The 90 W-equivalent flood I got is rated at 1500 lumens and consumes 18W. If all of that 18 W is dissipated as heat (unlike an incandescent, it isn't), the can enclosure is being operated at 30% of i

Good news: I'm clean on the new modem and it's clean with me. I wrapped about 20 turns of the DC power line around my toroid core (I think it's type 43 because that's what I had on hand) and there is

I respectfully disagree. GFI isn't intended to prevent a shock: it's intended to prevent death by electrocution. I suspect they do that admirably even with 600 uH total inductance split over two legs

Simply take note of the noise level with the lights off, then turn them on. If you can't detect a change, then how ever much noise they might make isn't detectable at your station. Kim N5OP "People t
