To be honest my wife has had far too much to drink at lunch and since she is now asleep I was thinking…

If i was to buy a 12v 7aH battery like this

and 6 MR11 12v led bulbs like this

http://www.ultraleds.co.uk/15-led-mr11-180-lumen-cool-white-ac-dc-2-5w-30w.html

and mount them in 6 respective mr11 down lights in the roof of my garage above the workbench like this

My calcs are as follows.

Battery 12v 7aH

Bulb – 2.16w / 12v = 0.18A per bulb x 6 = 1.08A draw from the bulbs if wired in parallel

1.08A drain on a 7aH battery gives me a 6.48h run time.

each bulb gives me 180 lumens so by my calcs that is a gnats cock over 1000 lumens which should be enough for winter fettling

Battery can be taken back into the house for recharging and a solar panel option could be added later

My question is:

What have I missed?

I think you forgot the home brewing element? Perhaps a nice stout?

It is safe to say all wiring will be done whilst under the influence of a decent ale! Bear jacket and all that! 😀

WCA to the forum please, WCA to the forum please

not looked at all the links but sounds fine to me. Don’t let the battery get/stay too low and definitely do the solar charge thing with a charge regulator/cut off thingy.

Cheers. Think i am going to have a punt at this!
