LED shop lighting at Costco
bkenobi:
My PUD has instant rebates on LED lighting (as discussed in past threads). They currently have shop lights at $22 OTD. These are the non replacable double tube style lamps rated at 42W and produce 4000 lumen. Thats about half the energy of a standard shop light and similar light (2400 lumenx2=4800lumen).
I'm only looking because my current bulb supply will eventually run out and ballast and tombstones do have to be maintained. A pair of bulbs or a ballast are about the same price, so this seems like a good option as they fail.
That said, I am seeing a hit on signal strength with a single fixture in my testing. My XTBM shows 8.24 without the light but 6.50 when turned on. If I lose 2v with a single fixture, am I screwed if I install a dozen (for instance)?
brobin:
I'd suggest adding a filter or hash choke to the lighting circuit. If you have a filter now you can test to see if it helps.
bkenobi:
I can test with a SmartHome filter. Assuming it works, I won't want to use it though. What kind of a filter/choke would fit inside a lamp?
Brian H:
Do you know the input current rating of the fixture?
So a choke or wired in filter can safely handle the input current.

You may want to read this file from Simply Automated. For some information.

The ZNF10A-W is a wired in capacitor and coil. Supposed to work with all automation protocols. As it suppresses anything above 4KHz.
There is a thread on Cocoontech on what parts are in the kit as it is not too cheep.
