Consume more power OFF than ON
Reviewed in the United States on December 4, 2023
I tested these with a multimeter and discovered that the electric current increased when the light turned off, rather than dropping to near 0, as I expected it would. Curious, I took one of the night lights apart and realized that in order to save some money on parts, they had simplified the design, consuming power in a dummy component when the light was supposed to be OFF rather than actually switching off the circuit. The ad suggests that the night light saves energy and only costs 20 cents to operate each year, but based on my measurements, it is more like several dollars per light. I am giving this product one star for a "bad" energy design, as it would have literally cost purchaser less to operate if the night light simply never turned off.
This product claims "Max 0.5W" but it's actual wattage is over 1W.
Actual wattage is 1.104W (9.2mA) when light is on and 1.128W (9.4mA) when light is off. This means electricity is re-routed to a circuit that wastes energy when it senses brightness. Apparently, this way costs less for the manufacturer. So, CAUTION: this night light does NOT save energy when the light is off.
If you leave one of these night lights plugged in all the time, annual electricity consumption will be about 9.78KWH (1.116W x 24h/day x 365days), not about 2.19KWH (0.5W x 12h/day x 365days).

Homeowners policies are regulated by state governments and have pretty standard clauses. There is no regulatory requirement that all electronic devices be ul certified. If a structure burned down as a result of a non ul device and the claim was denied. This would make the front page news. In my 30 years in the industry I have yet to come across a single event where a claim was denied due to a non ul device. I honestly would not worry.

Your picture is of a Vont light, not the Uigos light from the OP. There is a photo of a Uigos light in the reviews and it is labeled with the brand name.
