Time-Nutters--
OK-- So flicker would be objectionable running off a
rectified 110VAC line.My thinking was to find
a way around needing a current limiter that would
waste energy as heat. Rectifying (and some filtering)
of the 110AC line seemed to be one approach.
I am thinking of building
Boy I have been staying clear of this discussion.
Pretty sure they make drop in led tubes now at $$$
Its funny we speak to a 100 watt lamp. But for a led that would be
something like 24 watts.
It makes no sense to speak in watts. Instead Lumens. I think we want the
luminisity of a 100 watt
saving energy. Last, I was hoping to do it for about the price of
replacement bulbs in my current lighting.

You really want to drive the LEDs with switcher designs typical in battery
chargers, basically hysteretic current output. Prior to LIon batteries (which
are voltage sensitive), the old nicad/NiMH chargers used the hysteretic scheme.
If you want a simpler switcher, you can take the garden
