3 Clean Lighting Solutions with LEP Introducing (LEP) Light Emitting Plasma, an innovative solution designed to bring clean, natural lighting to a whole new level. This patented technology, developed by LUXIM, is a high intensity light source that offers bright, full-spectrum illumination in an energy saving and low maintenance package. LEP is used in large scale, high lumen applications, and is ideal for municipal, industrial, stadium, and street & area lighting. Popular Applications High Bay Heavy Industrial Street Parking & Area Top 5 Reasons to use LEP Superior Light Distribution: Create optimal light distribution from a single, directional point source Natural Illumination: Enchance visibility from a full spectrum plasma arc (up to 95 CRI) Uncompromised Energy Savings: Reduce energy usage by 50% without sacrificing brightness levels Worry Free Reliability: Eliminate failure modes and lumen degradation found in most lighting Seamless Controls Integration: Connect to any lighting controls via built in control gear 1

4 Advancing Clean Lighting Technology with LEP Superior Light Distribution The LEP emitter is constructed of a small electrode-less quartz lamp encased by a ceramic resonator. This novel construction emits light, from a small area, in a forward direction into a lambertian pattern. The point source like characteristic provides many advantages in a luminaire s optical performance. A smaller source reduces the amount of optics needed to achieve the required level of glare cutoff and illumination, while ensuring 2 excellent uniformity, by design.

5 Full Spectrum, Natural Illumination EFFICIENCY LEP Luminaires can achieve greater than 90% optical efficiency in most applications In addition, the directionality feature significantly improves luminaire efficiency. Since all of the light is already directed toward the area needing illumination, there are no optical losses from light going in the wrong direction. In most applications, LEP luminaires can achieve greater than 90% optical efficiency into the desired light distribution. 460W HPS 280W LEP Natural Illumination LEP s plasma arc directly emits a full-spectrum white light without the need for a secondary phosphor conversion like in LED or Induction sources. The natural illumination generated from the LEP source greatly enhances visibility and color appearance with a CRI up to 95. The full-spectrum signature also provides increased mesopic/scoptopic illuminance (with S-P ratio of 2.4) which greatly enchances nighttime visibility HPS (400W) 460W HPS 280W LEP Benefit LAMP LUMENS 50,000 23,000 Fixture Efficiency 65% 85% directional source FIXTURE LUMENS 32,500 19,465 Light Loss Factor 75%r 80% low lumens degradation MEAN FIXTURE LUMENS 24,375 15,572 Application Efficiency 48% 82% optical control ROAD LUMENS 11,700 12,769 Application Efficiency: LEP s directional point source allows luminaire designs to maximize the amount of useful light for a target illumination area eliminating wasted light in the form of glare and light pollution. at the time of day when street and outdoor lights are needed.

6 Lower Maintenance Costs Worry-Free Reliability The unique construction of the LEP source and solid state driver eliminates all failure modes of traditional lighting. LEP lamps do not display electrode failures or wall darkering that plague metal halide and HPS lamps. The solid state RF generator is a rugged, semiconductor device made to withstand extended, continuous use. An LEP system for general lighting applications is rated for 70% lumen maintenance (L70) at 50,000 hours. It is important to note that unlike typical HID light sources, LEP sources do not need to be de-rated for the length of operating cycles. In comparison, a typical 400W metal halide lamp can be expected to last 18,000 hours with a 50% survival rate. Uncompromised Energy Savings Energy savings using LEP luminaires comes from a combination of source and application efficiency. Its lifetime is de-rated by as much as 25% for lamp orientation and up to 50% for short operating cycles. LEP does not have these limitations - greatly enhancing its reliability and resulting in lower maintenance costs. LEP s source efficacy, lumens created per watt consumed, is automatically 15-20% higher than an HID source since none of the power is wasted in heating electrodes. Plasma source efficacy ranges from LPW at operating temperatures. On the applications front, LEP sources can be utilized more effectively than HID, induction or LED because of its directionality and size. The directional source prevents light from being trapped inside a luminaire. Point source optics effectively maps the source to the illuminated area preventing unwanted light spill (a source for glare and light-pollution).

7 Seamless Controls Integration The intelligent solid-state driver and an emitter configuration able to react quickly make LEP the only high intensity source that can be dimmed down to 20% of light output, in just a matter of seconds, with both analog and digital controls. Not only that, but dimming actually increases the longevity of the LEP source and the drive electronics. This capability creates an enormous opportunity for reducing energy consumption and operating costs when combined with the use of dimmers, and occupancy or daylight sensors. The LEP driver has many built in functionalities including: > Direct 1-10V input for dimming > Direct low voltage input control by occupancy sensors > Serial interface for digital controls (can interface to DALI and other controls protocols) > Logging of operating parameters including temperature, voltage, current and other diagnostics DC V in DC Ground RF Driver Cable Emitter Low voltage input Signal ground 1-10DV Dimming Rx Serial out Tx Serial in +5V CONTROLS INPUTS LEP System Overview; Built-in control gear compatible with analog and digital lighting controls Analog Dimmer Lighting Network Wireless Controls Motion & Daylight Sensor Unlike traditional HID, dimming with LEP actually increases the longevity of the source and the drive electronics. 5

