client has about 24 1200 x 600 recessed fittings in suspended ceiling ( shop ). problem is 6 are not working. it's not the tubes, there are no starters, so it's got to be the ballast units. ordered from local supplier 3 weeks ago. today they say they can't get them. each fitting has only one...
i fitted 4 5'twin corrosion proof T8 with electronic ballast
3 of them are giving trouble -sometimes they start
other times not -or might go off after a few minutes
i assume there's a fault with ballast-i doubt it's voltage but will check
anyone had similar issues thanks
Hi All,
A friend has just mentioned that when they turn their living room light off (a class 1 fitting with 3x 60w lamps controlled by a 1 gang, 1 way switch switch) the flourescent light in the kitchen goes off for about 5 seconds too then comes back on. Its controlled by a 1 gang, 1way...
Had a look at a job earlier which is to replace 9 6ft twin fluorescent fittings in a small warehouse.
At the moment there is nearly 20 single 5 ft fittings, all fed from 1 32 amp MCB:eek: and on 3 switches. All cabling is in 1.5mm t+e believe it or not:rolleyes: run on some cable ladder that...
fitted 4 'alaska' brand 5ft twin corrosion proof w/magnetic ballast and T8 tubes last week
supplied by CEF
everyone of them seemed to be faulty-take off the cover or give them a tap and they'd come back on
eventually i put it down to the end caps-voltage was ok and i don't think it was the...
Hi,
generally speaking if a afluorescent light isn't working is there any quick way of narrowing down the problem between the starter, the tube and the ballast/choke. Apart from changing starters and tubes (and i can't carry the latter around on the off-chance) is there a way of testing each...

But when I have re-energised the circuits there is a group of fluorescent lights not working.
Thay are just glowing at either end...

Hi all I fitted 3 5FT fluorecent fittings in a garage, I removed 3 batten fitting so it was a straight swap, problem is when customer switches on the lights the RCD in the house trips. Should these lights go on the non RCD side
Hi all,
I'm in the process of rewiring my flat and due to the 25% rule have bought a few fluorescents.
Do I need to use switches rated at 6AX or 10AX with these or will any crabtree, MK etc lightswitch from screwfix do? I am aware that dimmers don't work with all fluorescents but bog...

Had a customer ask me to replace 2x 8ft Fluorescent fittings in his Garage. Picked them up from the Wholesalers, but received a call from the customer stating that the 8ft Lamps are discontinued (or phasing out). If this is right, (I've found some mention on Google) can the 8ft lamps be replaced...
Hi All,
I am about to instal 100x30w fluorescent lights and was wondering if there are any rules that I have to apply in terms of switching these lights as I am concerned about having so many lights switched off one switch.
I also have been asked to install the lights using gear tray that...

As these lights don't usually have a loop terminal.
What is your prefered method of looping a couple of garage fluorescents each with a single switch controlling them?

Hi, can anybody help me. In a communal block of flats the communal areas lighting consists of 12" long strips, 3 of theses strips were not working when the button was pushed. However, when the strips were removed and replaced they illuminated, then when the switch eventually turns off and then...
Am I right in thinking that when fitting fluorescent lights instead of using a ceiling rose to make the connections as it would be exposed do you use a 4-way junction box instead?
Ment to ask in my course but forgot.
Thanks in advance

hi all, I have asked this before but still not sure, when calculating v.d on fluorescent/discharge circuits do you include the 1.8 factor in the calc or is this just for cable current rating
e.g is it like motors where you are allowed a bigger vd on startup, but size the cable on the rating...
Alright, got my AM2 tomorrow and when reading through some notes they say for I.R testing fluorescent fittings to remove the electronic starter. Wasn't sure if they were referring to the sarter or the ballast. Normally when I test a circuit with one on I just disconnect the switch wire.
So can...
