I believe you should look the TLE-10 from a different perspective. Before the TLE-10 came out, I used Tektite LT-1 in the Minimag AAA.
Then, Tektite renamed the LT series and started using Nichia CS LEDs in them. The TLE-10 uses a Nichia Rigel diode.
The LT from Tektite and the TLE-10 from Terralux both draws 160 mA at 3 Volt. The Terralux has moree than double of the flux, I can measure approx 12 lumens at front end.
So, the Nichia Rigel has double efficiency of a overdriven Nichia CS. Much more light for the same power.
The big drawbak of the Rigel is the fact that it wasn't designed to be focused. Like the first generation of Luxeons, the phosphor cap is not conformed to the InGaN blue die, so the tint of the emitted light depends from the angle of observation. When you focus the Rigel, you get a blue hotspot and a green-yellow corona.
While this is OK for general illumination purpose, it is a big-no-no for medical use, where tint uniformity is an essential prerequisite. This is also true for other color-sensitive applications.
This said, I enjoy my TLE10 modules.
