Light Where it Matters the Most
What is Luxor?
Luxor is the flashlight reinvented. What sets Luxor apart from all other flashlights is its ability to focus light from wide angle to narrow spot view without the need for expensive lens systems or any moving parts. The computer controlled Digital Focus System (DFS) delivers perfectly uniform light patterns ideally suited to the human eye's full range of vision. Luxor's light focusing capabilities dramatically enhance your ability to be more aware of your surroundings where your peripheral vision can be fully utilized. No other flashlight offers this much versatility and intelligence.
Digital Focus System:
Having light when you need it and where you need it allows you to be more productive. Most importantly, knowing how long your light will last can mean the difference between life and death. Luxor solves this problem with a Battery Monitoring System (BMS) coupled with an OLED readout. Luxor's computer controlled BMS learns how you're using the flashlight based on your desired brightness and focus levels. It then tells you precisely how many day:hours:minutes of battery life you have remaining before Luxor's batteries go empty and much more...
*Due to continuous product improvements screen shots may differ slightly from actual product.
The intelligent OLED display was derived from another PLX Devices successfully funded Kickstarter project called Legion. The world's most intelligent battery for all of your electronic devices.
Luxor's intelligent algorithms learn how you're using your flashlight and calculates your energy usage at roughly 500 times/second giving you ultra accurate battery metering. Luxor's high contrast OLED display shows you precisely your exact mAh capacity, battery charge percentage, time to charge/discharge in (day:hours:minutes), battery voltage, current in amps, power in watts, battery condition, mode, light output levels, number of charge cycles, and the battery's temperature.
Luxor also employs many additional advanced features such as automatic low power sleep mode, a double buffering graphics processor for seamless OLED transitions and intelligent battery monitoring algorithms to precisely calculate your battery's condition as it degrades over time. A high temperature protection circuit prevents the lithium batteries from ever being overcharged and over drained. Many other batteries on the market are dependent on the actual voltage of the battery to represent the current state of charge. Luxor's intelligent battery metering system is immune to such inaccuracies because it does not use the voltage to determine the current state of charge. A lithium battery's voltage will vary drastically depending on the actual load or power draw from your battery. Luxor, employs a current based method of battery metering coupled with PLX Devices' proprietary algorithms making Luxor's battery monitoring system supremely accurate down to a single mAh. Never be left in the dark about the condition of your flashlight's batteries again.
Design and Function
Luxor uses 7 Cree LEDs delivering up to 710 lumens of light intensity. This is roughly equivalent to the light output of a 53 Watt incandescent light bulb. 1 Cree XTE LED is used for the center beam, 3 Cree MLC LEDs are used for the flood wide angle focus, and 3 Cree MLC LEDs are used for the omni-directional lantern focus.
Digital Focus System (DFS):
The Digital Focus System uses pulse width modulation (PWM) and computerized algorithms to calculate the optimal brightness levels for each of the 7 LEDs in order to deliver 12-270 degrees of Digital Focus range while maintaining outstanding light distribution patterns. The LED controller uses high efficiency solid state transistors capable of adjusting the brightness of the flashlight from 0-100% (0-710 lumens).
Luxor has been optimized to deliver the best all around performance and function. The following are specifications of just the beam performance.
Lithium Polymer Batteries:
Luxor comes with a high density 5000mAh rechargeable lithium polymer battery. The battery can typically be charged up to 1000 times before they need to be replaced. This is equivalent to using roughly 5000 AAA alkaline batteries costing about $4280. Often times, users of alkaline battery powered flashlights throw away their batteries prematurely due to the unknown state of charge. With Luxor's Battery Metering System (BMS) you can avoid this problem by simply reading the state of charge on the integrated OLED display. The lithium battery is user replaceable.
Luxor can be charged from any USB power source. Simply plug in the provided USB retractable cable between Luxor and any USB power source. Charging is automatically activated. Luxor's CPU samples and analyzes the USB port's current output capabilities and accurately displays the time remaining before Luxor becomes fully charged. Luxor knows when the batteries have become fully charged and will deactivate the charging circuitry automatically to prevent the batteries from overcharge and overheating for added safety.
Battery Monitoring System (BMS):
Luxor's integrated computer monitors the amount of current going in and out of the lithium polymer's batteries at a rate of 488 times per second (488Hz). Coupled with a 12 bit analog to digital converter makes for extremely accurate battery metering. Luxor's CPU learns how you use your flashlight by taking into consideration battery voltage, actual battery capacity, total usable battery capacity, number of battery charge cycles, battery temperature, desired light output, and user defined digital focus modes. The data is computed and displayed on the OLED giving you valuable information such as time remaining, time to charge, and much more.
