Composite Filter for: Nano 2S

DentLight’s composite filter is custom designed and molded to prevent composite cures during prep and filling before final cures. It is incredibly easy to use:

  • Hold the filter clip above the ledge/rim close to the front of the lamp housing
  • Snap the clip into the rim for a secure fit
  • Use filter flip paddle/tool to flip the filter in and out of the field
  • Orange filter to block blue light
  • Filter has three preset angels/positions to easily get out of the light field
  • Flip flip paddle/tool (autoclavable) prevents any contamination on the filter, light or loupe.

Wire Routing for Nano

Nano uses custom made special Teflon wire that is not only strong and durable but also easy to maneuver into predetermined shapes to conform to the frame/facial contour. Use spiral Wire Wrap to fix the wire on the frame temple.  Angle set the wire coming out of the LED lamp to comply with the contour of your loupe frame

Use Wire Clip to fix the cord on the scrub collar on the back of your neck. Use of protection cord will help extend the lifetime of your cord as illustrated below. (a) Position Battery Pack with the Battery Pouch/Clip on the waist or belt of your scrub. (b) Always use Protection/Extension Cord when battery is placed in your scrub pocket.

Mounting Tips for: Nano 2S

Assemble the loupe light to your loupes using one of the interchangeable mounting adapters:

  • For flat glass frames and safety goggles, use the standard Universal/L combo adapter to clip on to the frame center.  Route wire by bending the Teflon wire 90 degrees at both the center of the frame and temple/frame junction. Use Wire Wrap to secure wire on the Frame Temple.

  • For 1) Orascoptic Rudy; 2) Zeiss EyeMag pro; 3) Orascoptic Titanium; 4) Surgitel Titanium,  first remove glue-on logo plate at the center of the frame, then screw on L-adapter at the center of the frame.

  • For Flip-up loupes (e.g. iZoom, Sheervision, Surgitel, PeriOptix), use U-adapter and slide to the middle of the flip-up bar.

  • For DFV Yoeman, Nike, Surgitel Oakley and other curved frames, use Y-adapter to mount at the center of the frame with optimized cascading articulating arms.

Why DentLight?


AGD Impact, December, 2012

January 14, 2013

I love my soft tissue diode laser (Picasso AMD/Dentsply) and I love my eyes. In order to protect your eyes (and those of your assistant and patient as well) you must wear a filter. That often entails using something over or behind your present loupe system or maybe even buying another set of filtered loupes just for use with laser procedures. DentLight has introduced their clip-on ocular filter called SafeLoupe  that will easily clip on to the most popular brandsRead more


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.
    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.
weight lights1
    Second, the light intensity and pattern uniformity outperform most of the headlights making the visual acuity of teeth much better. Most other lights have internal pattern structure within the light beam making the intensity pattern uneven and distorting the field of view.
pattern comparison
    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.

    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.

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 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 in four generations with each one performing better than the previous one while maintaining our pricing throughout the improvements. This is different from larger companies which outsource most of the development or smaller companies which rely on standard off-the-shelf products with no control over materials. We pride ourselves in standing behind our products over the past 9 years serving dental professionals to their highest standards.

How long does the battery run?

Battery performance (hours)

Nano 2S Nano 2C
Level I 24 10
Level II 14 6
Level III 10 4.5
With your choice of the industries' longest running battery or smallest battery, you can work all day or half a day without worrying about your battery at the highest intensity levels for your eye wear. Nano battery has the option of direct plug in from charging cord to power up the unit as corded light for non-interrupted run.

How long will the wire/connector last?

    Lamp wire and connector are the most stressed component in the headlamp use.
    Nano 2S/2C are the fourth generation lights designed by DentLight with further improved custom nano-engineered teflon wire and custom molded reinforced connector to address the challenging problem.
    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. The smaller size not only reduces stress but also improves the durability and handling from clinical wear and tear.
Nano wire comparison
    Combined with custom soldered and molded connector with a reinforced jacket, the new generation 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 it 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.
    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.

What is the beam size from Nano?

Nano 2S and 2C have a focused beam size of 2.8 inches at 14 inch distance (30% larger than Nano 1.0). 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.

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.

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

Yes. 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. 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.

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 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.
    In the low digital power setting, the lights will never get hot. In the highest digital power setting, the heat sink will get hot but other areas with easy access to finger, nose and forehead will never get hot. So use the light according to our instruction, it is safe to operate all the times.

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
    If you are comparing with other lower cost headlights, 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 "What is the difference between Dentlight's headlights and other brands?" for further comparisons.

Can you weigh the advantadges of Headlights with Overhead Operating Lights?

Overhead Operating Lights have been the industry standards for ages. The advantadges of the DentLight headlights vs a quality Overhead are:
  • Much brighter: 2 to 4x more concentrated light which is crucial in loupe procedures in efficiency and doing better quality work 
  • Portable with minimum weight (basically you feel no burden with you)
  • Direct line-of-sight with no shadows (ideal for teeth extraction)
  • Skylight color easing color matching
  • Easy composite settings
  • Does not taken any chair/counter space
  • No more bulb replacement
  • As low as a fifth of the cost

How much light is enough for me?

