(plasterboard) cieling for AU$5.20. Very cheap then if the lampo blows it
costs about AU2.65 for a new one!! Why modify when I can get the 20
watters cheap and save the hassle (and the grumpy looks from the funds
manager when I show her the modified garden lamp!!)
>Or use them all the time and ac only when needed.Once I've saved up for the solar panels I'll look into it and make a
which way to go. The walls are already up plastered and painted but there
is plenty of room to put more cable in from the cieling space later anyway.
- I will get the data to you but it will be at the end of August due to vacations, etc.
