Are Piranha LEDs All They Are Cracked Up To Be?

- In this video I am taking a look at a novel type of LED called - I think - Piranha Superflux LEDs. These specific ones seem to be neutral white and have a forward voltage of roughly 3.1v and a relatively wide beam angle. They are supposedly brighter than standard 5mm LEDs but I have no real way of testing it.

I used to hear a lot about Piranha LEDs, but it's been a while. Thanks for doing the breakdown.
i bought some piranhas out of curiosity, tested them and never used them since.
Definitely worth testing this with a lux sensor (easy to find cheap i2c ones like the bh1750). A lot of LEDs have different color spectums and focus, that changes the quality and throw of the light too. I would be interested to know what your impressions about the difference in quality of the light? When used as a flashlight, vs for reading, etc. Love your videos!
I used to use these a lot a few years back, and then they were much brighter and focused than the normal through hole LEDs you could get. Also have some Red, Green and Blue ones which were compact and worked well to replace single colour downlights, although they didn't mix the colours that well close up. But now I think things have moved on, and most 5050 SMT LEDs are just as good and readily available, and the WS28nn ones have pretty much made the RGB Piranha ones obsolete for me now.
The red piranha will easily handle 100 mA, used 5 of them to make a 'strobe cube' for the back of a friend's electric wheelchair machine
As someone with zero background in any of this, simply looking to modify a motorcycle tail light with brighter lights, this was really informative. It was very easy to follow your descriptions of the math behind this stuff. Subscribed!
Nice clear explanation (and LEDS!). I bought some because of the cool name. 🙄 I haven’t put one in a project yet, the 5050 or 1206 tend to dominate.
They do dominate but I have not made a board using SMT LEDs yet - I've been busy AF
The color temperature looks a lot different between the two. The regular LED looks much cooler, leaning towards daylight white. That also gives it the appearance of being slightly brighter even with the lower current. What if you were to measure the brightness of each with a sensor to get a better value of actual brightness? Maybe a standard photoresistor or an ambient light sensor like the TEMT6000.
Always good to have choices and for the price might be fun to play with. I like the low profile. I have used 3mm LED's for that reason when I just need an indicator.
Hi. What you are missing there is the zooming, magnification radius of the light wave. The pyranha zooms out the light like a dome compared to the 5mm led that focuses the light a bit similar to a laser, putting more light into a narrower spot.
They are about the same lumens.
You can use a light spectrum meter for lumens output by measuring close to the led. So the result is 99% equal in lumens. Piranha lighting with a small increased power. But is not efficient in power consumption. The 5mm led is the winner in power efficiency for the microamps consumption. But not much difference. Few nanoamps means nothing in electricity.
The 5mm LED would be in the milliamps not microamps - a typical 5mm led needs a few milliamps to have a reasonable light level
I use piranhas for the lights inside my car, they have a nicer white and as you showed they diffuse nicely, especially when you have an array of them since they make a fully closed grid, on a normal breadboard they butt up against each other and don't make dot-lights like normal LEDs
Dump 50 to 60 mA or more into the piranha.
Cool.
Would linking the pairs of legs of the Piranha LED before using it in the test rig work? That way the whole thing would be tested it may balance the system? just a thought.Never found a use for them, but I do like a good old fashoned LED. 👍👍
The legs are the same connection internally, so they are already connected together
Having just bought some Jan 2024 they are listed at 3.1v and current of 60 to 80 ma. That would be a lot brighter! Thanks
They seem like they could have some use. They won't replace a flashlight though
Can anyone help?
I am looking for a LED with 2 led's in it without common anode/cathode, just 2 led's in one package with 4 leads.
This sounds like an XY problem - share what you need it for and what your goal is and people will be able to help you easier!

Essentially I need 2 strings of leds on mains voltage. I am using a PID controller to power a heater and I want one string in red when the PID controller is powering the load and another string in green when the load is "off". PID has a relay 2 way relay that activates as the output is on and off. The load is on SSR output and not connected to the led strings.
I have tried using 2 separate strings but space is reduced and there is half of the string on each color. If I could have dual leds in single package that would be great since there are more lighting.
Using 3 lead leds complicates things since I cannot series them and need to paralell them instead.
Thanks
Your video is helpful. This other one gives a better idea of coverage when he holds each LED further away from his work surface. It is a video from 2012: th-cam.com/video/g7OtLVk5yiU/w-d-xo.html. It would be interesting to see a flat top 5mm and 3mm vs a Piranha as I think the wider dispersion of a flat top might be more similar to a Piranha. Also an 8mm straw hat would be interesting to compare when driven at 20ma since it takes up only a tiny bit more space vs a Piranha @7.62mm and also has a wider dispersion.
Useful video, thank you! :)
i love LEDS lol but im too poor to afford anything and when i do get money i buy stupid shit and get ripped off on ebay sometimes lol but im learning lol. ive been buying shit off ebay for years now so i know what to look for lol but anyways thank you for your videos they do help me out allot and i hope nothing but the best for you god bless and have a great day
Strange, I thought that these piranha led's are supposed to be about 80mA max current...
Yeah, I thought the purpose of the extra legs was to sink more heat so it could be driven harder.
also ive learned my lesson not to buy the cheapest stuff you can from ebay and think it will work lol because most of the chepaest shit on ebay is junk but you do find good stuff if you know what to buy and what not to lol well thanks for the video gave me something to buy lol
I DON'T KNOW
This was a lot like the " Does MacIntosh apple cider get you drunker than Granny Smith apple cider" test. You just keep saying "I don't know", but forget to stop there.
Won't work in bread board
It totally works in a breadboard - why would you say that?
Not gonna buy. Thanx a lot!
you clearly put some effort into the thumbnail, also into the title so why didn't you spent 10minutes googling about perceived brightness by humans? if you do your homework maybe you can get a factual video instead of your "ignorant opinion", I do have to use the word ignorant because if you done your research the outcome of the video would be different, do your homework!
I checked your TH-cam channel to see how you presented it, but I didn't see anything :( I thought you would show me how it is done!
this is a fail! Jeremy Seitz mentioned one of the many sensor you can use, some cameras have them built in, but they need to be properly used.
