Sodium light cutting out and do you like Sodium lights?

Hi,

Just had an extension and have a new sodium floodlight in the garden. Have noticed when we run the new shower which is 10kw it makes the light cut out.

Obviously these things don't just flick back on light a normal bulb as they cool down before coming back on so the shower may be causing a blip in the voltage.

Does this sound possible and if so should this issue be resolved by the electrician?

Thanks

Yes it'll be due to voltage drop extinguishing the arc in the lamp, however the slight blip usually shouldn't cause this. Check the fitting, if the ballast has tappings there's a chance it could be set for 240v and you may be one of the rare ones on a 230v supply. Is the lamp within the fitting brand new and the correct type e.g. if the fitting has an external ignitor the lamps should not have one internally? Also is it the correct wattage and type of lamp? SON lamps don't always work in metal halide fittings etc.

Can’t think of anything worse than a nasty orange sodium light in the garden, but each to their own.

Just glad I’m not your neighbour.

Thanks for your opinion on sodium lights.

Have updated the title to make your post relevant :D

Thank you for replying and apologies for the delay getting back to you.

Yes the bulb is new and the correct type and wattage for the unit. 70w.

I have another bulb so will try that.

We are on 240v here.

It isn't the end of the world and gives the neighbours a break while we shower haha
 
Check the ballast in the fitting, theres likely a terminal for a lower voltage setting

No worries. I would still double check the actual ballast as it could be for metal halide lamps only which run at different current & voltage to sodium lamps

I always thought for a 70 watt lamp they were the same 1 Amp Ballast
 
Not 100% sure but I have seen 70w ballasts that say only HQI (metal halide) on them.
