Whenever you have time to thoroughly clean your home, you usually try to get the portions that are hidden from view. You check under the bed, vacuum beneath the cushions, or dust the tops of shelves—anything you can do to keep every part of your home sparkling, even if there’s no one around to see it. So why would you neglect to clean the ductwork?

So when customers ask us how many ‘Watts” do I need to replace an existing light source, we always convert them to lumens.

•  Pay special attention to the lumens per watt of a fixture. IT DOES MATTER. A LED product at 135 lumens/watt will consume far less energy than a LED product producing 97 lumens/watt. Not all LED solutions are the same. (remember, always buy on the lumens you need, never on the watts you think you need.).

•  To calculate lumens per watt, take the total number of lumens a product produces and divide it by the watts it consumes.

For indoor fixtures, figure on:

utility company. You can check if a product is DLC Qualified on the DesignLights Consortium website. DLC has rebates for Commercial LED Lighting and Industrial LED Lighting

•  Rebates with DLC Premium should be higher than rebates with DLC Standard. Your utility company is typically who provides the rebates and sets the rebate amounts.  Check their website.

•  All UL Listed or ETL Listed.

•  Replacing the light parts of an existing fixture with the a Retrofit unit will not void the UL/ETL Listing of the fixture. However, the exception to this rule are explosion proof rated fixtures (ie. Class I Div 2). Never retrofit a certified explosion proof fixture. UL1598C does not cover these types of retrofits.

•  ETL Listing is the same as UL Listing. They perform the same test, and the certification is the same. The only difference is that the company who performs the test.

Recently, the Obama administration adopted a new gas mileage standard for cars made in America — 54.5 mpg by 2030. That’s a big jump. The most recent figures — 2009 — show that average gas mileage for American cars manufactured in that year was 33 mpg.

Well, the new standard is good for reducing dependence on foreign oil and good for our pocket books — it’s supposed to save us $45 billion annually at the gas pumps. It’s probably also good for American competitiveness in export sales — people in other countries seem even more concerned about gas mileage than we have become. The 2009 cars we imported got 35 mpg, 2 miles better than American-made.

Most Americans support the idea of upping gas mileage. Consumer Reports found in a recent survey that 77% of Americans feel that Detroit should produce more fuel-efficient cars and the government should increase mileage standards. So, everything’s good….

BUT wouldn’t it be better to run our cars on ZERO gasoline? Wouldn’t it be better to go electric? I’m not talking about the government telling Detroit to manufacture only electric vehicles (EVs). But when we buy our next car, if we made it electric or hybrid, we would be asking Detroit to manufacture the kind of cars that emit zero pollution and don’t eat any Middle Eastern oil.

You might be thinking — yes, but where does the electricity come from? That’s a good point, but here’s the neat thing about electricity — it can come from clean sources. In Los Angeles, 40% of the electricity supplied by the Department of Water and Power is generated from coal — not clean. But that means that 60% is generated from cleaner sources like natural gas, hydropower, nuclear, geothermal, wind, and solar. DWP expects that by 2020, 0% will be generated from coal and 40% will be generated from renewables. Those are the facts about electricity in L.A. — and, I assure you, my being an electrician doesn’t give me any bias on the subject!

My next car will be an EV. In the meantime I’m lending my support to the cause by installing EV chargers for those in L.A. who are beating me to it and have already bought their electric cars.
