The Aurora MR16 50W Square Halogen Bulbs have a clear white light colour with a colour temperature of 2800K and a 60 degrees beam angle. These dimmable dichroic bulbs have a wattage of 50W and a brightness of 680 lumens. The bulbs have a 2-pin connector type, a square shape, and a GU5.3 socket, suitable for various lighting fixtures. With an energy efficiency rating of B and a bulb life of 3000 hours, these halogen bulbs are a reliable choice for illuminating your space.
These lamps are no longer being made and all the light fittings in our flat use them so I'm always looking out for them.
It was unusual to see a large batch of new ones become available.
This is a good replacement for the Aurora which appears to be no longer available. We have the square fittings all over the house and use these bulbs on a regular basis.
They work well and are good value for the money.
