Emergency lighting

Was thinking about purchasing a self contained light for the house, in the event of a power failure, but notice almost all of the lights use ni-cad instead of lithium ion rechargeable batteries. Anyone know what the reasoning is behind this?
Thanks

 

Cost. NiCd are easy to charge while lithium batteries need a more complex and expensive charger. Also in an application where light weight and small size is not a concern there is less reason to go with lithium. Many emergency lights use lead based batteries because of their cost and simplicity in charging.

 

Personally I would invest in quality LED Flashlights with replaceable batteries like AA.
THIS is an excellent flashlight that can light my entire back yard.
HERE is a good one for general lighting.

 

We recently had an 8 hour power outage and out came my LED flashlights and one LED lantern and all worked fine.

My battery back up for my pc died many months ago and I just plugged all into surge protected power strips, but sure missed the pc during the outage. Dug up one of my failed UPS units and removed the battery. Charged up (after power came back on) my 12v deep cycle battery from my fishing motor and adapted some terminals so now I have a much battery battery for my pc back up.

Back on topic, that battery will ultimately serve as a 12v source for emergency lighting as well as my pc. A note of caution, seek advice before increasing the battery size if you go my route.

I did a little research on newer lanterns and just ordered THIS ONE.
It uses 3-D batteries but last 33 hours on high.

 

The nice thing about a automatic backup light is that it will automatically turn on and make it easy to go find your flashlight. But you'll have to figure out what area you want to illuminate unless you want to put a standby light in every room.

 

My lantern is similar and I have a convenient place to hang it to provide some ligth for the central part of the house.

When LED flashlights first came out I discovered I could hang one outside by the front door as a night light for the wife coming home late. Batteries seemed to last forever and not sure why, but it didn't collect a billion bugs in the summer.

I am a major addict of LED flashlights. I carry small ones powered by alkaline batteries when I travel but when night hunting use ones powered by 18650's. Even in red and green it's amazing how much light they can produce for hours.
