High bay lighting

[Spark plug]

At work I've been tasked with trying to repair a fault with the high bay lights.

The problem is some go on and off all day, but some go on and off in pairs or threes. I can't understand what would cause 3 lights to go off at the exact same time.

Any ideas?

Sounds like ignitors or lamps to me we had a car park with sodium fittings not so long ago and they would rotate one would go off next one would strike and so on! Could just be coincidence there all together! Could be voltage if it's low and they are trying to strike together. Sy

They could be wired on the same circuit, unique to them, although I sometimes think the fluorescent tubes in my workshop talk to one another and gang up on me.

What percentage of lamps are causing problems?, it may be time to suggest an upgrade to CFL or LED.

At a guess I would say 10-15% but I haven't counted yet. also the building is only about 5 years old so I wouldn't imagine the circuits have been tampered with too mutch.

for a start i would take a few bulbs out the ones that are working and swap them with the ones that arent and put the bulbs u took out and try em in the ones that did work . that will eliminate faulty bulbs .if there fitted with igniters buy a new one and try it in the dodgy ones . test with a meter for full voltage when there off theres only the ballasts left and there easy to test power in power out

I haven't got a cherry picker on site at the minute so I'm trying to come up with a plan of attack for when I get one.

Are they Mercury Vapour lamps? Have the same issue with out side floodlights when the lamps get old.

No they are high pressure sodium.

when u replace them make sure u fit the right bulbs they will have a triangle on them with either an I or an E STAMPED ON, I have internal igniters in the bulb .E have external igniters in the fitting not the bulb

I would be suggesting that as well. The sparkys have been into the place I sub to, replacing most of the High bays with LED.

You have to see to believe the difference. Not cheap (£130@)

there not realy tried and tested , there fitted with small fans to keep them cool , time will tell. probably be ok if they have a 3 year guarrantee

These don't have fans in them, at least I didn't see one, and the sparky didn't say they have them inside.

I saw led high bays fitted in a new build factory, they are excellent, I was surprised at how hot they got but not as how as sodium.

Any idea on the energy dateing figures?

If you're not happy with LED's, fit CFL's, we replaced all our old HP sodiums with Megaman Clusterlite

They fitted four in a sound cabinet I built to house wood moulder. It was as though the roof have been removed on a bright sunny day. Not bright or glairy. Amazing
