How to save electricity?

IIRC, LED is rated at least 20,000hrs..

CFL maybe 8,000hrs.. just a rough number..

btw, talking about lighting bills.... how you know the LED doesn't make a difference ar? you compare the before/after..?

Also, you need to consider the power rating too. If you replace a 22W CFL with 17W LED, (example only, pluck number from air), and it is same brightness, you will see a saving in bills.

If you replace a 22W CFL with 22W LED, you will not see any savings as they consume the same power. But the LED maybe brighter.

I did a rough calculation, very primitive though.

In my old home, the place is smaller and we used cfl bulbs. I only need 6 bulbs and 3 circular fluorescent tubes to lit the home during the night. The electricity charges is about $25. Now, with led bulbs, I need 8 bulbs, 2 circular florescent tubes and 2 linear florescent tubes for the place and the bill is about $35.

Technically the hot pot heats once and the rest of the time keeps warm. Er, I was just saying. Not that I need to make milk.

Correction. You do make milk and able to keep them warm too!

I am not even coherent. :slapshead:



Always get me into this kinda trouble. :torchme:

Back to LED - although they are known to last long, their performance in terms of brightness is not maintained throughout its lifespan.


I ever spoke to a supplier/manufacturer maybe 3 yrs back and based on their experience, they feel the savings one gets is not substantial vs a energy saving fluorescent lamp. But for commercial or industrial use, where other high power lamps are used, the returns are much better.
