I currently moved into a new house with several MR16 20W 12V Halogen spotlights installed. There are around 25 of such light bulbs around the house with 7 in the living room.
I will be using the lighting in the living room for prolonged period of time, at least 9-10 hours per day. I am worried that the running costs of the current lighting set up will prove expensive.
After looking online at various forums, I understand GU10 LED light bulbs are being suggested as an alternative?
In my previous home I had GLS LED 9W bulbs, and one light bulb per room was enough for me.
I would prefer to use those lights again in the new house, however there are no bayonet or screw attachment fittings in the house.
Since it is a rented home, I can not install completely new wiring systems without landlord's permission.
What would you suggest I should do? Are the MR16 light bulbs currently installed use up lot of electricity?
Thank you for your advice.
