Quick question on colour temperature ...

... normally not something that would interest me, but I'm building some custom lighting units for the boat

What is 6000k? Will that be a warm white or cool white?

CCT 6000k is generally regarded as a cool(ish) white light. But CRI is usually of more importance than CCT, especially if seeing colours correctly is important (the higher the number CRI the better). If you want to investigate further there is lots of info over at cpf (candlepower forums).

Cheers mate

That should be enough info for me thanks Greg

I have two 5m reels of SMD ribbon, one of which is known to be warm white and the other specifying 6000k. If the 6000k is a cooler/sharper light, they'll be my primaries with the warm ones used for softening and for separate mood lighting options. I just wanted to make sure it would be reasonably balanced before I started

Usually for torches people like 4500K as it is believed to give the most actually useable light, as far as I remember from CPF and BLF.

Of course it all depends whether you want just light or to create a "mood" too.

Thanks for that D

I went out into the street the other night and played with a couple off my car battery

The 6000k are very similar to the ones shown second from the top on the chart, and throw out a good amount of light for "doing stuff", and the "warm" ones seem somewhere between the 3500k and 4000k, perfect for a softer light effect

I'm setting up varying light levels in a couple of areas with a 4 gang switch operating two ceiling lights with 4 independantly switched LED clusters in each light and the light levels vary by how many switches you turn on. I'm also having low level lighting in warm white for less intrusive lighting. The ceiling lights themselves are deep woden picture frames mounted on mirror plates. An unusual look, but one that should work well with the quirky layout
