it can work but it is not stable either the ballast or the bulb itself can reduce its life these electronic ballasts have fuses so if something goes wrong the ballast can turn off the bulb because i did an experiment i tried a 150w HPS bulb with an electronic ballast ie philips dynavision prog xt CPO 140w worked for a while but after 46 seconds the ballast cut power to the lamp! On the other hand, a CDO ballast will work just fine with an HPS lamp because the cdo and son ballasts have exactly the same specifications! The supply current of the lamp is: 0.39-0.29A, voltage range Un: 208-277v, Uout 250v and required voltage to start the lamp at 3.3 kv, that is 3300 volts and operation as a CDO 70 lamp is at 91 -96V and the SON 70W lamp works at 90-92volt so there is no difference between CDO and SON very little difference in the operating voltage of these lamps so it will work fine, I have ballast cdo 70w specifically the philips dynavision prog xt cdo70 and it works perfectly with 70W HPS Lamp without any problems! but CPO bulbs actually work very differently than a CDO or HPS bulb or whatever
I love the way lanterns get re-lamped where u live. I’m just after saying goodbye to a Simplex Gemini on my road that only needed a relamp, but now it’s been replaced with an Axia 2 😭
I literally watched the bucket truck go down my road, as I was aware of the faulty lantern and what was going to happen to it. I sprinted out my front door just to see the bucket truck going past the installation and into a building site, so I ran back up to my house… but it was only turning in the entrance and I went back up later and this Urbis Axia 2.1 thing is staring at me with an ugly backlight cover on it *sigh*
I know. And the sad truth is is that that’s the only thing around where I live nowadays:( but you can get worse… after speaking to the lad that’s in charge of street lighting where I live, he’s changing the “default” lantern to the Urbis Izylum!! it’s even worse imo😭
Hi there I hope you know that you shouldn't handle these lamps with bare hands as the oils from your skin will create white stain marks on the quartz glass that can't be removed once the lamp has been used and has not been cleaned of the oils with methylated spirit Regards philips lighting engineer
but unfortunately cpo can't reach and compete with HPS, HPS is better at many things and a unique advantage that no gas discharge and high intensity bulbs have is really excellent brightness retention even at the end of its life it will lose 8 -20% brightness unlike CPO which will lose a little more around 20-30%!
CPO now losing a bit with modern CMH lamps, typically CDO-TT or HCI-TT from new serie have higher efficiency than HPS lamps from wattage label 50-100W, 150W CMH also can have a bit higher light output than 150W HPS from PiA serie
this development is practically useless, they have the same performance as a HPS lamp but at a lower power but 250 or 400 or 600 or 1000w can't have the same performance, there is nothing more efficient than HPS at 400w except LEDs but again very difficult , few LEDs in these WATTs to have higher lumens/watts, but all this is pointless since they are now replacing them all with LEDs! So these bulbs are useless, HPS was the most successful, and these CPO, CDO, CDM, MH even MV bulbs are more dangerous than HPS bulbs in case of explosion, the glass will break with great force, but it happens rarely, but not impossible, HPS lamps are practically impossible to burst because the pressure is not that high unlike metal halide lamps and ceramic metal halide lamps where the pressure exceeds 5 bar !! 5bar is very dangerous, as Philips themselves warn about these lamps, an HPS lamp is practically extremely rare to explode and maybe only at the end of its life, if this happens with an HPS only the arc tube or only the outer glass it will explode!
They are not high output, they have the same output, a hci 150w lamp gives 17,500 lumens and a philips master son-t pia plus 150w gives 17,800 lumens, so they have the same output
@@HIDSON-TPIA ik, MV never have tend to exploding, only arc tube blackening by time and normally it won't starting when all emitter from electrodes gone
The Iridium² looks very sleek in my opinion. Probably my favourite of the Iridium range (although i also like the gen1 and gen4)
one of the few street lights with electronic ballast! this philips dynavision prog xt cpo60 ballast could probably work well with a 70W HPS bulb
CPO lamps have totally different electrical parameters than conventional similarly wattage MH/HPS lamps

@@JonathanMillar-k8l ah that's unfortunate. the axia 2 doesn't look very good...

The Axia 1 isn’t great but it was probably the best looking one in the range - have you seen the Axia 3 EVO yet? 🤮
I absolutely hate those paint peels. They should go with powder coating. I bet that antenna is used to control brightness from the control room.
