very poorly written...why would LED need a filament?

The decorative bulbs with lower lumens are on ceramic tubes, possibly aluminum underneath. They look like the ones in your article. The market is filled with these. But these odd looking 150 watt equivalent dimmable LEDs are on an aluminum substrate, so quite a bit heavier than a normal bulb. They're quite a breakthrough in price and brightness for a normal E26 bulb size LED. The are the bulbs which made me try the conversion, an intro special at $22 each. The plastic diffuser does an amazing job of projecting the light of these two rings of LEDs in the same range as an incandescent bulb. When LEDs are spread out through the length of a fluorescent tube, there's not much heat engineering to be considered and the tubes are made of plastic.

As a result of the success in integrating LED lighting is a reason the DOE is evaluating DC supplies to office building and homes and allocate grants for innovative ideas. As solar panels are a DC source and it seems that 48V will be the standard, it all meshes in nicely. Unfortunate most utilities are resisting those changes because their investment also in infrastructure The sad part is that manufacturing LED's for lighting is a very competitive business with thin profit margins. All in all I think we are moving to a mixed world of DC and AC

One of things I originally missed when LED technology took off as a lighting source was the significant reduction to the cost of growing vegetables indoors. In this at least a further 50% reduction in energy cost of LEDs is worth noting. It is probably not enough yet to disrupt the whole model of seasonally shipping outdoor grown vegetables around and around, but for the hobbyist indoor gardner at least it will be a great breakthrough once it hits the market...
