Picked up the 9w ones last time. No way they are equal to 60w bulbs, more like 40’s. A couple come on when the switch is turned off no matter what, other bulbs work just fine in the same lamps. Every time I lose power they do NOT come on (been having bad storms around me). I must remove them from the outlet and use the little “socket” adapter to get them to turn on.
Overall, great idea, horrible execution. Would never recommend these.
According to my electrician friend who owns these, no. They function like normal light bulbs. The circuitry recognized the difference between an open circuit (switch off) and a closed circuit with more power. He has the 60 watt equivalents and I have used them when we were on a camping trip. I’ve been waiting 2 months for these to show up again.
The crucial thing to know is that to work like regular light bulb with battery backup that turns on/off with the lamp or wall switch with/without power, the lamp must have a single LyfeLight bulb and no other bulbs, downstream from the switch.
The electronics in the bulb has to use/charge/sense the 120v AC from mains to turn on from electricity. And it has to be able to sense the impedence differential from a circuit lacking power and the switch is turned on, extending the length of the hot wire.
Being this dim, as others have commented, here in america we are more likely to use multiple low wattage or single higher wattage bulbs in our lamps to provide the lumens we are used to. That makes them not as functional in our homes.
bought these last time offered, but was very disappointed that the small device to plug in did not work. there were 2 in my box & only 1 worked which I had gifted to a sibling.
