Slow Color Changing LEDs
These LEDs automatically and slowly cycle through the colors: Red, Green, Blue, yellow, teal, purple, white.
——–
Fast Color Changing LED
These LEDs cycle quickly through all colors.
**Note** These LEDs also cause other static LEDs to flicker a little as well. This effect is less noticeable if using the rechargeable battery upgrade.

Aqua Green LED
Slightly different than our standard green and a bit brighter as well.

UV LED
UV LEDs makes a nice deep purple (hard to see in the photo) and makes white objects pop with a glow. The UV LEDs are about 3x the cost of others, so 7 for $12 is a bargain. These UV LEDs are 3mm in size instead of 5mm like the others, but they are the brightest UVs I have found yet. They connect just like the other LEDs.

Hi I was planning on ordering some of your slow change leds but I needed to know what the voltage and forward current are so I can order the proper resistor. If you do not know but can tell me where you get the slow change leds from that works too because I can go and look up the specs.
The Slow color changing LEDs have a forward voltage of 3.5 to 3.8Vdc and a forward current rating of 20mA.
But if you are placing them into an LED hoop like the one I have on my site with the batteries I supply you should not have to use a resistor since the battery voltage is less than the LED voltage.
So if I order extra LED’s for my hula hoop can I just add extra, as many as I want? or do I need something else to in order to do that?
Hi Savannah, this response was originally posted on another page…http://prodmod.com/buy/standard-led-hoop-kit/
but this is probably a better place for it so I’ll repeat it…
To give you the best answer I just performed a quick test. I took a standard string of 21 LEDs from the kit and attached it to the standard non-rechargeable lithium battery. I then connected a second string of 21 LEDs to it. All 42 LEDs light up very well. I could tell that the first string got just a bit dimmer when I made the second connection. But generally still very bright. Its barely noticeable.
Then I repeated that test using the rechargeable battery. This time all the LEDs were very brightly lit and the first string didnt waver one bit. So I would anticipate you can put more than 42 LEDs on the rechargeable version. I dont know what the max would be.
So I would say you can definitely add 42 LEDs to your hoop with either battery, possibly more. The only major impact on performance is your battery life. I would estimate that 42 LEDs drain the battery twice as fast as 21 LEDs.
What voltage of resistors do you need, what determines what resistor you need? If I have the rechargeble battery and red LEd’s what type of resistor do I need?
To determine what resistor you need for RED LEDs you follow this formula:
(Battery voltage - LED Forward Voltage) / 0.020A = Resistor Value.
Most Red LEDs should have about 2.2V for the forward voltage. My rechargeable battery is about 3.2V. The LED should be limited to 20mA or 0.020A
So 3.2-1.1 = 1V
1V/0.020A = 50 ohms.
These are just estimates, the LED voltage is usually in a range so some are 2V others can be 2.5V etc. But if you use 47, 50, 52, or 55 ohms you should be ok.

