I've just published a blog post about this: https://blog.plover.com/tech/corn-bulbs.html

I would totally support a crowd-funding of a company for making such an arrangement accessible to people around the world, using flat-packaged parts and installable by mere mortals.
... preferably with the blue-scattering effect as well :-)

R9 is also important in the higher CRI ranges. CRI is based on pastels - it's an artifact of measuring traditional florescent bob performance - and R9 captures the vivid reds that are important to truly accurate color rendition.
Just from the scale I think it's clear that CRI is not that good a measure. As you say, CRI uses rendition of a dozen or so colors as a measure. The scale is heavily compressed - orange sodium vapor streetlights which are almost monochromatic "achieve" a CRI of 30, which is nowhere near "colors are 30 % good". Similarly, mercury vapor lamps have a CRI of around 50, and yet are complete garbage. All cheap LED fixtures…

The issue I have is that being outdoors is distracting due to constantly changing environment. If I'm trying to deep focus on something, it doesn't help. Even worse if the environment is somewhat uncontrolled (wilderness, city cafe) as there are potential safety issues if I truly deep focus. If I'm doing meetings, talking to folks, churning through a bunch of bs tasks, etc. then it's nice.
So far I've been learning this takes time to get used to (i.e. trying for multi-day streaks of trying to work outside), and: - The ergonomics / screen setup really make a difference in whether you can tolerate being there for 1 hour versus 4 hours. - I've been pretty intentional about finding spots that have are quiet with some constant (e.g. creekside babbling), if really needed headphones can help deal with wind no…

One doesn't need to make lights out of led strips, shop lights have transitioned to LED. $20 each, https://www.harborfreight.com/5000-lumen-4-ft-led-hanging-sh... 5k lumens, 60w I also came to post the DIY perks video about simulated sunlight, the effect of parallel rays really changes the geometric mood of the room.
It really does help. Just don't keep working into the night under them, because whoa boy - talk about sleep disruption. Those nice bright lights make it surprisingly easy to work until 6am and not even realize it.

>>It's not so much an idea as a piece of software, but being predicted on wasting energy it's going to do a lot of harm. That's an example of this class of game-theory based ideas. It's not a waste if the product the PoW generates is valued as equal to or greater than the cost of generating the PoW, and the market ensures that is the case, as miners cannot operating at a loss. Where it can be socially harmful is when…
Money laundering is useful but that doesn't mean it's good. A Ponzi scheme can generate wealth but it can't generate value. Wealth without value is maybe not wasteful, but it is harmful. > Where it can be socially harmful is when energy consumers don't pay for the cost of the negative externalities that the energy they purchase created in its generation, but that applies to all energy usage, not just that used in gen…
2. Money laundering can improve economic efficiency when the crimes that generate the illicit revenue are socially beneficial, as is the case when people in China escape the Communist government's capital controls, or when people in Venezuela escape their Communist government's steep inflation tax via mandates to use the state's fiat currency.
Even in ostensibly free societies, socially harmful laws that repress the right to voluntarily interact, like price controls on N95 masks that prolonged a shortage in them for months, or heavy taxation to pay the pensions of a bloated and over-paid public sector kleptocracy, can be socially beneficial to undermine.
So your deduction that money laundering or other forms of escape from institutional rules, is socially harmful, is overly simplistic. In some cases it is harmful, and in some cases it's beneficial.
3. Cryptocurrencies are by definition not ponzi schemes. You could argue they're speculative bubbles, but that is itself speculation.
>>Bitcoin alone uses as much power as a medium-sized nation.
Because it generates billions of dollars of currency a year, and its production is costly in energy and affordable in labor. The energy consumption of labor-intensive industries obfuscates the real energy requirements of those industries, by effectively outsourcing the energy consumption to the workers.

How cold is coldish?

I used "rails lights" (the kind they often use in boutiques) and pointed them up at the ceiling (rails are mounted on walls, not the ceiling). There is almost nowhere in the apartment where you can look directly at a light source. The result: bright but pleasantly diffused light.
Very cool. I had considered something like this: install "crown moulding" a few inches shy of the ceiling and running rope lighting along where it will not be seen — but can scatter across the ceiling.

According to what I've found, grow lights can emit enough UV rays to make them (unfortunately) a non-starter for inside your home.
Looks like for LEDs at least that is not true: "commercially available LED light sources (for horticultural or other applications) can be considered human safe when designed, installed and used in accordance with the applicable standards, regulations and manufacturer’s instruction" https://www.valoya.com/the-effect-of-led-grow-lights-on-huma...
