Electroluminescent panels require high voltage at high frequency to work properly. We have inverters for Split Electrode and Parallel Electrode electroluminescent panels; be sure you choose the correct inverter for your electroluminescent material. If you need any help, please feel free to contact us today with any questions you might have.

Pushing the limits of R&D to pioneer the next generation of lighting solutions All of our high bay lights & flood lights use the ICEPIPE heatsink technology to ensure proper cooling that is more efficient than your standard LED fixture. LED high bay, roadway, canopy stadium lighting

Great for under cabinet lighting, retail display case, custom architectural lighting fixtures and signage. Available in widths of 0.4 inches by 16.4-foot lengths [10mm x 5m] White and RGB (Red, Green, Blue) colors are stocked Low voltage DC No mercury or heavy metals No maintenance Adhesive backing Life ~50, 000 hours Can be dimmed No noise No UV UL listed now available

Our flicker-free LED bulbs can be used in many applications from new to retrofitting an existing luminaire making it LED efficient. Working at a voltage of 100-277 AC, these LED bulbs are suitable for many installations Since our bulbs require an airtight fixture they work well in explosion proof and other airtight fixtures such as street, roadway and high bay. You can see tremendous savings by replacing just the bulb instead of a complete luminaire. The 80-Watt bulb has the light output of a 250 Watt metal halide or a 333 high-pressure sodium and costs about one hundred dollars vs a new LED fixture at several hundred dollars. In most traditional luminaires the only required modification is to bypass the ballast. 18W, @ 1, 710lm- Replaces 45W CFL, 135W incandescent, 144W halogen 25W, @ 2, 500lm- Replaces 63W CFL, 188W incandescent, 200W halogen 60W, @ 5, 580lm- Replaces 180W MH, 240W HPS, 480W halogen 80W, @ 8, 000lm- Replaces 250W MH, 333W HPS, 666W halogen

LED backlighting panels were used in the construction of this lightbox display. Premium LED modules, made with Nichia or Cree LEDs, are a UL component, have a 7-year warranty and an L70 life of up to 100, 000-hours or more. Our lower cost Economy modules [without UL} are an excellent value and have a 3-year warranty. 1, 2, and 3 color LED (non-video) modules are available in red, green, blue and white, in several color temperatures. 2 and 3 color modules make possible a range of colors or color temperatures by varying the brightness of each color. For example, if you have a 2 color LED module that contains 3, 200K and 6, 500K LEDs, you can select either of these two color temperatures or any color temperature in-between. 3 color LED modules can have LEDs in color or in any of several shades of white. Our LED modules can be dimmed.

Electroluminescent (EL) sheets and strips are light-weight, flexible lighting. Knema, LLC., offers stock electroluminescent material available in a bluish-white light (when on). Several panel sizes are stocked, custom sizes, shapes, and colors are available on request. Possible uses include signs, cove lighting (architectural lighting), floors, furniture, retail displays, lighted shelves, back-lighting electronic displays, theatrical costumes, emergency lighting, egress and pathway lighting. Thin and flexible Generates minimal heat Can be dimmed No filament to break Lightweight, only 4 ounces per square foot Sizes up to 16.5 x 23.5-inches (A2) Not affected by vibration Does not burn out suddenly Very low power consumption Can be cut Continues to operate, even if punctured Approximately 0.020” thick Electroluminescent (EL) material is offered in two types. One being Parallel Electrode, sometimes called an EL panel. This type of EL material does not have a center line and would be a good source for back-lighting signs and artwork. The second type of EL material is Split Electrode, a long and narrow or long wide electroluminescent strip. The EL strip is available in lengths of up to several hundred feet and has a 1100-inch center scribe line running the length of the strip. Split Electrode material is a good back light source for signs where a small center line will not detract from your graphic or where long length strips are needed as accent or pathway lighting. Whether called foil, strip, panel, film, sheet, or lamp, the electroluminescent products are the same. EL panels are thin (~0.5mm), flexible and weigh about 4 ounces per square foot. The panels we stock are WHITE when on, pink when off. Other colors are available as a special order item, a tooling charge and minimum order quantity will apply. Custom size and shapes are available. We will need a CAD file in the DWG format to quote and manufacture a custom size and shape EL panel. Regarding panel appearance: To make a white panel, manufacturers add a pink florescent dye to blue-green phosphor making the panel appear pink when “off” and bluish white when “on.” EL panels can have an acceptable white appearance when a graphic, printed on white film, is placed on the panel. However; some white areas in a graphic overlay can have a pink cast; this is caused by light reflecting off the graphic back onto the EL panel. EL panels are manufactured with a process known as screen printing which gives a fairly even illuminated surface; It's not perfect, though and may not be appropriate for some optical calibration applications.
