DiCUNO 450pcs 5mm LED Diode, LED Light Kit Box 5 Colors, for DIY Project

I made a mistake. I put too many of these into a project. The clear LEDs are SUPER BRIGHT. I felt like a deer in headlights on a highway, and they looked like Hollywood at night. Just warning you in advance! I put the blue ones into a sign with 2 generic batteries in July and turned them on, and it's December. Still going. Great for projects! These are the 5 mm standard size. You want long lasting, bright color LEDs for your project? You're in the right place.

My students used these to make light up greeting cards during a math and science project. The results were fantastic.

No complaints with these LEDs but they are very, very bright. Make sure to pick an appropriate resistor. At 5V I felt even a 2.2K ohm resistor left the LED still a bit too bright for normal use. They do not run hot or anything and seem to hold up well in various projects I've done, so it was a good deal. So far no duds in the box either. I would say these are somewhere between clear and diffused and don't fit in either category. The color quality is consistent across parts.

These are listed as Super Bright LEDs, this is definitely a correct description, especially the green and white colors. All other colors are quite bright as well. These are listed as working at 20mA, but I've found they are almost as bright at 10mA and acceptable for most uses at 5mA. The green and white ones are actually usable at 1mA if just needed as indicators for something indoors. It's been quite a while since I restocked my LEDs, I was surprised how much the brightness has improved over the last decade. Not sure on the longevity, but planning to use these at half of their rating (10mA instead of 20mA) or maybe even 5mA, so expect they should be good for a long time.

Decent quality, nice container. Nicely labeled. Blew up a few in testing but that was my fault. Tolerances are as listed in the material and are fairly accurate. Would buy again.

Nothing to dislike, these LEDs are super bright. They are the best bang for my money or your hard earned $$$. I designed an LED sign that required over 500 LEDs of varying colors that are connected in a series parallel array at 12 volts and 15 milli amps. The forward voltage specs had a Vfe range which meant that my design calculation to make the LEDs at the same brightness at 15 ma could vary. I connected 4 LEDs in series and found the average Vfe at 15 ma. This average Vfe remained constant given another 4 sets of 4 LEDs in series. Perfect! I ran out of red LEDs and needed to reorder another bundle box of LEDs. Amazon raised the price and a quick email to the mfg regarding the increased cost. The mfg refunded the difference which made this a 6 star rating. Thanks ... The LEDs were packaged quite nicely and the empty plastic container made for a perfect storage box for my current limiting resistors.

Perfect to fix Christmas lights.

good

these will do quite nicely although there are far too manny of them for my life time

- umfangreiches Sortiment zum sehr guten Preis - hohe Leuchtkraft der LED's

Every one worked so far.
