What i hope to show you is how to make quick LED lighting that is on a TINY buget.
What you need :
Resistors (510Ohms for 12V)
Cutters and other basics
Hammer and a nail!
(NOTES FOR n00bs)
LEDs need about 30 milli amps (0.03 Amps) or they burn out
To work out your resiance use:
Voltage (V) = 12
Amperage (I) = 0.03 (30*10-3)
Resitance (R) = ?
i used 510 so my LEDs arent running at the brightest they could be
Step 1: Costs
Cable : 8.51GBP high grade white cable per 50m ($13.99)
LEDs: 6.18GBP (Cheaper by the 1000) (the LEDs i used are 13,000 and 6,000 mcd with a angel of 25 degrees)
Resistors x100: for 0.99GBP
Staples: Well cheap...
Which works out at:
0.89 per metre!
Spacing of 1 LED per 10cm is enough (get the spacing right or it looks strange)
which isnt bad for really nice lightening that on average the leds will last 11+ Years!
I used a power adapter i had lying about but anything that is 12V and lying about will do fine :-)
Just as a general rule you need 30mA per LED. (this isnt strictly true, but it will keep you within tolerences)
so if you had 20 leds you need (30*10-3)*20=600mA or 0.6 A
Step 2: Cable up the room
Seen in the picture is what your cableing should look like all the way around the room (or where ever you want the LEDs)