Automatic Consistent Brightness (ACB):
Most flashlights on the market will deliver variable brightness levels depending on the current state of charge of the battery. As a battery is drained, the voltage of the batteries drop. This results in an equally proportional drop in light output levels. Luxor solves this problem by analyzing the current state of the battery's voltage along with other BMS parameters. Luxor's CPU communicates with the solid state LED controller to automatically compensate the output brightness of each LED. Light output stays consistent regardless of the state of charge the battery is in. *ACB works only in non current limiting situations.
Low Power Sleep:
When the power button is depressed, Luxor goes into a low power sleep mode drawing just nano amps of current. This allows you to store Luxor for up to 2 years. This is ideal for emergency situations where your flashlight is not regularly charged and used.
Traditional flashlights use mechanical switches. This out dated technology does not provide much resilency to corrosion and longevity. Mechanical switches rely on large terminals/contacts to give it the capability of carrying large current loads. As these terminals corrode from oxidation and other standard wear, the in-series-resistance of such terminals increases with time. Connections get hot and light output drops from the heat generated from poor mechanical contacts.
Luxor employs digital switches called solid state switches. Solid state switches resist oxidation, deliver very low in-series-resistance, and performance is guaranteed for decades with negligible degradation. Digital switches also have the advantage of reacting to single-tap, double-tap, tap-and-hold, and tapping 2 or more switches simultaneously to activate other functions.
Luxor comes with many rubber components designed to shield against water and moisture.
Luxor is patent pending.

Electronics Manufacturing and Assembly - Manufacturing the electronics requires a fiberglass base board with copper interconnects called a printed circuit board (PCB). Luxor's complex electronics requires that the PCB be manufactured with the tightest of tolerances to ensure reliable electrical connections between the dozens of components to be placed on it. Manufacturing the PCB is just half of the story. Assembling the electronics onto the PCB requires high precision machines to place and solder the tiny components. Finally, x-rays are used to inspect the quality of the solder for any micro cracks and/or any poor electrical connections. Over the past several years, we have established partnerships with strong manufacturers in Asia that can perform such a complicated process. We're very confident in our partners' abilities to manufacture Luxor's electronics with the highest quality standards. Here are some pictures of the machines used to manufacture Luxor's electronics.
Aluminum - Manufacturing Luxor's head and body requires machining. Once the aluminum is in its final shape and form, it will be sanded and polished to create a smooth and shiny luster. Here are some pictures from our manufacturing partner in Asia who will be performing the machining.
Plastic - Manufacturing the plastic components of Luxor requires a process called injection molding. Injection molding is a process of injecting molten material into a cavity. The cavity forms the inverted shape of the part being created. High grade, impact resistant plastic will be used for all of Luxor's plastic parts. Here are some pictures from our manufacturing partner in Asia who will be performing the injection molding for Luxor's plastic components.

Risks and challenges
PLX Devices has been designing and successfully bringing products to market for over 11 years. For this project, our biggest challenge was combining the mechanical, computer, and electrical engineering aspects of the project to make a single product. A project combining all 3 engineering disciplines of this complexity has never been attempted by our team before.
Mechanical Engineering - Our biggest challenge is to ensure that all the aluminum components are manufactured to our exact design specifications. We expect several iterations of samples from our overseas partners to perfect the process. Each round of samples could take as much as 4 weeks which could potentially delay the project. To avoid this, we will need to communicate clearly and frequently with our partners as well as hold them accountable to meet quality standards and deadlines.
Electrical Engineering - We don't expect any significant problems to arise as this has been our area of expertise for over a decade. If a problem were to arise, it would be in the assembly process of the electronics. Small components may not be soldered properly onto the printed circuit board thus creating unreliable electrical connections. This could potentially cause a few weeks of delay. To combat this, our electrical engineers will be working closely with our overseas partners to adhere to our strict quality standards.
Computer Engineering - We also don't expect any significant problems as this is also our area of expertise. If a problem were to arise, it would be in detecting bugs in the software code which could hinder Luxor from fully functioning. To combat this, a simple rewrite of the software code will solve any problems that may arise.
We already have our manufacturing all setup in some of the world's best factories which adhere to internationally recognized quality standards and procedures such as ISO9001, ISO/TS 16949, ISO 14000, TQM, SPC.
The prototypes are finished and we're ready to go into production. We need your help and we hope you'll join us.
