LEDs have a projected lifespan of 50,000+ hours, which supersedes most traditional lighting options available in the market today. This robust feature makes LEDs a top choice for residential homes and industrial facilities.
The lifespan of LEDs is affected my numerous factors, from design to environment. Below takes a closer look such factors.
Heat and LEDs
Heat is a leading cause for the deterioration of LED lighting systems. Because of this, a heat sink is typically installed with the unit to ensure proper cooling. Such components could be made out of ceramic or incorporate a passive cooling mechanism (for instance, horizontal fins). These features are effective when the LED fixture is positioned properly.
Incorrect mounting applications may amplify the accumulation of heat around LEDs. For example, a recessed LED lamp mounted on a low ceiling in a garage may cause the light to degrade at a faster rate, without proper protection. A solution to this issue would be to utilize an open mounting setup to allow air flow around the luminary.
When calculating the general lifespan of LED lights, it is important to take lumen maintenance into consideration. This term refers to the output of the LED lamp after a certain period of time. For instance, an LED lamp with an L50 rating refers to 50 percent of output after the unit’s intended lifespan. An L70 lumen maintenance rating provides 70 percent of output after the LED lamp’s estimated lifespan. Lumen maintenance ratings of LEDs are specifically useful for outdoor LEDs and for lighting systems with emergency applications.
Furthermore, high lumen maintenance ratings are ideal for parts of the home where detailed tasks are conducted, which can ensure optimized illumination before the light completely fails. LED fixtures in general locations do not need high lumen retention due to the presence of other lighting systems in the area.…

Several LED bulb designs available on the market today were adopted from traditional lighting standards, during the era of incandescent and halogen luminaries. For homeowners looking to switch over to LEDs, it is important to know about conventional bulb sizes, to ensure compatibility during installation. With this in mind, this article compares the differences between a LED PAR 30 and a BR 30 LED bulb.
Characteristics and Angles
A PAR 30 LED bulb provides spotlighting features, with tight angles lower than 45 degrees. The acronym ‘PAR’ stands for Parabolic Aluminized Reflector. These types of LED bulbs can be used indoors and outdoors, depending on the ratings of the unit. PAR LED products may be offered at various angles, such as: narrow spot, narrow flood or wide flood. These options range from 5-15 degrees to 45 degrees.
A BR 30 LED bulb offers the opposite lighting characteristics, compared to a PAR 30 LED bulb, in a sense that the angles are noticeably wider. This is easily distinguishable, based on the term ‘BR’ which stands for Bulged Reflector. This type of LED bulb provides lighting angles wider than 45 degrees.
Based on the lighting characteristics of the LED bulbs, we can determine their respective applications. PAR 30 LED units illuminate specific objects or targets, making them ideal for track lighting systems, illuminating landscapes, paintings and general security lighting. It is important to highlight that when the bulb is used outdoors, they must carry specific waterproof ratings.
A BR LED bulb is useful for lighting up wide spaces inside homes. Such objects and locations include living rooms, kitchens, hallways and doorways. To maximize the unit’s beam spread, it is recommended to use this type of LED bulb with recessed lighting configurations or with lighting guards, especially with BR LED bulbs that offer very wide lighting angles.…

LEDs are capable of superior illumination, which can be extremely powerful in homes and small spaces. To address such concerns, homeowners may choose to diffuse LED hot spots with acrylic or polycarbonate sheets.
Both options are effective in mitigating strong light beams and trespass, for softer lighting conditions. However, the materials vary greatly, when it comes to sturdiness, transmission and cost.
Acrylic vs Polycarbonate
Starting with acrylic, the material is a transparent plastic that is capable of withstanding rough impacts (shatter resistant). Comprised of a synthetic polymer of polymethyl methacrylate (PMMA), this type of sheet is sold under several names, such as Plexiglass and Optix. Acrylic sheets can be found on aquarium tanks and protective shield barriers in commercial skating venues.
Polycarbonate, on the other hand, offers another level of sturdiness and can withstand extreme impacts, vibration and dust (when sealed properly). With light transmission capabilities greater than 90 percent, the material is recommended for transparent lighting requirements over the target area.
Additionally, polycarbonate offers exceptional resistance to fluctuating temperatures. Such sheets have a threshold up to 120 °C, which is considerably higher than acrylic light diffusers.
Which One is Right for Me?
For homeowners, choosing between acrylic and polycarbonate sheet diffusers for LED spotlights highly depends on the application of the fixture. For outdoor spaces, polycarbonate sheets are recommended because of their durable features. Moreover, in outdoor environments, light diffusion requirements are usually minimal due to the wide space.
Indoor light diffusion can be achieved with acrylic sheets, due to their robust optical properties. The lightweight material does not lose its color easily, providing up to 10 years of transparent and reliable performance. Compared to other plastics in its group, acrylic is moldable, which allows lighting manufacturers to create covers that adhere to the form and design of the unit.…

