They don't flicker with modern ballast.

It pains me to think how many terawatthours humanity has wasted through all of incadescent bulbs' reign...

And not flickering alone, fluorescents are a distaster for health in terms of both the flicker and just the light spectrum. Blue. As. Fuck.

You better be saying the same about LEDs as they are even more narrow band than fluorescents
The actual LED diode in white LEDs is a deeper blue with a narrower spectrum than the discharge from a fluorescent lamp

Oh yes, obviously, but at least they're more energy efficient and don't flicker as much unless you buy the cheapest chink shit with literally no driver inside.

I have a GE vintage style in that envelope with a real filament.

and they reverse engineered a 100+ year old edison style lamp, as the filament and support structure is identical.

Nice. Why don't we have LEDs this big in cars yet?

because that would take 150A to drive, and it's a complete waste of potential light output doe to shit optics and a rubbish led layout.
It would also be a fucking disaster to make it a DOT legal beam pattern.

If you take just one of those led chips, and pair it to a roughly 12in projector lens, it will kick the shit out of that whole setup in both range and spread.

There are not as energy efficient as you think
Replacing fluorescents with LEDs hasn’t been nearly as big as the jump from incandescent to fluorescents if there is any jump at all
For home lighting they are still comparing LEDs with incandescents because comparing to CFLs makes LEDs not look too impressive
Anyone who got memed into retrofitting there fluorescent fixtures with LEDs is going to have to wait a decade for a return from power savings
For full spectrum lighting in hydroponics and indoor gardening, LEDs are still struggling to make themselves relevant even just trying to replace T5s

Ah, a fellow homegrowman.

Bayonet fit bulbs are the worst idea ever. The glass on the newer bulbs look thin as fuck, making them liable to fracture, and slice your hand up.

They're more energy efficient than LED.

I just use LED. Cheap and they work.

Now undervolt it and make it last forever like the centennial bulb

I don't see EU-made non-halogen incandescents in offline shops now.

>Replacing fluorescents with LEDs hasn’t been nearly as big as the jump from incandescent to fluorescents if there is any jump at all
This tbqh, it's quite ridiculous too. My dad replaced every light in their house and threw away dozens of otherwise fully functioning fluorescents just to save 1.5 W with LEDs.

What a shit chart
LEDs only peak in blue because everyone just had to make them cool white in the beginning to make them look more brilliant. You can make ultra warm LEDs with no more blue than a tungsten lamp

All incandescent Aerotech bulbs here. You can get them in any wattage.

Man the high pressure lamps are beasts for the flux they deliver, even the tiny 150-300W used in home projectors. But yeah, don't drop one. And don't use one past its design lifetime, when they explode it gets nasty.

Here is the light spectrum for an LED quantum board
They only peak in blue when you decide to make them cool white, otherwise they peak near yellow/red

Attached: image.jpg (1900x1810, 1.22M)

As said before, early LED bulbs had the blue spike because they were pretty much all cool white. I believe the main reason for that was that with cooler light they're simply capable of a higher luminous flux, it was simply a marketing gimmick to put a higher number of lumens on the box. Once they actually made their way into people homes it became obvious that a warmer white is more desirable. A modern 2700K decent brand led bulb produces a really comfy light spectrum.

There are no xenon lamps in home projectors, they're metal-halide.

Spectrums still look like shit compared to incandescent.

>It's best to radiate most of your light in useless invisible infrared
Okay.

The $30000 Sony Qualia 004 that came out some years back, in pic above an old CRT pj, uses a xenon lamp. Over $3k a lamp from Sony, the cheapest replacement is the bare lamp from a third party with you reusing the old heat sink fins.

A very, very well made unit however compared to the 10lp chinkshit that passes for a pj nowadays...

I know but they principle is pretty much the same, both are UHP HID lamps. Xenons have a bit too much blue in their spectrum that's why they're not put in projectors by factory, there are people who mod devices to use xenon lamps though. Results are meh though due to the blue.

iMAX huh, they must be filtering out the blue light a bit so some of the power is kinda being wasted.

>not just using aut/o/motive HID xenon lamps strung up to ballasts around your house

The bare xenon for the Qualia 004:
asltg.com/product/qualia-004-replacement-xenon-lamp-3/

$900, which is more than the whole pj is worth at this point in time. That's why no other home pj used xenon.

Yes, also they produce very little sky glow.
Literally Gods gift to man for general outdoor lighting , and yet, they all have been replaced with shit. Literally shit.

I heard that infrared is good for eyes.

Yep they were perfect for outdoor, especially in areas where fog tends to appear. Car fog lights have to be yellow to help you see shit, with any cooler lights you're just creating a wall of light in front of you car.

Click click. Click click click bizzzzzz

I have never seen low pressure ones IRL, high pressure sodium are everywhere

Rather have high pressure sodium, you want some color at least

It's not that they're "good" it's just that they're low energy and generally don't do shit to your eyes unless at higher power, compared to stuff like ultraviolet that's dangerous even at low power. IR is simply wasted power.

Where are they used? I have read that they were used only before invention of HPS.

They were pretty much replaced in the 70s or something.
You can get the bulbs off amazon and drive them with fluorescent tube light ballasts. I built one for a yard light and its tits.
Fuck color Everything yellow. But seriously, just a little bit of supplemental lighting from leds, like 1/15th the lumens, and color comes back.

I had quartz iodine in my old 74 capri. The highbeams would illuminate objects in high earth orbit. I only ever see quarts halogen anymore.
Maybe they made them illegal.

Sorry I meant HPS too but the light produced by both is similar. The problem is that outdoor lights are being replaced en masse by LEDs that are a real disaster for this use case.

IR power is not wasted if you live in cold climate

That's just normal ass halogen incandescent, just using quartz instead of glass and iodine for the gas.
Doesnt really make it any brighter. Maybe you or someone stuck aircraft landing lights in for highbeam bulbs. A very popular thing to do back then but they had a very low hour life.

That's a big IF though. Canada/Alaska? Iceland? Russia? Maybe northern parts of Scandinavia.

They shit on the competition.

Sound and looks like something pulled straight out of 19th century but it's more modern than LEDs. Interesting.

Waiting for that user who posts a lighthouse bulb.

>just using quartz instead of glass
What

In Russia bulbs from 100w are sold as heat radiators, lol.

Fused Silica.
melts at a higher point then normal ass glass bulbs, but most are aluminosillicate now

I'm here.

They produce microwaves, so they're not popular.

They actually end up being worse than LEDs because of how human eyesight works at night time

That's a pretty outdated chart, LEDs are more efficient now. Also have to change them way less often

Yeah let's use all that power to heat the fucking ceiling
