Being as it has been resurrected by someone else. B&Q have 11W energy saving standard baynet fitting for 98p(phillips) at the moment

Slight thread hijack, I was using all LEDs in the kitchen, but finally decided I wanted to be able to see in the dark and put some mains voltage Halogens back in, these were previously blowing on me at an inexcusable rate This time round I put dimmer switches in, and touch would not have blown since. Which is more than I can for the LED lights which have proved totally unreliable

Well, I hear what everybody's saying, but in our search for more energy efficient lighting, we've spent the past few days wiring up LEDs to our 12v battery bank and I'd like to post a few pics of the kind of light they give.

We've got six lights plus a laptop running at the moment and that means we can move around the house without falling over dogs.

Here's one in the little room with the painting in it which uses less than one watt:

This one is a one watt bulb in the (unfinished

) bathroom:

Jema, have you any idea why your LEDs were unreliable? Here's hoping ours last for ages as they were very expensive.

So far, I'm pleased with the result.

No idea at all but the dead lights speak for themselves... actually since LEDs are reliable, and as all the LEDs are dead, it is obviously the transformer that blows.

That's a heck of an investment to lose just down to a dodgy tranny. Irene's on a 12v system though isn't she?

Yep Tahir,

I use 12v straight from the batteries when I can to reduce power loss.

When I need to change to AC I use a transformer. I've been using a cheapo £35 car transformer for the laptop for four years with no problems. (There you go it'll probably blow up today because I said that !!!

)

I've also got a 6OO watt tranformer for bigger things and it's been fine for six years (waits for explosion...)

On a 12V system you shouldn't have a reliability problem.

i have 1 ordinary 150 w .everything else is low energy exept a 12 v halogen which as it has its own transformer , it is probably not too good on energy but works well . my computer has an led from the usb but it is too dim to be of much use .if leds work as well as the snaps indicate im going to try some chunky ones .
