Sylvania 69/108W SPX Eco Arc HPS Retrofit Lamp

Sylvania 69/108W SPX Eco Arc HPS Retrofit Lamp

Click to view full size image

Here is a Sylvania SPX Eco Arc high pressure sodium lamp which is designed as a retrofit lamp for either 80W or 125W mercury vapour fittings. It has a specially designed arc tube which operates at a higher voltage than standard HPS lamps and vapourises all the mercury and virtually all of the sodium when running. It has a glowbottle starter so it can operate directly on a mercury ballast without the need for an ignitor.

Can anyone assist with dating, please..? The code is 10 which could be either October 2001 or 2011.

Number 10 = October 2011, if there is Dash under the number it would be October 2016, however, they could also be October 2001, or with Dash October 2006, as they first came out in 2001. also manufactured too was the SHX 110W, I have a few SHX110 Basic Retrofit HPS Lamps from March 2018 see HERE

Thanks Colin. Do you know if/when they stopped making them..? No dash under the number by the way.

I think they were banned in 2015 when MBF lamps were.

Sounds about right. So could be 2001 or 2011. Hopefully James will know.

Hi Sadly back in 2015: Phase out of plug-in/retrofit High Pressure Sodium Lamps. (Direct replacement for HPMV Lamps). Plug-in lamps must correspond to Super/Plus High Pressure Sodium Lamps almost all plug-in/retrofit lamps will be banned. To be honest I dont understand why they are Banned as they give a lot more Light than the Mercury Vapour Lamp, (20 to 48% more Light), Fortunately CP Lighting still have them for sale but are £26.21 GBP including Tax, for the 69/108w Lamps.

As you lamp has No Dash, your lamp was made in the First Half of the Decade that would be October 2001 or 2011.

Yes I got this one from CP Lighting, they only had 2 left when I got this one last week. It was very slightly cheaper (£25.82) via Amazon though. Big savings..!

They were banned because they're not LED, of course. Or am I being cynical..?

Its ridiculous, they ban the MBF lamps then ban the energy saving retrofits for them

Yep everything which lights up in the UK and Europe are nothing but LED now, thanks to the EU. fortunately you can still get these Lamps either directly from CP lighting or from Amazon UK, but once the stock runs out, that will be it.

Is there a big difference in brightness depending on the used ballast or is this lamp designed in such a way that the difference in light output is minimalised?

I have a dual 80/125W ballast and I fitted a changeover switch so I can select either rating easily. There is definitely a difference in brightness, but I don't have the necessary equipment to be able to accurately measure it.

Have you see this lamp glowing mercury colour during run-up without passing SOX color at all? This is unique to unsaturated HPS lamps such as this one.

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.

I don't remember, I'll do a warm-up video sometime.

these Lamps when first lit emit a cool white light like a Mercury Lamp, then goes amberish light, before they change again in to the familiar Golden Yellow Light of High Pressure Sodium Lamp.

So this lamp is desinged to run on BOTH 80W as well as 125W MV gear? How does that work so well as it's quite a difference?

Yes, it's quite an interesting design. James has a detailed description of it here although I believe that his lamp is an engineering sample, hence the clear bulb.