It is primarily determined by the magnification times of your loupes. When you double the magnifications, you need to quadruple the amount of light to see under the same contrast/clarity. Secondarily, eye sensitivity of each person is different and even the same person is different at different ages. It never hurts to have sufficient power if you can while you have the freedom of adjusting to your like. DentLight's solutions deliver sufficient light to cover users of all ages, all magnifications and all loupes.

Do I still need to replace light bulb?

Fiber optic headlight uses Xenon or Halogen lamp with lifetimes in the range of 500-1000 hours. DentLight's LED headlights use high quality and high power LED lamp integrated with advanced heat sink and heat protection systems with lifetimes rated above 50,000 hours. Under normal use conditions with good product care, you would need a very long time to replace the lamp (maybe your career).

What is a composite filter and How is DentLight’s different?

Composite filter helps normal restorative procedures in preventing composite cures during prep and filling before final cures. The filter first needs to have sufficient isolation of blue wavelength light to prevent composite cured while applying the adhesive or packing the box. Second is convenience of use in that it is easy to move in and out of filtering position for normal and composite procedures without fighting with loupes lenses (e.g. rotating filter). Third is contamination when the gloves do not contaminate the loupe and light. DentLight's composite filter is custom designed and molded to achieve all the above characteristics. It comes with three parts assembled:
  • Snap-on clip to headlight so that the filter can be taken in or out of the light in a snap
  • Orange filter to block blue light
  • Filter flip tool that can easily touch set filter into preset angels/positions while preventing any contamination on the filter, light or loupe.
The Filter flip tool can be easily slide out and autoclaved for disinfection. No more fighting with the filter loose, screw, bump with lens and contamination.

How important is the weight of a headlight?

The weight of a headlight is very important since your head and nose bear the weight of the light all the time up to several hours in a procedure. However, it does not mean that the smaller the better since without sufficient optical illumination you will not have the detail and clarity in doing your job. Beam spread is also an important parameter to minimize glare to patient eyes. Therefore, the ideal combination of weight and power is the target of an optimum light - Nano. This is why we designed our optoelectronics to deliver the most power per grams and the best beam spread of any headlights on the market. Nano delivers 20-50% more power than similar lights in its class while having digitally adjustable power levels to get the most personal comfort in precision. Additionally, once the headlight's weight is below 10 grams, you would not notice much differences in wearing it given that the weight will be dominated by loupes typically 4-8 times of that weight. Nano is optimized for the weight and power for most illumination applications. Together with an iPod size battery pack, which is at least half the size of any competitors,  you will feel the freedom and power in concentrating in your job.

Why do I need a light?

With magnification loupes becoming more of a standard in restorative procedures, there is an ever increasing demand for better oral cavity illumination due to reduced optical aperture from the magnification optics. Overhead operating light and fiber optic headlight have been the standard for normal procedures until the past three years when the advancement of LEDs are starting to replace normal halogen, Xenon and plasma lighting in the same fashion of curing light. LED headlights make it possible to become smaller, brighter, lighter, portable and much more economic in scale of starting and operating a dental office. As a result, they are replacing the traditional fiber optic headlight and overhead operating light as championed by a number of industry leaders. More and more dentists are starting a practice ground up or transforming their offices leveraging on the new LED technology. The ideal combination of a good LED light and appropriate magnification speeds up procedures, improve quality of restorations and helping find canal. Just like the old saying: Seeing is Believing. DentLight offers the best combination of the both world in quality and economy. With the suite of solutions we offer, you can always find the comfort of what you need with the assurances of quality support behind you all the times.

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 for general illumination with magnification
  • iZoom for advanced illumination and oral exam where field of view (e.g. full oral cavity) and power are desired (e.g high magnification)
  • Extreme for oral surgeons, endodontists and high power magnification users of above 4
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. Additionally, iZoom offers variable beam and optional hot-swappable Violet LED lamp for composite viewing and removal in addition to other medical exam capabilities that no other dental lights offer on the market. We offer four mounting adapters that fit on all loupe brands and frames.

Where can I purchase DentLight’s products?

DentLight sells its products through most dental specialty distributors and dealers in the US. We exhibit our products at a number of regional and major trade shows. We are expanding internationally in Europe and Asia. Please check on where-to-buy for individual products. Service is offered through our manufacturing facility in Plano, TX.

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 model while maintaining the price: 1. 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. 2. New optics to expand the beam size 30% for optimum full oral cavity uniform illumination. 3. 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.

A product that I would not practice without!

After researching headlights  at GNYDM 2011 I purchased the Nano light. My criteria for purchase revolved around comfort, quality of the light beam, as well as the quality of the product. It is now two years later and i am as happy with the purchase today, as I was the day it was purchased. Simply put, I see clearer, so my work is better. I have had two encounters with DentLight’s customer support and each time it has been exemplary. Thank you for a product that I would not practice without!
