FAQ

What differentiates Firefly Illumination exterior fixtures from other T5HO products?

Firefly Illumination utilizes an industry-first plug and play technology, which significantly reduces installation time, enhances safety, and provides the only upgradeable fixture on the market. Our removable gear tray allows for quick and easy maintenance.

How do Firefly Illumination fixtures perform in hot weather applications?

The ballasts we offer are hot weather rated to 194ºF.

How do Firefly Illumination fixtures perform in cold weather applications?

Our ballasts are rated to -22º F and the lamps and ballasts are fully enclosed. The expected reduction in light output from florescent lamps in very cold temperatures is overcome by fully enclosing the lamps and ballasts. Once the lamps turn on, the space inside the enclosed housing warms, and light output is not affected by outside temperature, but rather by that of the interior.

Do Firefly Illumination fixtures qualify as “Dark Sky Compliant”?

Yes, Firefly Illumination fixtures provide a cut-off below 85 degrees.

Can the Firefly Illumination fixture be attached to a square and/or round pole?

Yes; our mounting arm bolts directly onto a standard square pole, and we offer adapters for round poles to make installation quick and efficient.

What is the lead time required to receive Firefly Illumination fixtures?

Our typical lead time is four to six weeks, from date of order, however, in many cases that lead time may be reduced.

What options are available for a Firefly Illumination fixture?

We can provide numerous options to customize our products to best suit your needs. These options include photo cells, occupancy sensors, bird deterrents, adjustable tenons, and emergency ballasts. We are a custom lighting manufacturer and stand ready to help the end-user improve their lighting experience by using Firefly Illumination fixture options. We stand ready to do whatever is necessary to accommodate your unique needs.

How can I replace a 1000 watt HID fixture with only 351 watts of fluorescent?

There are two reasons; first, the output from an HID lamp will degrade 25-45% at 40% of its life; which is approximately two years of use. Output from a T5HO lamp will degrade 5-7% at 40% of its life; approximately five years. Second, the 5000k florescent lamps used in Firefly Illumination fixtures provide a much whiter and natural light that is better utilized by the human eye. This allows you to see more clearly, and have better color recognition with fewer lumens.

How much can I save by switching from HID to fluorescent?

Energy usage per fixture is typically reduced by 45 to 65%. This savings may be enhanced further by using occupancy sensors or other energy management systems. These components allow for some ballasts to be turned off when less than full light is necessary.

What is Firefly Illumination’s warranty?

The standard Firefly Illumination warranty period is five years from date of shipment. Ballasts and lamps are covered under that individual manufacturer’s warranty; which is typically five years for ballasts and three years for lamps.

Do you offer options if I don’t have available capital to pay for my lighting retrofit?

Most utility companies offer rebates that will cover 15-75% of the cost of new fixtures and installation; some even offer no-interest financing. The return on investment for such a retrofit is measured in months. Firefly Illumination also has a modified capital lease program available through our financing partner, Northstar Leasing Company. Please contact us for more information.

Where are Firefly Illumination fixtures manufactured?

Firefly Illumination products and their components are American made. All of our fixtures are fully assembled in our Mesa, Arizona facility. Except for the aluminum extrusions and powder coating, all components are manufactured in-house. The lamps and ballasts we install are purchased from major manufacturers such as GE, Sylvania, Advance, and Robertson.

How long do lamps and ballasts typically last?

Most modern florescent T5 & T8 lamps are rated for 30,000 to 36,000 hours. Lamp life is enhanced when lamps are left on for at least 3 hours at a time, as is usually the case in an exterior application. 36,000 hours equates to eight years when used 12 hours per day. We also offer a 60,000 hour extended life lamp option.   We use ballasts from major manufactures such as GE, Sylvania, Advance, and Robertson. These ballasts are typically rated for 50,000 starts, which would equal 22 years at six starts per day.

Where can I get replacement parts?

Our lamps and ballasts are the primary items that will require replacement over time. We use standard components that can be purchased off the shelf, from any electrical supplier.

What is the CRI (color rendering index) for Firefly Illumination fixtures?

Firefly Illumination fixtures utilize the latest in T5 and T8 fluorescent technology, and provide a CRI of 85 or higher.

Can Firefly Illumination fixtures provide a wide or shallow light spread?

Yes. The standard Firefly Illumination fixture provides a type five light distribution. Other distributions can be provided through different reflector designs, as well as different reflector materials. Our engineering department welcomes the opportunity to discuss whatever needs you may have.

Do Firefly Illumination fixtures have .ies files?

Yes, all of fixtures have been tested by Lighting Sciences Inc, based in Scottsdale, AZ. You can find the .ies files on our website, or upon request, we can send specific files to Lighting Reps and Distributors.

What is the EPA rating for the Firefly Illumination fixtures?

EPA ratings for our fixtures are listed on their cut sheets. The combination of our low profile and light weight aluminum fixture, provide an EPA rating that is typically lower than the fixture being replaced. For example, the EPA of an FFX 246 is 1.80, while the EPA for a typical 1000 watt metal halide fixture typically exceeds 3.0 .

We have 480 volt power. Will Firefly Illumination fixtures work with this voltage?

Yes, our four foot fixtures include an option for 480 volt ballasts or a step down transformer. Our two foot fixtures use a step-down transformer to convert 480 volt power to 277 volt.

How do Firefly Illumination fixtures perform in coastal conditions?

All of our exterior fixture hardware is stainless steel. These fixtures also employ six interior gaskets; including those adhered to both endplates. We offer an upgrade to our standard paint for coastal environments. This powder coat paint process complies with AAMA #2605 and is manufactured specifically for salt spray areas.

Are Firefly Illumination products LEED compliant?

Firefly Illumination high efficiency products meet the requirements of reducing energy consumption, and are an excellent choice for projects seeking LEED certification.

Is Firefly Illumination a UL listed manufacturer?

Yes; our factory is regularly inspected by Underwriters Laboratories, and we have a UL rating as well as a CUL rating for use in Canada.

What are the design specifications for the gaskets and how do they hold up in warm environments?

The vinyl gaskets at each end of the fixture are rated to perform in extreme heat conditions up to 180F.

Does this technology have an issue with mercury?

There is an understandable desire to move toward less mercury escaping into our environment. While florescent lamps do contain mercury, (approximately 4 milligrams per lamp), we believe the use of fluorescent lamps is one of the best ways to reduce the amount of mercury released into the environment. The single greatest source of mercury release comes from coal-fired power plants which account for roughly 40% of all mercury produced by human activity. Coal plants also produce approximately 50% of electricity used in the US. Replacing a single 1000 watt metal halide lamp with a six lamp T5 florescent fixture, will save 3193 kWh per year, thereby preventing the release of 75 mg of mercury from a power plant. Over its 36,000 hour life, a six lamp T5HO fixture will prevent the release of 613 mg of mercury. Recycling is recommended for all fluorescent lamps and when properly done, there is no mercury release.
