re: Future of SSL LED lighting is not dim, but it’s flickering

In the US, incandescent bulbs are being phased out by law by wattage (I'd call that "banned") in the US. 100W was phased out in CA last year, and is phasing out in the rest of the US this year per congressional mandate. Next year comes 75W, and so on (all part of the same bill, already passed). Not sure what sort of linguistic contortion LEDAgree is attempting...technically the bulb itself is not banned, just the sale of it. Stores can still sell their stock, so it will take several months to see the effect. If you want to make your own bulbs, go ahead, I think that is legal. You just can't sell them or buy them. Ok, you're right, not banned. The wording in the legislation is a little obscure for most people - it sets lumens/watt minimums rather than "banning" incandescent, but the effect is the same. You won't be able to buy 100W, 75W, etc. incandenscent bulbs. And yes, the lower wattages are not banned for now. How many 40W bulbs do you have in your household lighting? You've got a few years left before those no longer meet the lumens/watt requirements in the passed legislation. Enjoy the dim light, at least it doesn't flicker. I personally like that I can screw in a bulb, not have any flicker, and dim it with a simple, inexpensive, old-fashioned, voltage-varying slider switch. I am baffled at why Michelle Bachman is pillorized for supporting the freedom to buy a darn light bulb. Seems even more bizarre to me that congress acted to ban light bulbs.

LEDAgree, my computer is on, as is the case for anyone who is reading this (not a very perceptive suggestion, by the way!). What global world should we join? One of Europe, where econonies are stifled under the growing beaucratic state? One of China, where freedom is a concept that may develop in the future? I choose neither, and I hope many more do the same in November.

I think SSL will be the future considering the fact that it offers many advantages like power saving and longer term reliability. But at the same the infrastructure around the power generation and distribution also shall be improved.

The market change to SSL lighting is, contrary to public and misinformed opinion, not government mandated on a national level, but subscribed to a global convention. The incandescent light bulb is not banned, but at the end of it's production in countries around the world. When countries such as China can make the change to SSL or the less expensive CFL technology due to the huge advantages for energy and the dependence on non-renewable energy, they now set the example while we, the US believe everything is big government and an infringement of our rights. We live in a global world. Turn on your computer and look around sometime.

Things like this should only be driven by the market. If you make a better mouse trap, the world will beat a path to your door. As soon as it is more economical for me to buy SSL, I will switch. Until then, you know who will be getting my hard earned dollars. For the government to step in and mandate the change is just more of our liberties evaporating.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
