Odd Lights

Please don't ever give anybody any advice about anything on this forum again.

BAS despite your good intent; I hope you do not mean that literally, one can only try their best in life.

You have some of the most bizarre ideas about electricity I've ever encountered.

12v across 4 3v bulbs was not the best example and was one of my dumber moments on here!, 12v / 4 bulbs = 3v per bulb of course, but my point was about voltage being higher at the beginning of a series chain than at the end relative to the active direction of current.

In the real world, I more than know that CFL would not work in series. Was just eliminating one of the reasons not responsible for different brightness's.

Utter nonsense.

I think I should ignore my distant memories from primary school; traditional series wired Christmas lights are not dimmer in the middle and thus I have just contradicted myself BIGTIME!

Traditional ring lights (the brand "ring") get dimmer due to voltage drop over a long distant.

Why did I use memories from when I was 6 and not ohms law and common sense to tell me the obvious, After all LED's in series are the same brightness!

Maybe I should head for the stage exit after all!

Relative to some voltage reference point (like the other end of the 'chain'), that's true - but it is irrelevant. What matters is the voltage across each bulb. Since they are in series, the same current flows through all of them and, if they are all identical (same resistance/impedance), that means that every one will have the same voltage across it - as Mr Ohm's Law tells us, the voltage across one of the lamps is equal to the current flowing through it multiplied by its resistance.

As BAS has implied, you really need to try to get to grips with some basic electrical principles before you can really start saying things about electrical installations. As he has said, some of the things you have written today are totally bizarre, and certainly not correct!

Kind Regards, John

Not going to disagree with you at all, made myself look like a stupid fool. I should resist from posting more offten, after all my skills are as a web developer and not an electrician.

At least I know that Insulators are good Conductors.
