With that resistor (150 ohm; from the picture it looks to be Brown/Green/Brown/Gold, correct?), wire 4 of them in a series with 1 resistor. With that ring of lights, you should have 3 “strings” of LEDs and resistors. You can add as many of those strings as you would like as long as you stay with the 4 LEDs/Resistor.
ok cool
so what type of wire do i use?
solid or stranded?
what guage wire?
do i need to put heat shrink on/around them?
also, when it was one led and one resistor the LED was really bright
when i add 3 more LEDs will it be as bright?
Stranded wire, probably 18 or 20 gauge will work fine. Heatshrink everything.
As for brightness, with 1 LED and 1 resistor you were running about 3x the rated current through the LED. It will work, but it wont last long. So with 3 in series they will be dimmer, but they need to be.
One other spec that I didn’t see listed was the max forward current? I did my assumptions based on it being ~20mA.
I made a mistake above though; you want to run 3 LEDs/1resistor, not 4. (My apologies, I shouldn’t try and do math after drinking for a few hours)
As Mike said you have a 150 Ohm resistor.
EDIT: Ha, we got to stop doing this back to back. At least we have the same info.
thanks guys
looking at the pic i almost think the resistor is
brown
green
purple
gold
