I saw reasonably good deals on LED light fixtures like motion sensing ones
on Amazon. Since these need AA or AAA batteries, I was wondering whether
anyone has experience with these gadgets. Can they indeed use NiMH
rechargeables with reasonable effectiveness?
We have a light like that. It is a faint "flame-like" light. It worked
for a season, then the NiCads went. The thing is in a somewhat shady plae,
and the solar cell weathered rapidly. It's just decorative now.
I hope you will have better luck!

I bicycle to the train. Each evening going home (Sept thru April), I need
the head and tail lights on my headband, so the cars don't get too close.
Headlight uses 3 AAA's and lasts about 2 weeks or more per charge (ride is
only 5 min). Tail light is flashing, 2 AAAs, and lasts months. I have
been using the same sets for over 2 years.
So it may depend on the batteries.
I was asking about the lights one sticks on a wall or doorframe, but I
think the best answer is trying. I just don't like buying boxes and boxes
of disposable batteries, eve if they would last 3-5 times as long as
rechargeables last on a single charge.
Old style NiMH batteries are horrible batteries to be used in standby
applications. Their self discharge rate is so great, they will never
be charged when you need them.
However, newer NiMH cells using hybrid technology are every bit as
good as regular non-rechargable alkaline cells. Eneloop by Sanyo is
one such. Rayovac makes one called, appropriately enough, Rayovac
Hybrid. There are others. They will work quite well.
I put some of those LED lights in the camper and my wife loved them
but changing battereies was a bit of a pain. It seemed we were
replacing the batteries everytime we took a trip so I wired them in to
the 12V system. You cannot just hook them to the 12V system. The
lights I used used three batteries so I use a regulator to take 12V
down to 4.5. I have LED under counter lighting in my home also and the
plan is to put a battery backup on these too.

My wife picked them up at Lowes or Home Depot. She said they were
almost giving them away. I think they were about $12 for a set of 4
fixtures and the power supply. I have since looked for more but havent
seen them. They arent bad lights but they arent great either. They
arent sufficent as task lighting withoutthe main lights on but they do
brighten up the dark corners and shadowws that the main lights leave.
