I wonder if you can advise
I wonder if you can advise me.
I have just bought a commercial light system which is running 3x luxeon III led's overdriven to 'nearly' 4W all running from a 16.8v Li-Ion pack. I have no other specifications sadly.
I was thinking of substituting in either a Luxeon K2 or Cree XR-E for one of my current led's to get some more light. Obviously the luxeon K2 star would be an obvious choice due to its similar specifications and same mounting plate. I'm not sure i would appreciate the difference though and am tempted by the higher output of the Cree XR-E. It should be able to handle the 4W ok but I am unsure what voltage/current is being delivered to the system.
I have no experience with constant current power supplies and am a little worried that changing a led will end up blowing it and (more importantly) the other two luxeon III's or even the power circuits. I presume the resistance of the led is the key here?
What would be your view on my little project? Worth a shot or just plain silly? :)
Cant wait to see how your system turns out.
Cheers
