While waiting for a 3k system to be installed on my roof, I've bought
a small kit from www.solartechnology.co.uk consisting of a relativly
small 10W panel, 2 12v low energy bulbs - 9W and some cable. I also
bought a 12 v caravan battery ( the company who supplied the kit
advised a caravan battery to be the best) from halfords size 110ah I
think it is. Big thing.I am having problems with the bulbs blowing -
and at £13.99 a time they ain't cheap !
The first bulb I set up came on for a few mins, then died. I replaced
it with the other, and this has now been working for up to an hour at
a time, although there is still after 2 weeks a slight smell of
burning, and the bulb gets very hot - much hotter I think than the
240v energy saving bulbs I have around the house.I sent the failed
bulb back, and the company changed it no problem.I put this in, and it
too came on for a couple of mins, then died. I wondered if there could
be too much voltage coming from the battery.I have a multi meter, and
put it across my bulb sockets. 12 volts on both of them, so I guess
that rules out over powering ( I guess that wouldn't be possible
anyway on a car battery - or can it indeed chuck out more than 12
volts ?) I am not sure what else to do. Could it be another faulty
bulb, or what else should I try please ?
Thanks to all.
