microtivity IL185 5mm Assorted Diffused LED w/Resistors (5 Colors, Pack of 50)

These LEDs are bright, colorful, good value and add flair to electronics projects. Being diffused is a plus. I'd definitely buy again. I took off 1 star because of the resistors. It's great that resistors are included, but the wire leads on the resistors are so thin that they barely make a connection in my breadboard. If used in a soldered application, no problem, but I'm not so confidant on a solder-less breadboard. I'm using them in my project, but if I start seeing any sort of flakey behavior in my project, the 1st place I'd look to debug is whether these resistors are making a good connection.

Some of the LEDs had some imperfections, one made it into my project before I noticed. Not a big deal, but better quality control would have been nice. The included resistors are all the same value, but the brightness varies between colors. I used red, green, and blue in my project, and when using the same value resistor, the green is much much brighter than the red and blue despite having the same forward voltage as red. This is not really Microtivity's fault, but be aware you may need to tweak resistor values if you want the same relative brightness.

They are cheap little LEDs, work as expected, but they require a slightly higher current than most LEDs to get full brightness. This is to be expected of cheaper LEDs however, and if you only need a couple in series with the proper voltage source they are fine.

For the price, this is a good deal. We tested them right away and found that several of the LEDs were DOA. For the handful that didn't work this seemed reasonable. If you have a project that requires exactly this number of LEDs, just be aware before you buy!

These are lights. that light up. Hard to screw this up. They seem to be good quality. I have yet to break one either by physical crushing or separating the leads, or by frying it with too many volts (and I have tried).There is a decent variety of colors and a good quantity for basic usage. If you are building an array of LEDs then buy something else: consider buying in bulk. But if you just need a few LEDs to throw in a circuit then this is for you.

The first batch I got was really good. Nice bright colors and long leads. The second batch is vastly inferior with dull, muted colors and short leads. Unfortunately I thought I had found a good source as I go through a lot of LEDs but there is no consistency in the product delivered. Five stars for the first batch and two stars for the second.

Everything seems to be there. I haven't used any of the LEDS as of yet, but it got here reasonably quickly and looks like what it is advertised to be.

okay but takes forever to ship to earth
