Halogen lamp bulb

Because of the new components, these advanced lamps were originally referred to using the term: quartz-iodide. Replacement of the lower-melting glass by quartz was necessary because the halogen regenerative cycle of the lamp (discussed in detail below) requires the envelope to be maintained at a high temperature (in excess of those tolerated by ordinary glass) to prevent tungsten halogen compounds from solidifying on the inside surface. In addition, minute amounts of iodine vapor were sealed inside the envelope. Tungsten-halogen lamps were first developed in the early 1960s by replacing the traditional glass bulb with a higher performance quartz envelope that was no longer spherical, but tubular in shape. Likewise, the loss of tungsten from the filament reduces the diameter, leaving it so thin that it ultimately fails. Over time, the lamp output diminishes as the residue of deposited tungsten on the inner envelope walls grows thicker and absorbs increasing amounts of the shorter visible wavelengths. The major concern with tungsten lamps is that, during normal operation, the filament continuously vaporizes to produce gaseous tungsten that slowly reduces the filament diameter and eventually solidifies on the inside of the glass envelope as a blackened, sooty deposit. In contrast, tungsten has a melting point of approximately 3380° C and can be heated to almost this temperature within a glass envelope to generate light having a higher color temperature and life span than any of the previous materials used for lamp filaments. Carbon lamps suffer from rapid vaporization of the filament at temperatures above 2500° C and thus, must be operated at lower voltages to produce light having a relatively low color temperature (yellowish). These advanced filaments, which could be looped, coiled, and operated at very high temperatures, were found to be far more versatile than their carbon and osmium-based predecessors. The first commercial incandescent lamps equipped with tungsten filaments were introduced in the early 1900s. In long-term experiments (typically, those requiring hundreds to thousands of image captures), this lamp is particularly stable and is subject to only minor levels of temporal and spatial output fluctuation under normal operating conditions. For imaging living cells with contrast-enhancing techniques (principally differential interference contrast ( DIC) and phase contrast) in transmitted light compound microscopes, the most common light source currently in use is the 12-volt, 100-watt tungsten-halogen lamp. Stereomicroscopes also take advantage of this ubiquitous light source in both entry-level and advanced models. Polarized light microscopes used for particle identification, fiber analysis, and birefringence measurements, as well as routine petrographic geological applications, typically use high power tungsten-halogen lamps to provide the necessary light intensity through crossed polarizers. They are excellent for brightfield examination, photomicrography, and digital imaging of stained cells and tissue sections, as well as numerous reflected light applications for industrial manufacturing and development. Several varieties of tungsten-halogen lamps are now the default incandescent illumination source (and are provided by the manufacturer) for most of the teaching and research-level microscopes marketed around the world. Due to their relatively weak emission in the ultraviolet portion of the spectrum, tungsten-halogen lamps are not as useful as arc lamps and lasers for examining specimens that must be illuminated with wavelengths below 400 nanometers. Tungsten-halogen lamps, the most advanced design in this class, generate a continuous distribution of light across the visible spectrum, although most of the energy emitted by these lamps is dissipated as heat in the infrared wavelengths (see Figure 1). These features are primarily responsible for the widespread popularity of incandescent light sources in all forms of optical microscopy. Tungsten lamps are relatively inexpensive (compared to many other light sources), easy to replace, and provide adequate illumination when coupled to a ground glass diffusion filter. Older lamps equipped with tungsten wire filaments and filled with inert argon gas are frequently used in student microscopes for brightfield and phase contrast imaging, and these sources may be sufficiently bright enough for some applications requiring polarized light. Incandescent light sources, including older versions with tungsten and carbon filaments, as well as the newer, more advanced tungsten-halogen lamps, have been successfully employed as a highly reliable light source in optical microscopy for many decades and continue to be the one of the illumination mechanisms of choice for a variety of imaging modalities.

