CCT indicates the hue and tone of white light emitted from a specific bulb or fixture. It’s measured in Kelvins (K), which is similar to degrees in Celsius. Different temperatures on the Kelvin scale represent different colors. For example, light at 2000K-3500K looks more orange/yellow and is called ultra warm or warm white, and as temperature increases in Kelvins, color changes to more of a “paper white” known as natural or neutral white (between 3500K and 5100K) and finally into a bluish-white known as cool white (5100K+).

As a light source’s color temperature increases, brightness often increases. While shopping for LED lights, pay close attention to the color temperatures that are available for any one bulb or fixture. Choosing a warm white bulb with a color temperature around 3000K might mean sacrificing some brightness. Whereas, if you choose the natural white version, it’s likely that it will have a higher output.

In order to understand nanometers, you must first understand the electromagnetic spectrum and wavelengths. The electromagnetic spectrum is the entire range of invisible and visible light, and a wavelength is the distance between peaks of light waves. Wavelengths are measured in nanometers, which are simply units of length that indicate colors of light within the spectrum. Nanometers will tell you how red, green, yellow, purple, etc. a light source really is. These measurements start lower at ultraviolet and increase from green to blue, yellow, orange, and then red. The wavelength of a colored light can be found in the light’s specifications table.

Fixtures or bulbs that emit wide beams, such as BR LED bulbs for can lights are great for areas that require a lot of light, such as basements, kitchens, or living rooms. Narrow beam angles like those from can lights with MR LED bulbs are best for highlighting decor or small areas. Globe bulbs, such as G30 LED vanity bulbs, have 360-degree beam angles, which means that they throw light in all directions. Globe bulbs are the perfect choice for centralized light fixtures.

As a DC or Maryland resident, electricity and natural gas are deregulated, giving you the option to choose your energy suppliers. Virginia residents can choose their natural gas supplier, but electricity is not deregulated in the state.

Deregulation occurred back in 1999 when the Electricity Competition Act passed with the hopes of introducing competition for Pepco, the primary electricity provider in DC. Nearly 170 companies are now licensed as alternative energy suppliers in DC.

In theory, increasing competition is a great plan. It allows you to comparison shop and choose the best alternative energy supplier based on rates, customer service, and other factors.

Unfortunately, this also sets the stage for unscrupulous alternative energy suppliers to pitch low rates by phone, direct mail, and door-to-door salesmen—only to charge more than the customer was originally paying. Learning how to spot these phony propositions can help you choose a legitimate alternative energy supplier!

Hundreds of DC residents make complaints about alternative energy suppliers every year. According to a recent Washington Post article, Starion Energy is one such company that’s had its fair share of complaints in recent years. The article reports that in some cases, the switch to Starion has caused customers’ electricity bills to increase by more than 50 percent—despite having agreed to make the change for money-saving purposes.

Since alternative energy suppliers are prohibited from “engaging in…unlawful, misleading or deceptive” marketing tactics under District law, customer complaints are taken very seriously. If you have had a bad experience with an alternative energy supplier, file a complaint with the DC Office of the People’s Counsel.

Despite the bad press a handful of alternative energy suppliers have received, there are plenty of legitimate electricity suppliers in the DC area:

Even with shady suppliers ruled out, you still have dozens of legitimate options. Narrow down your selection by:

Prisons and correctional facilities are full of security threats, it’s just common sense.

That is why it’s a major task and a seemingly forever ongoing one to try everything in the book to reduce threats and increase security for everyone in, near, or even outside the facility.

Today we wanted to address how we can solve 2 major correctional lighting system and things you should look out for when finding fixtures perfect for your building and budget.

Firstly, a LED prison lighting system will reduce indirect stress and irritability in both inmates and staff.

Secondly, LEDs within correctional buildings will improve detection of movement, which we all know is crucial.

How you ask? Well, lets talk about each one individually and break it down a bit more than just one sentence. From there, we will talk about how to go about making the conversion over to LED, like we mentioned at the start.

Have you ever been around a light that was flickering and or buzzing? It can get annoying, and fast. Imagine living under these conditions, everyday all day; no break other than a few hours when you go outside. Sounds like no fun, and it can lead to some serious stress and irritability issues for both inmates and staff.

For obvious reasons, additional stress on inmates will never produce a good outcome for anyone. But, another important point is that this can effect your staff and guards too. It can affect their ability to perform at full capacity, which in combination with highly irritable inmates is not a good mix whatsoever.

With LED technology, they will never be susceptible to flickering nor buzzing. Not even near the end of the lights lifespan will they flicker or buzz, unlike other technologies commonly still used in such facilities. Thus, you can avoid any stress or irritability which may be caused from flickering / buzzing lights.

If you can’t tell where everyone is at every second, you’ve got an issue. This is especially important for outdoors during the time when it is dark out. Sure, some light is better than none; but why jeopardize your operations with a flickering light when you could upgrade to LED and get rid of the issue entirely?

As you may or may not know, flickering lights make it harder to not only detect movement, but also identify humans. Think of a strobe light, it’s a bit harder to actually make out what is going on entirely. This holds true with a flickering light, even if it isn’t as bad as a strobe light is.

Here we are going to list a couple of the other major general benefits that LED technology offers over other technologies such as metal halide, HPS, fluorescent, and similar.

There are really only two routes you can take, LED retrofit lighting kit will work perfectly. On top of that, retrofitting is a much cheaper option (typically) then a full replacement is. So, if you don’t need to fully replace then stick with retrofit kit LEDs and you will save a lot on your lighting system investment.

Conclusion

Flaws can always be picked at, especially in such tedious and unpredictable environments like the one we are discussing in this topic.
