Re: LED lighting flicker
LED is getting popular in TV, Lamp, factory lighting, and commercial building. Engineer might look at the electrical requirement above mid-power. I have a still question regarding how high power LED could be reliable and robust compared to halogen lamp (600 Watt@120 VAC). It could be possible that LED color might be changed due to the age or other factor related to led driver.

Re: LED lighting flicker
It's not just turn on the light, you have the control part as well, that makes the spectacle becomes even better .... How long will they have the return on investment by the previous consumption?

That may not be the main factor. I think LED is competing on its quality by giving a higher denser and quality lighting than alternatives.

Re: LED lighting flicker
The first use of 3D camera was in Superbowl. Now, LED lighting is making way. It just tells that Superbowl is bringing lots of innovations and technologies in the game besides the elite athletics that play the game.

Re: Great News!
 one of the major disadvantage is the cost of the LED lighting specially when it comes to the household usage.

@Ranasinghe, I think this cost will eventually come down as more and more people adopt LED lighting.

Game Changer?
I'll be even more interested to see if the new lighting provides any advantages to team offenses versus defenses. The rules of the game have been so liberalized over the last 35 years to boost offensive stats by tying both hands behind the defenses' back, that we're not even talking about the same game anymore! That's beyond playing in controlled conditions (domed stadiums, warm-weather sites). Last year (2013) Seattle's defense confounded those liberal rules, basically for an entire season as well as for the championship game. Can they do it again tomorrow?

Yes dassa.an increase of usage of the LED lighting is happening because of the high level of energy saving. And also cot can be barred by the commercial industry.

"LED lighting has its own advantages, another advantage is low power consumption and less fluctuations."
Yalanand its true and one of the major disadvantage is the cost of the LED lighting specially when it comes to the household usage.

Re: LED lighting flicker
@tzubair: Hence, DC! DC low-voltage circuits are notorious for dropping voltage over the distance of a wire run, though, so you also have to take that into account, whereas multiple parallel reverse-biased diodes at each LED will allow the length of wires to be AC, thus minimizing the affects of voltage drop.


Nice idea! DC seems to be the way to go. AC power transmission losses are greater than DC losses. That is hardly an industry secret. In fact the reason you can wirelessly charge a cell phone is because any changing current will radiate away some energy. You just need to coil the wire up to gather some of that energy in a convenient place.
