CLI interfaces won’t die any time soon.
They require learning which is a big drawback. But they are simple to implement, simple to automate and once learned can be quite ergonomic.
I use Unix shell a lot – and I’m much more productive because of that.

Remez LED bulb with SunLike LED’s tested

I was pretty excited to click. Then I saw only the 5700k was reviewed. Any plans for reviewing the 3000k?

I’ll test the 3000K E14, but first I need to get an E27-E14 adapter for my sphere.

UV and IR for plants

Say what?

You want red and blue, not UV and IR (and not narrow LED spikes but a fairly broad range of each color)

I know this pictures since 2013. I need just real tests, not pictures.
Or you think that manufacturer and his huge buyer are stupid? Do you really think that they did not seen this pictures? Big Smile

Looking good. I’ll take a bit of over-saturation. Thumbs Up

Well flattening it can be useful when you want it to fit a flat screen. Here’s a little code from an old project of mine. Does this make me a flat earther?

function MapLatLonToXY($phi, $lambda, $lambda0)
{
$N; $nu2; $ep2; $t; $t2; $l;
$l3coef; $l4coef; $l5coef; $l6coef; $l7coef; $l8coef;
$tmp;

/* Precalculate ep2 */
$ep2 = (pow($GLOBALS[‘sm_a’], 2.0) – pow($GLOBALS[‘sm_b’], 2.0)) / pow($GLOBALS[‘sm_b’], 2.0);

/* Precalculate nu2 */
$nu2 = $ep2 * pow (cos($phi), 2.0);

/* Precalculate N */ $N = pow($GLOBALS[‘sm_a’], 2.0) / ($GLOBALS[‘sm_b’] * sqrt(1 + $nu2));

/* Precalculate t */
$t = tan($phi);
$t2 = $t * $t;
$tmp = ($t2 * $t2 * $t2) – pow($t, 6.0);

/* Precalculate l */
$l = $lambda – $lambda0;

/* Precalculate coefficients for l**n in the equations below
so a normal human being can read the expressions for easting
and northing
— l**1 and l**2 have coefficients of 1.0 */
$l3coef = 1.0 – $t2 + $nu2;

$l4coef = 5.0 – $t2 + 9 * $nu2 + 4.0 * ($nu2 * $nu2);

$l5coef = 5.0 – 18.0 * $t2 + ($t2 * $t2) + 14.0 * $nu2
- 58.0 * $t2 * $nu2;

$l6coef = 61.0 – 58.0 * $t2 + ($t2 * $t2) + 270.0 * $nu2
- 330.0 * $t2 * $nu2;

$l7coef = 61.0 – 479.0 * $t2 + 179.0 * ($t2 * $t2) – ($t2 * $t2 * $t2);

$l8coef = 1385.0 – 3111.0 * $t2 + 543.0 * ($t2 * $t2) – ($t2 * $t2 * $t2);

/* Calculate easting (x) */
$xy;
$xy0 = $N * cos($phi) * $l
+ ($N / 6.0 * pow (cos ($phi), 3.0) * $l3coef * pow($l, 3.0))
+ ($N / 120.0 * pow (cos ($phi), 5.0) * $l5coef * pow($l, 5.0))
+ ($N / 5040.0 * pow (cos ($phi), 7.0) * $l7coef * pow($l, 7.0));

/* Calculate northing (y) */
$xy1 = ArcLengthOfMeridian($phi)
+ ($t / 2.0 * $N * pow(cos($phi), 2.0) * pow($l, 2.0))
+ ($t / 24.0 * $N * pow(cos($phi), 4.0) * $l4coef * pow($l, 4.0))
+ ($t / 720.0 * $N * pow(cos($phi), 6.0) * $l6coef * pow($l, 6.0))
+ ($t / 40320.0 * $N * pow(cos($phi), 8.0) * $l8coef * pow($l, 8.0));

return $xy;
}

Edit: man the formatting went to heck.

Eh? You mean you need evidence to convince you which wavelengths plants use for photosynthesis?

You could do the experiment yourself; it would be a good science fair type project.

It was probably lost in translation, but I assume he meant to say “deep red” and “deep blue”. Not actually UV and IR.

Wow. I’m not sure if I ever want to see this light in person for fear of nothing else living up to it. That’s an AMAZING ~4000K spectrum. Wow.

Seriously. When are you going to get a contract to mass produce a bulb like these?

what?! Shocked

World government will kill me if I will mass produce bulbs like that

Now only like this in my shelter:

Even with a price reduction from economies of scale, I think they’d be a lot more expensive than the average person is willing to spend on a light bulb.

I remember SunLike speaking of these bulbs being designed to last a very long time. If my memory serves me well he spoke of 20 years.
Now I’m convinced that I want to have some but expected durability is a big factor in the discussion. If I can expect 5 years, I’d buy a few for fun uses. If I can expect much more I’d buy a larger volume.

Can someone independent who has a good idea of electronics share their thoughts on the topic?

If you had to guess, what would be the first thing to die in one of your bulbs? The LED or one of the driver components?

I have three or four LED 110v household bulbs that have died, clearly a driver component (multiple emitters visible, none damaged)
All of them are glued shut.

My brother gave me a small hair trimmer whose batteries were dead recently, it was refusing to work with a blinking red light. You could make it work by first plugging it to the power supply, turning it on and then disconnecting the supply's cable, but refused to work by itself on batteries. Its electronics raised the end of life flag, this means even if I had replaced its cells the thing wouldn't have worked.

On the other hand, I have a cheap hair trimmer which I overhauled with li-ion cells years ago, tuning its charging voltage for everlasting life. It also is noticeably more powerful than stock.

 

So, what are we paying for and why are we paying for?

People should completely stop buying carelessly, stopping this insanity.

I prefer to make good stuff. Anything which purposely reduces your vibration or that of what you do, is a disservice. As a consequence of looking at self interest beyond the highest good, it is skewed and leads to crash. Like being on drugs.