They are known as "tall standing lamps" because in general they are quite tall, either a little shorter than an average person or slightly taller than an average person.Ī typical average floor lamp will likely be around 60-72" in height, i.e. Pole lights come in variety of styles.įloor lamps range in height anywhere from around 4 feet to several feet. With tall lamps you can raise the level of light in any room using a standing lamp. This strong light output is useful for tasks and activities in the room. a table lamp, and also tends to support a higher wattage of light bulbs.Ī standing lamp may feature 2 or 3 light bulbs, with a total wattage of 300 watts or more, providing a much stronger light in the room. The floor lamp tends to cost more in general than e.g. Since tall standing lamps tend to be more substantial, with a larger base, tall pole lamps usually feature larger lampshades to maintain proportion. In this case the lamps are best placed further from where you are sitting, or behind you. When seated, it sometimes becomes possible to see the interior or underside of the lamp, which may expose bulbs to the eyes. The shade on the floor lamp shields your eyes particularly when it is close to eye level when standing. Tall lamps are usually taller than table lamps.īy positioning the light source so high in the room, a floor lamps allow the light to either be directed toward the ceiling, or downwards over some seating or desk area, or both. Usually the lamp head or light is at least at chest-height, through eye level or even taller than a standing person. Floor lamps often double as floor reading lamps and some reading lamps are specifically designed for this purpose.įloor lights stand tall in a room and are much taller than other types of lamps. A wide variety of designs and styles are available, using technologies such as led floor lamps, fluorescent floor lamps and halogen floor lamps.įloor lamps are often positioned either in the corner of a room or behind a seating area since the increased light is useful for performing activities, reading and so on.

do not touch J-type bulbs with bare hands because high temperatures may crack the quartz bulb if it has been etched with oils from hands and fingers. Because of their high operating temperatures and unique bases, thermal control and socket design within the fixture are important. They may be double or single ended and are available in a variety of lengths and wattage. These gases, along with a small filament of tungsten, are encased in a. Tube-shaped halogen bulbs (J-type) are made of quartz glass to withstand high operating temperatures. Halogen bulbs consist of inert gases and a halogen gas (bromine or iodine, for example). Most halogen bulbs use about one-quarter less energy than the standard incandescent, but recently some halogen lamps have entered the market that use half the energy of standard incandescents. Xenon lamps are very similar, except that xenon gas is used instead of halogen. These types of bulbs are also known as quartz iodine lamps or tungsten halogen lamps. Halogen infrared (IR) bulbs also have a reflective coating to redirect infrared energy back onto the filament to save energy. 360 Lighting Modern Table Lamps 14 1/2' High Set of 2 Touch On Off Switch Silver Metal White Drum Shade for Bedroom Bedside Office. Halogen light bulbs are incandescent lamps that contain a small amount of bromine or iodine added. Halogen bulbs have an inner capsule that contains halogen gas, which extends bulb life. Halogen screw base bulbs fit into the same medium-based sockets as common incandescent bulbs. Halogen bi-pin bulbs only fit into fixtures designed exclusively for their use. Some halogen bulbs have a pin base (bi-pin). Restrict their use to applications where short hours of use are expected, or where there are no other alternatives. Thats to say a halogen will appear brighter than an incandescent of same power (watts). However, halogen bulbs offer significantly lower efficacy and shorter life than fluorescent and LED bulbs. Answer (1 of 11): Generally speaking, halogen bulbs are more efficient than incandescents. Due to the addition of halogen gas and in some products a coating that reflects infrared energy, halogen incandescent bulbs are somewhat more efficacious (the amount of light produced per unit of input power) than common incandescent bulbs.

Government Asset Soap! This is half of the last part (the smut got too long and I wanted to post this dammit).

Original concept comes from @ceilidho’s military asset Soap. Further inspiration came from @391780’s Nikto version “The Summons”. Both are very good and you should definitely check out!!

Content: Post-trauma coping, Non-Con Touching and Kissing, Violence (mentioned), Unstable Soap

It’s probably a fire hazard, the candles. They’re sprinkled across your little cabin like fireflies, feeble but steady heartbeats of a home you’re failing to build. Too many of them, likely. Two, sometimes three, per room. Tiny tealights, smokeless soy, scented pine. It would be easier, safer, to just turn on the lamps you foolishly invested in.

You can’t bear anything brighter than golden halogen anymore, though. The glare drags you back to a tiny cell bisected by cruel metal, holding back an even crueler fate. No, you’d much rather wade through pools of shadow and firelight, fire code be damned.

It’s a small cabin, but you’ve already cluttered it up with furniture and rugs, a theme for each room. Yellow and blue for the kitchen. Purple and cream for the den. Green and brown for your bedroom. Nooks to hide in, spaces to squeeze into, big shapes to huddle behind. You’ll never be caught out in a cold, barren room ever again.

