Are you really too thick to read ROI in context as Return On Investment?

Well, yes, he *is* thick, but he's also a troll.

There's no doubt about the former assessment and, despite his own
protestations against the latter charge, the effect of his readyness
to argue 'black is white' in the face of seemingly wilful ignorance
makes his behaviour indistinguishable from that of the classic usenet
troll.

I only bother to respond to his posts now to prevent any of his ill
informed assertions going unchallenged (in this case 'that LEDs are
ten times more efficient than incandescent lamps').

That's not ill informed, it's from first hand experience, with LEDs I
have on in this room right now.


Right, as we are talking specifics here, "ten times more efficient"
Could you enlighten us as to how you are measuring this?

10x less electricity, same brightness of bulb.



At the risk of repeating myself, knowing how much one has to be accurate
in these types of discussion. "How are you measuring this?"

Presumably you are measuring power consumed and light output. How?
