    Brightness & Price... All package fully operational. Used them for decoration with 2 AAA batteries (3Volts).. Even had to use 120ohm resistor for each led on some projects to reduce brightness in pitch black ambient light. Very low power consumption. None that I can remember. Although there should be bigger packs, with even better prices available.... Read more

    These little LEDs are perfect for any small lighting projects you plan on doing. They seem to have pretty good build quality, strong leads, and are relatively bright. So far I haven't had a single one burn out, so they seem to have good internal strength. None at all. None at all. For only 1.45, you might as well buy a few! I always tend to run out ... Read more

    Very bright leds if compared to their size. All leds inside the package were fully working no twisted legs or dead ones. Nothing at all. Maybe little lower price or bigger amount of leds. These leds runs best at 3,3v. I measured brightness with that voltage and it was 3840Lux @ 10 cm. I tried 5,5v but leds color goes weird and light was going very dimm.... Read more

    These really glow bright blue!. I have been using these in guitar pedal projects for a while now and have not had any failures. They seem to be well constructed. The 5mm size is a handy size to keep available at my work bench. They have a very clear lens. They also have strong metal leads which do not bend easily (which is a GOOD thing!) None that I ...

    Very cheap and insanely bright. I can use them for building my own growing light. It's cheaper than buying LED lights from local electronic store. Shipping time approximately 3-4 weeks, not a big deal because I only have spare time on weekends. Now I'm building LED matrix using these LEDs and will post picture after it's done. None, seriously none. ... Read more

    They are definitely some of the best LEDs per unit cost I have come across! I have a very large assortment of 5mm LEDs for my projects, and because I have to change them out frequently, I needed to have LEDs I could cut to custom lengths, and these fit my needs perfectly! They came packaged securely in bubble wrap and were all in perfect working order ... Read more

    They are very bright, even if it is in an iluminated room. The price is very good, since with the same amount of money I would be able to buy just one led and a half where I live Nothing that I could think of. I couldn't test the durability but i think it will not be a problem It's good to have big quantities of spare leds. You never know when you will ... Read more

The color is good and they give great light. Good for indicators and modding. - No datasheet. I don't know what is normal current of this LED, so i don't know what is normal brightness for this ...

    These LEDS are really strong... The price is unbeatable Quality is GREAT! i've ordered 40 ( forty ) of them and all worked well. The legs [ terminals ] have good size No cons at all, maybe that it doesnt come with data Sheet, so i had to measure the characteristic by my own ( voltage, power consumption, current, etc ) there are lots of uses, even in ...

    The price these leds is very good! All 10 LEDs work perfectly with a low current consumption. Work with 3 volts, but you can use a regulator lm3940 transforming 8 - 24 Volts to 3.3 Volts without problem and use the LEDs in the car battery that has a 12 - 14 Volts arrived in my city in less than a month! They could be slightly brighter. but beyond that,... Read more
