Most tower lights look the same.

Same colors. Same mounting thread.
Some even share the same product photos.

Here's the difference nobody talks about:
Where is it installed?
If the answer is anywhere near gas, vapor, dust, or pressure —
then the light itself can become an ignition source.

That's not a worst-case scenario. That's physics.

The THT-EX L1920 is built for exactly that reality.
