Try:
optekinc.com

There is another one that makes ultra-bright hermetic leds in metal
cases, but it may take me a while to find it.

TO-66 cased leds,

Roithner is a reseller, but I cannot for the life of me remember the
manufacturer. They do a lot of mil-spec work and often advertise in
Photonics-Spectra and Laser Focus World. They also make stuff smaller
then the TO-66.

Have you looked at some power LEDs designed for 0,7-1,5 A operation,
which are claimed to work at very high temperatures and running such
devices at much lower currents for indicator purposes ?

For instance the Luxeon K2 the claimed storage temperatures range of
-40 to +185 C.

The data sheet also claim:

>Autoclave compliant� JESD22 A-102

>Autoclave Conditions 121�C at 2 ATM, 100% RH for 72 hours max

Is this sufficient for your application ?

Now that is nice, a 3055 with build in headlights :-)
