Trump blames LED lightbulbs for making him look orange

It’s just his evolution into the personification of Satan.

Watching bigclivedotcom dissect some iffy LED light or other device is like slasher flicks for me.

That’s just another word to describe the same judgment.

My question remains: what are the qualities of a spectrum that make it more or less desirable?

The amount of dodgy electronic doohickeys that pass his desk is just astounding. He’s a brave man.

Republicans are far more comfortable with the predecessor to electric lighting: gaslight.

It’s not enough they gain, others must lose.

It entirely depends on what you are trying to do with it.

If you are trying to perceive the colors of something as accurately as possible to the human eye, you want to mimic the spectrum of sunlight as closely as possible.

If you want to measure color scientifically, you want a completely flat spectrum across all wavelengths.

If you want the brightest illumination without regard for color rendering, you don’t care about spectrum, except that human eyesight has the highest sensitivity at 488 nm.

If you want to be able to see things at night without disturbing wildlife, you want illumination in the reds, since many animals are not sensitive to it.

If you want to reduce perception of your shitty spray tan, STOP USING SHITTY SPRAY TAN!

I like my LED’s, but need incandescents for things like reptile heat bulbs. It’s become harder and harder to get certain wattages.

Listen, I know they’re inefficient light wise. But… if the heat is the point, they’re no longer inefficient right?

Should you get more efficient reptiles?

They run off of insects that I raise on kitchen scraps, so the system’s pretty efficient overall…

It’s just that whole damn being an poikilotherm thing…

Have you ever seen how some crystals and gemstones glow under UV light? For instance, you have to move a lot of dirt in order to find Opals. They are not all chipped of the mine wall with a pick. In Australian opal mines - at least the more mechanised ones, they suck the dirt to the surface with giant vacuum blowers and pass the sifted dirt via a conveyor bet through a dark chamber on the surface that is lit by UV lights, thus more easily exposing the opals. It’s some poor saps hot and dirty job to pick out the gems as they pass - stifling, but very lucrative.
I think you will find this illuminating:

I have two 60W-equivalent LED bulbs (the original Philips flat-design 800 lumen) in each of my garage door openers and they’ve been doing fine for a few years now. A properly-designed LED will have almost nothing inside which will fail under reasonable vibration. Besides, if your opener is working properly it really should not be vibrating much at all.

This is already done by halogen lamps, most are 12V and a normal transformer, by the way powering leds with AC shouldn’t be a big problem, because either using a rectification bridge or putting diodes on both polarities will solve the problem. For special application there are also 24V halogen lamps with Edison threaded plug. If a circuit is made for led lamp specifically there are constant current modules specially designed for LED fixtures.

What I have noticed is that normally brand name lamps, even for incandescent, are better and last longer than no-name ones. For different reasons cheaper construction means less reliability, on LED cheaper capacitor and simplified circuits, for halogen less damping and more fragile supports.

Not to derail the conversation, but in your case you may want to look into panel or enclosure heaters. We use them in outdoor panels for temperature and humidity control. Do you need light all the time you need heat? They come in different wattages and are usually shielded.

Efficiency wise, yes all electric heaters will produce 3.41 BTUs per watt. All electric heaters are actually 100% efficient, but the cost to power them makes them more expensive than other fuels.

Are you sure those crickets don’t fart tons of CO2?/s

No, the voltage on mains, whether 110VAC or 220VAC is incompatible with LEDs without a circuit in between to knock the voltage down to 7-10V at the individual diode level.

Also, I’ve seen LEDs running at 60 Hz AC and alternating polarities, and you can definitely see the pulsing. It’s absolutely not acceptable for lighting purposes. Don’t forget that incandescent and arc lamps like halogens just need to get hot; the electricity isn’t directly generating the light. While there is flicker if you use sensitive high-speed cameras, there is enough lag in the temperature drop from one peak to the next that we don’t perceive it. LEDs are directly driven by the current flowing through them, so you see everything going on with the electrical input. There’s no lag, so you see every pulse.

In that case I hate it when conservatives punch themselves in the face repeatedly.

It’s a neat effect for x-mas lights on the outside of your house. It’s absolutely sickening for indoor lighting purposes.
