Such confined, limited spectrum of light.

Never experienced it before.

And one of the other issues that relates particularly to devices that people may use to increase the amount of long wavelength light.

Some of these devices are lasers.

No living entity has ever seen monochromatic light before.

It is a totally alien thing to life.

No, do not.

First of all, I think the majority of them do no harm.

I suspect that the majority of them have a positive impact.

But we've opened up a lot of those devices and they're pretty poor.

Poor in terms of the amount of energy?

Poor in terms of how they're put together, first of all, the value of the components.

Got it.

When you get an LED, an LED is like buying a car.

You can buy a bad car or you can buy a very good car.

A lot of the LEDs are not what they say they are.

Certainly when it comes to things like 670 nanometers, which is popular, they're hard to get.

So they're not what they say they are.

And very often they're not what they say they are a year down the road when they've been on and off for a long period of time.

Not in North America.
