All LEDs are dimmable but the old standard simple phase shift type dimmers are not so suitable for them (messes up the internal inverter power supplies).

One of the most significant costs in LED lighting, and it would apply to graphene and CFL as well, is the number of independent power supplies and inverters that are duplicated and integrated into them. These are expensive, and involve a great deal of redundant power transistors, capacitors, resistors, diodes and inductors to be distributed in the runs of these lights, each independently converting AC to DC.
The best solution, is to have your home wired for low voltage DC. This is one main switching power supply that will supply the 5-12 volts with on-demand amperage, located next to the mains AC distribution in your house. This will be the future norm in newly built housing, but you can have it done, or do it yourself if you understand how to snake the wiring and put in receptacles in key places in the house. This is also a way to save even more electricity, as this method of providing power is much more efficient. It also completely eliminates the need for most wall-wart devices that are constantly on, and become an unsightly and unmanageable tangle of wires at your AC receptacles.

This is my personal dream having gobs of audio gear.
The problem is that most units have integrated AC to DC converters, not impossible but a huge task.
Also, I have never owned property and likely never will so, it seems I will be longing for central DC forever.

I just clip them out and put DC pigtail connectors on them. Chain them together in parallel, then out to a DC receptacle that can handle the combined wattage.
(switches and dimmer in between of course. DC Dimmers are very smooth, no messy AC artifacts.)

" Before the incandescent bulbs go out for good, it’s worth shining a light on its cause: The ban was pushed by light bulb makers eager to up-sell customers on longer-lasting and much more expensive halogen, compact fluourescent, and LED lighting. When customers balked at paying more for home lighting, General Electric, Sylvania, and Philips did what corporate behemoths always do: They turned to the government for regulation that rigs the market in their favor.