Your days are long regardless of the time of year. Get groceries in town every day, making a point to be friendly and seen so that someone might notice if you suddenly stop coming. Clean incessantly, so many surfaces to dust. Pick hobbies like daisies. Knitting and crocheting, different paint styles, felting. You’re contemplating carpentry, would like to build shelves for all the books stacked up in the den. Keep a dream journal by your bed that you neglect for weeks at a time.

You draw out the nights until you can count the hours until dawn on one hand. Stay up baking, making homemade ink, learning new ways to style your hair, anything, anything, anything—

It’s not the sleeping – or at least that’s not the worst of it. It’s the waking.

Laswell suggested a cat.

You told her to stop suggesting pussy to unstable people.

But it’s still not a bad idea. Another living thing to keep you accountable; the plants are pretty and time-consuming, but not good company.

You talk yourself out of it every time, knowing the worst-case scenario. It’s not catastrophizing if it actually happens, and you can feel an invisible time weighing on your shoulders like another gravity. Tick, tick, tick. Heavier, heavier, heavier. It’s hard to breathe beneath the wait.

The military doesn’t do apologies. It does platitudes at best. Well wishes and good intentions are painted in brushstrokes of blood. Victory flags are planted on bodies, living or otherwise. Laswell apologized. She swore that if there had been another way – any other way…

She didn’t promise to leave you alone. Didn’t assure you that you’d never see her or her goons again.

If you thought it would do any good, you’d tip one of the candles over and set it all aflame. Rebirth through fire. But you never did figure yourself for a phoenix. And besides, a phoenix is still itself, even when the ash falls away.

So, you spool out your time like picking at tapestry threads, one thin string at time.

Tonight, it’s bread. Cinnamon chocolate babka, to be specific. You were craving something sweet. Are debating the merits of some sort of cream cheese icing while you shower off the long, ever-busy day.

Have decided on an optimistic why not as you slip out to begin your overly complicated self-care routine. Moisturizers, hair oils, lotion. An unexpected benefit of overloading yourself, you suppose. Even when you first got out of the military, you didn’t take such good care of yourself. You have a jogging route now. You’re handling your trauma every possible way except therapy. (And sleeping.) Better than nothing, you figure.

The candles have gone out in your bedroom. You click your tongue in annoyance, trying to remember where you left the matches this time. Bedside table?

You pad across the soft carpet, using the edge of the bed as a guide in the pitch black. The only other problem with candles is that their humble light doesn’t reach very far. But you know this house and keep the floors tidy enough that you’re confident you won’t trip.

Make it to the nightstand without incident and pat around. Knock the side of your hand into the little carton and only just catch it before it hits the deck. Let out a little huff and start to fumble it open.

“Nice catch, bonnie.”

You gasp, but your voice doesn’t get any farther than the back of your tongue. The box slips from your numb fingers, matchsticks scattering across the floor. He tsks.

“Shame that. We’ll get ‘em later.”

You can’t move. Can barely breathe. You’re just frozen, heart thundering with a sudden storm of fear and confusion. Hands still aloft in front of you, spine rigid, knees locked.

You feel more than hear movement behind you, and then the warmth of his body seeping into your naked skin. Not quite touching. Not yet.

“Missed you, little bird,” he rasps in your ear.

You always thought that in a moment like this you would scream. Kick and elbow and fight, damn your certain loss. But when it comes down to it, survival drowns out all those stupid, haughty ideas about pride and dignity. So you don’t curse and shout like you always fancied you would.

You whisper, “Soap.”

He hums but it sounds like a growl in your panicked state. “Missed me too, aye? You’re already naked fer me.”

His hands are searing when they settle on your waist like they belong there. He pulls you back against him; in the dark he’s bigger, broader than you remember. At least, you think, he’s fully clothed for now.

“What are you… how are you here?” you ask.

He barks a laugh, mean and rough. “Was only a matter of time after that shite they pulled.”

You squeeze your eyes shut and see it recreated in the phosphenes behind your lids.

Soap buried balls deep inside of you, murmuring a constant stream of filth as he got harder and harder inside you. Filling you up as you twitched around him, oversensitive and teary, afraid of what would come next.

Then the lights flashed, flicked red. An alarm sounded, Laswell’s voice ordering Soap away from you. But he just snarled and hunched over you, hips snapping to bury himself right back inside while you cried out.

