Piranha Super-Flux vs high brightness 5mm LED review

[ElectroElvis]

Hello,

IF somebody is interested to check out the difference between standard high brightness LED's and Piranha LED's feel free to read little further or skip to my webpage: www.electroelvis.com

For actual test I have used two 5mm high brightness LED’s and two Piranha Super-Flux. All four are cold white color except one Piranha is warm white.

LED’s came from website www.hebeiltd.com.cn which they have quite low prices compared to others, only catch is if you buy low quantity they charge you “penalty” for that.

For input voltage and current refer to the picture above, lettering in the RED provides that data


All LED’s are on breadboard with 5V Voltage regulator on input. Power source is 9V battery and each LED has dedicated resistor to come as close as possible to max potential.

More picture's from test and video can be viewed on next two links:

Yeah, piranha LEDs are really good.

I ordered 50 of the red, green, blue and RGB piranhas from www.hebeiltd.com.cn about 3 years ago.
All of mine have a viewing angle of 110-130 because i wanted to use them for illumination.

I put quite a few in my car to replace various lamps and around 9 of them to replace the interior light.

I also managed to take some nice switches apart and replace the lamp with RGB piranhas.
Hollowed out the first switch contact module and used it for the 4 RGB led connections.

I will definetly order some more in future, yes there were also Piranha up to 140° viewing angle but at the moment I only needed ones with narrow view angle.

Very nice trick with switch. Do you limit power to them or you illuminate them at full brightness, in this case is it too bright to "find" switch?

Fantastic blog, excellent content there. Subscribed!

Currently around 8 of them are connected up to a micro controller driven 40 channel array of DACs in my car.
I made the DAC array controller board many years ago before i really knew about PWM.
It wasn't the best solution but it works. It varies the voltage between 0-5V with a resistor in series with the LEDs to limit the current to 50mA. So the brightness can be controlled by the DAC value.

Maybe a bit of a dumb question: is Pirahna some specific LED manufacturer or this name refers only to the shape (square base and 5mm lens, wide viewing angle)?

In Poland for example this type of led is commonly referred to as "superflux".

They're also called UFO leds.

To answer a question: Originally it was called and still is called SuperFlux that is trade name from Philips light department. Others call it Piranha, HighFlux, UFO...  All those names are just describing same product.

LED diode with very high output, lower thermal output at same ratings then standard LED's better mounting and anti movement since it has four pins.

All in all it is the same product just different name. Hope that this answer's your question.

Just a little candy for all: SuperFlux is trade name from Lumileds, which is now almost 100% in Philips ownership but before that it was 50% 50% between Philips and Agilent
