This TIR lens offers flexibility. It can create many beam patterns, from wide angles to spotlights. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch.


Flux3000 lm
Intensity2500 cd
Throw100 m
CD/LM factor0.83

The 3000 lm output of PT40 SST20 provides great flexibility. You can adjust the brightness to fit different needs. The PT40 SST20 flashlight has 2500 cd. It provides a much brighter and more intense beam. The throw distance is the farthest distance the flashlight can light an object. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.

If accurate color is a priority for you, choose a flashlight with a CRI of 90 or above. Flashlights with a CRI of 95 or higher are usually seen as top-tier. They may come with premium features and parts.
