Can anyone tell me how I could test the difference between a 1 watt Luxeon LED and a 3 watt Luxeon led ? In as much as they both look the same, neither has any markings saying 1 or 3 so I'm assuming I know which one is which but would like to know for sure before attaching them to their drivers.. Would there be a difference in resistance or anything else one could measure with a MM ?
Thanks, Steve.
