LED Lighting Frequently Asked Questions
Answers on dimming, lifespan, certifications, emergency battery backup, rebates, shipping and lead times.
A:While most LEDs are dimmable, the LED driver quality and its compatibility with the control are two factors that determine true dimming performance. Not all LEDs are going to be compatible with your current dimmer switch, so be prepared for a little bit of trial and error. While dimming is technically possible, be sure to double-check that everything is going to be compatible and will function to your standards.
A:Many LED lights are waterproof or water-resistant, making them ideal sources for interior and exterior lighting of water-intensive areas.
A:LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 5-6 times longer than a typical CFL. Used 12 hours a day, a 50,000-hour bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!
A:LED bulbs outperform CFLs in almost every way. They use less energy for the same light output, typically last several times longer, and turn on instantly at full brightness with no warm-up time. LEDs also perform better in cold environments, handle frequent on/off switching without shortening their life, and are far more durable because they have no fragile glass tubes. Unlike CFLs, LEDs contain no mercury, so they are safer to handle and easier to dispose of.
A:LED lights are as safe to the eyes as any other artificial light source. They are not like lasers, the light is not focused to a single point, and the intensity is comparable to traditional bulbs and halogen lamps.
A:The simple answer is yes; if the LED bulb uses less wattage than your fixture.
A:Yes, the manufacturer can provide the proper control that works with a particular fixture.
A:No, its design is very similar to incandescent bulbs, so it can be a seamless transition to LED.
A:Yes.
A:In many cases there is no need to replace them.
A:LED bulbs use over 75% less energy than incandescent lighting.
A:Dimming LED fixtures saves additional energy, reduces heat and can extend fixture life. It also lets you adjust light levels for different tasks, times of day or occupancy, which improves comfort and productivity. In many commercial projects, dimming controls help meet energy code requirements such as California Title 24. For reliable performance, the dimmer must be compatible with the fixture's driver: commercial fixtures typically use 0-10V dimming, while many residential-style fixtures use TRIAC (phase-cut) dimmers. See our Dimmers Specification page for compatible models.
A:Yes. Today's LED fixtures are designed with built-in heat management, and E2 Lighting's enclosed fixtures, including vapor tights, wraparounds and wall packs, are engineered specifically for enclosed and sealed use. If you are installing a standalone LED replacement bulb inside an existing enclosed fixture, choose a bulb that is rated for enclosed fixtures, since heat build-up can shorten the life of bulbs that are not.
A:Yes, LEDs are very similar to consumer electronics and quality really matters. For an LED to function properly and provide an acceptable light output, all the components must be built to last. It’s always a good idea to buy from a manufacturer and retailer that you’re confident will stand behind the product.
A:You need to know the wattage of each light currently being replaced and the wattage you are replacing it with. Then subtract the difference and multiply by the hours of use per day and your cost per kWh; multiplied by 365 days this gives you an annual cost saving amount.
A:Although it may seem counterintuitive, many electric utility companies offer significant financial incentives to install energy-efficient equipment that saves energy and money for the end customer. This also helps reduce the carbon footprint to the environment.
See the rebate guide →A:Prescriptive lighting rebate programs differ from point of sale rebates in that they are not designed to be claimed instantly. The incentives are paid out based on parameters where each kWh saved represents a rebate value for the replacement fixture, as assigned by your regional utility company.
See the rebate guide →A:Yes. LED lights can work with motion sensors with the right configurations. A lot of lighting technologies today make use of motion sensors attached to LEDs. This will continue to add further energy savings.
A:LEDs contain no mercury, so a broken LED is safer to clean up than a broken CFL. However, LEDs are electronic products, so please dispose of them according to your local electronic waste or recycling rules rather than in household trash.
A:Most standard LED warranties last three to five years and cover the cost of replacing the product only. If you hired electrical contractors for the installation of the product, that labor is likely not covered by the manufacturer’s warranty, though a handful of manufacturers may cover that cost in addition to the cost of replacement.
A:Useful life has been defined as the number of hours an LED device can operate until it emits only a certain percentage of its original lumen output.
A:Based on how long a fixture is illuminated per day, here’s what 100,000 hours works out to:
24 hours a day — 11.4 years
18 hours per day — 15.2 years
12 hours per day — 22.8 years
8 hours per day — 34.2 years
A:Yes.
A:Yes. Each light is aged over 8 hours before packing for shipment.
A:Yes. Emergency battery backup is E2 Lighting's core specialty. We offer one of the industry's most extensive ranges of LED fixtures with pre-wired emergency battery backup, including troffers, flat panels, downlights, linear strips, high bays, wraparounds, vapor tights, wall packs and canopies. Our emergency products are designed to meet UL 924, NFPA 101 and California Title 20 requirements and provide 90 minutes of emergency illumination during a power outage. For existing fixtures, we also offer standalone LED emergency drivers and T8 emergency battery backup tubes. Self-diagnostic testing is available on select models. Contact our emergency lighting specialists for help choosing the right solution for your project.
A:Yes, select models are fire rated, including our 4-inch and 6-inch LED slim downlights, with and without emergency battery backup. Look for "Fire Rated" in the product name, and check the product's spec sheet for the specific fire rating details. Other housings are not fire rated.
A:Our products are designed to be easy to install with no special tools or experience needed, using conventional dimmers and wiring. Please reference our installation information for detailed documentation.
A:All E2 Lighting LED products are UL certified or ETL certified. Please visit the UL website to find more details about our certifications to UL standards.
A:You need an audit walkthrough to identify the amount of light required for your specific space. Each space has a recommended lux requirement and you can increase or decrease the lux to your preference after you have reviewed the standard.
A:We have been in business since 2013.
A:ACH, check, credit card, and wire.
A:We use USPS and UPS for small parcels, and for any shipment over 150 lbs we order freight (LTL). For a freight shipping quote, please let us know if you need lift gates or if the delivery address is a residential or commercial location.
A:If we have it in stock the lead time is a 24-hour turnaround. We can also do made-to-order, shipping via air cargo, air freight, or ocean shipment.
A:We ship throughout the United States, including Alaska and Hawaii.
A:No, our product is post-duties. We are domiciled in the state of Texas and only collect sales tax in the state of Texas.
