It’s a while since I bought light bulbs and visiting Mitre 10 on Saturday was a bit. Um. Mind boggling. It was really helpful to have the large signs above each type of light explaining the relationship in lumens and watts.
I now have in my house:
Eco classic bulb in the loo
LED in the hallway (extremely bright)
old style eco in the dining room and bedside table
old school classic in the living room and bedroom
It took a good while to sort old school wattage, new school lumens and assorted other measurements. It’s a bit confusing that incandescent bulbs and LEDs are measured in wattage.
Post purchase I found this useful.
I’m trying to conduct an experiment but have forgotten which is where. I expect I need a more scientific approach.
