   Saw an add in the Sancturary magazine for a 13W LED downlight hotbeam (Ceelux HB13). They are expensive, nearly $200 inclusive GST. But I am impresed with the product. I got the 60 degrees warm white version. It first nicely in the ceiling. It gives off a lot of light!. My impression is quite a bit more light than the 11W compact fluoro it replaced. And the light colour is great too! It brings out the color of the timbers in our house, almost similar to when the sun shines in the house. My wife wants me to buy more and replace all compact fluoro downlights with this one. When the dimmable version comes out I might do so. Just have to hope the current CFL's won't break yet. The LED lights are becoming mature and hopefully the prices will come down a bit. That will mean the end of the CFL.

   Cheers,
   Rob

   Interesting field report. The LED light's I've sampled so far have all had that slightly blue "alien operating table" feel to them. I've been waiting for the colour tone to improve before rolling them out in regularly used areas. I don't see why the cost won't come down like other LEDs have so I feel quite optimistic about this.

   It will be interesting to see how the colour stability goes. I've read that over the longer term the colour of the lights can change as the LED ages. Please be sure to post back here in 5 and 10 years time to report on that too!

   I could send you a picture. But that doesn't do justice to the color. I'll report back in 10 years about the colour stability. The price may have dropped too by then :-). That is why I bought one to evaluate it.