Hi there! I am thinking of buying your LED hoop kit and am thinking about buying some additional LEDs to throw in it. I found this picture (
http://c3.ac-images.myspacecdn.com/images02/47/l_54eb158b5d95499e9566fc11bb5fc85e.jpg) and I really would like to get some of these lights but I don’t know what kind they are. I don’t think they’re normal LED lights, but I can’t figure it out. Thank you!
Megan, this looks like a hoop made by PSIhoops. I am not certain but I think the dashed light trails you see are created by the rapidly pulsed LEDs. I dont know of LEDs that would do this on their own, so I think you need a bit of electronics to get this effect. You can try the fast color changing LEDs I offer but I dont think it will look the same. If I create the required electronics I will post it on my site.
I bought an LED hoop with 24 fast changing LEDs last year. It looks OK, but compared to the more expensive PSI LED hoops, mine looks very dull and dark whereas the PSI ones seem to glow a beautifully bright white/blue/UV purple colour. This is very, very apparent even when the hoops are not being hooped with - when they are standing still. I don’t think this is to do with the speed of the flash because the bright lights don’t appear to flash. I am not so concerned about the trails effect, although I would think that the brighter light would make the trails more prominent - I just want it to be a lot brighter so that it stands out in a positive way like the others. At the moment, my hoop really stands out in a negative way when I perform with my group! I don’t want to have to buy another one because although mine wasn’t as expensive as the PSI hoops - it wasn’t that far off! What can I add to my existing hoop to make it brighter and better?!
where did you get this hoop from? i’m guessing its not with prodmod parts since we usually use 21 not 24. I’d have to know what type of LEDs are inside before i can say if the fast leds i sell here would be better. in general you can try giving it more power as long as you dont give it too much. But again, I’d have to know more about how the hoop was made before I can give you some constructive advice.
I got it from superhooper - perhaps it is 21 LEDs, but I thought that it was 24!
It is the SuperStar model if that helps? I am also finding that the piping is very wide and very stiff, so much so that it has grazed my back in a number of places! It also makes a very, very loud rattling/clattering sound!
I think that I may need to go back to the drawing board with my hoop, perhaps keeping the original LEDs and then adding new ones to improve the brightness and adding a rechargable battery. How about the purple LEDs that are mentioned on this site - will they give it that bright almost UV glow?
the ‘light’ purple leds on this site are no where close to the bright UV look. for a poppin UV look, you need to get…UV LEDs! u won’t be happy with light purple. You can order UV now and i’ll refund the light purple if u want
you’ll also see
instructions on my site foe silencing the hoop. takes time but its easy
How would it look if I put fast and slow changing lights with the UV lights? Or do I need to have more stable colors, what effect do the stable colors have? Thanks!
Hey! I’m looking for the LED’s that look white while they are still but when you hoop with them, they turn red, green, and blue… do you sell those? if not, where can i buy them and what exactly are they called?
I just submitted my order. I didn’t order any of the stable colored LEDs because I got anxious to order after my question, but if you think those are something I need please let me know. And I think what Lindsay is referring to above me are the super fast flicker LEDs? If you knew where to get those I would be forever grateful as well!
alicia, you ordered fast, slow, and UV. The UV are steady lights. Its all a matter of taste. I think it will look good.
Can you put both fast changing and slow changing LEDs on the same hoop?
Lindsay, I think you are talking about the dragonfly lights from PSI hoop? I don’t think there are individual LEDs that do that, I think it requires a small circuit.
katina, yes you can combine any LEDs that I show on this LED page.
I made my first prod mod hoop with the basic package-blue, green, and slow color changing, and it turned out really well. Now I want to try some different combos of LEDs. I’m looking for some of the super fast flicker LEDs like LED Heady Hoops uses. I want to mix those with some of your fast color changing LEDs. Do you know anything about those or where to find them? I’m also worried about using the wrong LEDs with the prodmod power source. Is there something I should be looking for? Or are most basic LEDs going to be ok?
I answered my own question and thought I’d share with you all. I talked to another hoop maker this weekend and did a little more research. It turns out the manufacturer of those flicker LEDs burned down, so you can’t get them anymore. psi hoops is the only maker that still has them in stock for their Dragonfly hoop.
I ordered a standard kit from you and some extra LEDs from superbrightleds.com but am not sure what specs I should look for and whether or not I got LEDs I can use. My question is what does mcd mean and is that going to effect whether or not I need resistors for my strings? I should have researched this more. Thanks.
mcd stands for millacandelas and its a measure of brightness. So that isnt an issue when connecting it to the ProdMod style wiring.
You do have to look for their voltage rating. In order to avoid using resistors the Voltage rating should be around 3-4 volts. These are typically white, green, blue, UV. basically the colors on this page.
But colors like red, orange, and yellow only require about 2-2.5V. if you use those colors you would need to use resistors.
My daughter bought one of your kits with UV LEDs. Do you have a data sheet for those or at least know the forward voltage and current specs for those so I can set this up properly. I plan on pulsing the LEDs to conserve battery life and need to know the typical as well a max ratings for the LEDs. Thanks.
The Vf is 3.2 to 3.6.
absolute max current is 30mA.
Pulsing the LEDs will help with battery life and also make really cool dotted trails.
The UV LEDs will light up other uv reactive colors too right. might be a dumb question, just wondering.
yes they should, depending on how close they are to the object
I ordered UV, fast, and slow flicker LEDs but I also ordered RGB LEDs from another site. It says that the forward voltage is RGB: 2.0, 3.2, 3.2 V. Is there anything different I would have to use like a resistor since the LED lights are mix of the 3 colors?
Hey, I am looking into quite possibly buying a large quantity of LED’s for hoops on this page… but I REALLY have my heart on having some pink in my hoop as well! I have seen pink ones in the store, but am not sure what type would be compatible with the LED’s I buy here!
Thanks,
Hoop Kyttn
I’m DEFINITELY making an LED hoop!! Took some footage of nighttime LED hooping at a festival recently in DC. Here’s the clip… Just fast-forward out to about 3:25 in the vid. The LED hooping lasts until about the 6:00 mark. >>

I’m a *total* newbie to LED wiring. Is this the best site for basic tutorials on getting familiar with LEDs & the wiring of them (including figuring out how much battery power / voltage is needed & also what resistors are and how to figure out which ones to buy)? If not, can anyone recommend a site or book?

Is there any problem with combining the slow and fast LEDs if using the rechargeable battery kit?
some have reported that the FAST change LEDs cause the other LEDs to flicker. But this is less noticeable when combined with the slow changing LEDs. Also out of all the power systems available on this site, the rechargeable battery system would be the best.
Got a question about a hoop I made…sold it to a lady that let the rechargeable battery totally drain out. She can get the LEDs to light only with the charger in the wall. Did she effectively kill the battery? I assume I can re-do the battery pack so my question is do you sell just the battery or will it come with another charger?
One more question about combining the slow and fast LEDs (with the use of the rechargeable battery pack) is there any issue with the “life-expectancy” of the battery or LEDs, knowing that flickering can occur?
The flickering shouldnt cause any damage to the battery, and definitely not to the LED since they are designed to flicker, they have their own chip built into each LED.
I will add the option to buy only the battery on this site shortly.
i would very much light to get some red, orange, and yellow lights…can i order them through you guys????
these colors require resistors to be placed in line with each of those LEDs. I dont offer them online but I do have a few. You would have to find your own resistors though and it requires soldering
I just want to say how incredibly HAPPY I am with the combo of the slow and fast LEDs. I have made some awesome hoops as of late–THANKS PRODMOD- these babies are GORGEOUS!!
first off - i used your kit and made a hoop that is rechargable. it came out very well. now I have others that want me to make them some hoops, but the cost of the rechargable puts the price at around $80. now from what i have found out the led lights are very well priced here and the wire you use is pretty generic and can’t cost much, but the battery and adapter is where the biggest cost is. is there some way of bringing that cost down? some of the folks that want these are kids, and the others don’t have much money. I am not going to make any money out of this, just doing it to help others.
Question about the white LEDs. I recently saw a hoop that was all super bright white LEDs. They were waaaay brighter than any other LEDs around. Are these white LEDs super bright like that, or are they basically the same as the other LEDs you have? I’m not sure if the lights I saw were something special or what.
They might be high powered LEDs, they are brighter, use more power and a little more expensive. Look for LEDs that draw at least 50mA or 100mA.
