  2. WHO WE ARE WHO WE ARE Founded in 2010 by a group of professional engineers with • extensive background in optoelectronics – Composed of experts in material science, thermal management, power driver electronics and optical design – Designed by engineering teams in Los Angeles, Shenzhen and T D i d b i i i L A l Sh h d T k okyo and d manufactured in Shenzhen – Manufacturing facility capable of producing over 1.2 million 4ft T8 equivalents annually equivalents annually We aim for the highest performance at modest prices, we utilize • talent from around the world to achieve the best possible performance and produce the products where the costs can be p p p driven down Currently OEM manufacturing for LG and OSRAM for certain LED • product lines p

  3. WHAT SETS US APART WHAT SETS US APART • We work with the best LED suppliers, primarily utilizing our pp p y g solid relationships with LG Innotek and Samsung LED • We design products ground up from the demand side, all our designs cater to the specific needs of the lighting market designs cater to the specific needs of the lighting market • Our products are aimed towards the US and European markets where labor costs make up a substantial proportion of installation costs of installation costs • Our primary objective is long term viability, reliability comes first and foremost • Energy savings are a must, our minimum performance metric is over 100lm/w @ 85CRI across all our product lines and at present, are at the top of the class for each category on DLC p p g y

  4. CURRENT T8 FLUORESCENT LAMPS CURRENT T8 FLUORESCENT LAMPS • T8 fluorescent lamps have the following metrics and issues: p g – 83~88lm/w typical design lamp efficacy at 25°C ambient temperature – 70~85Ra typical CRI, lower efficacy at higher CRI figures – 20K~25K hour 50% (L50) survival life, lower when cycling more often 20K 25K hour 50% (L50) survival life lower when cycling more often – Suffer fromchromatic shift over time, turning pinkish red to purple – Source of mercury contamination from low recycling levels in the US – Substantial lumen loss from LDD (Luminaire Dirt Depreciation) within months due to dust accumulation above lamps – Lower lux levels due to diffuse light spread, lamps also physically block substantial portions of the light reflected off the reflector

  5. CURRENT T8 FLUORESCENT FIXTURES CURRENT T8 FLUORESCENT FIXTURES • Common T8 fluorescent fixture performance metrics: p – 61lm/w, 70Ra - 2x4 parabolic fixture – Lithonia 2PM3N 2 lamp – 73lm/w, 70Ra – 2x4 prismatic fixture – Lithonia 2GT8 2 lamp – 61lm/w, 70Ra – high bay fixture – Lithonia IBZ632 6 lamp 61lm/w 70Ra high bay fixture Lithonia IBZ632 6 lamp – 73lm/w, 80Ra – high bay fixture – Lithonia FGB24 6 lamp – 48lm/w, 80Ra – vaportight fixture – Lithonia VAP 232 2 lamp – 64lm/w, 70Ra – vaportight fixture – Lithonia DMW 232 2 lamp – 77lm/w, 70Ra – low bay aisle fixture – Lithonia AF10 232 2 lamp

  6. T8 LED LAMPS T8 LED LAMPS • T8 LED performance metrics from other suppliers: p pp – 100lm/w, 85Ra, 50K L70, 50K L50 MTBF – OSRAM ULTRA LED T8 – 102lm/w, 83Ra, 60K L70, 50K L50 MTBF – Philips LEDtube T8 – 104lm/w, 83Ra, 50K L70, 50K L50 MTBF – DLC Average 104lm/w 83Ra 50K L70 50K L50 MTBF DLC Average * For 5000K CCT lamps – • Above Lights LED performance metrics: – 125lm/w, 88Ra, 80K L70, 50K L10 MTBF – OBS-416 – Diffuse Lens – 135lm/w, 88Ra, 80K L70, 50K L10 MTBF – OBS-416 – Clear Lens / , , , * For 5000K CCT lamps –

  7. OUR ADVANTAGES - I OUR ADVANTAGES I • Use of best LED components p – LG Innotek – Above Lights is a Tier 1 Customer – Samsung LED – Above Lights is a Tier 1 Customer • Allows us to source the best binned components from the aforementioned suppliers • Allows us to source the best binned components from the aforementioned suppliers • No low quality Taiwanese or Chinese LEDs utilized • Better performance than Nichia and CREE at better price points • High color temperature consistency, ±100K within each ANSI standard CCT • Chip efficacies of 170-180lm/w from obtaining best bins • Quality PCB materials – Use of Class 2 PCB for higher reliability Use of Class 2 PCB for higher reliability • Use of pure polycarbonate resin for optical assemblies – All other suppliers use recycled PC resin during production to cut costs

  8. OUR ADVANTAGES - II OUR ADVANTAGES II • Ultra low drive currents – 16w LED tubes utilize LED drive current of just 38mA • Reduces heat dissipation per chip at under 0.15w per package – 5630 PLCC package typically designed to run at 150mA 5630 PLCC package typically designed to run at 150mA • 5630 PLCC package designed to run at nearly 0.5w per package • Ultra low lumen depreciation relative to actual LM-80 results • Low chromaticity shift due to lower operating temperatures • Optimal thermal management – PCBs mounted with thermal adhesive onto aluminum heatsinks • Less thermal stress on solder joints due to lower operating temperatures when • Less thermal stress on solder joints due to lower operating temperatures when power cycling, a very common failure mode for power drivers and LEDs • Solid aluminum heatsink provides tube rigidity and ideal thermal dissipation

  9. OUR ADVANTAGES - III OUR ADVANTAGES III • Optimal thermal management p g – Substantially larger power driver circuitry footprint • Reduces heat load to heat sensitive IC components • Minimizes heat to capacitors, yet another common failure mode for power drivers p , y p

  10. OUR ADVANTAGES - IV OUR ADVANTAGES IV • Better power driver components and design p p g – Use of Nichicon – Japanese made capacitors for substantially longer life – Optimized power driver design reduces capacitor loads and allows for smoother current output and lower ripple amplitudes smoother current output and lower ripple amplitudes • Driver design reduces electrolyte loss within capacitor, yields L10 MTBF of over 57K hours and L50 MTBF of 133K hours – No detectable flicker, lowest in its class , – High performance metrics • 90% power conversion efficiency Highest in its class for UL Class 2 low voltage drivers – Constant current 41.4v DC output for optimal efficiency – Utilizes an improved version of the single switch fly-back topology – • 0.992 PF , 13% THD at 120vAC operation • 0.920 PF , 13% THD at 277vAC operation
