There was a time when buying light bulbs used to be a much easier task than it is today. Then along came LED, CFL, and light bulbs bent on reducing energy. With this, the good old incandescent started losing their place on our bulb holders. Gone are the days when finding a bulb for your home just meant looking at the wattage on the box. If a bulb was rated 100 watts, you knew it would be 25% brighter than a 75-watt one.

An entirely new rating system is now used and this has been giving shoppers grief for quite a while. At the center of this confusion is the word ‘lumens,’ which appears along its older and more familiar cousin ‘watts.’ Learning about lumens is the price you pay to help keep our planet safe. Don’t worry, though. We will tell you everything you need to know about the new lights rating system.

Lumens are units used to measure how much light a bulb puts out. Watts measure how much electrical power the bulb uses. With incandescent bulbs, the expected brightness pretty much depended on the wattage of the bulb. One lumen is equal to the amount of light given out by a birthday candle.

The idea with energy saver bulbs is to use fewer watts and produce more power. Incandescent bulbs produced by different companies are pretty uniform. On the other hand, energy saver bulbs are so varied, you don’t know if two 50 watt bulbs will be equally bright. This is why CFL and LED bulbs have lumen figures printed on them while incandescent varieties only have wattage.

When you hear “lumen per watt”, think miles per gallon. This is a measure of efficiency. It measures how many lumens of electricity a bulb can produce when using up one watt of electricity. This is the factor that should interest you the most when you are buying light bulbs. The first step is to figure out the brightness you want in lumens. If you want a brighter room, go for a bulb with more lumens. To dim it down, consider a bulb with a smaller lumen rating. Also, find the lumens per watt rating to determine which bulb has the greatest efficiency. Usually, the lumens per watt rating is an average, as bulbs reduce in efficiency with time. The lumen per watt rating is calculated by dividing the brightness in lumens a bulb offers by the number of watts it takes to produce.

Watts can be converted into lumens by multiplying the lumens per watt rating by the brightness.

The Federal Trade Commission now requires a product information summary, called the Lighting Facts label, to be attached to every lighting product. Another label that you should be on the lookout for is the Energy Star mark. The system was created by the Environmental Protection Authority in 1992 to govern the energy consumption of various household and industrial appliances. When it comes to lighting, this mark is put on bulbs that have met a certain lumen per watts threshold. This mark effectively spells impending doom for incandescent bulbs because they do not come anywhere near fulfilling these new efficiency ratings. If you are not into reading the fine prints and making calculations, the Energy Star logo will make your life easier. Look for the label on light bulbs to ensure you are getting a good deal.

The chart below can help to understand the Energy Star system.

This chart is an excellent indicator of how incandescents measure up to energy savers.

Aside from the fact that you have one more bullet in your trivia arsenal, your hunt for light bulbs should now return to the simple task it should be.

Any building, in any industry, in any area of the world, is susceptible to having potentially hazardous and radioactive exit signs installed throughout their building.

This could mean they are in schools, near your office, or anywhere else where a radioactive setting probably isn’t a desired situation to be in.

This is why we thought it was necessary to create this post to help and guide you towards identifying, removing, and finally replacing your radioactive exit signs with new signs that are much safer and even efficient, saving you money over other alternatives.

Firstly before we can remove and replace these seemingly nuclear exit signs, you have to be able to identify if you have them or not. But before that, lets explain what exactly makes these exit signs radioactive.

How are some exit signs radioactive?

Just the same way as some exit signs are safe, it is all in the way they are built. For some reason, whether it be technology of the time or something else, people assumed it was a good idea to create exit signs with Tritium, also known as 3H or H-3. Tritium is a radioactive isotope of hydrogen, causing exit signs made with this to be radioactive by default. The only seemingly positive upside to these exit signs is that they are non-electrical, meaning they won’t rack up anything in electricity bills.

But before you become alarmed with what we have shared with you so far, tritium emits only a low-energy beta radiation, which in turn causes the sealed glass tube it is in to glow (causing the exit sign to give off the illumination it requires). Thankfully, it is rather well known that this type of radiation can hardly (if at all) penetrate a piece of paper or clothing. So while yes it is a very low level (energy wise) type of radiation, the fact that there are alternatives that will remove radiation entirely from your building is all the reason to uninstall your tritium exit signs and replace them with something more safe, like LED exit signs.

