Excessive??? Compact fluorescents failing.

[The Ghost]

I just wonder if the circuit the HF gear is on is mixed with old starter in another area. The two types do not get on well. Apparently transient voltages are not liked by HF. Is there any other gear around the (office/unit/warehouse???) that may cause a similar effect?

I dunno darkward, laughter eases the savage breast. Its just how far one takes it.

Yes it may but we have forum sections and open threads for such banter, my gripe is derailing someone else's thread and staff having to remove 12 posts that have nothing to do with what the OP posted and especially when he still online at the time replying and trying to answer questions put to him.

No Vort, the whole place was refitted five years ago.

A mix of these TL5Cs and, T5s and some rare as hens teeth Phillips PL-R compact fluorescents. But importantly all HF.

It’s really only the TL5Cs that are failing.

Can someone delete these distracting posts that are explaining why distracting posts are distracting. ;-)

As an aside why have a twin lamp fitting fed using a single HF ballast, one lamp fails the whole fitting is down.

Ok might sound silly or too easy but the TL5C is rated for 22-42w they aren't putting in the 17w lamps maybe, no couldn't be.

Ha, no not that stupid. They’re the 40W flavour TL5Cs.

Well I say that but the ones I’ve been replacing with are 40W, went of the label rather than the old lamp. Can’t say I checked what the duds were. Now they’re in a coffin at the wholesalers.

Number three on my to do list, check all existing lamps are correct.

Keep these coming I might stretch this out till Friday. :-0

Thing is, in real life we have a laugh & a joke, whilst working, discussing serious issues, even when we are feeling low. We don't just wait for the proper moment, or limit it to special occasions . Its all part of life's rich tapestry.

Even the OP's enjoys the banter. Hope I'm still here tomorrow, in the literal sense.

soz. thought you said bantam.

Well, not a very productive day.

All voltages 235-240 and stable as far as I can tell without long term monitoring. Checked every Click distribution box and at one fitting per box, with the lights on.

Did not see a PIR switch whilst there and apparently someone else had set them all to 30 mins which looks ok.

All lamps correct, of the random twenty I checked .

Did find three old fluorescents in the ceiling void that were on. These have been unplugged from the Click boxes.

This does not appear to be a deterioration issue as the maintenance records show a pretty steady rate of failure from installation.

The ballasts are Tridonic so not crap only question left is whether they are compatible with the TL5CS, which I have to call the manufacturer tomorrow.

Hopefully there’s a picture attached showing the ballast.
