100pcs Pre-soldered Micro pico Litz Wired Leads Blue SMD Led 0603 + Muti-Resistor NEW

These are great LED's. They are the same size as Evan Designs "Nano" LED's at a fraction of the cost. Enough resistors are included to wire each individual LED on its own power source. The resistance values are as follows: 9.1v - 14.4v = 675ohm 5.1v - 9v = 359ohm 3.5v - 5v = 120ohm. These values are a tad bit over the needed resistance to prevent blowout, so a safety margin is built in if you decide to use them. ALL LED's lit up without issue One bit of advice: 1 LED appered to not light up. This was due to the bare portion of the lead being broken off or not exposed. If you have ever worked with or tried to solder magnet wire, then you know what I mean. The insulating cover must be SCRAPED OFF to expose the bare wire underneath. All in all, excellent value from an excellent supplier. A++

These exceeded my expectations so far. The lead wires are super secure and LEDs are bright. Perfect for tiny spaces.

Super Tiny. About like the tip of a sharp pencil. Flat. One side much brighter than the other. Polarized and comes with current limiting resistors. Very nice.

The lights work well and produce a bright warm clean light. They used a stiff wire that interfers with mounting in tight spaces. Like HO scale headlight housings. I was able to use them in number boards more easily and they will and do work well in hidden spaces. The 0603 light head is too big with the wires attached. They are also mounted in a small drop of resin which may make them waterproof and better suited for lighting drones. They various colors are well suited for signal heads. I won't be purchasing the white lights again due to room constraints but not do to any other issue. They seem to be good quality In

Amazing micro led. I used for my airplane model 1:200 scale and looks amazing.

These lights are awesome. I use them all over my HO layout for light poles, also great for ditch lights on locomotives because they’re so small. The wires are insulated so they won’t short, they do need resistors installed but they come with them!

Update 04/23/2020: Wanted to update this review as I'm buying the $30 multi pack now, so I added a few more pics to this to show how this looks on my RG Sazabi and my RG Nu Gundam. I've since learned I prefer using a 3V coin battery rather than an old iPhone cable. Since these SMDs are made for 3v I don't have to add a resistor to my circuit. In case anyone is wondering I didn't have to mod my RG Sazabi at all for the SMD to fit. All I did was used magnet wire (thinnest wire you can get) and since theres empty space within the cockpit in the head, all I had to do was secure the SMD in there. The photos I used are before I tried the magnet wire and 3v coin. I'm still learning and I'm getting better at this. The RG Nu Gundam I used a pin vise and drilled a small hole in the clear plastic piece used for the eyes and was easily able to put it in and run the magnet wire. On a 3v coin battery alone I was able to have the eye powered up non stop for about a full week until it started to lose luminance. Building a custom MG Sazabi now and playnning on light everything up with these. First Review: Finally got around to using these today after a few months sitting in my drawer. I build Gundam models and since most kits dont have the ability to put a normal LED in them I had to resort to this microscopic sized SMD. I'm quite surprised at how bright this thing is for it size. The kit was straightforward all you have to do is find something to power it. I used an old iphone cable using only the power and ground. I tested the voltage using a multimeter and it puts out 5V. They kit includes a bunch of resistors that vary in voltage and since I have a 5V power supply all I had to do was simply choose the resistor that was in the 5V range. I have no experience with electronics just did a little research. I don't know how to calculate what resistor I'd need if it wasn't clearly labled in this kit. However, seeing this work has sparked my curiosity and now I want to learn more for future Gunpla's i create. This is probably the easiest circuit to create. Having this presoldered and resistors clearly labeled with which one to use for your power supply made this even easier. Note: I'm clearly not done finishing up my current setup in the picture. I plan on running longer wires and electric taping or covering the exposed wires. This was just me taking a pic that it works.

I bought this for model lighting and what a pleasant surprise. They are almost microscopic but provide a lot of light for the size. Only requires about a 1mm hole. The positive lead has insulating varnish. There are separate sets of resistors included for a wide range of voltages (3V to 16V). They are a warm color temperature (estimate 2800K-3000K). I use a 12VDC bus for lighting. Solder the resistor for your voltage, drill a small hole, add a little PVA to hold in place and done. Thank you, seller.
