LED Source (Photon Micro-Light bulb or better)?

Anyone know of a good source for the 6500k LED bulbs used in the Photon Micro-Lights? I contacted LRI directly to see if I could buy just some LEDs and asked if they manufactured their own. They replied that they don't but just customize the leads. So instead of cannibalizing my Micro-Light II, anyone know of a source for these bulbs or even better bulbs? I am making a custom keyfob and need one bulb to run off of 6V (2 x CR2025).

Also I need specs for a sealed momentary switch rather than relying on the leads to make contact by squeezing them. I am rusty on my electronics specs.