Inside homes, hallways are tricky locations to get right when setting up lights. The spaces are extremely narrow, increasing the risk of glare and uneven beam distribution. LED lights present numerous viable solutions for hallways, due to their compact and reliable features. The units can take on unique configurations and settings, to make lighting systems in hallways more functional.
LED Track Lights and Wall Scones
Narrow hallways benefit from thin and long units, such as LED track lights or LED strip lights. Starting with the first option, LED track lights are fixtures mounted on a single-lane track, which is installed on the ceiling. Homeowners can add (or remove) as many lamps as they want on the track. Mounting LED lights above ground may help reduce tampering and direct contact, for individuals with kids or curious pets.
Moreover, the fixtures can be positioned individually to target hard-to-reach areas. This option is perfect for residential hallways with artwork and photos.
Recessed can lights may also be used for overhead lighting in hallways. This type of fixture only provides down-lighting features (no adjustable light head). An advantage to using recessed can luminaries is the application of cut-off shields for beam direction.
LED wall scones are also ideal for hallways. Unlike LED track lights, these units offer up or down lighting features. Because the fixtures take up space, they are usually found in wide hallways.
Recommendations for Installation
Hanging LED lights in hallways are not recommended for spaces with short ceilings. Surprisingly, this is practice is common in older homes that use chandeliers. Hanging LED fixtures are notorious for creating glare and may present some issues for tall individuals.
If the hallway leads to a staircase, it makes sense to provide additional lighting at the transition from the ground to the first few steps. For illuminating dark corners, homeowners may apply table lamps or tall lamps on stands.…
Flood lights might not be anything new, but LEV LED spotlights are – only having gained significant traction on the exteriors of warehouses and commercial entities over the last few years. The bottom line is, outdoor LED flood lights have become a popular alternative to incandescent flood lamps for the same reason that the 40 watt incandescent light bulb is being replaced by LEDs in the home – for every one of the technological benefits which may have become realized.
Knowing that, here’s a check out 5 tips for the functional installing your outdoor LED flood light…
Power Before Installing Outdoor LED Overflow Lights
We kick things off with a tip that lots of DIY’ers – be it in the home or commercial setting up – fail at, and that’s connecting the power only after they’ve installed the overflow light. It should continually be the other way around – hook up the energy before you install it.
The reason for this rule is simple. Consider it:
- If you connect the power after you set up the light, you might realize you incorrectly situated the light and it’s not performing you wanted. You may even recognize that you’ve wired the lighting incorrectly.
Proper Placement of the Lights
Generally speaking, the placements where outdoor LED spotlights can do the best job are in the edges of the building and near the roof. Installing too near the ground, although it will translate to an easier installation, won’t give a wide portion of coverage for the facility. Corners, on the other side, tend to be a favorite lurking location for wrongdoers, basically because these areas are usually left darkened.
Know Your Limitations – Ask for Help When it’s needed
In lots of commercial applications, LED spotlights installation may well not be for a person who fears heights. That’s because quite often a ladder is necessary to complete install (although when you can gain roof access and can adequately install it that way, that is a practical option too).
Generally in most circumstances, a typical ladder will not be enough to complete the job – your best bet is probable an expansion ladder with the capability to lengthen up to 20 feet or so, with regards to the size of the building.
Know Your Electrical Current
LEDs have a low energy pull, so issues with the circuit breaker aren’t an enormous issue when it comes to outdoor flood light set up. What may be a concern, however, is if you have more than one flood light and are trying to hook up multiple incandescent and LED ones collectively. So why is this such an issue?
Because incandescent light bulbs draw more ability than LEDs, so there’s the potential for the power get to essentially overload and demolish any LED spotlights lighting. So ensure that incandescents and LEDs are run out of separate outlet stores.
Safety First – Test Before Sealing
Before you finalize the task and caulk the area between the wall and the flood light mount, it is important to test all operation of the overflow light to ensure other features, such as motion detection, are working properly.
Once you finalize assembly, it’s far more difficult to make any changes or alterations to the electric powered wiring. Just like we talked about in tip No. 1, you want to preview the final product before you finalize anything.
