What about fitting an approved CLIPSAL JB in place of the unprotected one..
Surely that would make it "Safe"

( Other than not knowing what the actual switcher/supply does )

I don't plan to use the existing power supply, as it clearly isn't approved for use in Australia, and quality is a big unknown. Also, it is mounted directly over the (quite large) heat sink, so is going to get hot in that position- which wouldn't help with longevity.

And when you think of the design, large boxes on top of the device, will buggar up normal convection...
Not all that bright when you think of it..

What is that light supposed to be... is it just a down light.. I'm looking for LED "pencil" spots...

Not a spot light- just a general room light, beam angle unknown, but the "lens" is translucent milky, so the light will be well spread. I'm sure you can find it based on the part number I gave earlier for the full specs, I wont promote it with a link.

We put Osram CFLs in our kitchen downlights in the mid 90's when they were new and cost about $20 each, from memory. These lights had fairly large bases which sealed the gap around the reflector when they were screwed in, which we thought would stop the flies getting in from the roof space and also enable the aluminium relector to act as a heat sink. I wrote the date on every one and most lasted only about 3 years, not as long as your average incandescent.

When I saw a photo of a test rig used to test these lights some years later, they were all mounted on a bench pointing at the ceiling - now why didn't I think of that :lol:

I have never had had any luck with CFL lasting very long.

The very early CFL's (1980's) lasted a long time but the modern ones are a bit "hit and miss".

I'd take a guess that "screw in" LED's as replacement for incandescent will end up the same way. The ones you can buy today, are probably the most durable that will ever be sold. Buy on in 10 years' time and it will cost $5 and have a design life of 4000 hours.

And how right you are... we converted our home's ceiling fittings to PLC cfl's in the 80s and many bulbs are still original..
Other plug in bulbs were replaced when the stupid government was giving bulbs away, and all have needed replacement..

We wait to see how these LED bulbs last... :roll:

$5 bulb that lasts 4000hrs or $20 bulb that lasts 20,000hrs when you think about it I don't mind the 4000hr job for $5. If you only get 4 years vs 20yrs but when you consider the price difference between the two if you purchase the $5 bulb the $15 cash can be in your bank for 4 year earning interest and you factor in in inflation over the 20 years $5 will be next to nothing by then.

There wouldn't be much in it between the two over the 20 years.
