The most common misconceptions that lighting I've seen here among LG members: 1. In some of my pictures of HPS lanterns being dim or that looks like underdriven, some American members commented that the capacitor is defect: Well, this can only be happen with CWA ballasts that requires the capacitor for lamp operation. which are of course non-exists in our streetlights, since we are 230-240V, 50hz. through American style arena floodlights and some highmast lanterns, actually contains CWA ballasts, either imported or local made. Some American people things that CWA is the only HID ballast available in the US. I've seen this happens also with fluorescent lamp field. 2. Funkybulb's said about people that saying that the power factor affects lamp operation. Seen this a lot here between American LG members. 3. Calling fluorescent lamps "Neon" (נאון): Was a very common misconception in Israel. 4. Calling Automotive MH lamps "Xenon" (Even between lighting expert): In LG, this looks to me that this highly false misconception is much more common in America than outside America, as if this was actually began in North America and spread from there to the world (In Israel, its looks to me that this misconception is copied from America). As xenon discharge is inefficient at 35lm/w and automotive MH lamps are available in a wide varity of colors (Compared to xenon which have only one white shade). And of course, the common misconception that people and the media said about CFLs and LEDs. Update: 9.5.2021 Ah, and calling incandescent lamp with neodymium glass or a fluorescent lamp with 5000K and Ra8=95 "Full spectrum", which is a common highly false misconception between American people, as there is no such a thing "Full spectrum lamp".

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the international date format (dd.mm.yyyy).

I lives in Israel, which is a 220-240V, 50hz country.

Another misconception about lighting that I easily see is when European people commonly assume that same wattage metal halide lamps are interchangeable on the same ballasts and I sometimes see some European members connecting probe start metal halide lamps to superimposed ignitors. The fact that all same wattage metal halide lamps are interchangeable on the same ballasts is actually wrong. In Europe, there are 2 breeds of metal halide lamps: some metal halide lamps are designed for operation on high pressure sodium ballasts while other metal halide lamps are designed for operation on mercury vapor ballasts. Operating metal halide lamps designed for mercury vapor ballasts on high pressure sodium ballasts significantly overdrives them and shortens their lives while operating metal halide lamps designed for operation on high pressure sodium ballasts on mercury vapor ballasts increases the likelihood of the ballast overheating due to the lower arc voltage of high pressure sodium lamps. Lastly, operating probe start metal halide lamps with superimposed ignitors will lead to the destruction of the starting probe and render the lamp usesless.

Quote from: Rommie on December 20, 2020, 02:41:02 PM That's entirely possible, I never said otherwise; the specifications of that device may well allow it, even though it was designed for a 220-240V supply. But others may well not work, so making blanket statements such as "European SOX ignitors all require 240V" doesn't help.   This topic is nearing end of life, I  think. I'm not going to lock it (yet) but let's keep things on track please, and not get bogged down with ambiguous statements or all we'll end up doing is going round in circles, which doesn't help anybody. To clear things up, the misconception involves people thinking that the ignitors and fluorescent starters marked “220-240v” will NOT work on any ballast that requires a LINE VOLTAGE other than 220-240v, which includes autotransformer ballasts with an input voltage of 120v, but an OCV between 220-240v. The truth is is that these ignitors and fluorescent starters will STILL WORK on autotransformer ballasts with an OCV between 220-240v regardless of the line voltage anyway, but if the ballast is a simple choke ballast, then the line voltage has to be between 220-240v.

Does anyone know about common misconceptions that North American members have about European lighting and common misconceptions that European members have about North American lighting?

This topic is all about discussing general misconceptions about lighting. My next question is about what North American LG members often mistakenly assume about lighting in Europe and what European LG members often mistakenly assume about lighting in North America. The reason as to why I wanted to post that question about across the pond misconceptions here is because I do not want to have to start a new topic that is related to an older topic such as the one here.

That is true. To me, it seems like members from certain continents like Asia, Africa, and Latin America are heavily underrepresented here because most of the LG members I see live in North America, Europe, and Australia. In addition, I seem to understand that most countries in the world in general use European market lighting.
