LED Strip Waterproof 300 LED 2 5 meter 12 v strip

 

how would i wire these up to a 12v battery?

[doobin]

Anything 12v will wire up directly, or via whatever switch you chose. Unlike a normal bulb however need to have the polarity correct. You won't kill them if you get it wrong, but they just won't light up.

 

That LED strip is about 5x the price it should be though. Look on eBay.

this then?

 

but will it be that bright if 12 foot in the air

[doobin]

Mate, you started this thread two months ago! Sh!t or get off the pot ay?

 

Seriously, do as I did and buy a 1 or 2m strip for £4 posted. Try it out and imagine it scaled up. It's a lot brighter than you think. You could go the whole hog and try 5m in one corner. It's cheap as chips and can always be used elsewhere!!!

 

5m lights up my double cab Transit interior like day. That's an area approx 5 feet tall and it must be 6 feet square.

 

Have you decided what you will use to power the lights?

a 12v battery, proberly a high drain lesuire one

 

the problem i s i am so busy, have not got the time to sort it out, but now xmas is nearly hear i will have a couple of days to sort it out and order

[doobin]

How often will you use these lights and for what period of time?

[carpenter1]

once or twice a week

 

for 2 -3 hours max

[doobin]

OK, working on the assumption that all around the Transit cab provides good light, the caculations for your 30ft x 30ft barn are:

 

36m perimeter. £1/metre cost so peanuts in total.

 

4.8w/m draw. 172w total draw. That's 14.3 amps. A lot. An 80AH leisure battery would give you maybe three hours before needing to be recharged to avoid damage. There's a problem maybe?

 

You've got a big area to light.
