I want to change the luxeon K2 emitter in my light that is soldered directly to the driver board. It is being driven at 1000 mA and 2x 123s. What led would be dimensionally the same but more efficient?
I tried looking around the forum and Google, but couldn't find the answer.
The ssc P4 led is very similar in size and other critical dimensions. Most other power led's are going to surface mount technology so I think it'll be your best bet. K2's are about only 40 lm/w whereas the P4 is around 90 for the U-bin. Plus the P4 is dirt cheap, $3.97 on DX.
