Reply #84: Another problem with LPS lighting...

[jmowreader]

It has a unique turn-on electrical signature, and the cops know what it is. In some places, the cops have power line analyzers; if they think you're growing weed in there, they can hook a power line analyzer to your service entrance cable, wait a day or so for the LPS to switch on, and use the presence of that signature on your power line to justify a search warrant.

So...if you're growing weed under sodium lighting in your house, plug your lights into an UPS. An uninterruptible power supply, which has a battery charger, a battery bank and an inverter to power the load, will absorb the crap your lights put out and keep you safe.
