LED lighting is becoming increasingly popular to use in buildings and for good reason: they have a long life, are highly energy efficient, can be dimmed, and produce a low amount of heat and no UV rays.
There’s one common misconception surrounding LED lighting, however. Many believe that LEDs work the same up until the lights go out. In reality, though, LED lighting slowly loses its brightness, many times unbeknownst to the building user. Unlike fluorescent lamps that will completely fail (which makes it easy to tell when a light needs replaced), LEDs don’t go out completely, so you’re left to people’s perceptions.
LED Rating System
Like all other lighting, the rating system of LEDs is an estimate of the amount of hours a bulb will burn before it needs to be replaced. The tricky thing with LEDs is that their lifespan is determined to end when the bulb can only achieve 70% of their initial lighting output. The bulb will slowly continue to depreciate until the user finally figures it out and replaces it.
Light Meter
If you’re having trouble determining whether or not an LED light has reached the end of its lifespan, it’s best to use a light meter. Light meters generally range from $50-$300 based upon what you need them to measure.
The video below, by Aurora Lighting, has some great illustrations which should help further illustrate how the lifespan of LEDs work:

Smartphones have replaced a lot of different objects and materials on today’s construction site. They’re used for pictures, video and audio recording, and note taking, among many other uses. Beyond the typical functions most phones already have incorporated within them, there is now a significant market of accessories designed to make your phone even more useful on the construction jobsite.
We’ve compiled a list of 5 different accessories that you can buy to further enhance the power of your smartphone for construction.
Painters are typically one of the last subcontractors on any construction site, who do their best to beautify the drywall with the colors of the architect's or interior designer's choosing. Some painters are also responsible for mudding drywall, patching holes, sanding, and caulking.
Let's take a look at how an average painter's hourly wage compares in each state...
In doing the research for this analysis, I learned something interesting about the plumbing profession. The term "plumber" comes from the Latin word "plumbum," which means lead. Seems fitting in a profession, fairly or unfairly, stereotyped for exposed butt cracks.
In Roman times, plumbers often worked with lead for conduits, drain pipes, and making baths. Plumbers now work with a variety of different materials, including copper, PVC, ductile iron, among others.
In January of this year, tragedy struck a Florida construction company when 3 construction workers died while working underground below a newly paved road. After the first worker entered the hole and collapsed after entering the confined space through a manhole, the second went in to rescue him and also collapsed, followed by the third. After a post-incident investigation, OSHA has released their findings, as well as several fines.

No matter what our specialty, once we’ve been on a construction-related job a few years, we’ve got a few stories to tell. A lot of them start with “How the he**” did that get there, or “YUCK!”
The 2017 Milwaukee Tool New Product Symposium (NPS) was held last week at Milwaukee’s headquarters and it proved to be a whirlwind of new products and information from the red brand. Over 80 new tools and accessories, which will be released throughout the remainder of 2017, were presented to dozens of media representatives, including construction magazines, YouTubers, Instagrammers, and your favorite construction blog (Construction Junkie, obviously).
After flooding our social media pages with Milwaukee information and gathering our thoughts from the event, we’ve come up with our 9 biggest takeaways from the event, in no particular order.
Announced at the start of the new year, FLIR has released specs on its new and updated line of thermal imaging devices and accessories. We have talked about the many reasons that contractors should use a thermal imaging camera and the FLIR ONE mobile accessory in the past and it has returned in 2017 with a new Gen 3 Pro Model. They have also announced their FLIR C3, which is the size of a standard digital camera, offering great accuracy and detail in a compact form. Lastly, FLIR is also offering the FLIR Duo, which will remind you of an action camera. Intended to be used on that fancy new drone quad-copter you got your kids for Christmas.
Once again technology has made our old proverbs obsolete, take the old “square peg/round hole” saying, for instance… I’m sure there’s a joke in there somewhere, but I can't find it. Currently your choices for hole saws and drill bits are round and more round, so those pesky square holes that need cut for electrical boxes require a jab saw or a router. It’s not terribly difficult to cut square holes using those methods, but, one company has taken it upon themselves to make the process much quicker.
At Milwaukee’s New Product Symposium in June of 2017, the company then showed their commitment to the 12-volt platform with the announcement of the Generation 2 M12 Hammer Drill and Impact Driver. The hammer drill and impact driver were since released in January 2018 and we’ve had the opportunity to test the tools for ourselves. The drill/driver is yet to be released as of the publish date of this article.
