true
handheld (or fan cooled) the output goes up about 100 lumens
freestanding uncooled the output is lower than handheld.
The most likely damage would be from free standing, uncooled, starting from Turbo, which is how some people test runtime…
I absolutely do not do Turbo tests, not handheld, and definitely not freestanding uncooled.
I also dont use H10 batteries, I limit myself to 3A discharge rate cells such as the stock Wurkkos cell, the Vapcel L10, and the Vapcel F120 (which has the highest capacity).
All the smoking and damaged TS10 reports were from people testing Turbo w an H10, and uncooled. There were even people that thought it was a thing to do, to hold the light by the tip of the tail, avoiding contact with the too hot head…
Honestly, Turbo at 40 Lumens per gram is just way out of reasonable range, imnsho…
To quantify how Turbo is your Turbo, I think the Lumens per gram metric may be a good way to put things in perspective.
Rule of thumb, 5 lumens per gram is Sustainable, above that, not so much…
Turbo marketting reached its peak with the TS10 and the FWAA. Both have really steep discharge curves in the 40 lumen per gram range… Totally unsustainable.
The TS10 also taught us that Bright Aux have a practical limit… with the TS10 draining a battery in 4 days on Bright Aux…
Im still influenced by my HDS experience… they are limited to 200 Lumens max output… That design runs at a max of just 2 Lumens per gram. It Never gets hot.
