Darfon off grid microinverter
This is a microinverter meant for direct driving 120V loads from a single PV module. My guess is that this is a prototype given the handwritten markings on the nameplate and that it is serial number 3. I can find no information on these other than a blurb in some Darfon promo literature.
Under low PV generation conditions, it drops its output potential to (in theory) reduce the load power, but this power reduction method only reliably works with resistive loads. It is also slow to bring it's output potential back up to the 120V to 130V it is supposed to be when the low sun condition ends.

36W and 101W street railway lamps
Просмотров 512 месяца назад
These are interesting lamps in that they are gas filled. most likely with nitrogen. These lamps used to be vacuum atmosphere. The reason for the vacuum or nitrogen fill is to prevent catastrophic arcing when the lamp burns out, as these lamps are meant for series burning on 600VDC traction circuits.

GE LUH150 penning start HPS mercury retrofit lamp
Просмотров 713 месяца назад
These are a special type of high pressure sodium lamp designed for use on HX/high leakage reactance and choke/reactor high pressure mercury ballasts. They use a penning mix neon/argon gas fill in the discharge tube which has a much lower starting potential than the xenon gas fill in regular HPS lamps, which eliminated the need for an ignitor. The tradeoff is that these lamps are about 15% to 25...
One Electrical linear halogen retrofit compact fluorescent lamp

This is meant to replace 3⅛in/78mm recessed single contact linear halogen lamps (standard size for up to 250W). It says 230V/50cy/sec on the lamp, but these lamps use ballasts which are frequency agnostic to anything in the range of 50cy/sec to 150cy/sec or so. It's also rated for only 9W and thus wouldn't be very bright at around 500lm and change. An exact luminous flux isn't given on the pack...

      The transformer is custom as it serves double duty as the lamp ballast and thus has a deliberately high series impedance, so you probably won't find a COTS replacement. You could use a generic bug zapper transformer and separate preheat choke ballast for the lamp.

    I have a bunch of Philips 56W 130V vacuum A21 street railway lamps that I bought at a surplus store. They are '90s vintage. They are very nice bulbs to use for general lighting as the lamp envelope stays cool due to the vacuum design and they last a long time. One feature of vacuum lamps is that they luminate (brighten) and nigresce (darken) more slowly than gas-filled lamps. I had them in a Victorian era chandelier and when you turned them on they would light up noticeably more slowly and extringuish slowly too.

    nice! I have been acquiring a stash of Arlen EFS electronic starters before they all vanish against the LED onslaught, I have got a few EFS120's and some EFS600's but the elusive EFS600UVX escapes me, I tried to order a couple that where showing as in stock from a specialist lighting wholesaler, but I sadly got messed about with incorrect substitutes, which is quite frustrating as I do have some US and European VHO tubes in my collection which I wish to start as gently as possible I am especially curious to know what sort of triac the EFS600UVX uses, the TN22 is only rated for 2A max, but im pretty sure the short circuit current of a 1.5A sun-bed choke may well exceed that... as an aside note on regular ol EFS600, I noticed there seems to be 2 distinct types, older sorts that are rated "30W-125W" and newer sorts rated "4W-125W" and what I noticed is the 30-125W always starts the tubes nice and cleanly, a solid preheat follow by a clean strike just like in your video but the more modern EFS600 4-125W sorts, seem to not strike the tube as cleanly, they preheat the tube for a few seconds, then while still preheating the tube, they also try to the strike the tube, so for about a second or so its stuck in this in between state with the ballast buzzing loudly as the triac pulse, before it finally allows the tube to strike I never liked how they do that, so I always look for the older 30W-125W ones, but I do wonder what the difference is between the 2 sorts to cause this differing behaviour?

    I’ve heard of those before. I believe I’ve seen a picture of a Sylvania one. Definitely a unique feature, but I don’t like how they implemented it. Even if you just wanted to turn the nightlight on, you have to turn on the CFL on first, which would encourage unnecessary starting of the CFL, wearing it down. Not sure if there would be a better way to implement the nightlight though. Are the LEDs daylight or warm white? I believe the Sylvania one I saw had daylight LEDs.

    I take offence to the statement garbage leds. Yes, the product was well designed, but also ĺed's can be. Poorly made,/cheaply, and designed led lighting product's coming from mainly one country in Asia have given them a bad name. One main fault in òut side high power lighting is that damp gets into the pcb, or to thin a barrier, shorts out the led heat sink to the aluminium heat disapation plane, also poor power supply/driving circuits, ovrdriving the led's and specifying the incorrect colour e.g. warm/cool or day light 3000/4000/6000, in most cases 6000 is best for outside and worknplace conditions. Also, as a rule of thumb, they save 90% energy used most of the power used in previous lighting is producing heat. If everyone in the world changed to led lighting power consumption, could be reduced, by 80 to 90%. I changed my lighting at home from nearly 2000 watts to 176 Watts if all lights were turned on. Thanks fir the video.

