As much as I would like the coffee table version, I don't know that the long form and fairly technical nature is suited to that style.

Thumbs up everything about this product. I just started a side project that has minimal interface goals for a low(er) tech use case, and this is lovely.

Reminds me of an experiment in my undergraduate glass lab. Take soda-lime stirring rods and break 50 or so under 4 point bend test. Record strength. Take another batch and simply log-roll them along the lab bench for half a meter. Repeat br

:-) true enough, and I'll take you up on that. Especially if you sold a wireless mesh company and know a guy named Eric from your GT days who recently changed jobs from one consultancy to another...

Wait. I think I am supposed to grab lunch with you through our mutual friend Eric S. Does this sound familiar?

Minor pedantry: 10log(6/100) = -12.2, so you could sort of get the number stated if you assume they meant sound power. These metamerial, interference based approaches, are not going to be broadband by the standards of physical acoustic

You could also add the asymmetrical waveshape of the "blat" of several types of horn instruments (e.g. trombone) to that list of similar tones.

Generally I would agree that if you exercise this muscle, it can be hard to turn off. There's still a lot of room for art in the process, though. With experience you get less attached to your particular sonic leitmotifs, and that helps

I'm not speaking of the sensor, but rather the meat computer interpreting it. Things you can train for include: being sensitive to minute changes in level/frequency/time, picking one source out of many, precisely placing item

As someone who has nearly two decades moonlighting experience as a live sound mixer, stories like this remain a reminder at how bad humans are in general at hearing. These two instruments are both great, but the Hammond is no analog for a p

I'm not sure for high CRI. See my comments elsewhere about Ikea otherwise.

Any bulb with switch mode hardware to control the LED drive current will exhibit RF emissions. The cheaper bulb in the original article has linear current control. Inside the ASIC, this could be as simple as a BJT or FET in saturation with

Leedarson is an OEM for many light bulbs you've seen on shelves in stores.

Can't speak to any of that. The appearance to me as a consumer walking around with an engineering eye, is that the early days of expensive higher end, store exclusive home LED bulbs (e.g. Cree at Home Depot) has given away to an all ou

As above, look for architectural bulbs that are deep dimming rated (< 10% dimming). They cost more. I personally have had good luck with Cree, but probably the other top shelf vendors have similarly good products.

There's a myriad reasons why flicker and buzz occur, because there are a number of ways to achieve dimming. But all of this comes down to cost. If dimming is important to you, there are a number of architectural grade bulbs that offer

We've certainly been asked about amber LEDs for coastal environment projects, so I think there is some demand. Amber LED performance, on the other hand, is a different story. The lumens out of a legacy high pressure sodium lamp are ver

I can only guess that the marketing department wanted to put the biggest numbers forward against what was plausible calculations for the early LED lifetimes. I know for a fact that some of the testing houses have done extended on/off c

It has nothing to do with this. It has to do with details about the OEM for the Ikea product.

All bulbs produce heat, both from the LEDs and the electronics. Incandescent bulbs were blazing hot, too, and they radiated IR on top everything else. A high efficiency LED assembly is still producing on the order of 50% light and 50% heat.

I cannot speak knowledgeably to this for A19 type products, but generally there is no need to have such low temperatures to achieve good lifetimes. There may be temperature requirements this low for bulbs mounted in certain locations, but t

None. Our industrial customers require minimum 5 year warranty at 12hrs on per day, 365 days per year. We work hard to make both the lighting producing and mechanical aspect of the luminaires last.
