I just moved into a 1965 house with BX wiring and a renovated main Panel in No. VA (you know, CIA, Pentagon, etc.). It's my first house that didn't have Romex cable.
I put in ALL new CFL's with 3500k and 4100k temperatures because I hate soft white.
In 2 months, 8 CFL's (new out of the box) have failed. They were 3 different manuf labels - Home Depot house brand, FEIT and a 3rd brand named Maxim. The Maxims are PAR40 CFL cost $9 each so this is getting expensive. I had used PAR40's with a dimable switch (but went to non-dimable after 4 failed in 3 weeks. I always kept the power at max but then got the conventional switches.
The fact that that CFL's from 3 manuf are failing is very odd.
My experience with CFL's is 2-3 years life (never the 8 years 10,000 hours promised), but I'm talking service hours in the several hundreds here.
Does anyone have ideas on what's going on.
