How to save electricity?
-
5 of us. DH, me n 3 kids aged bet 7 to 12.
-
we have this space which is lit by four florescent tubes. These four tubes are controlled by one switch, so when I on the switch, all four will light up.
Wta - if I remove two of the tubes and on the light, does it affect the consumption of electricity? because two tubes are removed, will consumption be lower? -
of coz. Definitely.

Hi Limlim, are you responding to my qn?
If it is seriously going to reduce consumption, then I will go ahead to remove some tubes. And oh I got it wrong, there are 8tubes (instead of 4). -
Not sure if there’s energy saving florescent. At home we change ALL bulbs to energy saving bulbs, yes it does make A LOT of difference in the electrical bill.

Hi Lynn, are you referring to my qn?
I am not just looking at saving electricity consumption in this case. It's simply TOO bright. Imagine a space that can fit a king size bed, with 8 florescent tubes! Can you imagine how bright it is?
So we thought of removing some of them to cut the brightness but we wondered about the electricity consumption... -

Almost All \"Energy Saving bulbs\" are florescent type, as compared to incandescence ones.
or the same power consumption, F type convert approx 80% to light and 20% to heat, whereas C (filament) type convert 80% to heat (wasted) and 20% to light.
Hence, to achieve the same brightness, one can get a F lamp with lower power consumption and hence lower bills.
That is why it is frequently advertised as energy saving bulb.
And the bulb has got twisted Florescent tubes in it. -
Oh, by the way, if your place is air-con…
By generating less heat, your air con no need to “work so hard”, and that could explain for the “huge” savings… not just bills relating to lighting alone. If fact, if you replace with F bulbs of similar wattage, there would be no saving in lamp bills at all… just brighter illumination. -
florescent tubes used to be more energy efficient than bulbs
then came the energy saving bulbs (made from twsited / spiral florescent tubes)
now the “in” thing is LED lighting which is truly energy saving - and more durable than the flourescent tubes
