DD00WM 20pcs Pre Wired Warm White SMD 3528 Led Lamp Light Set 12V ~ 18V 0.24W

Good product, easy to use and met my expectations, just wish the wires were longer than 6-7 inches.

Well made product at a very affordable price

Nice surface for gluing, easy to daisy chain multiple lamps by solder leads. Built in resistors makes hook up easyPlaced lamps under bridge over roadway to illuminate workers underneath, also placed in roof of tunnel for more light

Tiny wires make it easy to pull from the solder point.

These LEDs are prewired with resistors that are consistent with model train DC transformer output. I have several different types, including this one, I use for a variety locomotives depending on their mounting requirements. As simply wired in, they are single directional; i.e. only when the loco is moving forward or wired to come when on in reverse. I believe they can be bi-directional if you use a rectifier bridge. I'm satisfied with a simple single direction only. When used with HO diesel locomotives the light is extremely and consistently bright regardless of voltage input and looks the way a prototypical engine looks like at night.

With the interdiction of led lights my desire to add lights to my layout I tried other lighting options but the size and price I came back to these little led. You can place them anywhere without seeing them. I spent a few moments checking the leads for positive with a 9 volt battery and off we go. I use double sided tape to attach them inside my buildings and what a surprise these little lights do. My only problem was soldering longer leads on them the wire is very thin and the coating was tough. Other than that these lights are well worth the cost and I am counting how many more I need.. one thing I enjoy was the plug & play already installed resistor on the light. So easy to use no heat just light but I found out that a splicer plug from a different company works great to add leads to this light but don’t try to mix with company’s system light or power pack. Good luck these are great lights

These little LED's are just what I was looking for and they are perfect for my project. The small size is just what I needed to affix a few of these to (the ceiling, so to say....) of my indoor Christmas nativity stable. The small size of these is perfect and the warm white color temperature (the hue) light output is exactly what I was looking for and will illuminate the holy family beautifully. These will be powered with a 12 volt power adapter and I'll build a very small project box that will house a 5.5x2.5 female barrel jack to accept the 5.5x2.5 male barrel plug on the adapter and affix it to the back side of my nativity. These little LED's throw out a good amount of light so I figure I'll need about four of them for my nativity project. The LED's throw good light with 9 volts applied to them too, in case anyone feels the 12 volt is too bright. Or you could always diffuse the light too. Very pleased with these!

Quality build with long pigtails make using the product easy
