paper that we don't want to lose because of UV rays.
>> This is a little off track, but as you choose lighting systems, is there
evidence that maybe worker productivity gets better under certain conditions?
>> There's a lot of talk about that right now, John.
And when I went into our facility, La Plata Electric,
and we switched out all our lighting, I chose a 4,000 kelvin, a little bit whiter,
not quite to daylight but a little bit lighter.
Because that helps increase productivity because it affects the melatonin level,
and that effects circadian rhythm.
So, and a lot of people want real, real warm, but the fact is, for productivity,
for schools, and there has been studies done in schools that are whiter light
increase the productivity, keeps kids more alert.
So that's very important.
>> One of the things that is an issue and
the sustainable business class, is a climate change and CO2 emissions.
So when you go into a business, are people concerned about the environmental effects,
or are there other motivations, mostly, for changing out these lighting systems?
>> Okay, when I go in, I'm trying to help people save energy, all right?
By saving energy, they're going to save money, all right?
Then I bring in the maintenance factor also.
But the fact is, everybody also knows underlyingly or
in the end that it affects other things like LEDs last 10 times longer.
All right, when they last ten times longer, it means less in the landfills.
It means less glass, it means less recycling.
>> All right, less material to make them, I guess really.
>> Exactly, exactly.
We preach this all the time about the environmental
positive effects of using LEDs.
One ton of carbon dioxide can be kept out of the atmosphere
by using one only LED, that's huge.
So it really does make an environmental impact.
>> That is amazing, because an LED is small and
a ton of CO2 sounds big, so [LAUGH].
>> It is and again, you're looking at 22 years of burning sometime.
And the amount of bulbs that were going to be used in place to
that over the 22 years, and the amount of fuel,
sometimes fossil fuels that were going to run those 10 or
12 bulbs to replace that one LED.
>> We've talked about the A19 bulbs, screw in ones.
But in a lot of commercial retail environments,
it's these fluorescent bulbs, the four foot long fluorescence with balasts.
Do we have equivalents, the energy saving equivalents for those?
>> Yes there is, and those old fluorescent tubes use ballast and
the way you can do it in a commercial application,
especially, is to change the tube out and bypass the ballast.
So you're taking the ballast totally out of the equation.
Direct wire in the tube.
The other way you can do it is buy a whole new fixture.
Sometimes buying a fixture's a quality way to do it.
It looks great, it looks almost like you're remodeling.
>> What else do you see as sort of exciting areas in this whole
energy savings, particularly the lighting area?
>> Well, John, this is something that's not coming down the road, it's here.
But it's being used more and more, and that's the use of controls.
After you've put in the LED, you save 75% over the previous lighting.
Then what can you do to save more energy?
Let's put controls up, put occupancy sensors up,
vacancy sensors, motion detectors, daylight harvesting.
>> I want to go back to something you mentioned, your peak power.
So at night, lights go on, TVs go on, computers were streaming.
