I have immense respect for Color Kinetics and the way they are bringing LED technology to the world. I would certainly have no hesitation in describing them as leaders in the field. However, I would also say that in many ways I regard Chromacore® as a new name for an old trick. Varying the mark/space ratio to control brightness is something that thyristor dimmers have been doing since the 1960s and although the application of this idea to LEDs relies on more on persistance of vision than thermal inertia to create the dimming effect, it cannot be regarded as a totally original idea. Again, no disrespect to CK intended, they are working very hard and deserve to do well.
I know that 35W is too low for industrial lighting. The Droplet is a very small unit, designed more for indoor / display use. It is in many ways a test bed for the ideas and larger / other instruments are, I'm told, in the pipeline.
Other contenders in the field are the
Pulsar Chromarange. Their Chromabank battens are starting to appear everywhere over here. Also striding along are James Thomas Engineering (previously best known for their aluminium trussing) with the
Pixelrange line of fixtures. Another UK company whos name has been bandied about recently is
NJO Technology, although their site has been "under construction" for some months and I have no real info on them. Back in Holland again there's
Lagotronics and their Lagoled system, although the site is being rebuilt at the moment.
Hope this all serves to add to the knowledge base.
