Is it possible to update the E1E Surefire to LED, i.e add a LED drop in such as a Cree LED ?
Come over to the light side and enjoy the colour-rendering goodness of glowing tungsten...
You'll need one of these
...and one of these
... and a 3.7v Li-ion RCR123a charger.
This will give you just under 60 Surefire lumens in a compact, rechargeable package. Is that any good to you?
What is the runtime using that setup?
You can replace the existing E1E head with either of these:

For the E2 replacement LED head, you should drive it with a 3.7V Li-ion RCR123A cell for best results.
CPF has several reviews of these two products. For example:
