I figured as much. I assumed I was seeing the 60hz flicker from the wall. I suppose it would be cheaper and last longer to not filter the signal. I imagine if the cap burst, the whole strand would be shot. Similar to the only series bulbs. One goes, the circuit is cut. I am sure a line conditioner is sold separate. In other words, a CAP in a box for $29.99.
TommyH, I think you meant candela, not candle power. The latter is considered an obsolete unit of measurement. Today, this is measured via luminance or luminous intensity. Wikipedia has a good article on luminance.
It looks like this may possibly be a breakthrough, or possibly not. I remeber the electro-luminescent panels and devices that we had in the 1960's and wonder if it is a new implemantation of that technology. Those devices did provide a nice grale-free light, but not that much of it. I have no ideas about the relative efficiency, or lumens per watt. But the devices were very long-lived. I think that they were sort of expensive, as well. I have a couple of the inverter packages that were used by Chrysler for the EL instrument panels back in 1965, I think. They put out a very spikey waveform with a peak of almost 200V.
It would be interesting to find out about the performance of an actual prototype, as opposed to that of a single research sample device. That is the sort of information that would help to understand where this technology lies, on the development toward commercialization curve.
I'm betting the reason ARS Technica didn't get "performance numbers" is because they asked the wrong question. So far, AFAIK, this is a number of prototype devices, not a single actual bulb with wattage specs, which is what will be produced after commercialization efforts are completed. The details that are available can be found in the (free) journal article, which we provide a link to. They include varying luminance intensities.
There seems to be some confusion here regarding the difference between prototypes and working products, and the amount of time it requires to move from the first to the second. I made an earlier comment on this subject: "Maybe we're all used to Silicon Valley-style announcements of new technology for sale right now in high volumes, and not of the long R&D cycle behind that technology. In materials technology, especially energy-related, development can take a long time...The main researcher has had a single working device for a long time--but not a bulb, and, presumably, a very expensive device, and, I'd guess, one he's been tinkering with as a prototype."
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