Now that you understand the technology and how tritium in exit signs work a little bit more, let’s go over how exactly you can identify whether or not you have these types of exit signs in your building.

Identifying a radioactive exit sign should be fairly easy. All of these signs are required to have some sort of “Caution of Radioactive Material” warning on the fixture.

If you do find such a warning label, it is safe to say your light is made of tritium. Another tell-tale sign is whether or not your signs are connected to an electrical source or not as tritium signs do not require any such connection.

Once you’ve identified if you have a tritium exit sign or not, if you do happen to have one, you may continue on to removing and replacing it with the alternative exit sign, LED.

As with any lighting fixture, we recommend to bring in a professional contractor to do the job. But as a general guideline, you can typically recycle your tritium signs by returning them to the manufacturer or place of purchase.

If you purchased the building with them pre-installed and are unsure of where they came from after inspection of the signs for any brand markings, you can try two things:

1: Try contacting the previous building owner or collect records of where they were manufactured

2: Recycle them with a third party. like these), buying them, then installing them yourself or with a professional (we recommend a professional).

Here are a few things you should remember and keep in mind when dealing with a building that has radioactive exit signs:

Great outdoor lighting provides your home entryway with a welcoming and luxuriant presentation, ensuring just the right level of illumination for the safety and security of visitors and guests. 

Now is the time to assess your property and invest in a custom outdoor lighting design to increase your home’s curb appeal and provide a luminous finish to your home entrance.

New innovations include outdoor post lamps, decorative lanterns and energy-efficient pathway lighting.

To make your nighttime outdoor environment as comfortable, safe, and maintenance-free as possible, great lighting is key.

1.  SECURITY LIGHTING FOR WALKWAYS AND DRIVEWAYS.

Outdoor post lamps and path lighting help to expand your outdoor environment, providing a tailor-made illumination toward the front door, deck, patio +/or garage.

2. DECORATIVE LIGHTING FOR HOME ENRTY ZONES.

An outdoor hanging lamp and/or wall lanterns add a customized finish and are available in a myriad of styles to complement homes from traditional to ultra modern.

3.  TASK LIGHT BY THE FRONT DOOR AND GARAGE.

Direct focused illumination on key holes and security pads should be bright enough to allow for easy access and visibility when you are entering and leaving your home at night.

4.  ACCENT ILLUMINATION TO HIGHLIGHT HOUSE NUMBERS

Make sure that your home is properly illuminated for guests as well as delivery people and emergency vehicles.  All too often, help is delayed in emergency situations because house numbers are not clearly visible at night and outdoor lighting is insufficient.

5.  “SHIELDED” LAMPS THAT EXPAND OUTDOOR LIVING SPACE AND ACCENTUATE IMPORTANT ARCHITECTURAL FEATURES.

Properly shielded outdoor lighting fixtures expand and beautify your home, without creating glare or causing visual discomfort to visitors and neighbors. A good lighting design with energy-efficient fixtures will increase the value of your property and provide majestic outdoor lighting effects.

LET’S GET STARTED…

*Rule of thumb for sizing outdoor wall lanterns:  The height of the lantern should be based on the height of the door.  If brackets are to be installed on either side of the door, they should measure about one-fourth the height of the door.  If using only one lantern, size up to about one-third the height of the door.

** “Dark Sky” compliancy and light pollution:  Light pollution is any undesirable effect of artificial light, including glare, light trespass and decreased visibility at night.  Many manufacturers offer “Dark Sky” versions of their outdoor lighting products, which “collar” the light bulb around its base to block superfluous upward emissions of light.

-Match outdoor fixture styles to the decor of your interior space.  Whether you go with classic and elegant traditional outdoor lighting or sleek and contemporary, your outdoor post lamps, hanging lamps and wall lighting should complement that style.

-If you have custom designed hardware on doors, find a finish that will work well to complement this detail.

-Don’t neglect the side yard and dark areas by side windows;  Include at least one low-level outdoor lamp for nighttime security.

-Look for finishes and outdoor hanging lanterns, post lamps and flush fixtures that are guaranteed to last.  Check out warranty information on the latest outdoor lighting fixtures; some include a life-time guarantee on all finishes and parts.

-Make sure to view your outdoor lighting after dark before signing off on a project; make necessary adjustments to refine your outdoor lighting design, focusing the light exactly where it is needed for an aesthetically pleasing look and polished illumination for safe navigation and security lighting at night.
