GURPS Lensman was the GURPS version of Edward Elmer "Doc" Smith's epic Lensman series mainly pulling from Triplanetary (1934/1948) to Children of the Lens (1948/1954).
GURPS Lensman was written before the alternate TLs of Steampunk were created and as a result uses its own Tech level system (called Tech Stages)
"An extremely rough correlation can be forced between Tech Stages and Level. Tech Stage 0 is equivalent to Tech Level 6, and TS 1 is approximately TL7. Stages 2 and 3 could be compared to TL8, though the GURPS Tech Level does not account for allotropic iron as a power source. Then Stage 4 is slightly analogous to TL 9 and 5 to 10. but then all of Tech Stages 6 though 8 must be lumped into TL 11. Finally stages 9-10 could be called TL12." (pg 65)
However, GURPS Lensman treated TS as if it was TL with regards to penalties. For example, TS 2 and 3 are effectively the same TL (6+2) but are -5 going from TS 2 to 3 and -1 going from TS 3 to 2.
This combined with the heavy amount of superscience in the setting, the use of the pre Steampunk GURPS 3e TL system, and that these TS are very loose makes trying to relate GURPS 4e TL with Lensman TS problematic at best.
For example, in medicine they jumped from unable to cure infantile paralysis (TL6) to full regeneration (TL12) in one step.
It is warned, "GMs who allow equipment into a Lensman campaign solely on the basis of technological rating will encounter difficulties." (GURPS Lensman pg 65)
It certainly doesn't help that information on Biotechnology/Medicine is borderline nonexistent in the GURPS book.
