[SML] Dummy load resistor?

[Dan Sheehan]

problem with heaters etc that aren't tungsten lamps...

if they have the resistance of a cool lamp,
as is needed  to stabilize the dimmer/LED combo at low level setting,

they will have approx that same low R when the level goes to @FULL
thus draw much more power...
unlike a tungsten lamp filament which has almost 10X the cold R when @FULL.

So looking at a 40W lamp example
(which I've sometimes  found to be about the smallest-W
lamp that will work for stability)
that  lamp, heated @FULL, has about 360 ohms to draw 1/3 A,
thus about 40 ohms cold.

Replace that lamp with a 40 ohm Resistor [heater] for same stabilizing
effect,
it's still near 40 ohm @FULL, 120V on 40 ohm is 3A, that's 360 W.

You would have to figure out how to handle 360 W of heat.

If it's not going to be @FULL for a longtime,
bury the 40W ballast lamp in a tin can or something.
You can provide air flow and still block the light path,
so it will be hot, but dark.

The apparent complexity of the math
 is inversely proportional
to the level of beer remaining in the bottle.

Currently enjoying a KONA (HI) product.
