I like to know progress from other vendors - GE to be specific. This scientific testing is very good, however, did they established test crtiteria for human response to this LED lamp? (CRI) is one of them).
Is EETimes is going to conduct investigation of inside this Philips LED bulb?
There is a requirement for cost. It is to be 22 dollars in the first year and dropping to 8 dollars by year 3.
The lifecycle cost of the bulb will be lower than for CFL based on the long life of 25+ years.
Some of the questions I have:
-Was there a L-prize requirement for the cost?
-When is this expected to be available commercially and what is the price?
-How does the cost-benefit for the LED bulb compare with the same for CFL?
It's very tempting to try to do head-to-head comparisons between CFL and LED technologies, but I would think that the real win with LED is new form factors for lighting. Why are we still forcing new technologies into 120 VAC screw-in sockets instead of looking at alternatives? Area lighting via panels and pinpoint beams in appropriate places are two possibilities that come to mind right away.
I find it interesting that current CFL bulbs replacing 60W incandescent bulbs start virtually instantly while those replacing 75+ watt bulbs can take minutes to come up to full power. Is this because prizes were offered for 60 watt (but not 75 watt+) replacement bulbs? Will we see similar dramatic differences in performance of LED bulbs between 60W and 75W incandescent replacement bulbs?
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
