Low-powered inline heater

[Alpaca]

Hi all,

I have a 34L tank and I have a 50w internal heater; I want to replace this with an external inline heater to remove clutter, but all of the ones I can find are much more powerful (like 200w) and I don't want to accidentally cook my tank, or have a bunch of additional sensors and emergency cutoffs. Are there
a) low power inline heaters
or
b) reasons not to worry so much about that particular failure mode?

I use High Power Habistat under tank heaters (11” x 11” - 25W) on my 60L and 37L. Run at 25°C and controlled by Elitech thermostats.
