The red Luxeon Star has a claimed flux = 44 lm @350 mA.
The Cree XR-C is 39.8 lm @ 350 mA.
Any brighter red LED @ 350 mA?

Luxeon Rebel Red is 40 lumens, Red-Orange is 50 lumens
Unfortunately the Star version is not available in red.
As a complete nube in the LED DIY world, I prefer an easy-to-solder star version.
DIY bike tail light.What do you actually want to do?
Stay tuned on that. Luxeon Star will have a line of blank Rebel MCPCBs in the next week or so. Figure maybe $1.69 each in small quantities. Grab up some stars, some loose rebels and solder paste, and learn how to reflow solder.
Hey Oznog: The 3 up Endor Star is something like 9 deg C/W/device. Do you suppose the boards from Asian Signals could be any worse? DANG those 100 boards for ~$35 looks tempting! Wonder if he'd fire me a couple samples of the 3 up square and 6 up round so I can do some testing.
The L2 flare lens might do a good job giving a very wide beam. But I fear its bizarre shape will make it difficult to integrate in a DIY tail light project.What I eventually ended up doing with that was loading it up with a TIR optic from DX that projected the light into a horizontal line pattern
OK, thanks for the advice.For taillights, use red-orange (aka "Sunset Orange").
What about driving it directly off two NiMH in series?a red power led @350mA can be a little too much for a bike tailight.
Three AA NiMH and a current limiting resistor will do a good job of keeping it somewhat regulated
