As solid-state light sources, LEDs have very long lifetimes and are generally very robust. Quality LED products have the potential to last two to three times longer than conventional traditional lamps. Look for products that have been qualified by ENERGY STAR® or Design Lights Consortium (DLC).
When properly matched to their application, quality LEDs can last longer. The long lifetime of LEDs reduces the need to replace failed lamps, and this can lead to significant savings in lamp replacement labor.
LEDs are high-efficiency light sources. The directional nature of light produced by LEDs allows the design of luminaires with higher overall efficiency that use less energy.
LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.
LED's "like" low temperatures and will startup even in subzero conditions making them a particular advantage for certain applications such as Cold Storage.
A bulb's capacity for producing correct-looking colors is measured by its score on the Color Rendering Index (CRI). While most LEDs score in the 80's, many LEDs score in the 90's. In addition to CRI many products now publish their R9 value, which refers to how an LED renders a saturated Red color sample. For best color look for products with a high CRI and an R9 value >0.
LEDs do not contain mercury and in many cases steps are being taken to replace lead-containing solders (used mainly to fix LEDs to circuit boards) with lead-free material, in line with European directives. The energy-efficient nature of LEDs also makes them environmentally friendly.
LEDs can very easily be dimmed. Use of LED sources with controls that eliminate over-lighting can help you cut back your energy usage and greatly enhance savings.
LED technology is beginning to surpass the quality and efficiency of existing lighting technologies—but not all LED lighting is created equal. That is why PG&E and other California utility companies are working to create programs that offer rebates for pre-qualified LED lamps and fixtures that meet stringent performance specifications such as those validated by third-party ENERGY STAR® and Design Lights Consortium testing.
Fluorescent lamps currently dominate the commercial sector, where they account for 80 percent of installed lamps.* However, Linear LED lighting technology — like LED technology in general — is receiving a lot of attention now because it has the potential to offer even greater energy efficiency and improved light quality with longer lifespans and better control. Modern LED lighting solutions are available for places where fluorescent lights now predominate, including office spaces, classrooms, healthcare facilities, retail space and more.
Three main categories of LED products are currently available for retrofitting existing fluorescent lighting systems. Selecting the best option will depend on a number of factors, including the condition of your current system; your desired light level, ceiling accessibility and your initial and on-going economic goals for the upgrade. Your PG&E lighting expert can help you assess your situation and choose the best LED solution.
Linear LED Replacement Lamps
Today's quality Linear LED replacement lamps are easy to install and fit most existing fluorescent lamp sockets/fixtures right out of the box, making them the ideal upgrade solution where energy savings and easy installation are key considerations. These products work on the existing T8 electronic ballast, therefore the life of an LED Replacement Lamp is directly related to remaining life of your existing ballast. While there are lamps that will operate on T12 systems, PG&E recommends upgrading the T12 ballast to an T8 elctronic ballast or Linear LED Retrofit kit LED.

Linear LED kits are designed to replace existing fluorescent lamps and require some form of rewiring (such as replacing the ballasts). Each kit typically comes pre-packaged with all the required components to complete the retrofit, making installation easier. Kits are available as light-bar and lamp-style fluorescent lamps for Strips, Industrial style and surface mount lensed fixtures as well as Troffer kits with new door frames and lens.
Dedicated LED Luminaries
Dedicated LED luminaires can often easily replace existing linear fluorescent luminaires. While typically higher in cost (because it is a complete light fixture), this option often provides the all the benefits of LED technology in a well-designed package that often allows for simple redesign or reduction in the fixture layout.

Earn incentives for replacing fluorescent refrigerated and frozen food case lighting systems with qualified LED fixtures.
Frozen food and refrigerated display cases in supermarkets are typically illuminated by fluorescent sources. Although they are reasonably efficient and reliable, fluorescent sources operate best at indoor temperatures of 60 to 80 degrees Fahrenheit. Light output for fluorescent lamps can drop by as much as 60 percent in cold temperatures. LED lighting, on the other hand, performs better as the temperature drops.
