Why do I need Touchless?

With the fast improvements in technologies, dental headlights are no longer for surgeons only but becoming more popular with general dental procedures for dentists, hygienists and assistants to improve on efficiency and profitability.  One of the major challenges coming with everyday uses is infection control when adjusting the battery from on and off. Nano 2S Touchless meets this challenge using the recent technology in capacitive touch sensor which actives and deactivates the light with proximity capacitance changes from the skin with either palm or finger even with glove on and coat covered.  The touchless feel is incredible making the users' life a whole lot easier and clean.

How long will the wire/connector last?

    Lamp wire and connector are the most stressed component in the headlamp use. Beyond personal care and wire management, the engineering designs of wire and connector are directly tied to the professional lifetime of the product.
    Nano 2S/2C are the fourth generation lights designed by DentLight. Material selection, patent-pending engineering and simplicity are the keys to the product design success. Rather than complicating the design with connection on the lamp side which introduces more failure point, we reduce the stress by shrinking the wire size to 1/4 of normal wire using nano-engineered teflon wire with a patent-pending reinforced connector on the battery side.
    The unique mechanical properties of the teflon materials used in the wire offer ten times the flexural strength as well as impact, cut-through and abrasion resistance than regular PE wires. This enables us to reduce the lamp wire diameter from 3mm to 1.5mm thus shrinking the wire volume to 1/4 of normal wires. The smaller size not only reduces stress but also improves the durability and handling from clinical wear and tear.
    Combined with custom soldered and molded connector with a reinforced jacket, the new generation Nano releases represent the most advanced technology design for professional medical illumination applications making the wire and connector so much easier to use and manage that the wire feels like "invisible" to most users.
    Additionally, the new release kits come with custom protection cord to further extend the lifetime of your lamp in a harsh clinical environment with expected service life 2-3x longer than normal headlamp.
    Furthermore, Nano 2S/2C are designed with modular construction for easy in-house service replacement, which no other manufacturers offer. This will reduce the cost of ownership of the product for a long long time of profit generation in the clinics.

What is a protection cord and why is it needed?

DentLight's headlight all have lifetime warranty on the LEDs built-in the lamp. The lamp cord coming with the light is made with the strongest custom wire and custom reinforced connector. To extend the service time of the lamp cord in a heavy duty professional clinic, we designed and custom made protection cord. As with all lights and battery, the junction from lamp to battery is where the most stress and pressure applied. The lamp can operate directly without protection cord, which is an insurance to the original lamp cord. This will ensure the minimum service charge  and prevent any downtime in case of unintentional damages or failure.

Which headlight works best for me?

Headlight is a step up from normal lighting solutions in that it offers flexibility and direct line-of-sight illumination with no blind spot. Depending on personal eye sensitivity, each person could be somewhat different in the preference of his/her lighting solution depending on his/her standard eye wear (for e.g., prescription glasses, safety goggle, face shield etc) and magnification loupes (brand names, magnification, optics and frame style). In general , sufficient lighting is required to achieve the detail and clarity in order to better handle operating procedures. DentLight's solutions offer:
  • Nano 2S and 2C for general illumination with magnification
  • Xtreme for oral surgeons, endodontists and high power magnification users who requires more intensity
All of our solutions have the best characteristics in their class in weight, size, digital functions, and a full suite of accessaries that significantly ease the integration and operation of the lights. We offer five mounting adapters that fit on all loupe brands and frames.

What makes Nano lights the most comfortable lights?

Given that headlights are worn by clinicians all day long, the comfort level directly impacts the practice efficiency. Factors affecting the comfort levels include the weight and size of LED lamp, wire/cord, battery as well as the ease of activating and deactivating the light and composite filter. Additionally, the optical power, color, and beam quality/uniformity will significantly impact the visual comfort and procedure accuracy. Nano lights delivers the ideal combination of weight, size and optical beam. They not only offer the smallest and light weight LED lamps, but most importantly the smallest, lightest and easiest managing wire and battery pack. Combined with the superior quality optical power and beam delivered, users are guaranteed the most comfort and quality of any loupe lights as explained in more technical details in "How is DentLight different from other headlights".

Why should I buy your lights as compared to other cheaper lights?

    DentLight's headlights are half the cost of similar quality products with FDA certifications.
    If you are comparing with LED lights in consumer stores that cost less than $100, the differences are:
  • 4x to 8x more optical power with much focused beam (light you can not live with loupes)
  • Easy mounting to your loupes and eye wear
  • Integrated small rechargeable battery packs (you never need to worry about buying AA every day, the cost of which in a year will be more than the light)
  • Add on accessories to enable your professional job
  • Full service and support
    One of the major concerns over the loupe light is safety as incidents have happened including fire hazard from burning battery and skin burn from lamp high temperature as illustrated from image below.
lumadentbatteryfire-dentaltown DentLight offers the most trustworthy and quality products as proven by clinicians and we stand fully behind our products as compared to some other companies without any FDA certification or independent validations on quality or performance. See How is Dentlight different from other headlights? for further comparisons.

Does DentLight’s headlights get hot?

    LED headlights generate light through electrical current. The conversion from electrical power to optical power is close to quantum limit meaning that it is much more efficient than normal light bulb (about 80% energy saving). The part of electricity that did not convert to light dumps into heat sink of the headlight and increases temperatures.
    Every high power headlight will generate some heat and become hot over time. The higher the power, the more heat. Depending on the size of the light, the heat will transfer into local temperatures or hot temperatures. The smaller the light, the hotter it gets with the same amount of electrical driving current and same surface areas.
    DentLight's headlights are designed to optimize the heat transfer at their individual design size and engineering target. There is one main difference between our lights and other competitors lights in that we isolate heat for safe operations.
    The new generation release (8/2015) significantly improved the heat dissipation and management resulting a super cool lamp even at the high power setting that the user will never feel their finger or skin hot burnt upon touching the lamp as is the case with other lights.

