My understanding of the "don't touch quartz halogen lamps with bare hands" issue is that any oil deposited on the surface from the skin will burn, and the resulting remnants/soot becomes blackened carbon that absorbs more heat which creates hotspots on the surface when the lamp is burning. I though it was those hotspots/uneven temperatures that lead to premature failure.

Besides burnt residues, skin oils are soluble in hot quartz. These skin oils dissolving in the quartz cause to to devitrify which craters its transmissivity and thus it overheats and causes envelope failure.

Totally dig this video..

Actually, the LEDs are the only ones you can accurately call a light. The rest produce far more heat than light. They are heaters that can also light a room. LEDs produce mostly light. Some do generate a lot of heat but that's usually due to an inefficient circuit design and not the diodes themselves. They have to convert 110ac to around 3dc. A quick and dirty way to do that is to burn the extra energy off as heat. That's why some have heat sinks. It's a sure sign of a poorly made bulb.

I have seen 12 volt bulbs with an e26 base before mainly in fairgrounds and it really stumped me for a bit. Also fun fact an incandescent filament isn't just a coil, it's a coil that's been coiled up. The coil you notice first is actually made out of a coil of wire to begin with.

Interesting on the halogen explanation, my dad always told me it was the oils on your skin getting on the bulb would create a hot spot on the glass and cause the bulb to break and fail

@Rico702Vegas

That is actually true. I've done it where the glass/quartz actually pops off in the exact location I touched it. The oils on your skin "weaken the bulb" because of the temperature difference created by said oil, etc. To say that touching it makes the glass more porous is a bit far fetched. It's glass, super hard. He even started that particular glass is extra hard. How is oil going to penetrate glass? Or make it more porous? Lots of food companies would have to re-think the wheel.

You remind me so much of myself when trying to explain things. Greatly appreciated. By the way. On the high pressure sodiums the arc tube is actually made from alumina because sodium doesnt react with it like it would with glass where it will eat through it and begin to leak. Older ones will because they now use a tiny resivour at the ends to hold sodium when its cool or hasnt evaporated all of it. And it is basically spots where it pools up in a dip around the electrodes. And the incandescents are actually pretty common and are one of the only lamps/bulbs that have almost perfect balance spectrum of light of 100cri so they are used where color rendering and color quality is most important over energy usage.

I think it's the other way around, high power bulbs have a thick filament and burn hotter for the same life. A small fridge bulb of 10w has a thin uncoiled wire stretched out in several lines and really wobbly. 12V halogens have a thick filament last very long with an inductive power supply. 30W on 230V installed horizonally stretches the filament under its own weight. CFLs operate at too high power (20w, yours says 42w) that rises up into the small ballast if installed base up. Worse than LEDs. Metal halide is one of the best lamps with close to continuous white light. I remember mercury street lamps producing a weird blue light that seemed bright, but it was not possible to read under it or see grey LCD screens. They looked nice in winter with snow.

Use of polycrystalline alumina in high pressure sodium lamps is due to liquid sodium and sodium plasma being _very_ corrosive to quartz. Also, the plasma in a HPS lamp is too cool to excite the mercury which contributes little to no light of its own. It's job is as a buffer gas to drive up plasma resistivity and thus allow for shorter arc tubes. Mercury free HPS lamps exist, and they have much longer arc tubes to correct for the lower sodium plasma impedance.

if the fixture of a hps light came with a 175 watt bulb can it be replaced with a 70 watt hps bulb so it is not so bright?

@loudspeakertestsmorebyaida3804

Жыл бұрын

No, it’s only rated for a 175 watt HID bulb. You can’t downgrade a high wattage high pressure sodium bulb or any other HID bulb with a lower wattage bulb like you can with an incandescent, halogen, CFL, or LED fixture. Also, that’s either a 175 watt metal halide or 175 watt mercury vapor fixture, so it can only take either a 175 watt metal halide bulb or a 175 watt mercury vapor bulb. I don’t think 175 watt high pressure sodium bulbs exist at all. Installing a 70 watt high pressure sodium bulb in a 175 watt fixture is not a good idea at all. The ballast is more than twice the wattage of a 70 watt bulb. It will create more heat, wattage, current, etc. than what the bulb is rated for, which will shorten the lifespan of the bulb. It will cause it to cycle on and off like any HID lamp when they reach the end of their lifespan, it could potentially explode, and it could potentially cause a fire. I advise you purchase a 70 watt high pressure sodium fixture if you want a more subtle light output. If you know how HID fixtures work, then you can retrofit the fixture with a 70 watt high pressure sodium ballast. Look at the wiring schematics online if you’re willing to retrofit your existing high wattage components with lower wattage ones. There’s still high pressure sodium retrofit kits available online, even though they’re slowly being phased out in favor of LEDs.

only rapid start tubes. The fixture also requires a dimming ballast and compatible dimmer. The setup keeps the cathodes properly heated while varying the arc current. A standard fluorescent ballast used with an ordinary dimmer cannot be dimmed, if you try it may dim a very small amount then drop out, since the cathodes would also receive less heating current and be unable to maintain an arc.
