I'm going to come along and I'm going to give you some fresh mitochondria.

Okay.

There's a group of us shuffling around corridors, all mumbling to one another saying, how big a stink is this?

And some people are... I reviewed a document that was sent to the European Commission last week just before I came over here from a very balanced Dutch lighting engineer when he wrote to the European Commission saying, we've got to rethink this.

And so...

The group of us that are shuffling around, some of them are saying this is an issue on the same level as asbestos.

This is a public health issue and it's big.

And I think it's one of the reasons why I'm really happy to come here and talk because it's time to talk.

Right.

We've got enough.

So, LEDs came in, and people won the Nobel Prize for this, very rightly at the time because they save a lot of energy.

They are very energy efficient because they do not produce on the whole light that we do not see.

So the effort is all in what we see.

Now, as you pointed out, the LED has got a big blue spike in it, although we tend not to see that.

And that is even true of warm LEDs.

And there is no red.

Remember, so we're talking about billions of years of evolution under broad spectrum sunlight.

When we had fires, that was pretty much the same.

A fire is pretty much broad spectrum.

Candles, pretty much broad spectrum.