    • @randacnam7321

      Can LEDs be made good? Yes. Are there applications where they make sense? Yes. Problem is that they have a lot of poorly researched failure modes due to them being the _current thing that must be used everywhere._ A big reason for this failure risk is the root of a lot of efficiency gains in the past decade, which is the discovery that InGaN and GaN die efficiency goes way up at certain combinations of high operating temperature and high die current loading. This efficiency gain comes at the expense of die service life, which is why there are LED lamps available now with service lives of as little as 5,000hr. Then there are other problems with phosphor failure (the cause of all those LED streetlights turning blue/purple, which is a massive eyestrain hazard). There are even problems related to photodegradation of fixture components; the failure of ~20,000 Leotek LED streetlights in Detroit a few years ago was photodegradation and subsequent burning up of fixture lenses. And a big problem is that components can't be easily replaced, and if/when something fails the whole fixture is garbage. The "90% power reduction" claim assumes that the LEDs are replacing incandescent lamps with comparable rated service lives. When replacing 80lm/W or higher fluorescent/HPS/LPS/MH lamps, the gains aren't anywhere near as big and can even be a step down in efficiency (such as yellow LED anti turtle/bird fixtures being 50lm/W to 60lm/W vs. the 100lm/W to _200lm/W_ of LPS).

    nice fixture and lamp :) I seem to recall those split coil GE ballasts could be reconfigured for either 120V or 240V, by changing the jumpers and how the coils are wired, but I could be wrong there, but I seem to recall thats why they had the split coils (in the same way a 115V/230V switch on a lot old PC PSU's worked by configuring the 2 capacitors into a voltage doubler) another thing is in your description, you have it a bit backwards, H34 lamps are rated for no Less than 50F (10C), and are *explicitly* not rated for cold temperature use, some manufacturers even rate them for indoor use only, H36 lamps have no such limitations and since I am at it just for completeness sake H36 lamps run at 4A-4.2A 265V, this is also comparable to the British high voltage Mercury lamp specifications (which was the first spec of 1Kw merc in the UK, but the later introduced low voltage spec was always much more common, although its worth noting in the UK we had 2 specfications of high voltage lamp 265V 4A and 300V 3.3A depending on what your between phase voltage was exactly) H34 lamps run at 130V 8A, this makes them more or less compatible with the British/European low voltage specification of mercury lamp, and I actually have in my collection an *E40* Capped Westinghouse H34 1000W *orthophosphate* lamp that I found here in the UK, and looks quite weird seeing such a European style cap on such an American looking lamp :)

      Description updated/corrected. Many thanks. I've heard of those multiple primary 120V/240V ballasts, but this isn't one of them as far as I can tell.

    An interesting note about 1000W H36 mercury vapor ballasts is that they often have roughly the same OCV as 1000W M47 probe start metal halide ballasts as well. This means that you might be able to reliably run 1000W M47 probe start metal halide lamps on many 1000W H36 mercury vapor ballasts very reliably without any modifications to the ballast whatsoever. In GE’s catalog, they specify that regular 1000W M47 probe start metal halide lamps can reliably operate on 1000W H36 mercury vapor HX autotransformer ballasts and 1000W H36 mercury vapor series choke ballasts provided that they have a minimum OCV of at least 440V and they should start reliably on those ballasts provided that the temperature is above 0 degrees fahrenheit.

    Hey mine just failed. I don't have any voltage on the secondary side of the BCK2801 transformer. Is the transformer at fault or could a component connected to it be the cause? Thanks

      Something is up with the SMPS driver. Probably a dead driver IC, but those going can be due to other things as well as cause other things to die.

      @@stevesmith3033 That means the transformer drive FET isn't driving the transformer. You should see a ~600mV to 700mV diode drop from the source to the drain of this FET if you do a diode check _with the charger disconnected from mains._ The gate should read as an open to the source and the drain.

    I had a bunch of 56W Philips Street Railway vacuum lamps in service in a chandelier for over a decade and they had darkened a lot. But I love how vacuum lamps ramp up (luminesce) and darken (nigresce) slowly.

    Those are some very weird/unusual wattages for those light bulbs. I have *never* seen 33W or 405W. What were those intended to be used for?

    • @randacnam7321
      @randacnam7321 8 месяцев назад

      33W lamps are/were commonly used for signs. 405W lamps are/were for lumen rated incandescent street lighting, where the lamp power is dictated by the design luminous flux and design life. They were available in everything from a 32W 200lm lamp all the way to a 860W 15,000lm lamp. Both of these were designed for 3,000hr. The longer a lamp's design life, the higher its operating power. The 2,500lm lamp class (one of the most common sizes) would use 175W, 189W, 202W or 205W depending on if it was designed for 1,500hr, 3,000hr, 6,000hr or 12,000hr respectively. The 405W lamp in the video has a 3,000hr design life and has an equivalent 448W 6,000hr lamp.

    Actually, there is another legitimate use case for them: using British/European/Australian high-powered small appliances (mostly for kitchen and power tools) in North America. Normally, a 240V source for medium loads is supplied by a NEMA 6-15 or 6-20 receptacle. However, there are no travel adaptors with a NEMA 6-15 or 6-20 plug and a universal receptacle output. With the Hydrofarm BAOX receptacle, one can use a 3kW British/European/Australian hot water kettle in North America at full power for practically instant heating of water, by simply first plugging in a NEMA 5-15 to universal travel adapter that is rated 13 A or higher. IMPORTANT: Just put a label stating "240 V" on the exterior so one doesn't accidentally plug a 120 V appliance into it.

      Those 240v travel adapters with NEMA 6-15 plugs do exist actually. They are just hard to find and often of dubious origin/quality. A better solution is to get proper receptacles that mate with the plugs of whatever appliances you want to use and make adapter cords or power strips.

      @@randacnam7321 Never mind, I found then online. I searched for NEMA 6-15 universal plug adapter instead of NEMA 6-15 travel adapter and they appeared in the results. As expected, travellers rarely plug into a NEMA 6-15R or 6-20R, which is why the keyword of "travel" does not appear in the product description. I can see that some of them with NEMA 6-20P are only rated for 10 A, which is stupid given that the standard NEMA 6-20R also accepts NEMA 6-15P, just like the ubiquitous 5-20R accepting the standard 5-15P.
