Strobe light lumens
Strobe light lumens
(OP)
I was recently ask to verify the light brightness from strobes mounted on high ceilings (approx. 16') by a triangle method. Does anyone know what that is and how I perform the test? I think the strobes are set at 95 from the manufacture but the building official doesn't think it will be bright enough.

Problem is how to measure. I have no idea.

Half full - Half empty? I don't mind. It's what in it that counts.

Unless we're talking about luminous energy, and then things take a different tack...

I'm in a hurry this morning, so I'll point you this way: Google "Luminous intensity of fire alarm strobe" and you'll get a wealth of info from the manufacturers and NFPA. The triangle method is simply a reference to the fact that the illuminance falls off with the square of the distance from the source to the illuminated plane at its far ends.
IESNA Lighting Handbook has examples.
Good on ya,
