Sharp built a LED based lamp with a remote control named DL-L60AV in Japan. As the name implies, it’s supposed to be comparable bright to a 60W incandescent light bulb. That alone is quite impressive for a LED lamp.
I bought one of those for my wife. Since you cannot only control the brightness but you can also control the color temperature it did look really nice to have.
It did not take long that it occurred to me that the IR remote control ability means that by using an computer connected IR sender, any computer can control a 100V lamp. No need to twiddle with 100V electronics, no need to use any power electronics like triacs. Being hit by a charged elko once (that was back in Germany, so it was probably 325V) I have a lot of respect for 100V.
Kuroutoshikou has such an IR controller/sender named KURO-RS. I am tempted to buy one, but I unlikely will have time to play with this.
