Superflux 4 Chip LEDs

All Customer Questions

Question

Would it be alright to wire 6 blue/white in series. Your calculator says so but it seems like it would be detrimental to the brightness level? I already have 6 red in a series and it looks great btw. - by Austin (Tennessee)

Answer

If the calculator says you can then go for it, personally I like wiring my LED's in parallel better anyway.

Question

What voltages are best for 2 brightness levels for running/brake light operation? - by Charles (California)

Answer

12v for full brightness, and a standard 470 ohm resistor will lower the brightness quite well for a running light.

Question

I am not sure how to use the LED Resistor Calculator. But if I wanted only to use one of these in my car what resistor would I need. - by Juan (Texas)

Answer

You should try the prewired superflux LED.

Question

Which two leads are positive, and which ones are negative; and how do the leads correspond with the polarity corner? Also, I noticed two of the leads have holes in them...what are they for? Thanks. - by Charles (Shreveport, LA)

Answer

The two leads with the holes in them are positive, the other two are negative. No specific reason for the holes other than to help identify the polarity.

Question

Which is brighter, this Superflux 4 chip or the High Power 1 watt? Sorry but the terminology is a little confusing to me. - by Steve (Dallas)

Answer

The high power 1 watt is brighter.

Question

I bought a set of after market headlamps for my 2005 magnum & each lamp has 3 of these lites. They burned out. I was recommended to you by a fellow car buff. How do I replace them. Do they just come out of the little plug in sockt? I can use the new ones that you have? Because what you have is exactly what I am looking for. As long as I can remove the old ones from the small fixture that looks like a bulb. - by Ish (Chicago, Il)

Answer

This probably wouldn't be a plug-n-play type of thing.
You would probably have to do some un-soldering and re-soldering.
We can't say for sure.

Question

ok I'm wantin to wire two of these in series to change the turn signals in the mirrors on my tC. It says I need a 68 ohm resistor which is not available. Would it be blinding to other driver's if I wired in 4 of these things? Even then it says I need a 1 ohm but one of the reviews said he used 4 in series so I guess it works w/o the 1 ohm resistor?

Answer

You might need to refer to our Forum, I'm sure someone on the Forum has done what you want to do.
Someone might have a better answer for you than mine.

Question

are these or can they be made water resistant/water proof

and can I wire just one by itself to a 12v power source without a resistor, or does it have to be more than that in order to wire them without a resistor? - by John (Las Vegas, NV)

Answer

These are "loose" LEDs. They are not waterproof and they do not work directly on 12 volts.

You should really check out our Pre-wired SuperFlux LEDs which are waterproof and work on 12 volts!

Question

How long is the life on these leds?

Answer

When driven correctly, this product can last 50,000 hours.

Question

do these leds need a resistor? if so how many and how long is the life on these? - by Frankie

Answer

Please use our LED resistor calculator:

http://www.oznium.com/led-resistor-calculator

At 12V, voltage drop of 3.5, and 80mA the recommended resistor is 120 ohm.

Question

What is the official viewing angle of the Superflux 4-Chip? - by George (Still on earth for t)

Answer

About 90 degrees of focused light.

Question

What is the Lumen rating on these LEDs? - by Tim (Souther CA)

Answer

These are approximate mcd and lumen ratings:

Blue: 1500-2000 = 4.7-6.2
Green: 4500-5000 = 14.1-15.7
Red: 2500-3000 = 7.8-9.4
White: 9000-10000 = 28.2-31.4
Yellow: 1000-1500 = 3.1-4.7

Question

If i bought the pre-wired onces, can you run those in series of 4 (blue) without resistors, and if so would it be less bright? if i got these, i could run a series of 4 with no resistors, but how do i connect the led's to the wire, would i have to run 2 wires? im confused about the 4 prongs. - by Jordan (Virginia Beach)

Answer

Pre-wired LEDs can not be run in series, since they already have a resistor built-in to make them ready for 12v. You have to run them in parallel. The four prongs are for mounting purposes. Two of them are hooked together for positive, two for negative. You only need to connect one of each. You connect wires with solder.

Question

Can these be wired to have 2 brightness levels for running/brake light operation?

Answer

Yes. You can do that with any LED.

Question

Can the prongs on the bottom be bent backwards so that the LED will lay flat or is there plastic in the way hindering this? - by Elliott (Raleigh, NC)

Answer

Yes, the prongs on the bottom can be bent so the LED will lay flat.

Question

can you show us a diagram about the 'series' wiring for 4 whites or blues in a 'series' without resistors?? can you show an example diagram?? thanks.. Jim - by Jim (St Louis, MO)

Answer

Wiring superflux LEDs in series is the same concept as normal LEDs. You just need to figure out how many to use in order to prevent overpowering the LEDs causing them to burn out. Check out our LED Resistor Calculator for that. All voltage info can be found on the Superflux LED product page.

Question

Do you have to wire both positive or both negative pin to make it work? would they work without resistor say 5 or more?

Answer

You have to wire at least one postitive and one negative pin. You can wire 2 positive pins and/or 2 negative pins if you'd like. It doesn't matter because both pins are physically connected. In electrical terms, they are "continuous". They have "continuity".

The reason there are 4 pins instead of 2 is because: the 4 pin setup allows the LEDs to have a uniform angle when soldered to a circuit board. It allows them to sit flat, which is especially important for LED brake lamps. The extra pins also allow more current to get to the LED chip.

They will work without resistors if you wire them in series.

Question

I see that you have UV wired superflux LED's but you don't have any unwired (loose) ones. Is there a reason for that? Do you plan on getting any? How hard would it be to take the LED out of the wired ones if you don't plan on getting any? Thanks, Cory - by Cory (Louisiana)

Answer

There is no good reason. We do not plan on getting any. It would be incredibly difficult to take the LED out of the pre-wired ones. If you can order at least 200 UV superflux 4-chip LEDs, we can get them for you.

Question

It is possible to wire 4 superflux in a series without resistors?

Answer

Blue, Green, and White can be wired with 4 in series with no resistors on 12v.

Red and Yellow can be wired with 6 or 7 in series with no resistors on 12v.

Question

What are the dimensions of these? I'm trying to determine how many I can fit at the end of a 1.25inch diameter tube - by Shay (Winnipeg)

Answer

Question

Is the yellow actually a yellow or is it amber? Im trying to get amber for a project but im having trouble finding them. - by Mykl (Bedford, TX)

Answer

That is subjective. Some would call it yellow, some would call it amber. The wavelength is 585-595nm. Maybe buy some to test and see for yourself?

Question

Do you have any data on the output brightness (mcd) of each color?

Answer

Blue: 1500-2000
Green: 4500-5000
Red: 2500-3000
White: 9000-10000
Yellow: 1000-1500

Question

How exactly do you wire these? Where and what resistor(s) are necessary? - by mike (Dover, PA)

Answer

There's 2 positive and 2 negative leads on each LED.

How many resistors? - Depends on a lot of things. Usually you can put one 150 ohm 2 watt resistor for each LED (on the positive leads).

It is usually much better to just wire them in series on a circuit board and avoid resistors, or use our Pre-wired Superflux LEDs.
