Re: High voltage cable/wire

It's not uncommon to see the control gear in older streetlights located in the base of the column, with the lamp on it's own at the top. I've certainly seen ignitors at the column base before. it's not that common now, but it was once the done thing. Wiring used to connect to the top of the fitting ...

Re: Narva Quits The Fluorescent Market

Currently I'm still ordering from Narva UK, but I'm now being supplied with Osram lamps by them (and Philips made Osrams if they're 6' tubes). Sad thing is, there won't be any sort of 'lamp' market soon, it'll all just be built-in, non-replaceable LED modules. I might quit the lighting game, not sur...

Re: SRS Ballast Capacitor?

Actually, just zoomed in your picture after typing that - if it's just that little cap in the picture that's gone, that's an RF suppression capacitor (not essential). Is there a larger metal or plastic sleeved cap in the circuit? This *could* be quickstart rather than SRS. Any chance we can see a pi...

Re: SRS Ballast Capacitor?

I'm afraid if that's an SRS fitting (which the 4 terminals on the ballast show that it is) the capacitor is essential. Wiring it out isn't an option on that circuit. I.m going to guess you need an 8.4mfd capacitor for that - what does it say on the label? I've not seen that rating of capacitor on sa...

Re: Replacement GEC Z8256 Bowls....

I know of 5 other collectors who own one, altho, all but one have decent bowls for theirs, so I'm starting to wonder if having some made is really an option :( Prohibitively expensive otherwise, as the vacuum formers seem to think that the mould alone will be close to £1K :(

Replacement GEC Z8256 Bowls.... I've approached a vacuum forming company with regards to having some bowls made up for the above lantern. The cost of tooling for this is NOT cheap, therefore, it's only likely to happen if enough people might be interested in one. If you might like one of these, plea...

Re: Short Time Running Of Fluorescents

Have to admit, I've wondered the same. I'm sure it won't do them too much harm (unlike old SOX / SLI lamps) but repeated switching versus occasional switching with long burning hours will slightly reduce the life of the tube. I can't see why never running it for more then 20-30 mins would be a probl...

Re: Questions: SRS instant start and tube banding

I tend to find that new tubes start instantly on SRS more often than not. As the tube ages, it then tends to adopt the classic SRS fade in over a few seconds. I have a 4' 40w SRS batten over my desk, this has a lovely old Ascot branded daylight tube in it and this always takes a few seconds to start...

Re: Narva Quits The Fluorescent Market

Something else that sprang to mind today, I believe Narva were the only manufacturer still making 'U' tubes (other than American ones of a different dimension). If anyone owns any fittings that use these, might be worth getting some spares in whilst you still can!

Narva Quits The Fluorescent Market

Apparently, Narva is 'restructuring' and will no longer be producing fluorescent lamps of any kind. A real blow, as I order mine direct from Narva and they're bloody good lamps. Apparently they're going to concentrate on the LED market - explains why they've really been pushing LED every time I've o...

Re: Who makes the best HF ballast?

Have to agree with Kev here, I rip tons of the bloody things out too. Generally find that quite a lot fail before the first tube has died - you replace the ballast and the same tube carries on working. I'm switch-start all the way, so long as you maintain them and don't leave failed lamps or starter...

Re: The Philips CorePro LED PLC Lamp

On a serious note, gotta be careful with some of these retro-fit LED lamps - I got a belt off a linear LED replacement tube once, the aluminium back section was at mains voltage! Shocking - literally! I'll always re-lamp fluorescent fittings with the power on, but I won't touch an LED retrofit lamp ...

Re: Superslim Lampholders

Well, boiling water works a treat! I can see why they were painted tho, rather than grey, they're a nasty, dirty brown they're so discoloured and stained. Need to try and get them back to the nice grey they should be now!

Just saved a single Superslim fitting from a church. Sadly it's been glossed, not a problem as far as the metalwork goes, I can strip that off and re-spray it, but someone has glossed the lampholders too. Anyone got any neat tricks for removing gloss from plastic lampholders without damaging them? C...

Ok, so, having no luck in finding a replacement bowl for a Thorn Beta 6 lantern (2x40w T12 lantern for 2' lamps) Have just been on the phone with the vacuum formers who could make one, but they're not interested in doing just a one-off. So, need to find a few other people who might also be after one...
