LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED

LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED

Posted by on for ProLampSales

The effects of power quality on LED lighting performance generally receive little attention prior to installation for most commercial building applications. Power quality issues such as dips, harmonics, interruptions, transients and surges can result in expensive, early replacement of damaged or failed LED lighting equipment. While facility managers involved with smaller commercial projects may be able to ignore power quality without much consequence, larger industrial LED lighting projects, such as the replacement of existing HID...

LED Troffers Offer Strong Case To Replace Fluorescent

LED Troffers Offer Strong Case To Replace Fluorescent

Posted by on for ProLampSales

When comparing LED troffers and retrofits to fluorescent troffers, the most LED fixtures will either exceed or match the specifications of the fluorescent fixtures. LED lumen output often matches that of various fluorescent configurations but it, along with control compatibility, requires careful consideration to ensure the LED installation will meet the needs specific to the application.

How to Make Sure Photocontrols Are Compatible With LED Lighting

How to Make Sure Photocontrols Are Compatible With LED Lighting

Posted by on for ProLampSales

Photocontrol devices use photocells to determine ON/OFF status of outdoor lighting based on the ambient light level. While generally understood as responding to visible light, some photosensors also respond to infrared (IR) and ultraviolet (UV) radiation. Normally used for roadway, area, parking, flood and security lighting, photocontrols automatically control the ON/OFF cycle to optimize the effectiveness of the lighting and maximize energy savings. In daylight harvesting applications, the photocontrol is mounted inside the occupied space...

LED Downlight Options for Small Commercial & Residential Applications

LED Downlight Options for Small Commercial & Residential Applications

Posted by on for ProLampSales

The number of recessed downlights in small commercial and residential environments often exceeds all other types of light fixtures in the building. Tucked neatly inside the ceiling, these fixtures manage to be both an unobtrusive and an effective source of illumination for many types of spaces. The traditional light source for these downlights has been the incandescent BR30 (3.75" diameter) or BR40 (5" diameter) reflector floods. Unlike architectural grade downlights, the typical small commercial and...

LED Linear T8 Retrofits: Sorting Through The Options

LED Linear T8 Retrofits: Sorting Through The Options

Posted by on for ProLampSales

One look at the LED T8 retrofit lamp and installation options can quickly make you want to run for cover - or give up and live with fluorescent. The later approach, while not as forward-looking as LED, makes some sense especially if you are comparing the 30,000 to 40,000 hour T8 fluorescent lamps now available with 35,000 to 50,000 hour LEDs. From a low risk perspective, not to mention low up front costs, current generation...

Replacing HID with LED in High Bay Applications Offers Potential Benefits But Requires Careful Analysis

Replacing HID with LED in High Bay Applications Offers Potential Benefits But Requires Careful Analysis

Posted by on for ProLampSales

Learn about the benefits and considerations of switching from metal halide and HID lighting systems to LED. While the energy savings and maintenance costs are better with LED HID replacements, does the technology live up to the promises of LED lighting manufacturers?

Time Switches Offer Effective Lighting Control For Time of Day Driven Applications

Time Switches Offer Effective Lighting Control For Time of Day Driven Applications

Posted by on for ProLampSales

Time switches, or timers, for lighting control allow for time of day ON and OFF scheduling for individual lights or lighting systems. Generally, time switches work best with outdoor lighting where the time of day, along with sunset and sunrise, determine when lighting is on or off. Indoor applications for timers might include basic residential control of a single fixture to provide the "lived-in" look when the occupants are away from home. There are three...

Is Overall Energy Efficiency in Lighting a Pipe Dream?

Is Overall Energy Efficiency in Lighting a Pipe Dream?

Posted by on for ProLampSales

A study by Rutgers University indicates that cheaper, more efficient lighting may lead to more lighting being used by consumers and institutions. One likely result -- people will use more lights if they are cheaper to operate, which won't reduce the overall energy usage. According to an article from InsideClimateNews summarizing the findings, the cost of LEDs will keep coming down due to a switch from rare earth elements (REEs) to earth-abundant materials that are...

Consider Maintenance & Lighting Needs for Retrofits

Consider Maintenance & Lighting Needs for Retrofits

Posted by on for ProLampSales

When it comes to lighting retrofits, we often get focused on utility rebates and energy savings to the exclusion of all other issues. If the energy company is offering $10 per bulb and $20 per fixture, it seems like a no-brainer to go ahead with a complete retrofit, right? Rebates and energy savings don't tell the entire story, however. They are an important selling point to replacing older, inefficient lighting technology with newer LEDs, but...

Leasehold Criteria - Benefits of LED Retrofits

Leasehold Criteria - Benefits of LED Retrofits

Posted by on for ProLampSales

This is the latest in our short series on benefits of lighting retrofits. In the first article, we examined reducing load on regional utility companies and explored why it makes economic sense for utilities to offer rebates for lower energy usage, rather than simply upgrading equipment to meet higher energy demands. The second article looked at reducing maintenance costs for commercial and industrial spaces. When a building has hundreds or thousands of light bulbs on...
