So apparently the lights we have are the transformer types and I think they are called MR16 and I am trying to find replacement transformers, but I am not really having much luck. I believe they are 12v and slimline, anyone know what I need to look for? The electrician said he didn't know who had replacement any more.

I found this:

Any thought as to suitability?

Thanks switch lighting, do you think that option would provide better light than the halogens we have now? I note you are in Christchurch, do you have an Auckland showroom?

Anyone able to recommend a forum for discussing home lighting more generally? What I thought was a simple thing has me turned around confused and frustrated. 4 different lighting places have given me 4 differing opinions and worse, 2 people from the same place gave me opposing views.

My wife doesn't like hanging down single pendant lights as much and I like the hanging bar pendant style, but I am concerned about the amount of light output and whether I should go for LED, or Florescent, or just replace what we have with models pretty much identical but with transformers we can locate if we need to replace.

Here are some examples:

I don't really like this design personally, but it has a top and bottom light which is flexible. Something like this but a little more... nice looking would be good if it fits the bill.

The four spotlights put out quite a harsh light, that creates lots of shadows.

Like I said originally, I'd put in four LED downlights for general light, plus some kind of spots similar to what you already have for specific work areas. I can't help with lighting discussion forums sorry, I just do whatever I like after talking to an electrician.

Do you have an example of LED Downlights you would recommend?

So you are talking about 4 downloads and perhaps the 4 bar Varia's linked in my post above?

I got these, they'll be fitted in a couple of weeks when the bathroom's ready for them. The work area lights are really personal taste, but I would probably go for a large single light over lots of small ones if you want less shadows and more even lighting, as little spotlights make multiple shadows. With four downlights in that room it'd be pretty bright already.

I am extremely sceptical of the claimed light output. If you are interested in those bulb replacements, ask the seller whether thay have any testing information available to prove the claimed light output.

Well I asked, he said if we weren't happy with the bulb for any reason he would completely refund us. I am not sure how we could measure it ourselves, but for $40 it's not the end of the world.

You will find the Viribright 8W (not 11W) bulb sold at Bunnings for about $17 will produce more light, but it is not a reflector type so it depends on your fitting.

The cheap Chinese bulbs list the peak light intensity achievable from the LED element, not from how it is driven in the bulb. It is just as bad as the PMPO rating of sound systems, or dynamic contrast ratio of LCDs. I've bought a 9W LED bulb that looks the part but tested only about 4.5W. In the end the seller admitted the 9W spec is of the LED itself and not of the bulb. For the bulb the LED gets de-rated so that it lasts longer.

And with the cheap non approved imports you are just as likly to get something that has an atrotious power supply, or as was the case with one of the corn lamps I bought just decides to let out lots of smoke and have half the LEDs stop working.

Well it's ordered now, the place I bought it seem like they will look after it warranty wise, worst case I went through $40 to try something new, I've probably spent more on worse things.

I guess that just goes to prove things run on smoke, when the smoke gets out they stop working.

Very smelly smoke in the capacitor in the corn lamps. No idea if the plastic is flame retardent either and not really going to find out. Just going to deploy them in the outdoor post lights so if they do catch fire it doesnt matter.

I did the same with the corn lamp I got off Deal Extreme, put it in an enclosed glass fitting. Not taking the risk.

I haven't been keeping up with this thread recently, and can't really be bothered trawling through 27 pages (did do a quick search which netted nothing), so I apologise if this has already been mentioned.

Admittedly, it's a pretty damn expensive light bulb, but it looks like it could have some interesting applications.
