HYBRID EXIT SIGN DURABILITY – THE EMPIRICAL EVIDENCE

Ecoglo’s Hybrid Self-charging LED Exit Sign, with its superior backup technology and innovative electronics, is designed to last.
The theoretical calculations of FIT’s (Failures In Time per 1,000,000,000 hours) show that the Ecoglo exit sign is around 300 FIT with “best in class” battery backup competitors ranging from 2,000 FIT to 3,200 FIT.
That’s the theory but what about the practical?
We have had 74 units running in a test facility, at rated voltage with normal supply spikes and no temperature control, since December 2018. That’s equivalent run time of over 2 million hours or 241 years!
How many failures have we had? ZERO!
The stats gurus tell me that if we had 1 unit fail tomorrow then the FIT calculation would be 473 which is starting to get very close to that theoretical 300.
That’s why facility managers love Ecoglo’s hybrid!
