that by using some 12 volt light bulbs to equalize them. The Leaf batteries sat unused for 14 months and maybe they are “waking” up? I don’t have a BMS or battery cell equalizers yet so have been checking
volts, for light bulbs and charging electronics (with "car chargers"). Since these are the only uses, our 100amp/hr set is totally sufficient for the 10-12 people at our homestead.

my experience with 12 volt leds.

They are cheap--2 watt light bulbs about 20-30 cents each. If you wire raw leds yourself you can get really long life, but it's a hell of a lot more convenient

Im talking about Xenon light bulbs ,the types used for cars.
They are really expensive but from China as a kit they are quite cheap.
A 30 watts xenon HID can give @3700 lumens wich its
for? Would they be good in light bulbs?
Thanks

Now (some weeks ago) that last one has gone, stopped working. I am sad, I can't get these light bulbs anymore. Only one very specialised lamp 'boutique' sells
incandescent light bulbs-

They used to make light bulb extenders back in the 1980's and it's hard to find these things anymore.

the heat pump I installed this past summer keeps 1/2 my house around 65 and the rest (bedrooms) around 62-63.  It draws as little as 250 watts (4 light bulbs) and even then doesn't run continuously

If you choose to heat your home with light bulbs in a completely different room
means I don't need as much energy to cool the house either.

If your primary source of heat was wood, then the amount of wood you save by the additional heat put off by incandescent light-bulbs

I would much rather talk about the dual-purpose-ability of each of the bulbs.

As far as color quality goes, there is an actual system for describing it for non-incandescent light bulbs. It's called "Color Rendering Index" or CRI. Incandescents by default have a CRI of 100

the solution may be on its way

Thank you for taking the time to enlighten me. 🙏🏻

In 2003-2004 I went from incandescent to CFL. As I could afford, I went to daylight spectrum (6500k) from warm white (2700k) and bought mercury free as they became available. The 'flicker' I have not seen for several years. Now LED are getting into the same price range as comparable to 2003-2004, and I can get the spectrum range I wish.

I have been slowly replacing some of my light bulbs, which are actually no longer incandescent anyway, but something else, to LEDs over the past two years.  Due to their high cost, I don't replace

LEDs can be 10 times more efficient than incandescent light bulbs, so you can get an equivalent of 1000W out of the 100W power source.
