Those look to have ~80 CRI. Having used LEDs with 80 CRI and ~93/94 CRI, I can absolutely tell a difference. I would prefer 90+ CRI, but those don't really seem to exist yet.

The writer of the original article should be shot, hung, shot, and then boiled.
The writer may very well have twelve inches, but that's not important here. What's important is the past tense of "to hang" (in the sense of putting a man on the end of a rope) is "hanged"....
I just made another post about this, but I have about about 15-16 cree bulbs in my house. I take a picture of the receipt and the packaging at the time of every purchase.
I've had trouble with two--both 40W TW series bulbs. These bulbs flickered--they would turn off and if I adjusted--or even tapped on the bulb--the bulb would come back on for a time. The problem got worse until they barely worked anymore. I thought it was the fixture until I tried one of the bad bulbs in a desk lamp and had the same issue.
Anyway, I emailed Cree tech support with the photo of the receipt and packaging and had 3 new bulbs fedexed to me two days later.
I'm annoyed by the quality lapse (less than a year), but I don't have any problems with their response.
That's what I'm really hopeful for--a dimmable, high-CRI, 100W equivalent LED.
Hmmm, interesting. I've upgraded almost my entire house to Cree bulbs over the last two years. I had one fixture that had three 40W TW (high CRI) bulbs--the only 40W crees I've used--that were all bought at the same time. Two of the bulbs died within a week of each other--they flicker off and if you tap them will turn back on. I'm assuming some solder or some other connection has weakened. I'm going to try to fix them, but that's neither here nor there.
I emailed Cree support with a picture of my receipt and a picture of the original packaging (taken at the time I purchased them). Cree immediately offered to Fedex me three new bulbs (including a replacement for the third bulb) and did not even ask for me to send the old bulbs back. I had new bulbs two days later.
I'm disappointed that the bulbs didn't last that long, but I couldn't ask for any better response out of Cree's support.
Try the Cree TW series bulbs (a few more bucks per bulb, and a few more watts). They're still not perfect, but they're much better.
A flamethrower is primarily useful for clearing bunkers.
Squirt a jet of flame through the firing slit on a concrete bunker, and it quickly ceases to be a threat to the guys on the outside.
Like a demolition charge, it's utility is pretty limited, but when the right (or wrong, depending on perspective) situation comes up, there's no substitute....
Interesting that you'd pick those names. A quick google for wealth of US Presidents (adjusted for inflation), puts Bush at 15 (the elder) or 17 (the younger).
And this is as opposed to, say, John Kennedy (1), Lyndon Johnson (7), FDR (9), Clinton (10), who all have that peculiar D after their name.
And note that Obama is #21. Hardly poor by any definition of the term....
Note that I ignored the rest of the top 10 because they served far enough back that the Party they were part of had no real similarities to the current version of the Parties of the same name (once upon a time, the Republicans were the anti-slavery Party, not the Democrats, for instance).
That is silly. A falling bullet has a much lower speed than one that was just shot. I've been hit by shotgun pellets at the end of their range, it was like having gravel slung at you.
A returning bullet CAN hit someone, and possibly injure them if everything is lined up right, or there is a very low angle of fire, but they have a small fraction of the energy they had in the first km after being fired.
a good discression
I really hope you meant "an indiscretion" here, otherwise I have no idea what you're talking about.
So, enquiring minds want to know: are you semiliterate, or are you trying to say something else entirely?
...but they get our shit to space.
What I find more interesting is why stars rarely collide?
Too much empty space.
Consider that for two stars to hit each other, they essentially have to pass within one stellar diameter of each other (absent gravity, but they're moving at over escape speed relative to each other, so gravity won't enlarge that distance a whole hell of a lot).
So, one stellar diameter is ~1.4 Gm for Sol. Nearest star is 40,000,000 Gm away. If that nearest star were headed toward us (it's not), it's course would have to be within 0.01 seconds of arc of our Sun in order to actually hit it.
And stars farther away have an even smaller course window to be in to smack us....
Some of us are doomed even if most women don't know this secret.
What you describe is pretty much the way the US was originally intended to be. The Feds handle standards (like weights and measures) and foreign policy, pretty much everything else handled at the level of the individual States.
Alas, the Feds have been working hard to move every decision to Washington for a long time now, whether it makes sense to do so or not....
Because then everyone dies when the computer fails. Autopilots regularly fail and expect the pilot to take over
I think this depends on your definition of "fail". As far as I know true computer failures where the machine just goes crazy and tries to crash the plane are non-existent. What happens more regularly is the autopilot sees that something weird is happening and chooses to disengage itself - presumably an autopilot program could be written that never disengages and always does the best it can to fly the plane, unless deliberately disengaged.
This is particularly problematic when sensors fail, as they did in AF447, and the computer doesn't know what's going on any more.
No, this is irrelevant. If the planes sensors completely fail then the pilot doesn't know what's going on either, and the plane is probably doomed no matter what. In normal operation these planes are flying in a very small speed corridor between disintegration and stalling. If you don't know how fast your going a stall or overspeed is pretty much inevitable, and if you don't know how high you are even basic visibility problems can cause a crash into the surface. Neither human nor computer can succeed in such a situation.