The locked door swung in, armed guards swarming in. Yanked Soap off you while you scrambled to cover yourself. Someone grabbing your arm none too gently to pull you from the room. Soap wild-eyed and snarling like something possessed, until he was overtaken by struggling guards and you were trembling naked in that damned hallway.

“Was mad at you, at first, cannae lie,” he says, almost conversational. Your eyes snap open, though you know it’ll do you no good. “But I’ve had time to think on it. Wasnae yer fault, was it? Saw them drag you out.”

An awful relief floods you. Fuck dignity, fuck honesty. This is Soap right behind you, completely unrestrained and unsupervised.

“Yeah,” you answer, voice small. “I didn’t know they would do that. What… um. What happened to you?”

He presses his face into your damp hair, pressing closer, snaking his arms to squeeze you against him.

“Sent me off on some shite mission,” he explains, “probably hoped I’d die out there. You smell so good, lass.”

You shiver as his breath ghosts over the sensitive skin of your neck. Hot, humid.

“And… and then what?” you insist, trying to stall.

You’re not sure what you’re stalling for. There will be no miraculous saves here – not that you really got any last time. It’s not like there’s any real plan to be made here, either. None that you’d be confident enough to risk his wrath on.

“Disappeared. Took care of business. Came to get my pretty little bird.”

A rough hand trails over the curve of your hip, brush the neat curls of your mound. You suck in a breath, hands twitching with the urge to stop him but not sure of putting up resistance when you’re still unsure of his mental state.

“And what about you, hm?” he rumbles. “Been a good girl while I’ve been away?”

His fingers dart down towards your entrance, not nearly prepared for anything. Least of all his thick digits.

“Y-yes!” you yelp, grabbing at his wrist. Relief makes you dizzy when you manage to stop him. “I-I’ve been good. Which means I’m not… I can’t just take you. I need… I need prep.”

He huffs, nips at the tender spot beneath your ear. The thrill that shoots through your stomach is terrifying.

“That’s what these are for, bonnie.”

And to your horror, he starts to push past your resistance like your staying hands aren’t there at all.

“John!”

He freezes. You shudder air into your burning lungs, feeling dizzy on panic.

You can get through this without pain, just think.

“I haven’t even got to see you,” you stutter, voice shaky. Can’t quite inject the disappointment you’re trying for, but hopefully it’ll work. “And I bet you’re all dirty from travel.”

He grumbles. “So what?”

You scramble to think of a satisfactory response. “S-so let’s get reacquainted in the shower, yeah? That way I can see your handsome face, at least.”

He chuckles, grazes his teeth “playfully” across your cheek. “Bossy thing.”

“You like it.”

And to your shock, he agrees with an amused huff. Hauls you up in his arms and walks you back to the still muggy bathroom. You’re set on your feet and spun around, chin jerked up to receive a savage kiss. All tongue and teeth, no finesse. He’s just licking into your mouth, hungry and animalistic, spit dribbling down your chin.

When he finally pulls away, you blink spots from your vision. Finally focus on his smug features and make a soft, horrified noise when you register the splatter of crimson across them.

“Och, that? My little bird had watchers.”

Of course you did. The horror ebbs a bit. Resentment has made you indiscriminately bitter.

“Oh,” you say, “th-thank you. Definitely glad we’re showering first, then.”

“Squeamish?”

You’d like to know when the world turned upside down and John fucking “Soap” MacTavish began teasing you about the blood on his face.

“A bit,” you admit.

“Poor dear,” he coos. “Hard to believe we were made for each other sometimes, aye? Complementary, we are.”

Is that what he thinks? Christ.

You turn to start the shower again, spine prickling with the weight of his eyes on your back. The water rushes down and then he’s crowding you against the cold wall beneath the (thankfully) warm spray.

“Y-you’re still dressed!” you protest between sharp nips to your collarbone.

“Fix it, then,” he snarls.

You claw his shirt up his back, get momentarily distracted by the impressive display of muscle hidden beneath. Draw your palms over his chest and feel him shudder.

“Fuckin’ heavenly, love,” he purrs. “Missed this.”

A vague memory comes back to you, him gripping you close because he felt you naked against him for the first time. Him admitting he hasn’t had affectionate touch in a while.

This… this you could work with.
