As per a previous blog post, we decided to use a C-Bus system for our lighting. We wanted to ensure we had selected an LED down light type that would be compatible with the leading edge dimmer technology used by the dimmer packs.
My father-in-law performed some testing with down lights we had looked at at a local Clipsal powerhouse, as well as others recommended to us. I won’t go into too much detail, however his findings can be found at http://www.cbusforums.com/forums/showthread.php?p=49956#post49956
To summarise, we have have decided to install Pierlite ECOLED1/3K 14W 3K as the compatibility with the dimmers was fantastic.
So that we could get an understanding of the light quality in a similar setting, we replaced five Osram Decostars IRC 35W installed in our current kitchen with the Pierlite ECOLED1/3K 14W 3K. This is a setting with 9.5 foot ceilings and a Clipsal universal dimmer. We did not have a means to measure the light output, however it was very obvious at 100%, the Pierlite’s were significantly brighter. So much so, that they are usually set to around 75%, which gives ample light for a kitchen. The Pierlite colour temperature was a small amount cooler and closer to the temperature we were hoping to achieve. i.e. did not want 4K for the house - the Pierlite’s seem to be a more modern/cooler warm light than the Osram.
The only negative observations that we made of the Pierlites: (1) when not 100% on the dimmer, there is a small delay until the LED controller fires and the lights pleasantly dim from 0-xy%. This delay depends on the dimmer position. On the C-Bus dimmer packs, this was perfectly acceptable - but still present (2) the colour of the Pierlite ‘white’ shroud did not match our roof colour. This is more of a reflection that we appear to have an off-white ceiling and our previous down lights were a brushed chrome and had not noticed.
