CDO TT on Cosmo Ballasts

[Mrstreetlight]

A friend in street lighting was telling me his boss won't buy cosmo lamps anymore since they cost him £90 a lamp, he rather convert the lamp holders to E27 / E40 and use CDO TT on the original cosmo ballast.

I wonder how long these CDO TT lamps will last on Cosmo gear and if anyone has seen this done anywhere else?

Sorry, HOW MUCH for a Cosmo lamp... That's insane. Still, I spose it's all part of the drive to push you towards LED.

It will work, as in they will light up but nor the ballast or lamp will be happy!

[Mrstreetlight]

It is ironic though how CDO is still cheaper on the other hand.

I checked online and the average of CPO is between £70 to £90, only ebay is cheaper which most contractors probably won't buy from.

Cosmo has really had a short life.

Davy was telling me the other day there is some PFI scheme and they are down for bulk chances they couldn’t get Philips on the bulk change so they got truehalo China crap and at night none of them came on lol they flashed started to warm up and then went off and stayed off.

I heard about this as well lol.

I want to try test a truehalo on CDO gear to see if it fairs instead

The only good thing you can say about cosmo is that the lifespan is phenomenal, I put some secondhand Evolos up in 2017 with used lamps from Davy and stoner and almost 10 years on no failures they are on part night also at home never had one fail

This ia really good going. Which ballast are these running?

Honestly, I think you would come better with LED conversion.

I think however there were some CosmoPolis compatible lamps with standard screw base, however I will need to check that with my Philips document at some point later that week.

I generally agree that the Cosmo Lamps were a short thing. However tehy lasted about 15-20 years as if i recall correctly they were launched 2007 ish???

When I look here there were some shorter lifed philips street lighting lamps. City of Leipzig installed 210 and 315W CDM-TW (I think) fittings and when the first relamping come the 210W was alredy discontinued by Philips. The 315W was as well but thatone was cloned by China for the growing of green leafy substance.... So they used these instead.

Yeh I agree I think most of the time the fittings were bulk changed after 6 years the lamps would not probably gone on longer. Interesting to see how the ones I have installed in various places will last
