for a small project, super bright and colorful with minimal amp draw.

These are perfect for accent lighting, I dont renber the drill size , possibly 3/16", the bulb just pops through the hole, works like a charm

We loved these. We used these lights for a fun little games for kids, toss a ball into the glowing bucket. Those lights took a beating!They are durable, bright, and easy to put together! We had over 50 lights wired to one 12v wet cell battery and several connected to a flasher. Perfect lights, loved the color of blue and look forward to buying more colors in the future!

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.

Work great love their pre wired

When I received these lights I tried them out only to find it was really dim. Then I remembered that it takes 12V batteries. I was using a AA battery. So, I ordered 12v batteries and the next time I tried them it was blinding. I was so relieved and excited. Just an FYI the size of the battery makes a world of difference.

Ready to go, perfect to use for projects without having to solder resistors yourself. Easy to tie into USB power or any other 12v source. Thanks, I will purchase from you again

The media could not be loaded. These work great with any Arduino build. Handling up to 12 volts.