Can I leave the battery on the charger all the time?

Yes. You are assured of safety with our smart battery. One of the major concerns over the loupe light is safety as incidents have happened including fire hazard from burning battery while charging overnight as illustrated from the image below. lumadentbatteryfire-dentaltown Dentlight's battery pack integrates smart charging electronics that automatically shuts down the current upon full charge and safely charges the battery at low battery voltage without overheating. Our battery pack represents the most advanced Li battery technology (represented by iPhone, iPad of today's world) and the most advanced integrated recharging circuits.  

How is Dentlight different from other headlights?

    Nano 2S and 2C lights are our fourth generation lights released in 2014 optimized to the engineering extreme of performance and quality. Recent release Nano 2S Touchless in 2015 further extends user interface to a whole different level for the most comfort and safety from contamination perspectives.
    First Nano light is a lot smaller and easier to use than other similar lights on the market. Weighing 6 grams on the lamp and 17 grams total with the cord, it is the lightest and most comfortable loupe light on the market by a huge margin.

    Third, Nano battery is designed with a built-in microcontroller to regulate battery, LED power and smart audible/display indications. Most other competitors use low level analog battery with mechanical buttons/turn knobs. The more advanced digital design used in Nano battery makes it not only a lot easier to use and clean but also much more robust and reliable with no moving parts. It also makes it possible to become at least 1/3 smaller but longer running for up to 24 hours. Nano 2S Touchless battery is a whole new level with easy activation of the light through proximity touch sensor even through gowns and gloves using the back of your palm or lower arm.

    Last, the Nano 2S/2C lights use nano-engineered wire that is less than half of the size of anything out there while having ten times the mechanical flexural strength. The patent-pending wire and wire connection makes your daily routine much more comfortable and user friendly as the light becomes invisible in your practice..
    Dentlight also has the most complete dental headlight offerings of any companies beyond the small light offering of Nano.
    Xtreme delivers medium-to-high end optical power of up to 100,000 lux with uniform and variable beam size adjustment ideal for surgeons, endodontists and professionals who require the most power at even higher magnification.

Will Nano 2S/2C fit on any loupes, glasses or eyewear?

Yes. We offer a suite of five standard mounting adapters and a few more adapters for custom loupes. The adapters suit a broad range of personal preferences including removable and semi-permanent more secure attachment.

Is it possible to operate Nano handsfree?

    Yes. Nano 2S and 2C come in with two special features that enable handsfree operation:
    1. Battery pack with large ON/OFF key that only requires a simple knock from the elbow to turn on and off the light. This feature avoids contamination on the battery.
    2. Composite filter flip-up paddle that avoids contamination of filter/light.
    Furthermore, if you want the most convenient hands free operation, you may upgrade to the new release Nano 2S Touchless which uses an optimized capacitance activated sensor to help you activate the light through your pocket or gown with a simple close proximity placement of your wrist or forearm.

How durable are the Nano 2S/2C lights?

    When it comes to engineering design, DentLight is vertically integrated in the design and implementation of all components. We do not cut corners and use cheap components for professional use. We ensure the highest quality and design in our products to their engineering extreme in form-factor, functionality, ease of use and durability on each component of LED, wire/connector, SMT, housing, and battery.
    Headlamp itself consists of LED on its mounting base and optical assembly. Nano headlamp is shock proof in durability.
    Unlike other headlights using off-the-shelf wire and connectors, Nano 2S/2C uses custom nano-engineered wire and patent-pending reinforced connectors unmatched on the market in comfort, strength and quality. We are proud to achieve the engineering feat that our competitors can only look up to.
    Our products have evolved through four generations in 6 years with each one performing better than the previous one while maintaining our pricing throughout the improvements. This is different from other companies who outsource their development or rely on standard off-the-shelf parts that mostly does not meet the harsh clinical environment.
    Furthermore, our modular design makes it easy for our service department to repair any components in the product including replacement of wires, connectors, lenses, and SMT components typically in just a couple of days.
    We pride ourselves in standing behind our products over the past 10 years serving dental professionals to their highest standards.

What are the differences between Nano 2S/2C and our previous Nano lights?

Nano 2S and 2C are our newest models replacing the previous Nano 1.0 and Nano 2.0. Three areas have been significantly improved over the previous models while maintaining the price:
  • Upgraded the cord and connector to nano-engineered wire and patent-pending reinforced 135 degree angle connector - the industry's thinnest and most durable cord with custom molded super strong connector.
  • New optics to expand the beam size by 50% for optimum full oral cavity uniform illumination.
  • Double (2C) and quadruple (2S) the running time of the batteries with improved interface, smart alarm and set-and-forget power settings.
Nano 2S and 2C battery packs are compatible with previous generations.

What are the color temperature and beam size? Can you describe the optical uniformity?

DentLight's headlight is designed to operate at a “Natural
 Light” color temperature of 5500 Kelvin, which simulates the North 
Daylight. Nano 2S and 2C have a focused beam size of 3.0 inches at 14 inch distance. Since men's average oral cavity size is between 2 and 2.4 inches while women's are between 1.8 and 2.2 inches, the optimized beam size will illuminate the full oral cavity at full open position while reducing spill over light to the patient's eye. Our custom optics enables uniform illumination within the field of view of regular loupes unlike most other headlights with uneven patterns with the light beam. This is particularly important in shade matching to ensure the best possible color matching with no visual mistakes.
