I remember in Sizewell 'B' finding a 58 watt fluorescent can use nearly double if capacitor missing and voltage a little high. This is not a problem with electronic ballasts, before the electronic ballasts you could get optimises which were auto stepping auto transformers as a small over voltage can mean a large increase in power used.
However with electronic ballast there is very little between LED and fluorescent, LED seem to be better the bigger they are, but range from around 60 to 110 lumens per watt, with a 5 foot tube around 100 lumen per watt, and a fluorescent is around 90 lumen per watt, so very little in it.
The problem is the replacement LED for 5 foot fittings is around ½ the output of the fluorescent. Also direction is a problem, I remember having a fluorescent work lamp, light was 360º so very good, but the LED tube is directional. This can work both ways. but the simple bulb with connections at the top very little spread of light as all from a small area, but with connections at bottom and light reflected off the ceiling the spread is far better.
So in general when going LED it is not a like for like, one has to look are where you want the light, and in domestic also look right. So my living room has a single ceiling rose, now has a chandelier with 8 SES bulbs, but not central so there is a dark area of the room, no real access to ceiling void to add a second ceiling lamp, so I have fitted LED lighting strip to the Ikea Billy Bookcase display cabinets smart so in the main run low output so just lights up items behind the glass doors, but I can turn them to white and up the output to 58 watt, that's 2 x 18 watt and 1 x 22 watt, this then makes up for lack of light that end of the room, but I can select how much light depending on what we are doing.
The problem prior the 'Smart' lamps was going around switching on or off lamps, but with 'Smart' easy a simple hey google turn off living room lights turns them all off. I do same with outside lights, one command turns them all off. Think my wife is loosing use of her fingers.
It seems the whole concept of lighting has been turned on its head, but as to
I've noticed now that turning on both flicks the smart meter monitor up from green to amber.
I am becoming a slave to the SCARTA display showing what I am using, dashing down stairs to put the dryer on before the batteries are full so we don't export power. Not got a smart meter so don't know what it shows, but I look at the five figures, solar, grid, use, battery charge/discharge and charge level, and I am becoming a slave to the display. We have the machines loaded ready to run, and switch them on when we have excess. May be it will wear off? But solar panels have changed our whole life style.
