Eufy offers a 4-pack of its Lumi Plug-in Night Lights via Amazon, for $11.99 when you clip the coupon on the page. This is 20 percent off the regular rate and is among the best prices we’ve seen, apart from a drop to approximately $11 we saw a few months ago. The ambient light monitoring will only be activated when it gets dark at home. Eufy claims they will only “cost around 30 cents a year,” as they only turn on during the night. If your home is pretty dim at night, simply add 1 or 2 of these lights and never stumble again. 4.6/5 stars rated.
