Magnetic or electric ballast?

[Hannahjc88]

Hi, please can anyone tell me if I have a magnetic ballast or electric? Bulb I have bought only works with magnetic.

Many thanks

Maybe replace the fitting completely

@Murdochcat why?

@Murdochcat why?

Because a modern LED, will be more energy efficient, give better light, and last much, much longer

@Harry Bloomfield I’ve put an LED bulb in and now far too bright for a bathroom. It’s a rented property but thank you for the info.

The old magnetic ballast will get warm, so there is some wasted energy, however the amount wasted is so low, not worth worrying about.

As far as I remember you can different rated led replacement lamps ( 6, 12 and 18W ) for those fittings. If it is too bright you probably just need the lower rated one.

Not quite as simple. Note when buying replacement 2D lamps, some have 2 pins and some have 4 pin..
IIRC the The 4 pin LED 2D lamps use the electronic control gear whereas the 2 pin LED 2D lamps, like yours, use a magnetic control ballast.
The ballast is matched to the lamp wattage. The tridonic ballast in the photo states the lamp wattage.

The best, and simplest option, is to simply replace the entire fitting, with one designed for and including LED's.

It shouldn't cause a problem putting a lower wattage than she is using sucessfully, would it
