$150 for a 575 HMI par?

I brought a few similar fixtures and they were not hot re-strike. It would be nice to know if the lamp is (HR) hot re-strike. The lamp cost more than the fixture.

Resurrection. https://www.usedlighting.com/29014/elation-opti-par-575-g-plus on sale for $75. I see a couple of issues with this unit though. 1. That ballast definitely would need to be extended just to be able to mount the light. 2. Power Supply: 230V/50Hz May not be problems at all depending on you guys with electrical prowess think. On the site there is a pro version with a "split ballast" using a powercon connector http://www.elationlighting.eu/en/opti-par-575-pro-g-plus.html. That price is super cheap

Funny, usedlighting's site has been down for a few days now.
 
As for me although I have (4) Arri 1.2k's and a few other HMI's . Since the 1st wave of Elation and Chroma Q par 575"s, that were posted here. I now have a total of (5). I've used them to throw light down a street and lit the backyards of houses that I've shot in music videos. I must say for the cheap cost, including buying bulbs and a few barndooors they held up well so far.
If I were a person that had no HMI's I would certainly pick up one of these.
 
Also, if I remember correctly the 1st two fixtures I brought came with barn doors, a used bulb and a set of lens at $150.00. The only thing I did was change the plug the at the end of the power cord.
 
These very low-cost types are likely to be cold-strike and magnetic ballast, so they'll have flicker problems when shooting off speed (and 24fps is off speed, unless you start playing with shutter angles, and even that can be a bit of a chore).

The problem is that there really isn't an easy way to a 575W electronic ballast. Possibly a 600W type intended for, er, "hydroponics" could be used (many of these actually contain HPS mag ballasts marked 600W anyway), but there can be problems with HF ballasts causing squirrely arcs and flicker, and if you want hot restrike it's a much bigger deal - you may as well just buy the Chinese HMI PARs from ebay at that point.

I am slightly confused as to why Used Lighting is suggesting what's clearly a hot-start G22 lamp for them. Perhaps I'm wrong, in which case 75 bucks for a hot start 575 is deal of the millennium.

Not completely discouraging, just wanted to air all the issues.

Damn at 75 bucks its tempting to pick up 2 to go with the one I bought a while back, but these do seem like they would be a pain to mount on a light stand (would need some heavy duty stands) and for someone who is not a electrician geek what would i have to do to change the plug so it plus into a regular house outlet? Only bumber I've had with the one light I have is the sound the fan makes but for the price I can't complain.
 
Sorry to resurrect an old thread but I have looked everywhere and I can't seem to find any HMI lamps with UV protection and GX9.5 base, does anybody know where I can find some? All I can find with G9.5 base is 400W lamps, the only UV Blocking 575W lamps I can find have G22 bases. Reason being is because I am pretty sure the S4 Lenses do not have any UV protection.
 
Some do, some don't, and there is no easy way to tell which is which. This is a problem to the extent that one manufacture I spoke to about this exact issue admitted they'd had an issue with a bad batch of lenses, resulting in a few people getting some nasty sunburn at a car show - and that was with the lights mounted far overhead. This is not a theoretical problem, and it's easy to imagine that film and TV applications, with the lighting much more in direct view, might risk more severe injuries.

I have not seen an equivalent to Osram's UVS-suffix HMI in GX9.5, but I'm slightly surprised they haven't done it. They must ship a hell of a lot more of those than the G22 variant.

Not sure what to suggest. Recently someone had a bunch of G22 hot start PARs up on eBay for a song, no lamps or lenses. I'd have had the lot except they were in Canada and the shipping and import duty was murder. They would have permitted the use of UVS G22 lamps.

Thanks Phil Rhodes. I actually took everything you said earlier about UV radiation very seriously and didn't think you were being overly cautious at all. In fact I want to thank you for giving out all that information because if it wasn't for you I might have placed this light behind my subject, pointing straight at me and the camera lens for some flare effects, not realizing it would be burning my retinas off! Definitely going to have to go the G22 route. It's not worth the risk otherwise.
 
And also thanks for mentioning the Osram UVS-suffix, I could only find Koto-branded UV blocking bulbs prior, and Osram's are probably better right? Aren't they the ones that invented HMI technology in the first place, or branded it?
 
I believe so. Essentially identical technology is called GEMI, CID, CSI and Brite Arc by other people. I don't know about Osram being specifically better. The underlying physics are pretty consistent. Mercury and iodine are... well, mercury and iodine. MSD and MSR can vary a bit, so, naturally, peruse the data sheets.

What you're looking for is a "chroma-q daylight PAR." They're rare, but there's some white ones, reportedly working and with lamps and lenses, here in Toronto for $265. These were actually made in the UK to begin with, to my chagrin, and are now being sold off by the exhibition people worldwide. They're particularly desirable because they are hot-start and G22-based, although I suspect (I don't know) that they might be a bit buzzy, like an HMI stuck in "flicker free" mode. Non-movie ballasts tend not to bother with the more complex sine wave drive mode for sync sound work as it isn't necessary for the thing to be so acoustically silent.