8 The Science Behind LEP LUXIM s novel plasma lighting architecture consists of two primary parts: > Emitter: A lamp embedded in a ceramic resonator > Radio Frequency (RF) Driver: Both a solid-state amplifier andmicro-controller A radio-frequency signal is generated by the solid-state RF driver and is then guided into the ceramic resonator through a low loss coaxial cable. The structure of the resonator concentrates the RFfield delivering energy to the fully-sealed lamp without electrodes and filaments. The highly concentrated electric field ionizes the gasses and vaporizes the halides in the lamp - creating a plasma state at its center - resulting in an intense source of white light. Inside the back of the lamp, a diffuse yet highly reflective material is used to reflect all of this light in a forward direction. The color of the light is tailored by the fill chemistry inside the lamp to provide a naturally white and high color rendering light Lamp Ceramic Resonator or Puck Power Amplifier The brilliance of the LEP architecture lies in its simplicity. The principal idea is to energize a plasma arc, without filaments or electrodes, and thereby eliminate all failure modes and inefficiencies of an HID lamp. Step 1 An RF circuit is established by connecting an RF power amplifier to a ceramic resonator known as the puck. In the center of the puck is a sealed quartz lamp that contains materials consistent with metal halide lamps. Step 2 The puck, driven by the power amplifier, creates a standing wave confined within its walls. The electric field is strongest at the center of the lamp which first ionizes the gasses creating a glow. Step 3 The ionized gas in turn heats up and evaporates the metal halide materials forming an intense plasma column within the lamp. This plasma column is centered within the quartz envelope and radiates light very efficiently. By Design A single LEP lamp, the size of a tic-tac, can replace 6 a large HID lamp or 200 high power LED s.

LEP vs. LED While LEP is a category of solid state lighting, it is not an LED. The main difference being the use of the solid state device; LEP uses the device to generate RF energy which powers the plasma light source LED uses the device itself for light generation. Some of the similarities include the directionality of the light output, component reliability, and control systems integration. The main difference between the two Is performance - LEP provides higher lumen density (200X greater), and a full color spectrum without phosphor conversion resulting in superior performance in higher lumen applications. LEP vs. HID LEP s innovation over HID light sources is the removal of electrodes and use of solid state electronics, which results in better source efficacy, application efficiency, and reliability. Powering a lamp without electrodes in a compact resonator allows a completely sealed and more robust quartz lamp, a directional beam pattern to improve optical efficiency, and the ability to dim without impacting lamp life. Similar to HID, LEP sources have the ability to scale to high lumen packages easily without the need of multiple sources. Design Tip Use LEP for High Lumen Applications (10,000+ Lumens); Use LED or HID for Mid and Low Lumen Applications. 7

The existing 400W metal halide lighting gave the facility a poorly illuminated appearance and was costly to operate BEFORE and maintain. The school s Facilities Director wanted the gym (which operated 15 hours/day) to be an attractive venue for its teams and decided an LEP solution would address all of the school s needs. Solution: H400 highbay luminaire (using STA LEP system, 280W) to replace 470W Metal-Halide highbay.

11 LEP in Action Outdoor Case Study Location: Scottsburg Indiana (US I-31 and IN-56) Application: Street and Roadway When the City of Scottsburg decided to upgrade its lighting from High Pressure Sodium, they found that LED solutions were too costly for their budget and would not provide the amount of light needed to light their streets. They became interested in an LEP solution when they found out it would allow them to reduce the number of luminaires by 30% to 50% - while still maintaining existing light levels. Straylight Technologies, an LEP lighting manufacturer, helped the City upgrade 600 street and roadway luminaires. Solution: Tesla II Luminaire (using STA-41-01, 280W) to replace 460W High Pressure Sodium with 30% fewer fixtures. Results > Reduced the number of fixtures from 600 to 420 while maintaining brightness and safety levels > 60% energy savings compared to existing HPS solution > Greatly reduced energy consumption and maintenance resulting in payback of 1.5 years» More than $200 annual savings on energy costs per fixture BEFORE» Reduced lamp replacement from 4 to 11 year cycles > Improved the quality of light from yellow to white light with 2.4X better night time visibility > Dark sky compliant with improved uniformity > Reduced the environmental footprint by 558 tons of CO2 emitted per year AFTER Parameter Units Existing LEP Savings Case Details Average Fixture Power Watts Number of Fixtures # Daily Usage Hours Replacement Cycle Years Operating Costs Electricity consumption kw-hr 1,242, , ,800 Energy Cost $/Yr $161,460 $68,796 $92,664 Maintenance Cost $/Yr $18,000 $4,536 $13,464 Total Operating Cost $/Yr $179,460 $73,332 $106,128 Payback Yrs Environmental Impact Emissions Carbon Dioxide Emissions Tons/Yr
