Default Why aren't many / most LED light bulbs dimmable?

I don't think I've seen one yet that is ok to use with a dimmer switch.

I can understand why CFL's can't be put on a dimmer - but why not LED
bulbs?

They're crazy-priced as is. *Not being able to dim them makes them even
less desirable as a replacement for incandescent bulbs.


THEY ARE LAZY... THE DESIGNERS USE THE WRONG SCR FOR WAVEFORM
RECTIFICATION, AT HIGH FREQUENCY IN WHICH CFL's WORK TRIMMIMG THE
INPUT WAVE IN BOTH VOLTAGE AND CURRENT RESULTS IN FLICKERING.
THE RIGHT ELECTRONIC DESIGN COMPONETS WOULD CORRECT AND PREVENT
THATNFLAW.
AS FOR THE LED's , THE SAME APPLIES IT IS NOT TOO DIFICULT TO REDUCE
THE AC INPUT WITHOUT CHANGING THE FREQUENCY....THIS CAN BE
ACCOMPLOSHED USING A CLAMPER IN THE IC INSTEAD OF A CLIPPER CIRCUIT.

EASY AS PUMKIN HEAD I MEAN, PIE.
