Same here. I put 2700K philips all over my house 5 years ago and I haven't had any issues, but I have no idea of the quality of the power coming into my house from my provider.
(Anyone know how good Austin Energy's electricity on the west side is?)
Funny you mention animals. I often wonder if home environments have become screaming dens of high-frequency noise for dogs and cats. I know that flourescents tend to osciallate around 40kHz, and I definitely have an LED bulb that whines for some reason. Not to mention cheap laptop power supplies that also whine over time.
Are all these cheap SMPS driving our pets insane? (or just annoying them? or neither?)
I wonder if I could rent some super-high-quality mic from a local sound reinforcement studio and look at a 20-60kHz FFT ... or do fancy mics not really go beyond human hearing?
Having brought up an ERP solution with a team, this is no joke. A company with payroll, inventory, contracts, and logistics (to name a few), needs an ENORMOUS infrastructure of software to keep things running. There's a reason ERP is so expensive. In fact, I'm surprised it is only a US$41B industry. I would expect 10x that.
