Zeon Discovery Portable LED Headlight


Zeon Discovery combines exceptional illumination with all-day comfort and portability.

Described by Orascoptic as its most powerful light ever, Zeon Discovery delivers 3 levels of brightness and up to 7000 foot candles of light. The focused beam of white light enhances overall visualization and depth of field. The ultra-lightweight headlamp is designed for allday comfort, and the portable design enables complete station-to-station mobility.

The lithium-ion battery pack with push-button power and light-intensity controls is designed for all-day use. A battery capacity monitor signals low run time and a charger doubles as a power supply.

Flip-up or fixed-loupe systems have long been recommended as a means of providing more choices in power of magnification, working distance, field of view, depth of field, and working angulation. 1 Zeon Discovery is designed to attach to all flip-up and through-the-lens loupe configurations. Each headlight comes with a removable filter that prevents premature composite curing.

Illumination and Dispersion

Orascoptic states that LED technology delivers superior brightness, sharpness, and field depth while coaxial mounting eliminates shadows. Of the 9 dentists who evaluated the Zeon Discovery, 5 rated illumination (brightness) as excellent, 3 rated it as very good, and 1 rated it as good. Comments ranged from “average for battery-powered light” to “very bright,” “excellent,” “medium is plenty high,” and “nice and bright when on high.” An Oxnard, CA dentist noted that “3 settings offer a good choice.”

The evaluators rated spotlight quality in terms of light dispersion/focus—3 as excellent, 5 as very good, and 1 as good. Two dentists “liked the flip-down shield for composites” and a periodontist reported “good focus in the center of the light path but very weak in the fringe areas.” A general dentist in practice for 12 years “was a little concerned when the spotlight was more square than round, but it illuminated my field of view quite well.” One evaluator commented on the “nice wide beam” and another “liked the nice focused working area as opposed to dispersed light.”

Ease of Use (Headlight and Battery)

Comfort of the Zeon Discovery with respect to headlight size and weight was rated as excellent by 2 evaluators, as very good by 5, as good by 1, and as fair by 1. One of the 2 dentists who found it “a little heavy” later “retro-mounted it to an old head band, which was very comfortable.” An Antioch, TN dentist who “couldn’t feel it on my loupes” said he “loved the light but there needs to be a better feature for taking it off and on.” One evaluator described it as “light weight with unstable attachment to connect to loupes” and another said it had a “very light feel, like it should have been part of the loupes to start with.”

The battery’s light control and output run time were rated as excellent by 2 evaluators, as very good by 6, and as good by 1. Two evaluators suggested inclusion of a second battery, 1 found the pack “a little heavy,” and 1 called it “light and comfortable… easily recharged.” One dentist did not find the brightness controls useful but added, “You turn it on and it’s full power every time.” Another evaluator said, “Working all day on 1 charge is pretty good.”

Overall Satisfaction

Eight evaluators said they would definitely or probably recommend the Zeon Discovery to colleagues. Overall satisfaction was rated as excellent by 2 evaluators, as very good by 5, and as fair by 2. One evaluator “loved having so much light for surgery, endodontics, and routine procedures.” Another dentist said, “I wear my light 5 to 7 hours a day. The quality of light is so superior to overhead, handpiece fiberoptics, etc, that I can’t believe I was able to produce quality dentistry without it.”
