Bob:
I sent the reply directly to you but not the list. Maybe your spam
filter got it. Anyhow...
I bought a Brinks 7141W for $23.44 at Walmart. It does not come with
lamps. You will have to buy those extra.
I didn't find it on the Walmart web site but you can look at it and
download an installation manual from:
http://www.elightspot.com/180twinmotsecwez.aspx (or Google the model
number if you don't want to click on links in email)
I took a small transistor radio and held it up to the light and no noise
when using incandescent floods. Without cracking it open, it acts and
sounds like a relay closure. This unit is two days old so no good read
on whether it is durable or not.
