That LED light is what I need to look into after our Winter power outage problems.
Is it hard to install
@Happy Joe ?
Since, I believe, its powered by 120 volts House wiring) I expect that most folks will need an electrician. For my self; I intend to modify it to install below a ceiling fans; which will likely involve some fabrication hassles..
I would not recommend it for power outages unless the user also has a 120 volt home generator/emergency power system.
For short power outages, up to a couple of days, I use my 12 volt (35 amp hour) scooter battery, that I keep for camping, powering a very small (12 to 120 volt) inverter along with existing table lamps that have 120 volt LED bulbs installed. Lights go out; remove the battery from the battery maintainer/charger, carry it to the table lamp , unplug the lamp from the wall and plug it into the inverter connect the inverter to the battery, switch it and the light on, and pick up a good book or the e-book reader.
The battery supplies a limited amount of electricity, the inverter converts it to 120 volts, allowing me to easily run a very few , relatively dim (400 -450 lumen/50-60 watt equivalent) LED lights for up to a couple of days.
I also use oil lamps for emergency lighting.
For emergency heat I use thermostat controlled semi portable propane heaters.
Enjoy!
