Much better than expected

The all around quality (including packaging) was the best I've ever seen for LED's. Specifications on the packaging were dead on. Some PPL have brought up the fact the legs were short - their not 'that' short, maybe only 4mm shorter than regular leds which didn't effect me since I snip off the difference anyway. The light frequency is nearly invisible - at HALF the amperage per led ~10ma photo sensitive materials across my living room boomed with brightness akin to having a florescent black lamp on. I tested most of them using a lab power supply and had no defects. 14 of the LED's at only 60ma (a fraction of the amperage their rated for) was enough to illuminate anything in about a 3rd of a bedroom when placed up high. My personal project was a 3D printed (with glow filament ) Fallout NukaCola bottle and these UV LED's made the glow highly reactive (great!).

Very bright, great buy

I used these LEDs to make fishing glow sticks for night fishing. They are very very bright and are very easily seen on the water. My expectations were exceeded. I didn't expect the to be as bright as they are

Which resistance to use, read this!

The minimum voltage is 3.1 V w/o any resistor, use 50 ohms from 3 to 4.5 volts. Use 100 ohms from 5 to less than 6 volts. Use 150 ohm for 6 volts, 300 ohm for 9 volts, 450 ohms for 12 volts, according to formula R (ohms) = (V - 3.1)/0.02. Warning: You have to mind the resistor power dissipation rating. That is, if using discrete, axial resistors, you may use the 1/8 watt until 9V, then you must switch to 1/4 watt resistors (bigger) until 15V. After 15V, you need to use even bigger 1/2 watt resistors. You'd be wasting a lot of power after 9V!

The 395 nm UV light is good enough for the home made UV Lamp I was working on. I used 54 LED with a 3.3v 1A power adapter, I might have gone over by 4 LED, but my project is working. Made a UV lamp to dry PCB ink.

They make my projects shine

Nice LEDs, bought for a UT fan to light up a license plate me and my friend made for her Jeep from my home built CNC. So far all have worked and can in a bag with specs. 3rd time I have bought LEDs from CHANZON and have not been disappointed yet. Thank you for a great product.

So far so good

Look, I'll be honest and say that I haven't tested every single 100 of these various colored 5mm clear LED diodes but they've functioned as expected so far. In my specific case I had to replace one on my PC case for the HDD LED and it works wonderfully after removing the old one and soldering the replacement one to the cable. This was the reason I got it and I can understand why you can't just go buy a single LED diode in this day and age. Thankfully the price for a 100 pack is well within the price range for fixing a single issue so I don't regret having 99 extra ones in storage.

Good product but consider what you're planning to use them for.

These are very bright LEDs and the color range is just as good as I expected. One thing I will note for other customers is because these LEDs are clear, the colors don't really "mix" you will have to diffuse them somehow if you want your project to appear as if it has one LED capable of generating many colors otherwise you can clearly see the beam of light from each individual color chip. If I were to buy again, I would probably look for diffused RGB LEDs. As a quick fix, I put a frosted finish on a few of them using some 120 grit sandpaper and that worked just fine. The front of the package indicates that the longest lead is GND, and even specifies the voltage to each positive lead. Red doesn't require as much power, so you'll have to give it a higher value resistor than blue and green. All parts arrive in a small plastic bag but surprisingly, I didn't find any bent leads. It would have been nice to only have to purchase 20 or 30 since I only had one project in mind for these, but the rest go in my parts bins for next time and it's okay to have extra stock.

Excellent Quality LED's

I first got the variety pack with samples of each colour, and then went back and ordered the 100pcs of each of my favourite colours to use in projects. Here's my quick summary of the colours so you can get an idea of whether or not you want specific colours to use for your designs: - Chanzon Orange = Nixie Neon glowing filament colour, quite red, very nice - Chanzon Blue = Bright vivid sky blue, excellent colour - Chanzon Pink = Bright Pastel Pink, very sweet romantic colour without being overbearing - Chanzon Yellow-Green = Bad; very dim brightness, ugly piss/highlighter yellow colour - Chanzon UV (Purple) 395nm = Dim brighness, UV blacklight colour, possibly good for niche special effect use - Chanzon Yellow = Bright vivid sulfur lamp yellow, almost orange, great for scale model construction vehicle lights - Chanzon Green = Super bright vivid kryptonite green, excellent - Chanzon Red = Super bright vivid Red, excellent - Chanzon White = Bright cold white colour, useful for neutral lighting or flashlight lighting - Chanzon Warm-White = Bright incandescent warm white, IMO preferable to the normal white which is sterile feeling

Good product, good price.

These LED's arrived on time, and the ones that I have used so far, have all worked just fine. I had several burn out, if that's the right term for a diode, but it was my fault. The current limiting resistor that I chose provided ~30 ma of current, whereas modern LED's need only 12-18 ma. Good product, good price.

Great lights, but watch the voltage!

Very nice lights. Ten of each colour, and each colour comes in its own labeled zip bag. Just watch out for the voltages... six of them were 3-3.2V, and four are 2-2.2V. I learned this the hard way... I was using the 3.3V power from my Arduino to test them. Everything was fine until I got to the orange. I fritzed three of them before I realised they were a different voltage. This is clearly labeled on the individual packages, so it's 100% on me. Other than that, the colours are brilliant, and the selection is great. 3V: White, warm white, blue, pink, UV/purple, green 2V: Yellow, yellow-green, orange, red
