Found some mega bright LEDs at frys

[billnchristy]

I bought some stuff for night golf at the rat shack last week and I was not thrilled with the light output.

We went to Frys tonight and found some LEDs with the warning "Do not look into LED, could cause permanent damage" :clap:

They are expensive, 5 are 19 dollars but they are MOFO bright...10 candela where most are fractions of a single candela.

The standard LEDs at radio shack were 26mcd and these are 10000mcd.

They do need a resistor or you will eat your battery and probably fry the LED too but a little 1/4w resistor adds nothing to weight...in fact it added the same 4g as not using one...the tape and battery is where the weight is.

I also scaled down to a 2016 battery because it is thinner, I have an LED and battery running right now so I can see how long they last so I will report back on that.

Here are the part numbers if you have a Fry's near you:

Linrose B4304H91 5 pack LED $18.99
QW162-25 620 ohm 25 pack 1/4w 1.99
2016 Battery 1.49

Again it is pricey but these LEDs are BRIGHT. I didn't like the 2-LED setup because they always seemed to have a sketchy connection.

can u post a pic of the set-up with the resistor? i have some radio shack LED's and they suck!

 

[Waddly Hobbins]

pics or it didn't happen.

Step-1 Gather your parts, Superbright LED, 1 620ohm resistor, some electrical tape, some clear duct tape, 1 2016 battery.

Step-2 Wrap the positive (longer) lead with one of the leads of the resistor, if you want you can solder it.

Step-3 Wrap that rascal in electrical tape to prevent shorting

continued next post...please wait to post until complete.

Step-4 Bend the resistor lead over on top of the taped one, you can bend it to make more contact with the battery.

Step-5 Place the battery between the positive lead and negative, tape that sucker to the center of the disc, make sure you got a good connection (light doesnt flicker)

Behold!

Hopefully that explains it well, I am used to posting electrical stuff on audio DIY forums so I am not used to step by step on stuff like that.

i bought 5mm leds i believe and some 3v cr2025 batteries. so far ive been using these for the past month or so. i love em! i dont know if these are the "ultra brights" but theyre pretty damn bright without a resistor.

specs:
intensity:7000mcd
viewing angle:30 degrees
FW current: 25ma
FW supply: 3.3v

 

[billnchristy]

Yeah 7000 is pretty bright.

LEDs are always supposed to have resistors but I think watch batteries have such low juice that they wont hurt them...it might prolong battery life but I don't know yet.

Mine has been burning for 4hrs straight now with no change in light.

There are:
10000mcd
20 degree
20 ma
2.2v

I took Electronics in high school, but I don't get the 20 degrees part. What does that mean?

 

[billnchristy]

This is how mine looks without a resistor, standing about 4' from the wall.

 

[billnchristy]

The degree is the angle of viewing, the light output drops off at higher angles but is still visable.

Ok, that makes sense. I did some work with LEDs back in the day, but I had never heard that term. I guess I had always thought of them as only seen from the top down.

I hear that's the way the Judges view things at the international Hooters Girl beauty pagaents.

 

[grass_stain]

i wish i would have seen this before i got my bolt on lite. it made my orc really darn understable, it turnd into a roller and i don't know how to throw rollers.

 

[33tango]

How would you say it affects your disc's flight path?

 

[billnchristy]

Haven't thrown in anger yet...I will let you know tuesday night.

 

[Midnightbiker]

Thank you for posting this. I haven't played a night round yet, but its on my list of things to do, and I like this idea for putting lights on the disc.

 

[billnchristy]

They have a glow round every Tuesday here and this will be the first time I partake.

I might take the discs out tomorrow with the batteries taped on just to see if it makes them flippy.

 

[booter]

none of my discs were flippy. but i center them. im guessin if you off set them somewhere it might effect the flight somewhat. ive been playing with mine for a month now atleast 2 night rounds a week and 1 on the weekend. no problems with them flipping and iv put them on orcs,wraiths,firebirds,stalkers,clear magic

 

[billnchristy]

The last two are going to be my set up, stalker and clear magic.
