Correct, but my (limited, I admit) tests agree with the original assumption that LCDs consume much less power. As does every other test I have heard on the matter... still waiting for your source.

You may be able to get an energy meter for free

The proposed model has 2 parts with a wireless display looks similar to the one Tim_B found.


What does anyone think of this energy saving gadget ?

Nigel Goodwin

My only source was the sets I tested at work a couple of years ago, I would like to do some more on the newer LCD sets (no new CRT's to test any more!) - but my true RMS meter doesn't work on AC any more

It's pointless trying a meter that's not true RMS - I did tests with a scope a few months back, the current drawn from the mains isn't anything like a sinewave!.

well I was previosly asked to state what the manufacturers say now you want me to measure it again. PEOPLE GROW UP. as for modern TV they still use 35 W for a 15" screen so forget it. I think they should have outlawed the CRT by now even if only for its weight and carrying cost and don't call me nuts because there was one bright spark that decided a solar panel takes more to make than it produces in it's life time, I am astounded at the IGNORANCE and stupidity of many members here we are after all supposed to have a technical background of some sorts yet many seem to cling to such stupid myths

You really shouldn't tell people to grow up and then call everyone ignorant. You should at least follow your own advice.

Everyone here does have somewhat of a technical background, or at least wants to. None of us know everything, and many (most) of us think we know more than we really do (including myself at times). So just calm down and let everyone talk peacefully. You have no enemies here and nothing to prove, just lots to learn. BTW, I am directing this towards everyone, not just Thunderchild.

Fred.Amoson

I'm interested on people's opinions/theories on that device also. I would think if it did what it says, everyone would have one.

Nigel Goodwin

Most of them are a scam, and usually just a crude power correction device.

well I may not have 100 % technical proof that LCD uses less than CRT as I don't have AC amp meters etc. they are not easy to find here in Italy and I don't have a lot of need for them and so don't want to spend the money but I have been able to prove that LCD is more efficient than CRT perhaps I cannot make a definit percentage rekoning all i know is there is a big energy saving my basic measurements have been able to at least determine that yet I have still being practically called a liar and people have convincing said that CRT uses less than LCD well what more can I say. if somebody would like to send me the equipment i will carry out acurate measurements and let you know.....

No one has made anything like such an assertion! - get a grip!.

You just made a blanket claim that ALL LCD uses less current than ALL CRT sets - yet you've then said that you've no way of measuring it, and certainly have never compared more than a VERY tiny sample.

All I've said is that this isn't always true, SOME CRT sets use less current than SOME LCD's, and the converse is true in some cases as well.

well as you didn't want to consider different measuring methods as comparable no I don't have a 100 % acurate method. but if i test a CRT on a refurbished electric board meter and it reads 100 w and then measure the DC amperage usage of a LCD that reads 1.4 A with 12 v supply so something like 18 W cmon you got to admit to a difference, I might not be able to say ok 100/18 = the efficiency difference but give me credit there is a huge difference there no mistake. oh and the CRT had a random image a general mixture of colour so don't come and say ooh it must have been all white.

and
That was my thought too. I can't see how any gadget like this can work especially with such thin wires, unless it corrects the PF on CFLs in which case it's a chocolate teapot.
