cheap led lighting $2.50

[rusty ironMan]

I picked up some of these lights in Lakeville and some rubber tubing to mount them... I'm still thinking that I'm going to wrap it in electrical tape... If you plan on picking some up, make sure you get the white ones (it says in the bottom right corner if they are colored) of course I picked up one white and one colored...

$2.50 per box of lights

$3.29 for 10' of the rubber tubing

I just picked up two packs at the Target in Lino Lakes. They had a bunch more left still. I am pretty impressed about how much light they give off. I think i might pick up some of the 3M velcro stuff to mount it in the fish house and maybe another set of LEDs.

I picked up 5 sets at the store in my town. They had to have another 40-50 sets there. Boon to us,? why they're selling out. BTW, They ARE BRIGHT!! Thanks for the heads up, mustang69! Phred52

Ferny's WHITE LED facts:

Most need between 4V to 4.5V to emit light.

White LED's are very sensitive to over voltage.

NIMH rechargeable AA batteries only put out 1.2V each.

Alkaline AA batteries put out 1.5V each.

You can wire the strings up in series to work on 12V if they have a 4 cell battery pack.

Series = + - to + - to + -.

Series = 1.5 +1.5 + 1.5 = 9V

3 AA cells in series = 9V

Parallel = + to + to + also - to - to -

Parallel = 3 AA cells = 1.5V

If you want to run 1 led @ 0.02 amps with a Vexi battery you need about a 400 ohm resistor in series. 12V battery minus 4V led drop = 8V divided by 0.020 amps = 400 ohms.

If you want to run two sets of 3 battery (4.5V) LED lights.

You need to wire them in series + - to + - and to drop the extra 3V you need to do 12V - 9V (2 series LED sets)= 3V divided by 0.020 amps = 150 ohm resistor.

If you want to run two 4 battery LED light sets 4 X 1.5 = 6V times 2 sets = 12V with no dropping resistor.

The important thing to remember is that your auto probably charges at 13.8V to 15V! That means if you charge your battery with your vehicle and have your lights on you can double the current through the LED string and damage them.

Most of the time when you are exceeding the LED's ratings the color changes and usually it's too late when you see that!

Want more info Google Ohm's law for some formula's or resistor calculators on-line and knock yourself out! hsolist has tons of loose LEDS for your needs and they're cheap.

Good Luck,
