Has Westinghouse gone mercury-free with HPS?

Has Westinghouse gone mercury-free with HPS?

Click to view full size image

Here is a new Westinghouse 150w HPS lamp (chinese made of course), with the longer arctube than their previous 150w lamps. Whats also interesting is that these lamps appear to contain no mercury! Not only is there no evidence of a mercury discharge at run up, but these lamps run very yellow compared to standard mercury-filled HPS lamps. I tried to get a side by side comparison of the light color, but they both looked the same to the camera. But these lamps are definitely a different color, like a mustard yellow and not the typical orange. Also, there is no indication on the packaging that these lamps contain mercury. These medium screw lamps go in parking garage canopy lights.

I've see the HG free HPS lamps we have in Haifa, as golden yellowish orange color, and the regular and the super HPS lamp with mercury, as pinker orange.
Mercury free HPS lamps, have higher xenon pressure, longer and thinner arctube, than standard HPS lamps, and I think that they don't cycle on/off at EOL, but just stop working.
In their website , they don't list mercury free HPS lamps.

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 European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Westinghouse (well, ABCo really, they just use the Westinghouse name) doesn't make the lamps. The lamps come from multiple sources and they just slap their name on it. So it's possible some of the lamps are mercury free and other might not be. I would think the lamps wouldn't last as long with no mercury at all, but who knows, maybe that's the plan.

Look at the spectrum during run-up....if there are no Mercury lines, there is no Mercury, simple as that and proven beyond doubt!

I think streelight98 is absolutely correct as Westinghouse uses at least two chinese manufacturers for their metal halide lamps. In fact ide be willing to bet Westinghouse probably doesn't even know that some of their current HPS lamps are mercury-free, that particular lamp manufacturer likely just happened to come in at the lowest bid to make the lamps and that was it.
@globecollector Im still new to using a CD as a spectroscope, but after looking at some HPS discharges on here, then testing this lamp myself, I can confirm that the Hg lines are completely absent from this lamp when I checked with a CD.
@Dor123 yes, this lamp produces that golden yellow color you describe, not the usual orange

I will make a point to pick up other wattages of recently made Westinghouse HPS lamps and see if this is present in their entire HPS line. I normally don't use Westinghouse for relamping as they've become a more "residential homeowner" type brand rather than popular with commercial contractors like GE, Philips, or Sylvania has.

I'm actually looking for a mercury free HPS....the one I really want is the original Sylvania one made in Tienen in the mid 1980's...now long out of production....but any other sort is welcome too.

Yeah it's unfortunate that the Westinghouse brand, something that was known for superb quality, has become the trade name for a company that imports crapola from China.

Mercury free HPS lamps, are also made by the european Sylvania and Philips.
Mercury free HPS lamps, are more efficient than regular HPS lamps, because of the higher xenon pressure.

I assume this higher efficiency is at the cost of lower life? Or at a higher cost? (or both?) Or else they would have been the norm for all of these years.

This lamp has a 24,000h life according to the package, which is normal for standard HPS. Also, these lamps have a much slower run-up time than usual, in fact nearly double that of standard HPS lamps. Now the question is, what version is cheaper to produce? The standard mercury-containing, or mercury free? Because these lamps were slightly less expensive than other brand HPS lamps which is why they were chosen for this group relamping. Even the manager noticed the color difference in the parking garage after the new lamps were installed. "It looks more yellow".

Though, I wouldnt say these are any brighter or more efficient than standard HPS lamps, the output appears the same to the naked eye, but it is hard to tell given the color difference. Westinghouse didnt include the lumen rating on the packaging

I have a Philips mercury free 250w diffuse coated HPS lamp. It's made in Belgium and was made for the European market, but they are electrically compatible with ours. Yes it's much more yellow than a typical mercury filled HPS lamp.

May all the great lighting technologies have their place in history.

How much yellower? Like LPS yellow? Or like Sylvania HPS lamps? The GE HPS lamps we used to use here were a nice peachy orange color but the Sylvania ones we use now are a yucky golden yellow. I think the Philips lamps are like the Sylvania lamps. (In fact I think GE is the only one who's lamps are a nice peachy color).

More like a pale lemon yellow color. Yeah, similar to the Sylvanias you mentioned.

Oh my so like the yellow light on a traffic signal? Wow that's really yellow. Hows the CRI compared to regular HPS?

Traffic signal or bug-light yellow is a good way of putting it. Sylvania HPS lamps are less orange, but still not the color of this Westinghouse lamp. I cant say ive actually seen a mercury free HPS lamp operating until now. In fact the new color really took me by surprise. I personally dont like it, and thats coming from a guy who prefers HPS over mercury vapor. In fact, I would venture to guess that the CRI of these is actually worse than standard lamps, it certainly looks more monochromatic. I'll take the pinky-orange GE and Philips lamps over these any day, as thats the color I grew up with in the subdivision where I lived.

Mercury free HPS lamps, have 2100K and Ra8=18 compared to 2000K and Ra8=25 of standard HPS lamps.
Our LED traffic signal, have their yellow light looks exactly like that of LPS lamps. I don't remember what about our incandescent traffic lights, but they have an orange lens on the yellow light.

I don't think this one is mercury free. Hg-free HPS lamps also need an ignition wire alongside the arc tube due to the higher xenon gasfilling pressure, which this one lacks. Moreover the arc tube has to be made much thinner than this, and mercury-free lamps also require a much more expensive grade of ceramic for the arc tube as well as a more expensive material and process for the emitter coating of the electrodes. Nobody goes to this expense unless it's absolutely necessary. Since the modern Westinghouse is a company that simply goes shopping for cheap Chinese lamps that it can stamp its name onto, I would really be surprised if they would ever invest in sourcing products of superior quality or performance level!

Other than a spectroscope, is there any other accurate method of determining the presence of mercury? These lamps dont appear to produce any visible mercury lines on my crude CD spectroscope, but also the warmup and operating color is so bizarre that there is something clearly different going on inside these lamps. The color can be more likened to a yellow coated incandescent rather than the typical HPS color. And the warmup starts a pinkish white (like an argon discharge) then quickly becomes a low pressure sodium discharge color, which stays that way for nearly 5-6 minutes before reaching high-pressure state. That lemon yellow color only begins to show itself right near the end of warmup

Strange lamps for sure. They must've done something differently but kept the lamps the same price or cheaper.

Where is the listing for these lamps. I'd like to get a couple to experiment with.
