Understanding the Affects of Dimming CERAMIC TECHNOLOGY OPERATED ON DIMMING BALLASTS All EYE Metal Halide lamps, except, Multi-Metal Ace™ family, can be dimmed up to 80% of the lamp nominal wattage on EYE Lighting approved dimming ballast systems. Lamps must be operated at least 15 minutes at full power prior to dimming. Dimming systems that…
Understanding Spectral Distribution Chart WHAT IS A SPECTRAL DISTRIBUTION CHART? The spectral distribution chart is a visual representation of the light spectrum produced by a lamp. It is a graph showing the relative intensities of a light source at each wavelength.These charts can be used to compare the energy levels of various light sources. They…
Understanding LED Testing In order to determine how long LEDs will last or how a luminaire will survive in wet weather, there many tests they go through. Here is a general list of the types of tests that LED chips, lamps and luminaires can go through. How are LEDs tested? IES LM-79-08 Purpose Provide procedures…
Understanding LED Distribution Types With LED technology it is now easier than ever to predict and direct where the light will go. This is only for a quick reference on what each Distribution Pattern will generally look like. Actual luminaire distribution pattern depend on the applications and the environment. Type I The type I distribution…
Commonly Used LED Terms Light Emitting Diode (LED) A pn junction semiconductor device that emits incoherent optical radiation when forward biased. The optical emission may be in the ultraviolet, visible, or infrared wavelength regions. LED Die A small block of light-emitting semi-conducting material on which a functional LED circuit is fabricated. EYE Lighting LEDioc LED…
Understanding the Benefits of LED Lighting Saves Energy; LED lights use 50-90% less power than traditional lighting Saves money; lowers energy bills Saves the environment; less waste and disposal hazards Extremely long life lasts 4-5 times longer than traditional lighting Reduced maintenance costs; Replacement cycle costs are drastically reduced Reduces ambient heat; generates far less…
Understanding LED Drivers What is an LED Driver? An LED driver is a self-contained power supply that controls the amount of current and voltage supplied to an LED light. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED chip. LED…
Understanding LED Lighting What is LED Lighting? An LED (Light Emitting Diode) is a special diode that uses a semiconductor chip to produce light when an electric current is passed through it. LED lights are extremely energy efficient and long lasting making them ideal replacements for traditional power hungry halogen and standard high intensity discharge…
Understanding HID Lamp Operating Positions Lamps must be operated in their specified operating positions in order to maximize lamp performance and life. Incorrect operating positions may also create the possibility of a lamp rupture.Because of these factors it is imperative that users adhere to the specified operating positions and fixture requirements. The following chart shows…
