One of the most unique light paintings I’ve seen, this image has a fluidity that causes the brain to confuse light for matter. It is neato. What makes it neato? Well, I think it’s mostly neato because the way the lines are painted makes the light seem like it has taken form and is alive.

3. Sphere of the Open Water

I do not understand how some light painters are able to create such perfect perforated light beams. But I like it. Light painting is able to create such perplexing images. How is one to feel about the image of a lonely self-circling disc of multi colored light? It’s a little sad. But also a lot of fun. That’s weird. And maybe that’s the particular weirdness of light paintings.

5. Or, Then Again, Maybe This Is the Particular Weirdness of Light Paintings

At least, that’s what my two-year-old would call this photo. What a great idea to take a long exposure of a car and to keep it underexposed, knowing that the brightness of the light “paintbrush” would balance out the composition. I chose this example because it emblematizes the way light painting adds imagination to reality.

7. The Whole Light Paint Bucket

First of all, if you don’t get the title’s reference, then don’t worry about it. It’s a video game thing. Second of all, if you have any kind of interest in photography but spend a lot of time working indoors, you’ve probably tried taking pictures of inanimate things around your office. (OK, so I’m talking about myself.) Chances are, you haven’t had much luck. The pics were probably more fun to take than to examine, and they have probably been long since lost in the black matter of erased data. In other words, the photos weren’t good. But this one happens to be really awesome. It’s fun and very cool looking. Hadukin! Hadukin to bad office still lifes! Hadukin to darkness! Ha. Du. Kin.

The search for commercial lighting systems can be confusing, misleading, and overwhelming at times. With all of the different terms, labels, and technologies being used how can anyone expect you to make any decisions with all of that going on?

Well, this post is going to at least relieve your confusion about DesignLights Consortium vs EnergyStar approved and qualified lighting products. There is a difference, and you need to be well aware of what it is when you are looking into a new lighting system for commercial Click here to read it, then come back to finish the rest (opens in a new window)!

The major difference between DLC and EnergyStar is that DLC is only for commercial lighting products while EnergyStar is more focused on residential purposes and applications, with a minor hint of commercial lighting in there as well. This makes DLC the more “go to” organization when it comes to commercial lighting qualifications as they are seen as the experts on commercial lighting products and technologies.

Anyways, when it comes to becoming EnergyStar qualified for a lighting product, a product needs to pass these (along with others) guidelines to be able to be EnergyStar qualified:

Conclusion

After this quick, simple, and brief overview of the differences between EnergyStar and DLC; we hope you’ve found some light on the topic (get it, light).

In a general sense, most of your commercial lighting purchases will include DLC qualified products, especially when buying for warehouses, factories, parking lots, street lights, and the like all except for those listed.

Solar Farm

From science fiction to massive solar plants in the American West, solar energy has fascinated and tantalized scientists and writers for generations.  The promise of easily-accessible, virtually free energy from the large fusion reactor at the center of our solar system (the sun) is enticing and we’re getting closer to harnessing its power effectively every day.

Solar power is interesting because it’s one of the few electrical energy systems that does not use a turbine to generate energy.  Photoelectric cells contain a material that releases electrons when hit by a photon, generating electrical power.  There are no moving parts, no fuel to burn and pay for, and only occasional maintenance to keep the system performing optimally.

So what is holding back the proliferation of solar energy?  Space and storage.  We can generate large quantities of energy from solar, but we do not, at present, have the right method to store that energy for periods without sunlight (night time and storms).  So far the best response has been homeowners installing solar cells on their own homes with battery storage systems linked into their own neighborhoods.  By splitting up generation and storage within the neighborhood itself, enough solar cells can be installed to generate energy both day and night.

Space is at a premium when it comes to energy generation.  Solar power plants take up more space than traditional plants, while generating less energy per square foot.  Because solar cells need to be placed over large areas to maximize sunlight, installing power plants in urban areas can be difficult.  Though installing solar cells on your home can be done simply.

We mentioned self-starting or “œblack-start” energy systems.  These systems can be started without power applied to the system, a huge benefit to fuel-fed power plants, and necessary in the event of major blackouts and power losses.  True, we can supplement with gas turbines or nearby power generation, but we also want black-start renewables.  Fortunately, hydroelectric power plants require no off-system power to function.

Hydroelectric plants are special because, while they also have a somewhat variable energy source, they also have one of the best energy storage systems available: potential energy.  Hydroelectric dams use flowing water to spin turbines, typically generated from lakes and rivers.  Rather than storing generated electricity, hydroelectric plants can store water at a higher altitude.  By storing water in special tanks, they have access to electrical generation potential by simply releasing the stored water and allowing it to spin the turbine.  Hydroelectric power is perfect for energy storage, but they’re limited to specific areas.

When it comes to home repair and renovations, many people attempt to handle their home improvement on their own when it should be left to the experts. Due to the abundance of television shows depicting do-it-yourself couples attempting to renovate old properties and the consistent bombardment of commercials from big box home improvement stores, fixing anything around your Des Moines home seems like something you should be able to handle yourself. Whether you are a seasoned handyman who has been handling home repairs on your own for years or an inexperienced homeowner working the kinks out of your first home, there are a number of tasks that absolutely must be left to the professionals because errors and mistakes could lead to severe injuries that could even prove to be fatal. Many of these scenarios require the work of a residential electrician, and a common one is electrical trenching.

Electrical trenching is the excavation of your property to prepare for electrical installation, and it could end in tragedy if you do not call an expert. While digging a ditch does not seem like something that would require a residential electrician, it is especially necessary when handling electrical issues. A residential electrician will not only be experienced in handling the electrical trenching, but they are also aware of the safety precautions. Under your lawn, various utility lines are running ranging from water to gas to electric. And if you were to damage one of these services, not only would you be at fault, but you would also be placing yourself in grave danger.

Do not start digging up your yard without first consulting an expert residential electrician. When you need electrical trenching in Des Moines, call the Electrical Guru’s at 515-446-7040 so we can safely and professionally handle the electrical trenching for your home.
